Purpose: This study covered the effect of shoulder stabilization exercise on muscle activity, postural alignment and self-efficacy of the elderly people with round shoulders by visiting village hall in rural area. Methods: 40 elderly people with round shoulders were recruited for this study (experimental group: 20 subjects and control group: 20 subjects). The experimental group was asked to perform shoulder stabilization exercise 60 minutes per one time for 8 weeks and three times in a week and the control group was asked to receive education related to pain management for the initial one time. Before and after the experiment, we measured the subjects' muscle activity of upper trapezius, serratus anterior, infraspinatus, pectoralis major and the lower trapezius, then postural alignment of craniovertebral angle and round shoulder posture. In addition, self-efficacy is measured through the questionnaire. Results: Compared to the control group, the experimental group showed significant differences in the muscle activity of all muscles, posture alignment of the craniovertebral angle. round shoulder posture, and improvement of self-efficacy. Conclusion: We found that shoulder stabilization exercise is effective in muscle activity, postural alignment and self-efficacy of the elderly people through visit-rehabilitation service. This study can be used for improving the physical and mental abilities through active visit-rehabilitation service for areas where have poor medical benefits. It is considered that systematic visit rehabilitation service should have institutional framework ultimately.

Purpose: The purpose of this study was to investigate the effects of neck stabilization exercise with PNF for neck alignment, neck disability index, and sitting balance in adults with forward-head posture. Methods: Forty participants were randomly assigned to two groups. Patients in the neck stabilization exercise group (NSG, n = 20) and the proprioceptive neuromuscular facilitation neck pattern exercise group (PNFG, n = 20) were studied 30 minutes a day three times a week for four weeks. Outcomes were measured using cranial vertical angle (CVA), the Korean version of the neck disability index (KNDI), anterior limit of stability (ALOS), and posterior limit of stability (PLOS) before and after the intervention period. Results: There were significant effects in the CVA and the KNDI of both groups pre- and post-intervention. There were significant effects in ALOS and PLOS in the PNFG pre- and post-intervention compared with the NSG. Conclusion: The results of this study suggest that PNF with neck exercise could be beneficial to the static balance of adults with forward-head posture.

Objective: This study attempted to compare the effects of bridge exercise using a sling according to the angle of the ankle to confirm the effective lower extremity muscle activation posture of patients with patellofemoral pain syndrome(PFPS). Design: Cross-sectional study Methods: Seventeen patients with PFPS were recruited and the muscle activities of the vastus medialis, vastus lateralis, rectus femoris, and gluteus maximus were measured according to the ankle position (dorsiflexion, neutral, plantar flexion). After measuring the maximum number of isometric contractions of vastus medialis, vastus lateralis, rectus femoris, and gluteus maximus, bridging exercise using a sling according to each ankle posture was applied to measure lower extremity muscle activity. The evaluation was performed 3 times for 10 seconds. The three ankle postures were randomly performed and the average values were compared. Results: As a result of this study, the vastus medialis muscle showed high muscle activity in the order of dorsiflexion, plantar flexion, and neutral position bridge exercise (p<0.05). And the vastus lateralis showed high muscle activity in the order of dorsiflexion, neutral, and plantar flexion (p<0.05). However, rectus femoris and gluteus maximus did not show significant muscle activity according to the ankle posture, but muscle activity was highest in the dorsiflexion posture. Conclusions: As a result of this study, muscle activity was high in the order of vastus medialis and vastus lateralis during ankle dorsiflexion. This is thought to be a major factor that can be applied in various ways in clinical practice according to the ankle angle when treating PFPS patients.

