Myofascial pain is prevalent chronic pain disorder that is comorbid with many conditions. Strengthening and stretching exercises are capable of inducing hypoalgesic effects in people with myofascial pain syndrome. The goal of this systematic review was to summarize the effects of aer-obic exercise on the management of myofascial pain. A comprehensive database search was conducted. A total of 1,331 articles were identified for review. One article was eligible for inclusion after full screening. Risk of bias was assessed using the Downs and Black quality assessment questionnaire (1998). Mean difference scores were calculated for con-tinuous variables. The identified study had a low risk of bias. It was a randomized controlled trial assessing the influence of an 8-week water aerobic exercise program on myofascial pain in breast cancer patients. Visual analogue scale pain intensity ratings and the number of myofas-cial trigger points present in the neck and shoulder/axillary area of par-ticipants significantly decreased in the exercise group compared to those in the control group. Pain pressure thresholds significantly in-creased in muscle areas of the cervical spine in the water exercise group. Aerobic exercise presents a potential treatment modality for managing myofascial pain. Additional research is necessary.

Brain inflammation is involved in many brain disorders, such as brain ischemic injury, Alzheimer diseases, and Parkinson disease. Physical exercise has been recommended for the prevention and treatment of many brain inflammatory diseases. In the present study, the effects of exercise on motor function in relation with apoptotic neuronal cell death following neuroinflammation were investigated. Moreover, we compared the effect of forced exercise with voluntary exercise on neu-roinflammation-induced motor malfunction. For this study, rota-rod test, vertical pole test, foot fault test, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, immunohistochemis-try for caspase-3, and western blot for Bcl-2 and Bax were performed. Lipopolysaccharide was intraventricular infused for induction of brain inflammation. Treadmill exercise and wheel exercise were conducted during 6 weeks. In the present results, Treadmill exercise and wheel ex-ercise alleviated brain inflammation-induced motor impairments by suppressing apoptotic neuronal cell death in the motor cortex. These effects of treadmill exercise and wheel exercise were similarly ap-peared.

Aging is a risk factor for heart disease and heart failure, which result from a progressive impairment of cardiac functions, including stroke volume, cardiac output, blood flow, and oxygen consumption. Age-re-lated cardiac dysfunction is associated with impaired cardiac struc-tures, such as the loss of myocytes, structural remodeling, altered cal-cium (Ca2+) handling, and contractile dysfunction. However, the mecha-nism by which aging affects mitochondrial function in the heart is poorly understood. The purpose of this study was to determine the effects of aging on mitochondrial function in the rat heart. Male Fischer 344 rats were randomly assigned to very young sedentary (VYS, 1 month), young sedentary (YS, 4 months), middle-aged sedentary (MS, 10 months), and old sedentary (OS, 20 months) groups. mitochondrial complex protein levels and mitochondrial function (e.g., mitochondrial hydrogen perox-ide (H2O2) emission and Ca2+ retention capacity) were analyzed in the left ventricle. Aging was associated with decreased levels of OXPHOS (oxidative phosphorylation) protein expression of complex I to IV in the function of the electron transport chain. Aging increased the mitochon-drial H2O2 emitting potential in the heart. In contrast, mitochondrial Ca2+ retention capacity gradually decreased with age. These data demon-strate that aging impairs mitochondrial function in cardiac muscle, sug-gesting that mitochondrial dysfunction with aging may be a primary factor for aging-induced cardiac dysfunction in the heart.

Sciatic crushed nerve injury (SCI) causes pain-related gait and swelling in the affected limb. Electroacupuncture (EA) is a modified acupuncture technique, and analgesic effect of EA on different types of pain has been documented. Scientific functional index (SFI) is a mathematical formula to represent parameters of normal and experimental footprints. We investigated the effect of low-frequency EA on functional recovery following SCI in rats. For this study, immunohistochemistry for c-Fos in the ventral lateral periaqueductal gray (vlPAG) and paraventricular nu-cleus (PVN) and western blot for neurofilament (NF) and brain-derived neurotrophic factor (BDNF) in the sciatic nerve were conducted. To in-duce crush injury on the sciatic nerve, sciatic nerve was crushed for 30 sec using a surgical clip. The rats in the acupuncture groups received acupuncture bilaterally at respective site, once a day for 14 days. The rats in the EA group received 100-Hz electrical stimulation for 10 min once a day during 14 days. SCI decreased SFI value, in contrast, EA in-creased SFI value. c-Fos expression in the vlPAG and PVN was in-creased following SCI, in contrast, EA suppressed c-Fos expression. NF expression in the sciatic nerve was decreased by SCI, in contrast, EA increased NF expression. BDNF expression in the sciatic nerve was in-creased by SCI, in contrast, EA suppressed BDNF expression. In the present study, EA showed effectiveness on functional recovery from SCI.

