PURPOSE: This study aimed to provide basic clinical data by analyzing the impact of motion observation training and stretching exercises for improving postures on the neck alignment and balance of stroke patients to enable them to accurately recognize the correct exercise method. METHODS: After sampling 20 stroke patients who met the selection criteria, this study randomly assigned 10 people who were administered the stretching exercise with observation training to the experimental group and 10 who received only the stretching exercise intervention to the control group by drawing lots. Next, neck alignment and balance were pre-tested. All interventions were conducted for 30 minutes, 3 times a week for 4 weeks, and when all the interventions were completed after 4 weeks, neck alignment and balance were re-measured in the same way as the pre-test. RESULTS: The comparison of changes in neck alignment and balance within the experimental and control groups showed statistically significant differences in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). Between the groups, statistically significant differences were found in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). CONCLUSION: A statistically significant difference in neck alignment and balance was observed in the group that underwent stretching exercises combined with observational training and a statistically significant difference was found between the groups. Therefore, it is believed that observation training should be used in clinical practice to improve forward head posture and restore balance in stroke patients.

PURPOSE: The purpose of this study was to investigate the effects of passive stretching exercises of the scalene muscles known as respiratory accessory muscles, on forced vital capacity. METHODS: Ten of the participants were randomly selected as an experiment group to perform passive stretching exercises on the scalene muscles. Ten additional students were selected randomly as a control group. The forced vital capacity was assessed by using a digital spirometer (Pony FX, COSMED Inc, Italy) both before and after the passive stretching exercises were performed. Subsequently, passive stretching exercises of the scalene muscles were performed in the experimental group. There were no interventions to the control group. RESULTS: As for the forced vital capacity (FVC), the experiment group showed significant increase in items of forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), peak expiratory flow (PEF), forced expiratory volume in 1 second/vital capacity ($FEV_1/VC$), and maximal expiratory flow 75%(MEF 75%) after the scalenemuscles passive stretching exercises were performed. The control group, however, showed no change. CONCLUSION: This study demonstrated that passive stretching exercises of the scalene muscles could be helpful for forced vital capacity improvement.

Purpose: This study was conducted in order to investigate the effectiveness of an 8-week virtual reality exercise program designed around the Nintendo Wii (Wii), in improving balance among patients with Multiple Sclerosis (MS). Methods: The study included 16 patients with MS (10 female, 6 male) who were assigned randomly to experimental (n=8) or control group (n=8). Experimental group performed three 40-minute Wii balance-training sessions per week, for 8 weeks. The control group did not perform any of the training programs. A computerized dynamic posturography (Sensory Organizing Test, SOT) was used to evaluate all patients at baseline and at the end of the treatment protocol. Statistical significance was tested in between the patients before and after treatment by t-test. Results: After 24 training sessions, SOT showed significant difference on condition 5, 6, and vestibular ratios within the experimental group from baseline to post-intervention. By contrast, no significant difference was observed within the control groups. Conclusion: These findings demonstrated that the virtual reality training program could improve the outcomes in terms of balance in the MS population. Long term follow ups and the development of more efficient virtual reality training programs are needed.

It is important to consider lumbar lordotic angle for setup of training program in field of sports and rehabilitaton to prevent unexpected posture deviation and back pain. The purpose of this study was to analyze the biomechanical impact of the level of lumbar lordosis angle during isokinetic exercise through dynamic analysis using a 3-dimensional musculoskeletal model. We made each models for normal lordosis, excessive lordosis, lumbar kyphosis, and hypo-lordosis according to lordotic angle and inputted experimental data as initial values to perform inverse dynamic analysis. Comparing the joint torques, the largest torque of excessive lordosis was 16.6% larger and lumbar kyphosis was 11.7% less than normal lordosis. There existed no significant difference in the compressive intervertebral forces of each lumbar joint (p>0.05), but statistically significant difference in the anterioposterior shear force (p<0.05). For system energy lumbar kyphosis required the least and most energy during flexion and extension respectively. Therefore during the rehabilitation process, more efficient training will be possible by taking into consideration not simply weight and height but biomechanical effects on the skeletal muscle system according to lumbar lordosis angles.

Background: The purpose of this study was to investigate the effects of ipsilateral and contralateral load changes during single-leg standing on the leg muscle activities of healthy people. Design: Randomized controlled trial. Methods: For all the subjects, a load was randomly applied to the ipsilateral or the contralateral side. While the load was applied, the subject raised a hand and then performed single-leg standing for 10 seconds using the dominant side. Results: During single-leg standing, the muscle activity of the gluteus medius, peroneus longus on the supporting side increased statistically significantly when an upper limb load was applied contralaterally, but no statistically significant differences were detected in the muscle activities of the tibialis anterior and the gastrocnemius using a test of within-subjects effects. Conclusion: It can be seen that muscle activities increase during exercise when the amount and frequency of a load are increased and when the same load is applied to different sides of the body. Such muscle activity increases may be applied to change the intensity of exercise when one is in a static posture, such as during single-leg standing.

Purpose : The purpose of present study is to evaluate the joint angles of legs in the standing posture for six patients with unilateral knee osteoarthritis. Methods : The participants underwent unilateral total knee replacement. A motion analysis was used to measure the joint angles of the hip, knee, and ankle. The measurements were taken before the surgery, one week and two weeks after the surgery. Both sides of the legs were evaluated. Results : This result showed that after a certain healing period, both hip joint angles showed a significant difference while there was no significant difference in the knee and ankle joint angles. After surgery, the angle of ankle dorsiflexion was smaller on the operated side than the opposite side compared to the pre-surgery measurements. Conclusion : After surgery, the asymmetry in a standing position left unchanged due to contracture of the knee joint and tightness in the hamstring muscle. Therefore, when physiotherapists plan an initial exercise programs for TKR patients, it is essential to apply adequate exercises which consider the contracture of the leg joints.
