This study investigated the changes in inflammatory mediators, immunocompetent cells and bone merrow progenitor cells by the magnitude of muscle damage and type of the muscle contraction in the elderly. Twenty older adults who had not been involved in a resistance-training program at least 6 months prior to the present study were assigned to eccentric exercise group (ECC, n=10) and concentric exercise group (CON, n=10). All subjects performed 10 sets of 6 maximal isokinetic eccentric (ECC 1) or concentric (CON) contractions with the non-dominant arm in a randomized, with 4 wk between bouts (ECC 2). Skeletal muscle damage index (ROM, VAS, Plasma CK), inflammation mediators (TNF-α, IL-1, IL-6), immunocomperent cells (CD3+, CD4+, CD8+, CD19+), bone merrow progenitor cell (CD34+) and leukocytes were measured before, immediately after, 2, 24, 48, 72, and 96 h after exercise. Changes in ROM and VAS were greater (P<.05) after ECC 1 than CON and ECC 2. Increases in TNF-α and IL-6 were greater (P<.05) 24, 48 and 72 h after ECC 1 than CON and ECC 2. Increases in neutrophils were greater (P<.05) 2 h after ECC 1 than CON and ECC 2. It was confirmed that muscle damage was greater following eccentric than concentric contractions as well as first bout than second bout in the elderly, and suggested that TNF-α, IL-6 and neutrophils should closely correlate with magnitude of muscle damage.

The purpose of this study was to examine the influence of extreme heat on muscle function and muscle injury marker in elderly women. The subjects of this study were eight post-menopausal elderly women without any metabolic disease. All eight subjects were asked to perform the knee joint isokinetic exercise using isokinetic equipment (cybex) in the laboratory and experimental temperature within laboratory was adjusted to two conditions: extreme heat temperature(33±0.5℃) and normal temperature(20±0.5℃) maintained in 50±3% humidity conditions. Each experimental exercise was monitored and analyzed the change of HSP70, LDH and CK. Muscular functions (peak torque, total work, percentage of peak torque body weight, fatigue index, average power and total work) were significant differences at exercise between temperatural conditions (p<.05). In extreme heat temperature, muscular injury markers (HSP70, LDH and CK) were increased, threfore resulted in significantly higher than normal temperature(p<.05). These results show that extreme heat temperature can decrease muscle function in elderly women.

The purpose of this study was to examine the differences in kinetics between 6 months of rehabilitation training and 12 months of rehabilitation training after total hip arthroplasty. 10 unilateral THA participants performed kinetic tests. Three dimensional kinematics and hip flexors and abductors electromyography (EMG) were collected during each trial. T-test was used for statistical analysis (p<0.05). There was no significant difference in EMG data between the two groups, but the mean comparison EMG data was higher in the 12 months rehabilitation training group than the 6 months rehabilitation training group. The moment value was found with motion-dependent interaction analyzing method which was used by Feltner and Dapena. There was no significant difference between moment values of the two groups. There was no significant difference between ground reaction forces of the two groups; however, there were some differences shown in Fz (vertical reaction force) between the two groups ($892{\pm}104\;N$, $820{\pm}87\;N$). The first peak impact force was about 9% lower in the 12 months group compared to the 6 months group. The second peak active force was nearly equal between the two groups. More research is necessary to determine exactly what constitutes optimal rehabilitation training biomechanics for patients with total hip arthroplasty.

Purpose : The purpose of this study was to find out which method was efficient to enhance the flexibility of lower back between PNF(proprioceptive neuromuscular facilitation) and hamstring stretching. Method : subject were 20 young people between the ages 20 and 25. subjects were randomly assigned to one of 2groups; PNF(n=10), static(n=10). respective group received the same stretching does of 3days per week for 4weeks. Trunk flexion forward a measuring instrument and tapeline were performed to measurement the flexibility of lower back at different times(before starting the exercise, 4weeks after starting). Results : The results of the study were as follows: The lower back flexibility was increased significantly in PNF groups. PNF, static groups showed meaningful defference in trunk flexion forward. The finding indicate that PNF may be preferred technique for improving flexibility and that flexibility training results in on increased consistency of flexibility scores.

For the self-directed rehabilitation of upper extremity hemiplegia patients, in this paper we propose an interface method capable of doing bilateral exercises in rehabilitation robotics. This is a method for estimating information of movements from the unaffected-side, and projects it to the affected-side in order. That the affected-side is followed the movements of the unaffected-side. For estimation of the unaffected-side movements information, gyro sensor data and acceleration sensor data were fused. In order to improve the measurement error in data fusion, a HDR filter and a complementary filter were applied. Estimated motion information is derived the one side of the drive input of rehabilitation robot. In order to validate the proposed method, experimental equipment is designed to be similar to the body's joints. The verification was performed by comparing the estimation angle data from inertial sensors and the encoder data which were attached to the mechanism.

The objective of the present study is to review of the system, type of care and utility of the Geriatric Health Care Facility(GHCF) in Japan. Geriatric Health Care Facilities in Japan were started with subsidies from the Ministry of Health and Welfare in 1987 to encourage return of the elderly from hospitals to their homes rather than other destinations such as nursing homes or hospitals. Concerning to the type of care, there is the difference between GHCF and other geriatric care facilities(i.e., geriatric hospital and nursing home). GHCF provides both medical and nursing care. The following services are available for the GHCF's user's. As institutional care services, rehabilitation training, ADL exercise, nursing care and management of medicine, are available. For the out-patients, supplying meals, taking a bath, and rehabilitation services, are also available. The medical treatment fee at the facilities is about US $ 1,500 per month. Expenses for meals, daily necessities, shall be borne by the recipient, Those expenses are about US $ 360 per month. In anticipation of the coming of the aging society, the Goverment must be formulated consecutively several vital policies of measures, especially GHCF, for the elderly in the future few years.