The purpose of this study was to determine the effects of the differenc-es in subfactors of communication competence on exercise participa-tion types (clubs, applications use). Communication competence focus on the communication part of the individual’s interpersonal compe-tence. Therefore, communication competence can be predicted to be related to the type of exercise participation. Accordingly, the targets of this study were clubs, which had group characteristics, and fitness ap-plications, which had individual characteristics. There was a significant difference as a result of the association between communication com-petence and the type of exercise participation. In terms of club mem-bership, significant differences were found in communication compe-tence skills according to exercise participation types in that self-disclo-sure of subjects who joined clubs was significant, social relaxation of subjects who intend to join a club was significant, and the immediacy of fitness applications users was significant.

This study measured balance ability using both an existing clinical test tool, the Y-balance test (YBT), and an automated version of the YBT named the dynamic balance test (DBT) developed in this study. Correla-tions between the two methods were examined to determine whether the DBT can be used as an objective tool for balance ability evaluation. The subjects included in the study were 32 healthy male adults in their 20s, who were randomized into two groups, YBT and DBT, to compare the balance ability between the two groups. The maximum stretching distances of both legs in the anterior (AT), posteromedial (PM), and pos-terolateral (PL) directions were measured. Furthermore, to compensate for the difference in length between left and right legs, the mean and standard deviations were determined using the standardization formu-la, and the standardized values were represented as percentages. For the statistical analysis of the data, an independent t-test was performed using SPSS ver. 18.0. The test results showed no significant differences between the two groups in both left and right legs in the AT, PM, and PL directions (P>0.05). Therefore, measuring balance ability with the DBT, which uses digital sensor measurement technology (an automated data recording, wireless data transmission, storage, and management sys-tem; measurement is possible even by one subject of balance ability test), was found to be advantageous in respect to the YBT in terms of time, efficiency, and convenience.

In order to investigate the effects of body image, commitment, and atti-tude on behavior after purchase of the Pilates consumers, this study sampled adults who were participating in the exercise at a Pilates cen-ter. By using the convenience sampling method, the data of 253 persons were analyzed. In relation to the appearance orientation and physical satisfaction, which are subfactors of the body image of a Pilates con-sumer, commitment and appearance evaluation have significant effects on attitudes, such as additional effort and satisfaction. Trust, appear-ance evaluation, and body satisfaction have significant effects on rec-ommendation, appearance orientation, and appearance evaluation of postpurchase behavior. Body satisfaction has a significant effect on the duration of the exercise after purchase. Commitment of Pilates con-sumers has a significant effect on attitudes, such as additional effort and satisfaction, while trust and commitment have significant effects on the recommendation to others after purchase and the duration of the exercise. Therefore, a program based on the basic principles of Pi-lates that can increase the interest and demand of the customers, and a systematic exercising method for improving the health of the custom-ers are deemed necessary. These will help customers in having a posi-tive attitude by creating a positive body image and increasing their en-gagement. In addition, these can convey positive images about Pilates and encourage customers to spend time on working out regularly by fulfilling their value and increasing their quality of life.