PURPOSE: This study examined the effects of an exercise program for the thoracic spine and scapula rather than the neck, which is the primary site of pain. METHODS: Thirty-two elementary school teachers with a forward head posture (FHP) were assigned randomly to either the experimental group (n = 16) or the control group (n = 16). The experimental group performed scapular stabilization exercise (SSE) and thoracic extension exercise (TEE), and the control group performed cervical self-myofascial release exercise and stretching exercise. The pulmonary functions, pain, craniovertebral angle (CVA), and cervical range of motion (CROM) were measured before the intervention and six weeks after. RESULTS: The within-group comparisons showed that the VAS and CROM (except for extension) in both groups were significantly different before and after the intervention (p < .05). The changes in the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), and CVA were significant only in the experimental group (p < .05). The between-group comparisons showed a significant difference in the FVC, FEV1, VAS, CVA, and left lateral flexion (p < .05). CONCLUSION: The combination of SSE and TEE in the experimental group was more effective in improving the FHP and breathing ability. Moreover, the experimental group and control combination appeared to be effective in reducing pain and improving the CROM. The combination of SSE and TEE, which are exercises that do not target the cervical spine directly, was effective in improving the posture, respiration, neck pain, and CROM in elementary school teachers with FHP.

Background: Scapular posterior tilt (SPT) is important in the prevention of abnormal scapular movement and pain during elevation of the arm. However, previous studies have overlooked increased upper trapezius (UT) muscle activity interrupting the normal force couple of scapular motion and compensation of levator scapulae (LS) muscle activated simultaneously with UT during SPT exercise. Objects: The purpose of this study was to compare the effects of modified SPT with depression exercise versus SPT exercise on serratus anterior (SA), lower trapezius (LT), UT, and LS muscle activities and the clavicular tilt angle, in subjects with rounded shoulder posture (RSP) and myofascial pain in the UT muscle region. Methods: Eighteen subjects with RSP were recruited and randomly allocated to 2 groups; 9 in the SPT group and 9 in the SPT with depression group. All subjects met the specific RSP criteria and had myofascial pain of UT region. Depending on the allocated group, subjects performed the assigned SPT exercise and EMG data were recorded during the each exercise. Clavicular tilt angle was defined as the angle between the line joining the medial and lateral end of the clavicle and a horizontal line. Results: The SA muscle activity was significantly greater in SPT with depression than with SPT exercise (p<.05). The UT, LS muscle activity and the clavicular tilt angle was significantly lower in SPT with depression than with SPT exercise (p<.05). Conclusion: These findings were insightful because the potential risk of pain from overactivation of the UT and LS was considered, in contrast with SPT exercise. SPT with depression exercise can be implemented as an effective method to facilitate scapular muscle activity for stability and to prevent myofascial pain in the neck and shoulder.

Purpose : The purpose of this study is to investigate the effect of squat exercise using a ball on the gap between knees and Q angle of a subject with a genu-varum, and to prove the effect, to provide a clinical basis for developing into a knee correction exercise program. Methods : As a result of posture measurement through GPS, 26 female with genu-varum with a knee length of 5 cm or more were studied. The group was randomly assigned to 13 squat exercise group using ball (experimental group) and 13 general squat exercise groups (control group). The experimental group placed the ball between both knees in a position where the distance between both feet was slightly wider than the shoulder width on a flat support surface, and fixed the ball, and then squat with the start signal. The control group squats without a ball. Each group performed three sets of exercise three times a week for six weeks. Before their exercise, after three and six weeks, EMG, GPS, digital goniometer measurement, the vastus medialis (VM), the vastus lateralis (VL), and the Q-angle were measured in the squat exercise posture. EMG was measured in squat exercise posture. Results : The distance between the knees was reduced. EMG is activated in group A, the group B experimental results showed the high activity of the VL. Q-angle had increased. But the experimental group increased more than the control group. Conclusion : We have confirmed through our experiments that the distance interval between the knees during squat exercises using a ball can be reduced. Furthermore, it would also be helpful to ensure the treatment of genu-varum.

