From above results, balance ability of hockey players was shown to be improved through symmetric training of PNF combined pattern applied to hockey players, and it can be considered that this is actively recommended for training method to improve athletic performance of hockey players.

The aim of this study was to evaluate the effects of walking on a treadmill while using dynamic functional electrical stimulation (Dynamic FES) on functional ability and gait in chronic stroke patients. This was a prospective, randomized controlled study. Twelve patients with chronic stroke (>24 months) who were under grade 3 in dorsiflexor strength with manual muscle test were included and randomized into intervention (Dynamic FES) ($n_1$=7) and control (FES) ($n_2$=5). Both the Dynamic FES group and FES group were given a neuromuscular development treatment. The Dynamic FES group has implemented a total of 60 minutes of exercise treatment and gait training with Dynamic FES application. The FES group, with the addition of applying FES while sitting, has also implemented a total of 90 minutes of gait training on treadmill after the exercise treatment. Both two groups accomplished the program, twice a week, for a total of 24 times in a 12-week period. Exercise treatment, gait training on treadmill, and both Dynamic FES and FES were implemented for 30 minutes each. Korean version activities-specific balance confidence scale (K-ABC) was measured to determine self-efficacy in balance function. Timed up and go (TUG) test was performed to evaluate the physical performance. K-ABC, TUG, Berg balance scale (BBS), modified physical performance test (mPPT) and G-walk were evaluated at baseline and at 12 weeks. After 12 weeks, statistically significant differences (p<.05) were apparent in the Dynamic FES group in the changes in K-ABC and BBS. mPPT, TUG, gait speed, stride length and stance phase duration (%) were compared with the FES group. K-ABC had higher correlation to BBS, along with mPPT to TUG. Our results suggest that walking with Dynamic FES in chronic stroke patients may be beneficial for improving their balance confidence, functional ability and gait.

Objective To determine if assistive ergometer training can improve the functional ability and aerobic capacity of subacute stroke patients and if functional electrical stimulation (FES) of the paretic leg during ergometer cycling has additional effects.Methods Sixteen subacute stroke patents were randomly assigned to the FES group (n=8) or the control group (n=8). All patients underwent assistive ergometer training for 30 minutes (five times per week for 4 weeks). The electrical stimulation group received FES of the paretic lower limb muscles during assistive ergometer training. The six-minute walk test (6MWT), Berg Balance Scale (BBS), and the Korean version of Modified Barthel Index (K-MBI) were evaluated at the beginning and end of treatment. Peak oxygen consumption (Vo2peak), metabolic equivalent (MET), resting and maximal heart rate, resting and maximal blood pressure, maximal rate pressure product, submaximal rate pressure product, submaximal rate of perceived exertion, exercise duration, respiratory exchange ratio, and estimated anaerobic threshold (AT) were determined with the exercise tolerance test before and after treatment.Results At 4 weeks after treatment, the FES assistive ergometer training group showed significant improvements in 6MWT (p=0.01), BBS (p=0.01), K-MBI (p=0.01), Vo2peak (p=0.02), MET (p=0.02), and estimated AT (p=0.02). The control group showed improvements in only BBS (p=0.01) and K-MBI (p=0.02). However, there was no significant difference in exercise capacity and functional ability between the two groups.Conclusion This study demonstrated that ergometer training for 4 weeks improved the functional ability of subacute stroke patients. In addition, aerobic capacity was improved after assisted ergometer training with a FES only.