Handball is a popular sport in many countries. There is lack of knowledge about handball athlete’s functional movement capacity. The aim of this study is to investigate the Functional Movement Screen (FMS) scores, to evaluate the injury risks of handball athletes and to determine its relationship with athletic performance. A total of 51 professional handball players were included in this study. The sport-specific features and demographic data were recorded. The functional movement analysis was performed, agility and balance and force were evaluated. 37 were females and 14 were males. The mean age 21.00± 4.50 years (range, 16–35 years). The mean FMS scores of handball athletes were 12.86± 2.57. In addition, asymmetries were found between the left and right side FMS scores. There was a statistically significant poor correlation between the FMS and agility (r= 0.292, P= 0.038) and balance (right: r= 0.224, P= 0.024; left: r= 0.228, P= 0.022). Handball is a risky sport for injuries; therefore, athletes, coaches, and medical staff should recognize about the removal of functional deficiency before performance training. The FMS is a useful and cost-effective approach to identify these deficiencies. It is necessary not only to prevent injuries, but also to improve performance. These tests must be done before every season and, then, corrective, medical, or conservative approaches may be applied to athletes before performance training. (Clinical Trial ID: NCT03468569)

Plyometric training is a training method to increase the motor output, stretch-shortening cycle which could be associated with power output. To increase the neuromuscular output, various training variables have been incorporated in training programs. Weight vest is one of the vari-ables to develop it. However, how much load can effectively develop the neural response is still not clearly understood. The aim of this study was to identify the effects of additional external loads on neuromuscu-lar response of lower body during plyometric jump. Total 19 men per-formed jump tests with weight vest (two jumps in each additional load; 0%, 10%, 15% and 20% of bodyweight [BW]). During the tests, neuro-muscular responses of lower extremity were measured. In vertical jump, 0%BW group was higher than the other heavier loads. In rate of force development (RFD), 10%BW was higher than 15%BW and 20%BW. In 0–30 msec of interval RFD, the heavier load groups were greater than 0%BW and in 0–50 msec, 15%BW and 20%BW were higher than 0%BW. In neuromuscular efficiency (NME), 15%BW and 20%BW were greater than 0%BW in ankle joint. This research indicated that plyometric jump with additional load causes greater RFD and NME of lower extremity compared with jump training without additional load. During weight vest plyometric jump, 10%–20% of BW load is advantageous to NME of lower body and 10% of BW load is effective to develop RFD of lower extremity.

The aims of this study were to compare the maximal isometric handgrip strength of judo athletes from different weight categories and to create a classificatory table for this test. A total of 406 athletes had their maxi-mal isometric handgrip strength measured, following standardized rec-ommendations. Absolute and relative values were calculated for each hand and for the sum of both hands. Weight categories were compared through a one-way analysis of variance, followed by Tukey test. The ef-fect size was determined by partial eta squared, and the relationship between variables was determined using Pearson correlation coeffi-cient. There was a large effect of weight category in absolute handgrip strength for each hand and for the sum of both hands, with lower values for the lighter categories. Conversely, when the relative strength was considered higher values were found for the lighter categories (P<0.001). Very large and significant positive correlations (P<0.001) were found between right and left for absolute (r=0.886) and relative (r=0.883) handgrip values. Overall, there was an increase in absolute and a decrease in relative handgrip strength across weight categories. These differences found in grip strength in weight categories are prob-ably linked to differences in muscle mass between them. There was a high correlation between each hand for absolute and relative values, which suggests that assessing only one hand may be enough, and therefore a faster way of evaluation. Finally, the normative classificatory table created may serve as a reference for different purposes.

Identification of the body fat (BF) percentage allows health professionals to detect healthy or risky patterns in a population. However, no studies have elaborated BF cutoff points using the bioelectrical impedance method in young Brazilian adults. Thus, the objective of the present study was to elaborate normative tables for BF in Brazilian men and women (sedentary and physically active) between 18 and 39 years of age. A total of 3,111 adults (958 men and 2,153 women) were evaluated using bioimpedance measurements with the InBody 520 device. The data were distributed normally and divided into percentiles (P3, P10, P25, P50, P75, P90, and P97). The following values were observed: for men: P3 =8.9%–12.5%; P10 =12.6%–17.5%; P25 =17.6%–25.3%; P50 =25.4%– 35.1%; P75= 35.2%–43.0%; P90= 43.1%–49.4% and P97= 49.5%; for women: P3= 18.7%–23.1%; P10= 23.2%–28.7%; P25= 28.8%–35.7%; P50= 35.8%– 42.9%; P75= 43.0%–49.1%; P90= 49.2%–52.1% and P97≥ 52.2%. These percentiles can be used to classify the adiposity of sedentary and physically active individuals evaluated by bioimpedanciometry.

