Purpose : The purpose of this study was to identify the comparison of the effects of manual therapy combined with exercise on range of motion (ROM), muscle strength, and functional performance in adolescent baseball players with internal impingement syndrome of the shoulder. Methods : The subjects were 30 patients diagnosed with impingement syndrome of the shoulder. Thirty subjects are randomly assigned to each 3 different groups; Group 1. (exercise group), Group 2. (exercise+mobilization; EMOB group), Group 3. (exercise+mobilization with movement; EMWM group). The interventions were performed three times a week for 4 weeks. The main outcome measures were goniometer, Biodex dynamometer, and Korean Kerlan Jobe shoulder-elbow (K-KJOC) scores. The ROM (external and internal rotation), muscle strength (external and internal rotation: 60 °/sec., 180 °/sec.), and functional performance were compared among the groups. Results : No significant difference was observed among the groups in the range of external rotation of the shoulder before and after the intervention, but the range of internal and total rotation was significantly increased in Group 2, 3 compared to Groups 1. Muscle strength of external and internal rotation (60 °/sec., 180 °/sec.) was not significantly different among Group 1, 2, 3, and functional performance was significantly increased in Group 2, 3 compared to Group 1. However, there was no significant difference between Group 2 and Group 3 in all measurements. Conclusion : An intervention with manual therapy such as EMOB and EMWM was more effective than exercise alone for rapid recovery from shoulder injury and improvement in functional performance. However, further efforts are needed to identify effects of specific interventions with manual therapy.

The purpose of this study was to investigate the effect of Forest-walking exercise on gait pattern in the elderly. The subjects (n=37) were assigned to 2 groups: Forest-walking exercise (FWE) group (n=19, $66.34{\pm}4.31$ years old) and In-door treadmill-walking exercise (ITWE) group (n=18, $67.18{\pm}2.78$ years old). The subjects participated in FWE program or ITWE program (3 times/week, 80 min/day) for 12 weeks. The subjects were tested on functional fitness (strength, endurance, agility/balance, BMI) and gait pattern (cadence, velocity, and stability) at the beginning and the end of the 12-weeks program. For data analysis, mean and standard deviation scores were calculated, and independent t-test and repeated two-way ANOVA were used. The results of this study were as follow: First, FWE group was significantly more improved than ITWE group on functional fitness(lower-body muscular strength, lower-body flexibility, mobility, cardiorespiratory endurance) after 12-weeks exercise program. But both groups showed equally improvements on functional fitness (upper-body muscular strength, upper-body flexibility, BMI). Second, FWE group was significantly more improved than ITWE group on cadence, gait velocity, and gait stability after 12-weeks exercise program. Therefore, this study may suggest that Forest-walking exercise based on sensory-motor functional integration improves efficiently functional fitness and gait pattern in the elderly, and further becomes an effective exercise method that makes more dynamic life, and prevents from falling.

Muscle weakness in the hemiplegia following stroke is an important factor which determines the quality of life in the future. Therefore, muscle strengthening exercise is essential for functional recovery in hemiplegic patients. Even though the popular conception is that muscle strengthening exercise causes spasticity and associated reaction that hemiplegia patients don't want, and that it disturbs functional recovery, recently there have been many new reports against that opinion. Therefore, the effects of strengthening exercise programs on functional recovery in hemiplegic patients are still controversial. The purpose of this study was to determine the effects of strengthening exercise programs for the knee joint using isokinetic exercise on the associated reaction of the upper extremities. Comparing the muscle activities of biceps brachii and triceps brachii during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise, we examined the increase and decrease of associated reaction. Twenty stroke inpatients participated in this study. Surface electromyography was used to get muscle activity data from biceps brachii and triceps brachii. The major findings of this study were as follows: 1. The flexor and extensor peak torque were significantly higher on the sound side than the affected side (p<.05). 2. Before and after strengthening exercise, there was no significant difference in muscle activities (surface electromyographic root mean square values) between the sound and affected side. 3. Muscle activities were examined during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise. There were significant differences in muscle activities between, before and during the exercises, during exercise and 5 minutes after exercise in the biceps brachii (p<.05), and during exercise and 5 minutes after exercise in the triceps brachii (p<.05). In conclusion, there was no relation between strengthening exercise and associated reaction in the upper extremities. Rather, muscle activities after exercise had a tendency to decrease relative to before the exercise. Thus, it is considered that intensive strengthening exercise contributes to improvement of functional recovery without increase in associated reaction in hemiparetic patients.

The purpose of this study was to investigate the complex ankle exercises on balance. 22 participants (male: 14, female: 8) with functional ankle instability were participated. Functional ankle instability was selected to be less than 24 points using the Cumberland ankle instability tool (CAIT) with people who had severe ankle sprain and then experiencing ankle giving way. A total of 20 minutes performed three times a week for four weeks with muscle strength and balance exercises. Muscle strengthening exercise was performed with Theraband, and balance exercise was performed with unstable support plates. Biodex balance system(R) was used to measure static and dynamic balance. The dynamic balance was selected in grade 2, 4, and 8. The static and dynamic balance (grade: 2, 4,and 8) balance was significantly decreased in anterior-posterior, and medial-lateral directions (p<.05). The instability was significantly increased after exercise (p<.05). These results suggest that complex exercises are beneficial to decreasing the functional ankle instability.

This study aimed to evaluate the effect of a weekly circuit-group exercise program on functional performance, flexibility of the trunk and lower extremities, and balance in individuals with chronic stroke who are living in a community. Thirteen community-living individuals (eleven males and two females) with chronic stroke participated in this study. The group exercise program was set up as a weekly circuit application with four stations aiming to strengthen the muscles, increase endurance, improve flexibility, and enhance functional capacity. The average duration of a session was an hour, and the sessions were conducted once a week for six months for a total of 24 sessions. Assessments for functional performance, flexibility of the trunk and lower extremities and balance were conducted four times: before treatment, after one month of treatment, after four months of treatment, and after six months of treatment. There were significant improvements in functional performance and flexibility of the trunk and lower extremities in the given time frame. No significant improvement was observed in balance ability. The findings suggest that a weekly circuit-group exercise program has some benefits in terms of managing the physical symptoms of individuals with mobility problems after stroke. Therefore, this program can be adapted and employed as a community-based rehabilitation program for such patients. Further studies with various community-based treatments will be conducted to validate these findings.