Purpose: In rapidly aging societies, preserving residents’remaining functional ability (RFA) has been emphasized in nursing home (NH) care. Assessing residents’remaining function is necessary for the planning of this process. This study was done to develop and test categorizing a tool by which the RFA of nursing home residents can be assessed in order to better address their care needs and to support nurses’practice. Methods: This study was conducted in three stages: in-depth interviews with NH nurses to develop a conceptual framework for categorizing the RFA, construction of preliminary items for the categorizing tool, and then testing the tool’s validity and reliability. One hundred ninety-seven residents from ten NHs representing Korea nationwide participated. Results: The RFA of the NH residents was classified as two dimensions: physical and cognitive function. Fifteen items were developed to categorize the tool for RFA. Correlations with long-term care levels and long term care assessment scores supported the scale's criterion validity. Reliability (Cronbach's ?, test-retest and inter-rater reliability) was acceptable. Conclusion: This tool can be used to promote effective nursing care by improving the RFA of NH residents. This tool can also be used by nurses in their daily routine NH care.

The Purpose of this study was to investigate correlations between the Mini-Mental State Examination (MMSE) and the Functional Independence Measure (FIM) in strokes. The data collected retrospectively from fifty-five stroke rehabilitation patients. The MMSE and FIM at the time of admission and discharge were obtained from patients' medical records. Firstly, Pearson correlation coefficients of the MMSE score at the time of admission revealed $0.286{\sim}0.747$ with FIM at the time of discharge (p<0.05). Also, the change of MMSE score significantly correlated with the change of total FIM scores in strokes (r=0.409, p<0.05). Because the MMSE scores at the time of admission and FIM at the time of discharge are correlated, the MMSE scores can be used to predict the FIM at the time of discharge and establish a rehabilitation program.

Purpose: The health of older people, especially functional ability, has become a hot topic for scholars invarious countries. There is insufficient research on the urbanerural disparity in the functional ability ofolder people. This study aimed to explore the urbanerural gap in the functional ability of older peopleand the related influencing factors. Methods: The data analyzed in this study were collected through a cross-sectional survey conducted inChina. Furthermore, binary logistic regression was utilized to assess the relationship between functionalability and the independent variables, and Oaxaca-Blinder decomposition was used to explore urbanerural differences in functional ability among older people. Results: The percentage of urban older people who were functionally robust was 65.9%, which wassignificantly higher than the rural 40.4%. Furthermore, our study identified factors affecting the functionalability of older people in urban areas, including age, body mass index, education, social participation,and trust. In contrast, for older people in rural areas, in addition to these factors, gender, drinking,and social connection were also found to be factors affecting their functional ability. Moreover, the resultsof the OaxacaeBlinder decomposition showed that the most critical factor influencing the urbaneruraldifferences in functional ability among older people was social participation (26.5%). Besides, education(14.4%), living status ( 10.8%), age (7.3%), and trust ( 6.9%) likewise influence the urbanerural disparity. Conclusion: A higher proportion of older people in rural areas have limited functional ability than thosein urban areas. Moreover, the disparity in social participation levels significantly contributed to thedifferences in functional ability observed between older adults in urban and rural settings. This studyunderscores the significance of enhancing the social engagement of older adults, particularly those livingin rural communities

PURPOSE: This study examined the efficacy of an interferential current (IFC) treatment on the improvement of pain, disability, and quality of life in stroke patients with lumbago. METHODS: A double-blind, randomized clinical trial was conducted on 40 stroke patients with lumbago. The patients were allocated randomly into two groups: the IFC treatment group (n= 20) and the placebo treatment group (n= 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment but without real electrical stimulation. The intervention was administered five days a week for four weeks. The primary outcomes of pain intensity were measured using a visual analogue scale. The secondary measurements included the Barthel Index, Oswestry Disability Index (ODI), and health-related quality of life (HRQoL). RESULTS: The measurements were conducted before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in the pain intensity (p<.05), ODI (p<.05), and SF-36 (p<.05) at the end of the intervention. No significant differences in the Barthel Index were found between the two groups. CONCLUSION: These findings show that an IFC treatment can improve pain, functional ability, and quality of life, highlighting the benefits of somatosensory stimulation from IFC in stroke patients with lumbago.

