To review and systematically summarize the psychometric and clinical properties (reliability, validity, responsiveness) of the Timed Up and Go test applied to persons diagnosed with Parkinson disease. A systematic review was performed by screening four scientific databases (MED-LINE, CINAHL, and PubMed). Independent reviewers selected and ex-tracted data from articles that assessed the reliability, validity, sensitivity to change, and/or clinical properties of the Timed Up and Go test in per-sons with Parkinson disease. Twenty-four studies were selected. Nine analyzed reliability and yielded “good” to “moderate” scores. Seven-teen used a range of different contrast tests to assess validity of the Timed Up and Go test and found “good” quality scores in those that as-sessed balance. Only two studies analyzed sensitivity to change and they reported “poor” quality scores. The use of Timed Up and Go in Parkinson disease patients presents good reliability and validity (when compared to tests that assess balance).

Poststroke subjects present with difficulties of reduced functional mobility and balance. Trunk impairment is common among stroke subjects which hinder the performance of upper and lower limb. In poststroke rehabilitation limbs are provided much attention than the trunk. Trunk function has been identified as an important early predictor of functional outcome after stroke. Physioball is commonly used among healthy subjects in performing trunk exercises. This systematic review with meta-analysis is conducted to investigate the effect of trunk exercises performed using physioball in improving trunk performance after stroke. Six authors identified relevant articles from the following databases: PubMed, Google Scholar, CINAHL (Cumulative Index and Nursing and Allied Health Literature), PEDro (Physiotherapy Evidence Database). Articles evaluating the effect of physioball exercise for improving trunk stability among stroke subjects were included. Databases were screened from 2009 and up to 2019. Qualitative synthesis of evidence was prepared and meta-analysis was implemented to draw pooled effects of physioball exercise on improving trunk performance and balance among stroke subjects. Eight papers were included, totaling 273 participants. All the articles included in this review demonstrated moderate to good quality. Meta-analysis performed with seven papers demonstrated statistical significance of physioball in improving trunk performance during acute and subacute stages of stroke. Brunnel Balance Assessment outcomes demonstrated statistically significant improvement of balance among overall stroke survivors. Trunk exercise performed over a physioball is effective during the acute and subacute stage. This meta-analysis could not find its significant effect in improving trunk performance in the chronic stages.

Tensiomyography (TMG) is an injury detecting tool for muscle group im-balances and/or side-to-side asymmetries. It is liable to detect to mea-sure contractile properties and mechanical responses based on mus-cle belly displacement. Although other previous papers have well sug-gested the methods for examining the several muscle groups using TMG, a detecting method for the imbalances in low back muscles has not been investigated, and no review papers have been compiled. Therefore, this study aimed to synthesize the theories of the previous studies observed using TMG and to briefly summarize its usefulness by performing simple experiments on the left and right regions of the erec-tor spinae muscles, which may be a problem using TMG for patients with low back pain.

The purpose of this study is to explore the feasibility and therapeutic potential of creative dance (CD) based exercise as a rehabilitation intervention for adolescents with cerebral palsy (CP). Participants were 10 adolescents with spastic CP (mean age, 17.5± 2.12 years; Gross Motor Function Classification System levels I [n= 3] and II [n= 7]). Outcome measures included the Gross Motor Function Measure-88 (GMFM-88; dimensions D and E), spatiotemporal gait parameters, lower limb range of motion during walking, and body image, assessed using the Body Cathexis Scale (BCS). CD was provided in 2-hr classes, twice weekly, for 12 weeks, during which participants learned movement concepts and developed their own movement. All participants completed the intervention, with an attendance rate of 98% and high satisfaction rating. GMFM-88 dimensions D (P= 0.01) and E (P= 0.005); walking speed (P= 0.005), cadence (P= 0.009), step (P= 0.005), and stride length (P= 0.005); and sagittal ranges of motions of hip (P= 0.009) and ankle (P= 0.03) during walking were significantly improved. The time of opposite foot off (P= 0.028) and first double-limb support (P= 0.028) significantly decreased, whereas the percentage of single-limb support time (P= 0.02) increased. Additionally, BCS scores were significantly improved. In conclusions, CD-based exercise can improve gross motor function, gait performance, and body image in adolescents with CP.

