Objectives : The purpose of this study was to identify the effect of electro-acupuncture stimulation regarding restoration of range of motion on patients with frozen shoulder. Methods : Experimental group measured with shoulder flexion and abduction angle at pre and post electro-acupuncture stimulation. Results : There were statistically significant difference regarding change of flexion angle of electro-acupuncture stimulation(p<0.01) and the testing value of all levels had a significant difference with the value of final post-test(p<0.01). There were statistically significant difference regarding change of abduction angle of electro-acupuncture stimulation(p<0.01). Conclusions : Electro-acupuncture stimulation of distal part increased range of motion of frozen shoulder. Therefore, application of electro-acupuncture should be developed as a therapeutic method in treatment of frozen shoulder. Also, it can contribute as one of good therapeutic methods offered to patients through approach of oriental rehabilitation medicine.

Objective : To investigate the biomechanical effects of a newly proposed Interspinous Process Compressor (IPC) and compare with pedicle screw fixation at surgical and adjacent levels of lumbar spine. Methods : A three dimensional finite element model of intact lumbar spine was constructed and two spinal fusion models using pedicle screw fixation system and a new type of interspinous devices, IPC, were developed. The biomechanical effects such as range of motion (ROM) and facet contact force were analyzed at surgical level (L3/4) and adjacent levels (L2/3, L4/5). In addition, the stress in adjacent intervertebral discs (D2, D4) was investigated. Results : The entire results show biomechanical parameters such as ROM, facet contact force, and stress in adjacent intervertebral discs were similar between PLIF and IPC models in all motions based on the assumption that the implants were perfectly fused with the spine. Conclusion : The newly proposed fusion device, IPC, had similar fusion effect at surgical level, and biomechanical effects at adjacent levels were also similar with those of pedicle screw fixation system. However, for clinical applications, real fusion effect between spinous process and hooks, duration of fusion, and influence on spinous process need to be investigated through clinical study.

Cranes are generally used to drop or lift equipment or materials. The present study focuses on equipment used for dropping and lifting the sonar system for undersea exploration. This study deals with a GA-based MATLAB$^{(R)}$ simulation for the design optimization of a new overboarding prototype with a two degree-of-freedom mechanism, including a parallelogram link, which is efficient in sonar system operation and maintenance. First, the strengths and weaknesses of the existing overboarding mechanisms are analyzed. The new mechanism to solve these problems is then suggested. For the proposed mechanism, the GA-based MATLAB$^{(R)}$ simulation technique is applied to the proposed mechanism to optimize the link lengths and the actuator lengths. By doing this, the mechanism cannot interfere in the hull's internal environment. Hence, the work range of motion (ROM) is satisfied, and good torque-angle properties are obtaind. The developed technology will be helpful in calculating the maximized output torque of the actuator for the application in practice using a similar type of the proposed mechanism.

The objective of this study is to report the improved case of Korean medicine treatment with Aconitum ciliare decaisne pharmacopuncture for supraspinatus tendon full-thickness tear. We used Aconitum ciliare Decaisne pharmacopuncture with other Korean medicine treatments (acupuncture, electroacupuncture, and cupping) for this patient. This case is measured and assessed by the numerical rating scale (NRS), shoulder range of motion (ROM), shoulder pain and disability index (SPADI) and shoulder physical examination. As the result, we found the improvement of NRS, SPADI, ROM, and shoulder physical examination. This study suggested that Korean medicine treatment with Aconitum ciliare Decaisne pharmacopuncture is proved to be helpful to relieve pain and recover function for supraspinatus tendon full-thickness tear. But further clinical studies are needed to clarify the effect of Aconitum ciliare Decaisne pharmacopuncture therapy for patients with supraspinatus tendon full-thickness tear.

