The purpose of this study was to use as a basic data to develop suitable nursing intervention program and decide an appropriate intervention time after assessing shoulder range of motion in postmastectomy from 2 weeks to 3 month. 147 patients are chosen as study subject among patients who were in recovery of 2weeks, 1month, 2months and 3 months after surgical operation which is modified radical mastectomy. Data were collected at oncology medicine local and general surgery local in Seoul National University Hospital from May, 2003 to October, 2003. The range of motion of the shoulder(flexion, extension, abduction, internal rotation, external rotation) were examined. Analysis of data that shoulder range of motion average and standard deviation, percentage of the unaffected side and affected side compare with normal shoulder range of motion. Paired t-test was adopted to analyze the difference between affected side and unaffected side. Conclusion from this study is as following, 1. The most serious problem was external rotation (0.56%) and internal rotation is the next (19.9%) in 5 kinds of shoulder range of motion in 2 weeks after surgical operation 2. There was no difference in internal rotation after post operation 3 months but there were differences and shown to recover more than 90% in flexion and abduction. Also shoulder function incresed in flextion less than 80% and more than 80% in external rotation. As this study finding was shown that shoulder range of motion did not get back perfectly except of internal rotation and extension in point of 3 months after breast cancer surgical operation. External rotation was specially shown the lowest result so it is needed to exercise for improving their physical functioning recovery in postmastectomy patients. And it is suggested to study for helping to postmastectomy patients' physical and psycosocial functions with the early rehabilitation program which is based on these results.

Hemiplegic patients who suffered from a stroke struggle with a deterioration in upper limb functions, which can both be psychologically and physically discomforting; this can also limit patients' daily tasks involving any upper limb motions. In this study, we developed an assistive device for hemiplegic patients to improve their upper limb functions. It was manufactured to train patients by using their grip strength and the range of motion of the arm. Furthermore, we produced game contents in virtual reality to induce users' immersion and interaction. It was configured as a multi-player game to help ease the mental burden of receiving the training alone, hence allowing the patient and the caregiver to join the rehabilitation training simultaneously. The assistive device and game contents developed in this study enables patients and caregivers to easily check the degree of improvements in upper limb function by viewing quantitative analysis and visualized results.

The purpose of this study was to investigate the differences between two inflatable kayak by recording performance related variables during the kayak forward stroke motion. A total of 5 elite high school kayak players were recruited to participate while their kinematics and muscle activations were recorded while performing inside their high school swimming pool. Boat velocity, boats swaying angle, the average angular velocity and were used to evaluate the boats performance. The player's trunk rotational range of motion, knee flexion-extension angle range of motion, maximum trunk rotation angle, the knee flexion-extension angular velocity, and the upper and lower limb muscle activations were calculated and analyzed for the player's efficiency evaluation. There were no significantly different variables for the player's kinematics and their muscle activations for the two conditions. The B kayak was significantly faster than the A kaya. In addition there were no significant differences between the remaining variables for the two kayaks. In conclusion, the B kayak was faster than the A kayak, but neither of the kayaks had an influence on the player's performance variables.

The purpose of this study was to evaluate the effects of wearing Head-Mounted Display (HMD) on the cervical range of motion (CROM), neck muscle thickness, and pain in healthy young adults. The HMD group(male=16, female=7) was asked to perform sitting comfortably in a backless chair with hands on their knees with the HMD was worn on their heads to watch the video for 30 minutes. The control group(male=15, female=8) was asked to sit in the same posture as the HMD group for 30 minutes. CROM, neck muscle thickness, and pressure pain threshold (PPT) of both the upper trapezius and levator scapulae were measured before and after intervention. CROM and PPT of the upper trapezius and levator scapulae in the HMD group were significantly decreased and the thickness of the muscles in the HMD group were significantly increased more than in the pre-test (p<.05). There was no significant difference in CROM, muscle thickness, and PPT in the control group. Wearing HMD for a long time can cause a decrease in CROM and PPT and an increase in muscle thickness, and there is a risk of developing musculoskeletal disorders in the neck and shoulder. Therefore, this study recommends maintaining the correct posture of the neck and shoulder and using HMD only for an appropriate time.

This study was conducted to develop an individualized upper extremity exercise program for patients after mastectomy and evaluate its effectiveness. A nonequivalent control-group pretest-posttest design was used for this investigation. Research participants were patients with breast cancer who underwent mastectomy at two university hospitals (experimental group, n=17; control group, n=16). The experimental group received an individualized upper extremity exercise program three times a week for 7 weeks. Data were analyzed by the ${\chi}^2-test$, Fisher's exact test, Mann-Whitney U-test and Wilcoxon Signed Rank test using SPSS WIN 21.0. Inter-group comparison revealed significant differences between pre-test and post-test in hands behind the back, flexion, abduction, external rotation, internal rotation, and grip strength. Moreover, the experimental group showed significant improvements in hands behind the back, flexion, abduction, external rotation, internal rotation, and grip strength relative to the control. In conclusion, the individualized upper extremity exercise program was shown to be an effective intervention to improve physical functions in upper limbs and shoulders. Therefore, this program should be applied to patients after mastectomy in clinics since many patients have suffered from decreased physical functions in upper extremities.

The purpose of this study was to examine the effects of coordinative locomotor training (CLT) program on the balance for the promotion of life care of elderly obese women. Ten participants of elderly obese women who were able to walk independently without surgery experience of lumbar, hip or knee joint within the past year were recruited and under went the pretest, CLT (20 sessions), followed by the post-test. The test included BMI test using In-body, joint kinematics using myoVIDEO, muscle activation using surface EMG test (erector spinae (ER), external oblique abdominalis (EO), quadriceps femoris (Quad), hamstring muscle (Ham)) and balance tests including dynamic balance test using forced treadmill, Berg balance scale (BBS) and timed up go (TUG). The CLT program was conducted 60 minutes a day, 5 days a week, over 4 weeks period. As a result of this study, The the trunk and hip joints kinematics during the stance and swing phases of gait were a statistical significance levels were set at p <0.05. The ER and EO muscle activation were significantly improved after intervention (p <0.05). The length of gait line and single support line of change of center of pressure (COP) were significantly increased after intervention (p <0.05). The BBS and TUG were also significantly enhanced after intervention (p <0.05). The results of this study showed that CLT program for the improvement of life care had significant effects on improving postural instability, muscle weakness, reduced balance ability and falling risk of obese elderly women. Therefore, it is recommended to apply CLT program to improve life-care through improving balance ability and preventing fall of obese elderly women.

본 연구에서는 한국인 표준체형과 유사한 사람의 의료 영상 자료를 이용하여 인체 골격계 모델을 개발하였다. 이를 동역학 해석 상용 소프웨트어인 RecurDynTM에 탑재하여 인체 시뮬레이션 모듈을 개발하였고 타당성을 검증을 거친 후 노인의 앉기-서기 및 보행 동작해석에 적용하였다. 노인이 보행기(elderly walker)를 사용하여 앉기-서기 동작을 할 때 하지관절 기구학의 변화는 미비하였으나 보행 시 각 관절의 가동범위가 감소하였고 동작시간이 증가하였다. 또한 근전도 해석결과 일부 발목 주변 근육들과 햄스트링 근육에서 근활성치가 줄거나 활성시간이 줄었다. 이러한 변화는 보행기를 이용한 보행 때 하지의 기여도가 감소했기 때문에 발생하는 현상으로 생각된다. 본 연구를 통해 얻어진 시뮬레이션 기술은 다양한 인체 정보 콘텐츠분야에 널리 활용될 것으로 생각된다.