Considering the occurrence of gait impairment following stroke, walk-ing recovery is an important goal of rehabilitation. Ground reaction force (GRF) is used for gait assessment of rehabilitation progress during exercise in stroke patients. The aim of this study was to compare the GRF during gait of the nonparetic side in hemiparetic patients and the dominant side in healthy subjects. Twenty hemiparetic patients and 20 healthy subjects were enrolled in the study. Force plate was used to evaluate GRF during gait. Additionally, with the patients and subjects in supine position, we measured their range of motion (ROM) in ankle dor-siflexion using a digital goniometer. The force values of stance phase on the nonparetic side of hemiparetic patients were significantly less than on the dominant side of healthy subjects (P<0.05). The impulse values of stance phase on the paretic side and the nonparetic side of hemiparetic patients were significantly greater than on the dominant side of healthy subjects (P<0.05). The ankle ROM result was signifi-cantly correlated with the GRF values (P<0.05). It is important to assess and understand the nonparetic side as well as paretic side. These re-sults suggest that the analysis of GRF for exercise rehabilitation will be a valuable clinical evaluation in hemiparetic patients after a stroke.

The purpose of this study was to examine the relationship between physical fitness and psychological well-being, stress, and depression in Korean adults. Participants were 160 adults aged 40–70 years living in the metropolitan area of Incheon. Results were collected from random sample of main measurements from Incheon fitness center of National Fitness Award Project (2019). We assessed participants using physical fitness test (national fitness award), Psychosocial well-being index short form, Perceived Stress Scale, Geriatric Depression Scale. The data were analyzed Pearson and Spearman rank correlation analysis, and linear was conducted using IBM SPSS Statistics ver. 25.0. The re-sults indicated there were statistically significant associations between psychological well-being and agility, quick response; stress and flexibil-ity; depression and strength endurance strength, body fat. In addition, analysis showed that strength, endurance strength, body fat of physical fitness factors could significantly predict depression, flexibility could significantly predict stress, agility and quick response could significant-ly predict psychological well-being.

High-intensity exercise, marathons, and long distances triathlons have been shown to induce the fatigue of respiratory muscles (RMs). Never-theless, fatigue and the recovery period have not been studied in re-sponse of an Olympic distance triathlon (1.5-km swim, 40-km bike, 10-km run: short-distance triathlon). The aim of this study was to evaluate the RM fatigue induced by an Olympic distance triathlon. Nine male triath-letes (24±1.1 years) underwent spirometric testing and the assessment of RM performance. Respiratory function tests were conducted in sit-ting position. Spirometric parameters, maximal inspiratory and expirato-ry pressures, and RM endurance assessed by measuring the time limit were evaluated before (pre-T), after (post-T), and the day following the triathlon (post-T-24 hr). Residual volume increased: pre-T vs. post-T (P<0.002), maximal inspiratory pressure significantly decreased from 127.4±17.2 (pre-T) to 121.6±18.5 cmH2O (post-T) (P<0.001) and returned to the pre-T value 24 hr after the race (125.0±18.6). RM endurance sig-nificantly decreased from 4:51±0:8 (pre-T) to 3:13±0:7 min (post-T, P< 0.001) and then remained decreased for 24 hr after the race from 4:51± 0:8 (pre-T) to 3:39±0:4 min 24 hr after (P<0.002). Both, strength and en-durance of inspiratory muscles decrease after Olympic distance triath-lon. Furthermore, the impaired of inspiratory muscle endurance 24 hr after the race suggested a slow recovery and persistence of inspiratory muscle fatigue.