The purpose of this study was to investigate the effects of low-pressure hyperbaric oxygen (HBO) treatment before and after maximal exercise on lactate concentration and heart rate and antioxidant capacity. Ten healthy male college students were recruited from amateur soccer players. Subjects were performed a maximal exercise 3 times at inter-vals of at least 7 days according to the treatment method (control, pre-treatment, posttreatment). Lactate concentration, heart rate, and anti-oxidant capacity were measured before, post, and after recovery 30 min of maximal exercise. The lactate concentration and heart rate of recovery 30 min was significantly lower in the low-pressure HBO treat-ed group after the maximal exercise compared with the control group and the low-pressure HBO treated group before maximal exercise, and it could affect the removal of the fatigue substance caused by the maxi-mal exercise. These results suggest that the low-pressure HBO treat-ment which is a new possibility for recovery of peripheral fatigue.

This study was designed to investigate the effects of β-alanine (BA) supplementation on peak power, power drop, and lactate response in elite male amateur boxers. Nineteen male Korean national team boxers were divided into groups with either BA (n=9) or placebo (PL, n=10) supplementation. BA consumed 4.9–5.4 g/day of BA with training for 10 weeks and PL took PL in a similar manner. Physical fitness and lactate changes in sparring were measured before and after the 10-week inter-vention. Significant interactions (P<0.05) were shown for lower body peak power (P=0.049) and upper body power drop (P=0.042). Positive effects for the BA group were shown for lower body peak power (Co-hen d=0.72; 95% confidence interval [CI], 0.09–1.35) and the mainte-nance of upper body power output (d=-0.91; 95% CI, -1.61 to -0.17). These findings suggest that Korean national amateur boxers who con-sumed BA demonstrated differential responses following a training in-tervention in specific physical fitness when compared to boxing ath-letes who consumed a PL.

The purpose of this study to investigate how gait velocity and variability were affected by dual task prioritization in older adults with normal cog-nitive function and older adults with mild cognitive impairment (MCI). Eight older adults with MCI and eight cognitively normal older adults performed a walking task under usual walking with no dual task (usual gait), walk while counting backward from 100 by ones with no priority on task (no priority), walk and count while instructed to prioritize gait task (gait priority), and walk and count while instructed to prioritize the cognitive task (cognitive priority). The MCI group showed significantly slower walking speed than the normal group in the no priority condition, but no difference between both group in the usual gait condition, and they almost 3 times greater gait variability in the no priority condition than the normal group. For the effect of priority instructions, MCI group showed a dual-task cost to gait velocity almost 2 times higher than that of the normal group in the no priority condition, but the cost was almost three times higher in both gait and cognitive priority conditions. Although there was no interaction effect for gait variability, MCI group tended to be more influenced by dual task prioritization than the normal group. Our findings confirmed that the priority-based dual task paradigm is a valid way to assess gait characteristics of people with cognitive problems.

This study was executed as correlation study to investigate the correla-tion between the dimensions of diaphragm movement, and respiratory functions and pressures in accordance with the Gross Motor Function Classification System (GMFCS) levels on children with cerebral palsy as the participants. Forty-three children in the age range of 5–13 years di-agnosed with cerebral palsy as the research participants were divided into three groups (levels I, II, and III) through systematic stratified ran-dom sampling in accordance with their GMFCS levels. Pearson correla-tion analysis was executed to examine the correlation between dimen-sions of diaphragm movement, and respiratory functions and pressures in accordance with the GMFCS levels of the participants. There was no significant correlation between the dimensions of diaphragm move-ment, and respiratory functions and pressures in all of the three groups in accordance with the GMFCS levels of the participants. Therefore, it is deemed that although measurement of the dimensions of diaphragm movement of children with cerebral palsy by using diagnostic ultrason-ic M-mode imaging device can be considered as auxiliary tool in pre-dicting the breathing capabilities, it cannot be used as independent measurement equipment.