Objective: Tension-type headache is caused by hormones, foods, irritants, stress, obesity, fatigue, and neck and head trigger points-prolonged abnormal posture. The purpose of this study was to evaluate the effects of relaxation approach on head posture, static postural stability, and headache in persons with tension-type headache. Design: Randomized controlled trial. Methods: Thirty-five persons with tension-type headache participated in this study. This study was a pretest-posttest with a control group design for a duration of 4 weeks (60 min/3 times/1 wk). The participants were randomly allocated to the relaxation approach group (n=18) and the control group with conventional rehabilitation including thermotherapy and transcutaneous electrical stimulation for the same period (n=17). Outcome measures involved forward head posture (FHP), foot pressure, neck disability index (NDI), and six-item headache impact test (HIT-6). Results: Relaxation approach and control groups improved significantly in the amount of forward head posture, neck disability index, and six-item headache impact test scores after training (p<0.05). The control group was found to be significantly different in the amount of FHP, backward foot pressure, NDI, and HIT-6 after training compared to before training (p<0.05). The relaxation approach group significantly improved in forward head posture, neck disability index, and six-item headache impact test compared with control group after training (p<0.05). Neck disability index and six-item headache impact test significantly improved after training compared with before training in the control group (p<0.05). However, the foot pressure was not significantly different between relaxation approach and control groups. Conclusions: This study suggests that treatment with relaxation approach combined with self-exercise would be effective in reducing the amount of forward head posture, neck disability and headache impacts.

본 연구의 목적은 거북목을 가진 사람에게 메켄지 폄운동과 어깨안정화운동이 앞쪽머리자세에 미치는 영향에 대해 알아보는 것이다. 연구대상자는 30명의 거북목을 가진 평범하고 건강한 사람들로 이루어져 있다. 대상자는 어깨안정화운동과 메켄지 폄운동으로 나누어(인원=30, 남자 15명, 여자 15명) 무작위로 나누어 6주 동안 실시되었다. 본 연구는 마름근, 아래등세모근의 운동프로그램과 깊은목굽힘근, 위등세모근, 어깨올림근의 신장프로그램을 통한 목뼈의 머리척추각(Cervical Vertebra Angle) 값과 각 근육별 근전도의 차이를 알아보았다. 앞쪽머리자세와 경우에는 목과 등근육의 활성도가 감소하고 피로도는 증가함을 보였다. 이러한 결과는 목과 머리의 불안정한 상태를 안정시키기 위해서는 위등세모근, 깊은목굽힘근, 어깨올림근의 신장과 마름근, 아래등세모근의 운동을 통해 거북목의 개선에 긍정적인 변화를 줄 것으로 보인다. 이러한 근육들의 불균형한 수축과 과도한 긴장으로 근육의 경직과 피로가 누적되며 이러한 상태가 계속 유지되게 되면 만성화상태가 되어 근육의 불균형으로 인해 통증을 유발할 수 있으며, 피로의 누적으로 인하여 자극에 대한 반응과 근력을 약화시켜서 목 디스크가 발생할 확률이 높아질 것으로 사료된다.

Purpose : The purpose of this study was to investigate the effects of combined cervical stabilization exercise (CSE) and stretching exercise (SE) on office workers with forward head posture (FHP). Methods : A total of 32 office workers with forward head posture were randomly assigned to experimental (n=16) and control (n=16) groups. The experimental group underwent combined CSE and SE, and the control group underwent cervical self-myofascial release and SE. Both groups performed exercises for 40 min per day, thrice per week for a total of 6 weeks. Craniovertebral angle (CVA), respiration, disability, and joint range of motion (ROM) before and 6 weeks after intervention were measured and compared. Results : There was no significant between-group difference in the general characteristics (p>.05). The intra-group comparison showed significant differences in the visual analog scale (VAS) and neck disability index (NDI) of both groups post-intervention (p<.05). CVA and forced expiratory volume in 1 seconds (FEV₁) were significantly improved post-intervention in the experimental group only (p<.05). In the experimental group, all ROM variables were significantly improved post-intervention. In contrast, in the control group, all ROM variables improved significantly post-intervention, except for extension (p<.05). The inter-group comparison showed significant differences in NDI, left lateral flexion, right lateral flexion, and left rotation between the two groups (p<.05). Conclusion : The combination of CSE and SE, which stabilizes the cervical spine, had positive effects on cranial rotation angle, respiration, disability, and joint ROM in office workers with forward head posture. Therefore, the combination of the two exercises may be an effective option to reduce symptoms and prevent postural problems in office workers with FHP.
