The purpose of this study was to examine the effects of thoracic flexibility exercise on sitting balance, static standing balance, gait parameters, and the fall risk of patients with chronic stroke. The participants were randomized into the control (n=12) and thoracic flexibility exercise groups (n=12). Both groups received standard rehabilitation therapy for 30 minutes per session. The subjects in the experimental group performed additional thoracic flexibility exercises 3 times a week for 6 weeks. The trunk impairment scale, static standing balance, gait speed, cadence, and fall risk were assessed for all the participants before and after the intervention. The thoracic flexibility exercise group showed greater improvement than did the control group on the trunk impairment scale (t=-3.57, p=.002), static standing balance (t=5.37, p<.001), gait speed (t=-3.29, p=.003), cadence (t=-2.77, p=.011), and fall risk (t=6.33, p<.001). Furthermore, the thoracic flexibility exercise group significantly improved all the outcomes compared to the baseline values (P<.05). This study showed that the thoracic flexibility exercise improved the functional ability of patients with chronic stroke.
Background: The purpose of this study is to measure the amount of influence of taping and a whole body balance upon muscle strength, endurance, and flexibility. Experiments were conducted by two different groups, specially designed for this study. The choice of exercise methods for each group depends on its own idiosyncratic characteristics (or Each group employs its own idiosyncratic exercise method). Methods: The first group, with taping applied, undertook exercises three times a week; second group just took exercises three times a week. These experiments show the following outcomes. Results: The first group showed a considerable amount of difference in terms of muscle strength, endurance, and flexibility. Second group also showed similar outcome. Both the first group and the second group revealed a considerable difference. But the first group showed a bigger difference than the second group. Conclusion: Thus, the result of these experiments strongly indicates that exercise, with taping applied, turns out the most effective in promoting muscle strength, endurance, and flexibility.
Squats and lunges are important exercises for strengthening the trunk and lower body among various free weight exercises. It should be achieved safe and effective excise through establishing of theoretical basis for exercise posture and standard movement. Therefore, it's necessary to develop the exercise model in order to prepare the scientific countermeasures for the prevent injuries and error movement through optimal exercise movement. For this purpose, it is effective to use appropriate instruments for motion compensation according to the optical motion and error motion. In this paper, we develop a motion model analysis system based on dynamic motion through the four-point load cell for dynamic motion analysis. Proposed analytical method, the optimal and the error motion numerical data is obtained through the dynamic motion analysis. And we verified that dynamic movement is simplified to establish the motion modeling according to the classification motion and the numerical quantification data for analyzing.

The main purpose of this thesis was to provide a basis to investigate the effectiveness of regular exercises on basic physical fitness for middle school students. 40 second graders from a middle school were chosen randomly and divided into 4 groups-wrestling group, basketball group, jogging group, and control group. The first three groups have been trained 4 times per week for 18 weeks after class to be compared with the comparison group. Pre and post measurements of physical fitness of the subjects were processed by means of the SPSS program. The average and the standard deviation of the measurements of each group were covered with the ANOVA test, according to the periods and the types of training. Duncan's Multiple Range Test was performed to identify the significance of the relationship between training period and improvement in basic sports ability. The conclusions as follows; 1. In the 50 meter sprint, only the wrestling group showed statistical significance, while the other groups showed gradual progress in general. 2. In the standing long jump, there is no group that showed any improvement. 3. In the forward flexion of the trunk, no significance was to be found. 4. In 30-second sit-ups, the wrestling group showed statistical significance. The wrestling group made greater progress than the other groups, and the basketball group and the jogging group also showed rather great progress. 5. In push-ups, statistical significance was found in the groups of wrestling, basketball, and jogging. And the wrestling group came in first, the basketball group second, and the jogging group third on the progress level. 6. In the distance run, the jogging group showed statistical significance and the jogging group made considerable progress. Steady improvement was to be found in the groups of wrestling and basketball.
Objective: This study aimed to identify the effects of assuming different knee angles and hip abduction during bridge exercise and hip thrust exercise on lower body muscle activity. Design: Cross-sectional study Methods: Thirty-three healthy adults (18 men and 15 women) were instructed to perform the bridge and hip thrust exercises while randomly assuming 120°, 90° and 60° of knee flexion and 0° and 30° of hip abduction. EMG data (%maximum voluntary isometric contraction) were recorded three times from the erector spinae (ES), gluteus maximus (GM) and biceps femoris (BF) muscles of participant's dominant side and the mean values were analyzed. Results: The results showed that, during the hip thrust compared to the bridge exercise, there was significantly greater gluteus maximus muscle activity in all hip conditions while the biceps femoris activity was significantly less, and the erector spinae muscle activity was significantly greater with 30° of hip abduction (p<0.05). With all exercises, the erector spinae and the biceps femoris exhibited significantly greater muscle activity with 60° of knee flexion compared to 90° and 120° of knee flexion (p<0.05), and significantly greater muscle activity with 90° compared to 120° of knee flexion (p<0.05). In the case of the gluteus maximus, greater muscle activity was exhibited with 120° compared to 60° of knee flexion with all hip abduction conditions (p<0.05). Conclusions: It was effective for muscle activation of main agonists such as the gluteus maximus and erector spinae during thrust exercise, and the change in knee flexion angle was effective for muscle activation of the gluteus maximus. Therefore, it is considered that this study can be used as a selective indicator of the target movement angle during hip strengthening exercise for specific muscles.