PURPOSE: The purpose of this study is to examine the impact of balance training on a three-dimensional balance trainer that provides the up-and-down vertical movement of the knee joint and left-and-right horizontal movement, along with visual feedback on the functional ability of children with spastic cerebral palsy (CPs). METHODS: 8 CPs participated in this study. The experiment was implemented for 40 minutes, three times a week for a total of six weeks. The subjects received general physiotherapy for 15 minutes in each session focused on balance and walking, as based on the neuro-developmental treatment theory. Balance training was performed for 20 minutes on a three-dimensional balance trainer where knee joint movement providing visual feedback is applied. The evaluations were conducted before and after the test, and posture sway was measured using 10 Meter Walking Test (10MWT), Timed Up & Go Test (TUG), and the Good Balance System to evaluate the functional ability and balance of the subjects RESULTS: 10MWT was not statistically significant (p>.05). On the contrary, TUG and postural sway indicate static balance showed a statistically significant decrease (p<.05). In a static balance test using the Good Balance System, the average moving speed statistically significantly decreased in the AP and ML directions (p<.05), and the mean velocity moment also significantly decreased (p<.05). CONCLUSION: These findings suggested that balance training using the three-dimensional balance trainer, with the features of visual feedback and up-and-down knee joint movement effects on increasing dynamic and static balance.

This study examined the effects of biofeedback postural control training on the weight distribution rate and functional ability of subjects with stroke. A total of 30 stroke patients were enrolled in this study. Subjects were divided into a biofeedback postural training group (experimental group, n=15) and a dynamic balance training group (control group, n=15). Experimental subjects received biofeedback postural training and control subjects received dynamic balance training for 30 minutes per day, 5 times per week over a 6 week period. Weight distribution rate and functional ability were measured to identify the effect of the biofeedback postural training. Significant difference in weight distribution rate was observed in the experimental group, compared with the control group (p=0.05), and a significant difference in functional ability. The results of this study provide evidence in support of incorporating a biofeedback postural training for the improvement of weight distribution rate and functional ability of stroke patients.

Objective To systematically translate the Duchenne muscular dystrophy Functional Ability Self-Assessment Tool (DMDSAT) into Korean and verify the reliability and validity of the Korean version (K-DMDSAT). Methods The original DMDSAT was translated into Korean by two translators and two pediatric physiatrists. A total of 88 patients with genetically confirmed Duchenne muscular dystrophy (DMD) participated in the study. They were evaluated using the K-DMDSAT once as a self-assessment and once by an interviewer. The interviewer evaluated the K-DMDSAT again 1 week later using a test-retest approach. The intraclass correlation coefficient (ICC) was used to verify the interrater and test-retest reliabilities. Pearson correlation analysis between the K-DMDSAT and the Brooke or Vignos scales were used to assess validity. Results The total score and all domains of the K-DMDSAT showed excellent interrater and test-retest reliability, with an ICC for total scores of 0.985 and 0.987, respectively. All domains had an ICC >0.90. From the Pearson correlation analysis, the total K-DMDSAT score was significantly correlated with the Vignos and Brooke scales (r=0.918 and 0.825, respectively; p<0.001), and each domain of K-DMDSAT showed significant correlation with either the Vignos or Brooke scales. Conclusion DMDSAT was systematically translated into Korean, and K-DMDSAT was verified to have excellent reliability and validity. K-DMDSAT can help clinicians easily describe and categorize various functional aspects of patients with DMD through the entire disease progression.

