Objective: Elderly people with dementia experience not only cognitive dysfunction but also motor function deficits, such as balance and gait impairments. Recently, transcutaneous electrical nerve stimulation (TENS) has been used to reduce pain as well as to control muscle spasm, spasticity and motor performance in various types of subjects. The purpose of this study determined the effect of a single trial TENS on balance and gait function in elderly people with dementia. Design: A randomized controlled trial. Methods: Twenty-two subjects with dementia were assigned to the TENS group (n=12) and ten subjects were assigned to the control group (n=10) randomly. Subjects were classified into two groups: the TENS group (n=12) and the placebo-TENS group (n=10). The TENS group had electrical stimulation applied on the calf muscle for 15 minutes, while the placebo-TENS group had not received real electrical stimulation. The timed up and go test (TUG) and functional reach test (FRT) were used to measure the balance function, and the 10 meters walk test (MWT) and 6MWT were used to assess gait ability. All tests were performed before and after intervention under a single-blinded condition. Results: After intervention, there were significant improvements in TUG, FRT, 10MWT, and 6MWT results in the TENS group (p<0.05), while the placebo-TENS group did not show significant changes in all outcome measurements. There were also differences in all tests between the two groups at post-measurements (p<0.05). Conclusions: This study demonstrated that a single trial TENS application on the calf may be used to improve balance and gait function in elderly people with dementia.

This study was conducted to clarify the effect of physical ability, pain, fatigue, depression, sexual satisfaction, and spouse criticism on the sexual intrusiveness of rheumatoid arthritis(RA)women. The subjects of the study were 89 RA outpatients who visited the department of rheumatology of Dong-A University Hospital in Pusan from March 2000 to April, 2000. Pain & Fatigue via graphic rating scale, depression via CES-D(Center for Epidemiologic Studies -Depression) scale and physical ability via the Health Assessment questionnaire(HAQ) were assessed. Also we used both Sexual satisfaction scale(Kim, et al, 1997) to measure sexual satisfaction and Spouse criticism scale(Kraaimaat et al. 1996) to measure spouse criticism. The Intrusiveness rating scale which was derived from Arthritis Impact Measurement Scale(AIMS) was used to measure illness intrusiveness in sexuality. The relationships between the variables such as pain, depression, fatigue, physical ability, spouse criticism, sexual satisfaction and illness intrusiveness on sexuality were analyzed by Pearson correlation. As a result, pain & depression were significantly positively related to illness intrusiveness and physical ability & sexual satisfaction was significantly negatively related to illness intrusiveness. But these variables were interrelated. So hierarchical regression was performed to examine the relative contribution of pain, depression, physical ability, and sexual satisfaction with regard to intrusiveness of RA on sexuality. It revealed that pain, depression & sexual satisfaction predicted significantly illness intrusiveness on sexuality. Therefore it is very important to reduce pain and depression and to increase sexual satisfaction for reducing illness intrusiveness.

Purpose: This study was performed to investigate the effect of joint mobilization on pain relief and cartilage repair in an induced osteoarthritis rat model by analyzing the expression of heat shock protein 70 in articular cartilage. Methods: MIA was injected into SD rats to induce osteoarthritis. These rats were divided into 4 groups: control group (n=30), no further treatment after the MIA injection ; experimental group I(n=30), performed swimming exercise after the MIA injection experimental group II (n=30), underwent joint mobilization after the MIA injection and experimental group III (n=30), performed swimming exercise and underwent joint mobilization after the MIA injection. For the histologic and pathophysiologic evaluation, safranin-O staining and for the immunohistochemical evaluation, the expression of HSP 70 in articular cartilage was analyzed 1, 7, 14, and 21 days after the MIA injection. Results: The inflammatory response and loss of tissue declined in experimental groups I and II over time, whereas the greatest decreases were noted in experimental group III. In the articular cartilage, low expression of HSP 70 was observed in every group on day 1, whereas HSP 70 expression was elevated on days 7 and 14 in experimental groups II and III. After 21 days, experimental group II displayed the strongest positive reaction, whereas HSP 70 was higher in experimental group III at this time point compared to that after 14 days. Conclusion: Our results showed that swimming exercise and joint mobilization had positive effects on pain relief and histologic and functional recovery in an induced osteoarthritis rat model.

