PURPOSE: The purpose of this investigation was to conduct a systemic review of studies that examine the effects of strengthening exercise on gait ability and GMFM in children with cerebral palsy and propose a standard for cerebral palsy therapy based on a meta-analysis of the studies. METHODS: An extensive literature search was conducted using databases including the KISS (Korean studies Information Service System), RISS, DBpia, PubMed and ScienceDirect, with the following search terms: 'Strengthening Exercise,' 'Resistance Exercise,' 'Gait ability,' 'GMFM' or 'cerebral palsy'. RESULTS: Eleven studies were included in this review and the duration of the intervention varied from 5 to 24 weeks. The number of application per week was mostly 2-3 times, while 5 intervention per week was adopted in a few cases. The total number of intervention applied varied from 18 to 36 and the respective effect sizes of GMFM on crawling and sitting were very high (1.075 and .881) while those of GMFM on standing and walking were very low(.206 and .125). The effect size was for gait speed was only .221. CONCLUSION: Trunk exercise and lower limb exercise effectively improved GMFM in children with cerebral palsy, resulting in improved outcomes in sitting and crawling. The results of this study will be useful for designing evidencebased cerebral palsy therapy programs.

Purpose: This study examined the effects of a shoulder-strengthening exercise on muscle strength of shoulder flexors and extensors of caregivers. Methods: The study consisted of 19 caregivers (2 males and 17 females) employed by Medical Center B. All the participants took part in an 8-week shoulder muscle strengthening exercise, based on previous studies. In the first week, the subjects took part in a stretching exercise enhance the range of motion. In the second week, they participated in an exercise aimed at improving shoulder blade stability. From the third to seventh weeks, a resistance exercise of different intensities was applied in a phased manner. Finally, in the eight week, the subjects took part in plyometric exercise. Peak torque, average power, and total work of shoulder flexors and extensors in both sides were measured before and after the exercise at an angular speed of 120deg/sec using an isokinetic device. Wilcoxon's singed-ranks test was conducted to analyze differences in muscle strength before and after the intervention. Results: After the exercise, there was a significant improvement in peak torque and average power of flexors of the right arm. After the exercise, peak torque, total work, and average power showed a significant improvement in the flexors of the left arm (p<0.05). However, there was no statistically significant difference in extensor muscle strength in either arm after the exercise. Conclusion: Shoulder flexors of caregivers are utilized frequently in the workplace. Implementation of extensor-strengthening exercises, in addition to flexor-strengthening exercises, can contribute to reducing the incidence rate of shoulder injuries among caregivers.

Purpose: The purpose of study was to test the effect of lower extremity muscle strengthening exercise using elastic resistance on balance on elderly women. Methods: Twenty four women who were over 65 years old were randomly assigned to either the experimental group that received the exercise programme (n=12) or to the control group (n=12) that continued normal activities except programme. Exercises included the following 7 different activities; chair squat, knee flection, extension, hip flection, extension, calf muscle raise, ankle dorsiflection. All the participants were subject to 3 tests, including One-Leg Standing Test, Functional Reaching Test, and Up & Go Test. The measurements were made before the excercise, 4 and 8 weeks after the exercise. The data were analyzed by using the two way repeated ANOVA. Results: The results were as follows; As compared with change of balance capacity between groups, a significant difference was shown in the up and go test (p<.05), but not in balance performance clinical test of OLST (p>.05) and FRT (p>.05). Conclusion: The lower extremity muscle strengthening exercise using elastic resistance for the elderly women had some positive effects on the balance. Therefore this intervention can be broadly applied to other elders for preventing falls.

PURPOSE: The purpose of this study was to apply dynamic neuromuscular stabilization (DNS) to subjects with forward head posture (FHP) and to compare its effects on respiratory function as against the conventional neck stabilization exercise and neck stretching and extensor strengthening exercises. METHODS: The whole-body posture measurement system was used to measure the degree of FHP, and a spirometer and a respiratory gas analyzer were used to measure the respiratory function. After the intervention was completed, the changes over time were analyzed in the DNS group, the neck stabilization exercise group, and the neck stretching and extensor strengthening exercise group. The inter-group difference in the changes was also analyzed. A repeated ANOVA was performed to compare the respiratory function according to the period between the three groups, and the least significant difference (LSD) method was used for the post hoc test. RESULTS: After the 6-week exercise period, respiratory functions, such as forced vital capacity (FVC), forced expiratory volume for 1 second (FEV1), forced expiratory volume for 1 sec/forced vital capacity (FEV1/FVC), maximum oxygen intake (VO₂max), and the volume of expired gas (VE), significantly improved according to the period (p < .05), but no inter-group differences were found. CONCLUSION: DNS is an effective training method, and can be applied along with neck stabilization exercise and neck stretching and extensor strengthening exercises, which are widely used in clinical practice, to people with FHP who cannot directly perform neck exercises to improve their respiratory function.

Purpose: This study was conducted to verify the effect of applying a pressure biofeedback unit on walking ability and knee joint function while performing knee joint extensor strengthening exercises using resistance exercise equipment in total knee replacement (TKR) patients. Methods: This study was conducted on twelve patients receiving rehabilitation treatment after being admitted to a rehabilitation hospital post-TKR. Of these, six were allocated to a feedback group with a pressure biofeedback unit, and the other 6 were allocated to a control group without a pressure biofeedback unit. The subjects performed an exercise program for 45 minutes per session, five times a week, for two weeks. Walking ability and knee joint function were evaluated and analyzed before and after exercise. Results: The feedback group showed significantly better improvements in walking speed, gait cycle, step length on the non-operation side, time on the foot on the operation side, K-WOMAC stiffness, and K-WOMAC function than the control group (p<0.05). Conclusion: When strengthening the knee joint extensor muscles using resistance exercise equipment in TKR patients, the provision of a pressure biofeedback unit was found to improve walking ability and knee joint function by inducing concentric-eccentric contraction of the knee joint extensor muscles. Therefore, the study shows that exercise based on the provision of a pressure biofeedback unit should be considered when strengthening knee joint extensor muscles to improve the walking ability and knee joint function of TKR patients in clinical practice.