The purpose of this study was to find the effects of scapular pattern and hold-relax technique of propriocetive neuromuscular facilitation(PNF) on the range of motion(ROM) and to find the effects of pain relieve through visual analogue scale(VAS) in frozen shoulder patients. The subjects were consisted of thirty frozen shoulder patients(men ; 9, women ; 21). The measurement of the shoulder range of motion was taken by measuring the degrees of flexion, abduction, and external rotation with a goniometer and the measurement of pain was performed by VAS from pre treatment to one to four weeks The results were as follows : 1. There was the statistical significance not only in the range of motion such as shoulder flexion, abduction, and external rotation, but also in VAS during four weeks(p<.05). 2. By the result of Scheffe's multiple comparison test. there was statistical significance between the values of pre treatment and treatment after one week in the range of motion of shoulder flexion. In that of shoulder external rotation, there was statistical significance between the values of pre treatment and treatment after one week, and between those of treatment after one and two weeks. As the result of this statistical significance of shoulder external rotation, the early treatment was thought to be more effective. However, there was statistical significance in the treatment after two and three weeks in shoulder abduction and was statistical significance between the values of pre treatment and the treatment after one weeks, and between those of treatment after two and three weeks in VAS (p<.05). 3. There was not statistical significance between men and women in the range of motion of the shoulder and in VAS(p>.05). 4. There not statistical significance between th right and left frozen shoulder patients in the range of motion of shoulder and in VAS(p>.05).

Purpose: Stretching exercises are commonly used in conjunction with sports and rehabilitation. Weassessed the immediate effects of stretching on passive stiffness of the hamstring muscles and knee range of motion (ROM) using three stretching techniques. Methods: A total of 45 participants were recruited. Isokinetic equipment was used to measure the passive stiffness of hamstring muscles and an inclinometer was used to measure active and passive ROM of the knee joint pre and post stretching. Stiffness was then calculated based on the incline of the torque-angle relationship. The test conditions for Group I were $3{\times}30$ seconds of static stretches using the hamstring muscle, Group II were $3{\times}30$ seconds of static stretches using the hamstring muscle with ankle dorsiflexion, and Group IIII had $3{\times}30$ seconds of active stretching. Results: Group II had significantly higher excursion of active ROM and Group IIIhad significantly higher excursion of passive muscle stiffness. All of the groups had significantly higher active and passive ROM and significantly lower muscle stiffness after stretching. The participants showed no change in hamstring muscle stiffness on the following day. Conclusion: Stretching has significant acute effects on ROM and muscle stiffness and canbe used in warm-up protocols for reducing muscle stiffness before a variety of exercise programs.

Purpose: The purpose of this study was to investigate the correlations between functional movement screen (FMS) and ankle dysfunctions in subjects with chronic ankle instability (CAI). Methods: This study was a cross-sectional study of 20 participants with CAI. The ankle dorsiflexion range of motion (ROM), Foot and Ankle Disability Index (FADI), center of pressure (COP) path length, and COP velocity for ankle dysfunction were measured in all the subjects. All the subjects underwent the FMS concerned with ankle functions consisted of deep squats, hurdle steps and in-line lunges. The Spearman rank-order correlation coefficient was used to determine relationship between the ankle ROM, FADI, COP and FMS. Results: The results of the deep squat and in-line lunge exercises revealed a significant correlation with the ankle dorsiflexion ROM, FADI, COP path length, and COP velocity. The hurdle step showed no correlation with the ankle dorsiflexion ROM and FADI but a significant relationship with the COP path length and COP velocity. Conclusion: The results of this study showed that relationship deep squat and in-line lunge and it is suggested that an assessment tool using ankle dorsiflexion ROM and ankle instability would be clinically effective.

Purpose : The purpose of this study was to investigate the correlation between shoulder gradient, range of motion of the neck, and subjective pain level of the potential risk group of smart-phone addiction. Methods : The subjects of this study were 90 women's who had potential risk of smart-phone addiction. VAS was used to measure subjectively pain intensity. Global Postural System was used to measure forward head posture. CROM was used to measure flexion, extension, lateral flexion of cervical range of motion. Results : The results of this study showed that was significant positive correlation between the both shoulder gradient, and cervical range of motion(p<.05). Statistically significant negative correlation between the VAS and left lateral flexion(p<.05). Conclusions : The difference between the gradient of both shoulders increased with the use of smart-phone addiction, and the cervical left lateral flexion decreased as the pain increased. This suggests that recognition on decrease of using smart phone and postural correction is necessary.