Background: In patients with lumbar spinal stenosis (LSS), lumbar flexion exercise (LFE) is considered a standard therapeutic exercise that widens the space between the spinal canal and intervertebral foramen. However, some researchers have reported that lumbar extension exercise (LEE) may improve lumbar pain and functional ability in patients with LSS. Although exercise intervention methods for patients with LSS have been widely applied in clinical settings, few studies have conducted comparative analysis of these exercise methods. Objects: This study aimed to compare the effects of LFE, LEE, and lumbar flexion combined with lumbar flexion-extension exercise (LFEE) on pain, range of motion (ROM), pelvic tilt angle, and functional gait ability in patients with LSS. Methods: A total of 30 patients with LSS, LFE (n1=10), LEE (n2=10), and LFEE (n3=10) were assigned to each of the three exercise groups. The numerical pain rating scale (NPRS), modified-modified schober test (MMST)-flexion, MMST-extension, pelvic tilt inclinometer, and 6-minute walking test (6MWT) were measured. Results: After the intervention, statistically significant differences were observed in the NPRS (p=.043), MMST-flexion (p<.001), MMST-extension (p<.001), and 6MWT (p=.005) between groups. According to the post hoc test, the NPRS was statistically significant difference between the LFEE and LEE groups (p=.034). The MMST-flexion was statistically significantly different between the LFE and LEE (p=.000), LFE and LFEE (p=.001), and LEE and LFEE (p=.001) groups. The MMST-extension was statistically significantly different between the LFE and LEE (p<.001), LFE and LFEE (p=.002), and LEE and LFEE (p=.008) groups. The 6MWT was statistically significantly different between the LFE and LFEE (p=.042) and the LEE and LFEE (p=.004) groups. Conclusion: This study suggested that LFEE was the most effective exercise for pain and functional gait ability in patients with LSS, LFE was the most effective exercise for lumbar flexion ROM, and LEE was the most effective exercise for lumbar extension ROM.

Purpose: This study examined the effects of stretching and strengthening exercises on the pain, pelvic tilt (PT), functional disability, and balance of patients with chronic lower back pain (CLBP). Methods: A total of 42 patients with CLBP were randomly divided randomly into either experimental group I (EG I, n=21), who received stretching exercise, or experimental group II (EG II, n=21), who received strengthening exercise. Both interventions were applied three times a week for eight weeks. Assessments were made with a visual analogue scale (VAS), PT, Oswestry disability index (ODI), and Berg's balance scale (BBS) before and after the eight weeks intervention period. A paired t-test was conducted to compare the within-group changes before and after the intervention. An independent t-test was used compare the between-group difference. The statistical significance level was set to ${\alpha}=0.05$ for all variables. Results: The EG I and II showed significant within-group changes in the VAS, PT, ODI, and BBS (p<0.05). The changes in VAS, PT, ODI, and BBS were similar regardless of the exercise form. Conclusion: In this study, the application of stretching and strengthening exercise for subjects who complain of CLBP was effective in changing the level of pain, PT, functional disability, and balance.

Purpose: This study examined the effects of heel raise exercises combined with neuromuscular electrical stimulation (NMES) on the muscle strength and postural control ability of subjects with functional ankle instability (FAI). Methods: Twenty-two subjects with FAI participated in this study. They were assigned randomly to two groups: 11 each in the NMES and the sham-NMES groups. Heel raise exercise was applied, and NMES electrodes were attached to the peroneus longus muscles. The NMES group applied NMES during the heel raise exercise. NMES was applied for 20 minutes during the heel raise exercise. The heel raise exercise was performed four times a week for five weeks. The muscle strength and balance error scoring system (BESS) were measured before and after the intervention. Results: A comparison of before and after the intervention within the groups revealed improved muscle strength in the NMES and Sham-NMES groups, but the BESS was improved under all conditions only in the NMES group. The Sham-NMES group showed no improvement in the unstable support surface. Furthermore, when comparing the amount of change before and after the intervention between the groups, there were significant differences in the total score and unstable support in the BESS and muscle strength. Conclusion: NMES had a positive effect on the functional activities of the functional ankle instability subjects, such as balancing on an unstable support surface during postural control and increasing muscle strength.