The purpose of this study was to examine the effects of Vojta approach on the gross motor function and diaphragm movement in children with spastic cerebral palsy (CP). Ten children with spastic CP were randomly assigned to a general physiotherapy group (trunk strengthening exer-cise and gait training) (n=5) and a Vojta approach group (n=5). Inter-ventions were implemented for 30 min per time, 3 times a week for a to-tal of 6 weeks. Ultrasonography was used to measure the areas of the diaphragm (during inspiration, expiration) before and after the interven-tions, the gross motor function measure (GMFM)-88 was used for eval-uation of the gross motor function. In the results of this study, there was a significant difference between before and after GMFM-sitting in the experimental group (P<0.05), a significant difference in changes of in-spiration between the two groups (P<0.05). Given these results, Vojta approach may be presented as an effective treatment method for im-proving sitting position and diaphragm movement during inspiration in children with spastic CP.

The purpose of this study was to investigate the effects of coordinative locomotor training (CLT) on coordination and gait in chronic stroke pa-tients. Thirteen stroke patients were randomly assigned to one of two groups: The experimental group (EG, n=7) and control group (CG, n=6). After balanced random assignment, interventions were provided to all patients in twelve 30-min sessions during a 4-week period (3 sessions a week). The EG group underwent CLT after performing the sprinter and skater patterns in four postures. The CG group was provided with con-ventional neurodevelopment treatment. The primary outcomes were measured using the gait assessment and intervention tool (GAIT) as well as G-WALK. The secondary outcomes were measured using a 10-m walk test (10 MWT) and Timed Up and Go Test. There was no sta-tistically significant difference in the mean values between the two groups. Within both groups there were significant differences in GAIT and 10MWT. There were significant differences in gait speed and stride length in the experimental group, but not in the control group. CLT showed a more positive improvement in gait and coordination after stroke than conventional rehabilitation exercise.

Age-related skeletal muscle changes may impact respiratory muscle function, and low muscle mass is associated with low pulmonary func-tion in older adults. Stroke not only causes weakness in the muscles of the upper and lower limbs, but it can also affect the respiratory system. This study aimed to investigate the relationships between grip strength and pulmonary function and respiratory muscle strength in stroke pa-tients over 50 years of age. Fifty-one patients (68.69±10.40 years) who had been clinically diagnosed with ischemic or hemorrhagic stroke were included in this study. We measured these patients’ forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and hand grip strength. The data were analyzed using descriptive statistics and Pearson correlation analysis. Grip strength showed significant correlations with FVC (r=0.686, P=0.000), FEV1 (r=0.607, P=0.000), PEF (r=0.494, P=0.000), MIP (r=0.239, P=0.091), and MEP (r=0.348, P=0.012). This study demonstrated that grip strength is associated with pulmonary function and MEP in stroke patients over 50 years of age.

Fear of falling and balance impairment are prevalent in older adults and cause major morbidities for this population. The aim of this study was to evaluate the effect of Tai Chi Chuan on balance and fear of falling in community-dwelling older adults. This study was a single-blind random-ized control trial. Sixty older adults were randomly allocated into two groups using a 4-cell random block design. The participants of interven-tion group were trained in Tai Chi Chuan for eight weeks, twice a week, and 55 min in each session. Balance and fear of falling were assessed by Timed Up and Go (TUG) test, Tinetti test and Falls Efficacy Scale In-ternational in baseline and after 8 weeks. After eight weeks of interven-tion, the mean scores of the TUG and Tinetti scales in the intervention group were improved significantly compared to the baseline and the control group (P<0.001). Moreover, the intervention group showed a significant reduction in fear of falling scores (P<0.001), while those in the control group remained unchanged. Tai Chi Chuan effectively im-proves the balance and fear of falling and could be considered as a practical and useful method for fall prevention in community-dwelling older adults.

This study aims to identify the effects of exercise type on estrogen, tu-mor markers, immune function, antioxidant function, and physical fit-ness in postmenopausal obese women. The subjects were 30 post-menopausal obese women with body fat percentage higher than 30%. Participants were divided into aerobic exercise group (n=10; age, 53.70±3.37 years), resistance exercise group (n=10; age, 52.20±2.15 years), and control group (n=10; age, 52.50±2.68 years). Estrogen and growth hormone showed no significant difference in the aerobic exer-cise group, resistance exercise group, and control group. Tumor marker alpha-fetoprotein was increased in the aerobic exercise, resistance ex-ercise, and control groups (P<0.01). The metabolic syndrome risk factor was decreased in the aerobic and resistance exercise groups, which was shown by the reduction of weight (P<0.001), body fat percentage (P<0.001), waist circumference (P<0.05), and increase of high density lipoprotein-cholesterol (P<0.001). natural killer cell activity was in-creased in the aerobic exercise group, resistance exercise group, and control group (P<0.001). Oxidative stress was decreased in the aerobic exercise group, resistance exercise group, and control group (P<0.001). Maximum oxygen uptake was increased in the aerobic and resistance exercise groups, but aerobic exercise was more effective (P<0.05). Knee isokinetic extensor muscle was increased in both the aerobic and resistance exercise groups (P<0.001). Aerobic and resistance exercise of postmenopausal obese women can be considered an effective inter-vention program to prevent metabolic syndrome and improve physical fitness.