Active straight leg raising (ASLR) is a fundamental test and used in the Functional Movement Screen (FMS). In the ASLR of the FMS, one sub-group performs the movement correctly without any compensation (ASLR-3), whereas another subgroup has limitations in ASLR but not the passive straight leg raising (ASLR-1-SMCD). We aimed to investigate whether abdominal muscle activities in ASLR are different between in-dividuals with ASLR-1-SMCD and ASLR-3. The relative latency of the onset of the following muscles to the right rectus femoris muscle during the right ASLR and the amplitude of activity in the following muscles for 50 msec after the onset of rectus femoris muscle activity were com-pared: left rectus abdominal, bilateral external oblique, bilateral internal oblique, and left gluteus maximus muscles. Data of 17 participants with ASLR-3 and 34 participants with ASLR-1-SMCD, whose sex ratio was matched to the ASLR-3 group, were analyzed. Those with ASLR-1-SMCD had statistically significant delays in the relative latency of the right internal oblique muscle (46.32±70.83 msec) and left gluteus maxi-mus muscle (100.36±75.40 msec) muscles compared with those with ASLR-3 (right internal oblique muscle=9.75±23.07 msec, left gluteus maximus muscle=57.50±36.89 msec). However, the difference in the amplitude of activity in any muscles was not significant. The ASLR-1-SMCD group had greater relative latency of the onset of right internal oblique muscle and left gluteus maximus muscle to the onset of the right rectus femoris muscle during the right ASLR compared with the ASLR-3 group.

Fitness centers are remarkably abundant in Cameroon. The aim of this work was to assess the effects of a 12-week training program on the anthropometric and physiological profiles of some participants in a fit-ness center. A total of 86 participants (40 from the experimental group and 46 from the control group) with age ranging from 17 to 53 years were subjected to pre- and posttraining assessments of, anthropomet-ric parameters, physiological parameters, and performance. Anthropo-metric parameters (weight, height, body mass index [BMI], waist cir-cumference [WC]) and blood pressure (diastolic blood pressure, systol-ic blood pressure [SBP]) were measured according to standard proto-cols. Heart rate was recorded using a heart rate monitor. Cardiorespira-tory fitness (maximal oxygen uptake or VO2peak) was estimated by the 20-multistage shuttle run test. All the data was collected twice within 12 weeks. Weight, BMI, and WC did not show any significant variation (P>0.05) after a 12-week training program. VO2peak increase was insig-nificant (P>0.05) higher in men (7.5%, P=0.06), compared to women (5.4%, P=0.4). We noticed a significant reduction (P=0.002) in the SBP of men. Significant increase of HR max was found in women. There was an improvement of 13.7% in the VO2peak of the participants who did not consume alcohol. These results demonstrate the slight benefits of a 12-week training program on health. The weight characteristics of the par-ticipants and lifestyle may play an important role in these interactions.

The purpose of this study was to comparatively analyze normal gait on the plains by gender for old people reference data for the normal gait pattern for the old people. Participants were selected according to the Korean standard body type provided by the Ministry of Health and Wel-fare and used a three-dimensional motion analysis system. Cortex, Or-thotrak, and Excel were used as the software for analyzing the extract-ed data, and IBM SPSS Statistics ver. 24.0 was used for statistical anal-ysis. When data standardization was performed using the dimension-less numbers conversion, the step length and stride length of the lower extremities, which had differences between genders before dimension-less numbers conversion, showed no difference after dimensionless numbers conversion. Cadence, step time, and single support time of the left lower extremity, which had no difference between genders before dimensionless numbers conversion, were found to have significant dif-ferences after dimensionless numbers conversion. In addition, as a re-sult of analyzing the coefficient of variation value to find out the degree of change in data due to dimensionless numbers conversion, there were increase and decrease in the coefficient of variation value rang-ing from -8.11% to 6.67% before and after dimensionless numbers con-version, which means dimensionless numbers conversion can affect the statistical test.
