Purpose : The purpose of this study was to provide information for developing a rehabilitation intervention that improves adaptation and the quality of life after mastectomy by investigating the level of physical function and fatigue in mastectomy patients. Methods : The subjects were 63 patients selected from St. Mary's Kangnam hospital Data were collected from March to June, 2003. Physical function was measured by the range of motion of the shoulder joint, shoulder function, and physical symptoms. fatigue was measured by using the Brief Fatigue Inventory (BFI). Results : The range of motion on the affected side was significantly lower than that in the healthy side. Shoulder function score was highest in the item of 'pull on pants', and lowest in the item of 'back zipper'. Physical symptom score was highest in the item of 'numbness', and lowest in the item of 'Itching sensation'. The highest item interfered by fatigue was 'normal work (includes both work outside the home and daily chores)'. Conclusion : The result of this study suggests that effective rehabilitation intervention for mastectomy patients should be needed to improve physical function, and reduce fatigue.

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.

This study analyzes the effects of changes in running velocity and slope on the biomechanical factors of the lower limb joints. For this purpose, 15 adult males in their 20s ran according to changes in running speed (2.7, 3.3 m/s) and slope ( -9°, -6°, 0°, 6°, 9°) on the treadmill, and their running characteristics (stride length, stride frequency). The range of motion of the lower limb joint and the vertical ground reaction force were greater in UR (p <.05), and the moment of the lower limb joint, braking force, thrust and load factor was large in DR (p <.05). In joint power, the ankle joint was greater in DR, and hip joint was greater in the UR (p <.05). These results show that the injuries of the ankle joint will be greater than other cases when running DR at a speed of 3.3 m/s.

Purpose: The purpose of this paper is to determine effects of auricular acupressure on knee pain, range of motion, and sleep in the elderly with knee osteoarthritis. Methods: This is an experimental study designed with randomization and single-blind in a placebo-control approach. The subjects included the elderly with knee osteoarthritis who were using an elderly welfare facility. In each of the groups, 28 subjects were assigned. For the experimental group, auricular acupressure was applied to five pressure points related to the pain caused by osteoarthritis and sleep. In the case of the placebo-control group, auricular acupressure was applied to other five points than the former. The intervention lasted eight weeks. In order to examine intervention effects of auricular acupressure, joint pain, Pressure Pain Thresholds (PPTs), and extension and flexion range of motion (ROM) were measured weekly. As for the preand post-examinations, pain, sleep quality, and the time-by-sleep stage of the patients with knee osteoarthritis were measured. Results: The VAS scores in the experimental group with auricular acupressure significantly decreased through time (p<.001) and WOMAC also significantly decreased (p<.01) compared with the placebo-control group. However, there were no significant differences in PPTs. The flexion (p<.01) and extension (p<.001) ROMs measured for eight weeks improved over time. Meanwhile, sleep quality improved significantly after the intervention termination (p<.01), but there was no significant difference found in the time-by-sleep stage. Conclusion: Auricular acupressure applied for eight weeks was found to be effective in reducing joint pain, improving knee ROM, and improving sleep quality in patients with degenerative knee arthritis.

In this paper, we attempted to analyze the balance ability of the body by measuring changes in body motion and plantar pressure distribution. So we developed a program that can measure and analyze range of motion and center of body pressure using inertial measurement unit(IMU) and FSR(Force Sensing Resistor) sensor, we also produced a contents that can help improve the balance ability. The quantitative values of range of motion and center of body pressure measured by this program are visualized in real time so that the user can easily recognize the results. In addition, the contents were designed to be adjusted according to the direction of improving the balance ability by adjusting the difficulty level based on the measured balance information. This can be achieved by increasing the concentration and participation will by using visual feedback method that proceeds while watching moving objects according to the user's motion.