To clarify the significance of mechanical impairments, pain, and func-tional limitations as predictors of chronic low back pain (LBP). Ninety patients with chronic nonspecific low back pain (CNSLBP) were pro-spectively studied with clinical tests and questionnaires. Changes in muscle extensibility and endurance tests were evaluated and changes assessed in LBP intensity on numeric rating scale 0–10 and severity with Oswestry Disability Index (ODI) 0–100. In the present study we found significant associations between the 4 muscle extensibility and 2 endurance tests and pain at nonspecific patients with chronic LBP (P<0.005). The 2 muscle extensibility and 1 endurance tests were in complete equilibrium with ODI disability and hence showed similar re-sults (P<0.005). The associations between the muscle extensibility and endurance tests and pain were significantly elevated in patients with nonspecific chronic LBP.

The aim of the study was to determine the effect of physiotherapy and minimal invasive technics (MIT) on pain, quality of life and functional disability in geriatric patients with chronic low back pain. According to previous files, 61 geriatric patients who received MIT and physiothera-py allocated to group 1, the patient who received physiotherapy alone allocated to group 2. All patients received soft tissue mobilizations, muscle-energy technics and spinal stabilization exercises. Pain severi-ty, functional disability, life quality, and fear avoidance were assessed with visual analogue scale, Oswestry Disability Index (ODI), Nottingham Health Profile (NHP) and Fear Avoidance Beliefs Questionnaire, respec-tively. Improvements in ODI and NHP were seen in favor of group 2 after treatment as to baseline (P<0.05). Although both treatments showed pain relief, functional restoration, and improvement in quality of life; there was no additional improvement in patients received MIT different from the patients received physiotherapy alone.

Stability exercise (SE) and balance exercise (BE) are generally-applied clinical interventions for back pain. For a proper clinical application, it is necessary to characterize and compare the effects of SE and BE on low back pain (LBP). The purpose of this study was to compare the ef-fects of SE and BE on the activity of trunk muscles in women with chronic LBP. Women with chronic LBP (n=30) who volunteered for this study were randomly divided into two exercise groups of 15 partici-pants. We obtained pre- and postintervention data through application of the visual analogue scale (VAS), Oswestry Disability Index (ODI), and electromyography (EMG). While post-intervention EMG showed de-creased activity of the external oblique (EO) in the SE group, the EMG results in the BE group showed increased EO activity (P<0.05). Both groups had increased muscle activity of the erector spinae (P<0.05). Both groups showed significant reductions on the VAS and ODI (P<0.05). Both SE and BE were effective in reducing pain in the study participants. The decrease in EO muscle activity in the SE group seems to be due to the SE inducing cocontraction and distributing the role of the EO to other muscles. In contrast, EO muscle activity was increased in the BE group. It appears that the EO is important in maintaining the center of gravity and base of support during BE. The role of EO seems to maintain trunk stability as it increases muscle activity of EO.

This study aimed to investigate the effect of ancient boxing exercise on the strength of leg muscles and quality of life in patients with osteoar-thritis. The subjects were divided into 2 groups, control group (CG) and experimental group (EG). The average aged of control and experimental group were 60.3±6.8 and 59.0±7.8 years, respectively. All volunteers were interviewed for basic information, evaluation of the criteria of re-search and sign consent to participate in the research. The outcome measurement consisted of five time sit to stand test, 6-min walk test, flexibility by sit and reach test, Berg Balance Scale, Timed Up and Go Test, knee injury and osteoarthritis outcomes score (KOOS) and quality of life of World Health Organization Thai brief version (WHOQOL-BERF-THAI). Prior and posttest measurements were performed at 0, 4, 8, and 12 weeks, and those who received ancient boxing exercise were given 60 min 3 times per week for 12 weeks. The results of the study showed that postexercise leg muscle strength, physical performances, quality of life and KOOS increased significantly after exercise. In conclusion, the ancient boxing exercise could increase the strength of leg muscles physical performances, quality of life in people with knee osteoarthritis. This exercise can be used as a long lasting exercise in the future.