The present study was aimed at investigating the postural control ability of volleyball players with functional ankle instability. The subjects were 26 male volleyball players were divided into 2 groups (13 subjects with functional ankle instability and 13 subjects with ankle stability) who could evaluate Questionnaire. All the male participants were tested by a Balance Master System. This study were to measure of static balance ability, dynamic balance ability, motor function the difference between functional ankle instability group and control group. Ankle instability group and stable group in postural sway ($^{\circ}/sec$) on film surface with eye closed in modified clinical test sensory interaction on balance, and left unilateral stance with eye opened and closed were significantly different (p<.05). The ankle instability group and stable group in limit of stability were significantly different (p<.05). The ankle instability group and stable group in left/right rhythmic weight shirt were significantly different (p<.05). The ankle instability group and stable group in turn time (sec) & turn sway ($^{\circ}$) during step/quick turn and end sway ($^{\circ}/sec$) in tandem walk were significantly different (p<.05). This study showed that volleyball players with functional ankle in stability were effected postural control ability by static balance & dynamic balance ability. Further study is needed to measure various athletic with functional ankle instability for clinical application.

Objective: The aim of this research was to investigate the effects of functional electrical stimulation (FES) applied to the gluteus medius (Gm) and tibialis anterior (TA) during stair climbing in persons with stroke compared to FES applied to the TA only during stair climbing, and during stair climbing without FES in persons with stroke. Design: Cross-sectional study. Methods: Twenty subjects with stroke participated in this study. Subjects were included if: 1) they were diagnosed as stroke at least 6 months before; 2) had Mini Mental State Examination- Korean score of 24 or higher; 3) were able to climb a flight of 10 stairs independently (with or without walking aid). The patients walked 10 stairs 3 times with FES applied to the Gm and TA, only TA, or no FES. There was a 1-minute rest period between each bout. The assessments were made using the Timed Up & Down Test and the Wii Balance Board. Results: Stair climbing with FES applied to the Gm and TA was significantly faster than stair climbing with FES applied to the TA only and without FES (p<0.05). Stair climbing with FES applied to the Gm and TA exhibited significantly greater sway velocity than stair climbing without FES (p<0.05). However, maximal sway distances were not significantly different between groups. Conclusions: Stair climbing with FES applied to the Gm and TA can be an important component of a rehabilitation program for improving stair climbing ability in persons with stroke.

Purpose: This study focuses on influence of ankle stabilization training on balance ability and lower limb muscle activation of soccer player with functional ankle instability. Methods: Subjects were grouped into ankle stabilization training group using biofeedback comprised of 15 subjects and general exercise group of 15. The training was conducted for 30 minutes, 3 times a week for 8 weeks in total. All 30 football players conducted plyometric training for 30 minutes before main training. To evaluate balance ability, biorescure was used to measure whole path length and surface area and surface electromyography (EMG) system was used to measure tibialis anterior, tibialis posterior, and soleus to evaluate lower limb muscle activation. Results: The experiment group showed significant difference to the comparison group in regard of whole path length and surface area which represents balancing capability and muscle activation of tibialis anterior, tibialis posterior, and soleus. Conclusion: Therefore, ankle stabilization training using biofeedback is more effective in enhancing balance ability and lower limb muscle activation than general exercise.

The purpose of this study was to exam 12 weeks of stair and normal walking effects on lower extremity functional ability and cardiovascular health risk factors in older women. Twenty four subjects were assigned to either stair walking group (SWG, 57.40±6.11yrs, n=10) or normal walking group (NWG, 57.28±16.83 yrs, n=14). They performed 3 times per week, 60 minutes per day for 12 weeks. Lower extremity functional ability (lower leg strength, walking speed, balance ability, agility) and cardiovascular health risk factors (body composition, waist circumference, blood lipids) were compared by time and groups by two-way repeated ANOVA. As results, Significant time differences were found in lower muscular strength (sit & stand, wall squat), active balance and no time & group interaction were found. Also, significant time differences were found in SBP, T-C, TG, fasting glucose and no time & group interaction were found. These results indicated that home-based stair and normal walking exercise can be utilized to improve lower extremity function ability and cardiovascular health risk factors in older women. These findings implies that performing stair walking exercise provide similar positive health benefits with normal walking. Also, even when walking exercise perform independently as home-based program without instructor, health benefit can still be expected.