Background: The understanding of back-pain as one of the commonest clinical presentations, made the path to the present study. More than three-quarters of the world's population experience back-pain at some time in their lives Purpose: The present study has evaluated the selected Naturopathic therapeutic procedures on individuals with low back-pain. Methods: Thirteen patients were selected for the study and randomly divided into two groups, viz., Group A, Naturopathic group and Group B, Control group. One patient discontinued. Naturopathic group was treated with mud pack, aromatherapy massage with Eucalyptus oil, acupressure, steam, wet trunk pack, exercises, relaxation and breathing exercises. Advice for life style and diet was given for patients of both the groups. The effect of the therapy was assessed subjectively and objectively. Particular scores drawn for Naturopathic group and control group were individually analyzed before and after treatment and the values were compared using standard statistical protocols. Results: Naturopathic intervention revealed 100% relief in both subjective and objective parameters (i.e., 6 out of 14 parameters showed statistically highly significant P < 0.01 results, while 8 showed significant results P < 0.05). Conclusion: Statistically highly significant results of this study point out the successful management of the multi factorial low back-pain with a multi focused Naturopathic treatment approach. Such encouraging results may pave the way for a future study on a large sample in a longer duration incorporating clinical investigations.

PURPOSE: The purpose of this study was to investigate the effects of a group exercise program with competitive games on balance in chronic stroke patients. METHODS: The subjects were chronic stroke patients living at home after their discharge from the hospital. A total of 32 subjects were divided into two groups. The experimental group performed a group exercise program with competitive games, and the control group performed individual exercises. The exercise program duration was one hour, and it comprised 10 minutes of stretching, 40 minutes of the main exercise, and 10 minutes of stretching at the end. The experimental group was divided into two teams of 8 players each and played competitive games (transfer a gym ball to another person, relay 10 m walking and return, transfer an object to the next person using both arms while sitting). The control group performed an arm/trunk exercise for 15 minutes and gait training for 25 minutes. These exercises were conducted twice a week (4 weeks). The Berg Balance Scale (BBS) and timed up-and-go (TUG) tests were performed to confirm the change in balance. RESULTS: In the experimental group, BBS showed a significant increase (p < .05) and TUG showed a significant decrease (p < .05). In the control group, there was no statistically significant change in the BBS. However, the TUG showed a significant decrease (p < .05). The BBS and TUG both showed statistically significant differences (p < .05) in the between-group comparison of the change in pre-post intervention values. CONCLUSION: A group exercise program with competitive games to improve the balance ability for fall prevention in chronic stroke patients could be used as a good intervention method.
Background: Low back and neck pain are two of the most common medical problems in the adult population. It is estimated that between 70% and 80% adults experience an episode of low back pain at least once during their lifetime. Objects: This study aimed to compare the effects of various stretching exercises and muscle energy techniques used for treatment of iliopsoas, quadratus lumborum, and hamstrings of patients with low back pain. Methods: A total of 52 subjects were randomly assigned to the control group (n = 17), the muscle energy technology group (METG, n = 19), and the stretching exercise group (SEG, n = 16). Interventions were performed twice a week for 4 weeks. Outcomes were measured before and after 4 weeks of treatment in the three groups, using the Korean version of the Oswestry Disability Index, the Visual Analogue Scale (VAS), the Fear Avoidance Belief Questionnaire (FABQ), the Finger to Floor test (FTF), the Modified-Modified Schober Test (MMS), and the Trunk Flexion Range of Motion test. Results: This study showed significant reduction in the pre-test and post-test KODI, VAS, and FABQ scores in all the three groups (p < 0.05). The KODI, VAS, FABQ and FTF assessed in this study showed interactions between the groups and the measurement time point (p < 0.01). After intervention, the KODI, VAS, FABQ and FTF in the SEG and METG were significantly higher (p < 0.05), and there was no difference between the METG and SEG. MMS and HFROM test showed no difference between the three groups (p > 0.05). Conclusion: KODI, VAS, FABQ and FTF showed significant improvement after basic physical therapy, muscle energy technique, and stretching exercise intervention. And there was no significant difference in the intervention effect between the muscle energy group and the stretching exercise group.
This study was designed to determine the effects of different widths in the base of support (BOS) on trunk and lower extremity muscle activation during upper extremity exercise. Twenty-seven healthy male subjects volunteered for this study. Exercises were performed for a total of 10 trials with a load of 10 repetitions maximum (10 RM) for each of the various widths of BOS (10 cm, 32 cm, 45 cm). The width of a BOS is the distance between each medial malleoli when a subject was in a comfortable standing position. Electromyography was used to determine muscle activation. Surface bipolar electrodes were applied over the tibialis anterior, medial gastrocnemius, biceps femoris, rectus femoris, gluteus maximus, upper rectus abdominis, and elector spinae muscle. Electromyographic (EMG) root mean square (RMS) signal intensity was normalized to 5 seconds of EMG obtained with a maximal voluntary isometric contraction (MVIC). The data were analyzed by atwo-factor analysis of variance (ANOVA) with repeated-measures ($3{\times}7$) and Bonferroni post hoc test. The results were as follows: (1) There were significant differences in the width of the BOS (p=.006). (2) The post hoc test showed significant differences with the BOS between 10 cm and 32 cm, between 10 cm and 45 cm and between 32 cm and 35 cm (p=.008, p=.003, p=.011). (3) There was no interaction with the BOS and muscle. (p=.438) There were no significant differences in the muscle activation (p=.215).