Carpal tunnel syndrome (CTS) is one of the reasons for labor abandon-ment due to inability and pain. The aim of this study was to evaluate the effectiveness of gabapentin and exercise training in the treatment of CTS and compare their effects. This single-blind clinical trial was con-ducted on patients referred to the Imam Hossein hospital’s electrodiag-nostic (EDX) unit. The patients randomly assigned into four groups: us-ing nocturnal splint as an approved treatment in the control group; tak-ing 300-mg gabapentin per night and using nocturnal splint; nerve and tendon gliding exercises and using nocturnal splint; and taking 300-mg gabapentin per night, performing same exercise as group 3 and using nocturnal splint. At baseline, four indicators were assessed in all pa-tients, including the Boston carpal tunnel questionnaire, visual ana-logue scale (VAS), pinch and grip strength of the affected hand. One month after the beginning of intervention, participants were reassessed and compared for each of the four indicators. Using nocturnal splint along with exercise and gabapentin significantly improved VAS, pinch and grip strength in moderate CTS compared to control group that only used nocturnal splint. However in mild CTS, grip strength was not sig-nificantly higher compared to control group (P=0.048). Results of this study showed that use of splint alone in mild CTS is an appropriate and sufficient treatment; however, in moderate CTS, receiving gabapentin along with exercise and splinting showed better treatment results com-pared to splinting alone.

The purpose of this study was to determine the effect of therapeutic ex-ercise for a woman with temporomandibular joint disorder. She was 31 year old and had limitation in the opening of mouth. When opening the mouth, she complained pain in the temporomandibular joint and noise. The health status of the patient was classified based on International Classification Functioning, Disability, and Health regarding the activity of the patient. The activity limitation was determined by the ability of opening the mouth, while the impairments in the body structure and body function were determined by the forward-headed posture due to the hypertension and shortening of upper cervical extensors. The pro-prioceptive neuromuscular facilitation (PNF) program consists of eight types of therapeutic exercises considering the alignment of the cervical spine and the pain in the temporomandibular joint. The application of the PNF program was composed of 12 sessions over 4 weeks and each session continued 30 min. Before and after the application of the PNF program, the up-down length and the left-right width of the bite mark on the apple were measured (activity limitation test). The length of the ap-ple that was bitten was measured using a tape measure (activity limita-tion test). The test on the abnormal alignment of the cervical spine was conducted using a plastic goniometer to measure the angle to the cer-vical spine (impairment test). After a 4-week PNF program, patient could open mouth wide without pain. The present results suggest that PNF program can be used to enhance the stability and mobility of the tem-poromandibular joint. With this, the impairment in the body structure and body function and activity of patient were improved.

The objective of the present study was to examine the effects of differ-ent muscle contraction interventions using isokinetic dynamometers on the muscle recovery after muscle injury caused by eccentric exercise. A total of 28 healthy male adults participated in the present study and each subject was randomly assigned to eccentric muscle contraction (EC, n=7), concentric muscle contraction (CC, n=7), both eccentric and concentric muscle contraction (BEC, n=7), and control (CON, n=7) groups after performing eccentric exercise. In all groups, except the control group, a different type of muscle contraction intervention was applied repeatedly for 24–96 hr after eccentric exercise, and maximum strength, muscle soreness, and creatine kinase (CK) levels were mea-sured. The results showed a significant association between time and group, with respect to maximum strength (P<0.05), muscle soreness (P<0.001), and CK (P<0.001) after eccentric exercise. Moreover, BEC group showed faster muscle recovery than other groups. In conclusion, implementing active strategies such as performing BEC using an isoki-netic dynamometer after eccentric exercise may be effective in facili-tating muscle recovery.