Purpose: The purpose of this study was to compare the influence of external scapular stabilization on the isometric strength of shoulder flexor muscle in subjects with and without scapular winging and conditions with and without external scapular stabilization. Methods: A total of 30 subjects with and without scapular winging were enrolled. Two groups were classified using clinical and diagnostic tests to divide the groups with and without scapular winging (15 with scapular winging 15 without scapular winging). The isometric strength of the shoulder flexor was measured using a tensiometer. The isometric strength was evaluated in the sitting position with and without an external scapular stabilization. The external scapular stabilization was provided with the examiner's hand to fix scapular winging during shoulder flexion. The changing value was calculated to determine the isometric strength difference between shoulder flexion with and without the external scapular stabilization in each group. The changing value between isometric strength of shoulder flexor with and without scapular winging was compared using the independent t-test. Statistical significance was set at 0.05. Results: In the group with scapular winging, the shoulder flexor isometric strength in the sitting position was greater with an external scapular stabilization than without an external scapular stabilization (p<0.05). There was no significant difference in the shoulder flexor isometric strength in the subjects without scapular winging between conditions with or without an external scapular stabilization (p>0.05). Conclusion: The external scapular stabilization in the individuals with scapular winging may increase shoulder flexor isometric strength in the sitting position.

Purpose: This study examined the effects of heel insoles on the static balance and leg muscle activity and posture control strategy during external perturbation. Methods: Thirty healthy young men participated in the study. The subjects underwent two experimental conditions: 1) no heel insole condition (0cm) and 2) wearing heel insole condition (5cm). The static balance was measured using an I-Balance device, which measured the change in the center of gravity (COG). The onset time of muscle activation and muscle activation of the erector spinae (ES), hamstring (HAM), gastrocnemius (GCM) were measured using surface EMG electrodes to determine the change in posture control strategy during external perturbation. Results: The speed and distance of COG were significantly higher in the wearing heel insoles condition than the no heel insole condition (p<0.05). In addition, significant differences in the onset time of the GCM, HAM, and ES muscle activation were observed when there was no heel insole condition during external perturbation (p<0.017). On the other hand, no significant differences in the onset time of muscle activation were observed between GCM and HAM when wearing the heel insole condition during external perturbation (p<0.017). Moreover, muscle activation of the GCM was significantly higher in the wearing heel insoles condition than the no heel insole condition during external perturbation (p<0.05). Conclusion: These findings suggest that heel insoles may have disadvantages, and increased efforts are needed to maintain balance and change the posture control strategy during external perturbation.

Objective: The purpose of this study was to investigate the effects of resistance applied in various directions on lower extremity muscle activity and balance during squat exercise performance. Design: Cross-sectional study. Methods: Forty-one adults (19 males and 22 females) agreed to the study purpose and procedures. All subjects randomly performed squat exercises with an intensity of overcoming 10% of body weight resistance pulled forward, backward and general squats with $60^{\circ}$ of knee joint flexion. Electromyography was used to measure muscle activity of the vastus medialis oblique (VMO), rectus femoris (RF), vastus lateralis oblique (VLO), biceps femoris (BF), and semitendinosus (ST) muscles. The Wii Balance Board was used to assess balance during the three-method squat operation. Each operation was measured three times for 10 seconds. Results: There were significant differences in muscle activities of the VMO, RF, VLO, ST and balance ability with the application of three directions of resistance (p<0.05). Post hoc comparisons revealed that squats performed with resistance pulled in the backward direction resulted in higher VMO, RF and VLO activity than with the resistance placed in a pulled forward direction (p<0.05). In the ST, resistance applied in the pulled forward direction showed greater muscle activity compared to the pulled backward direction (p<0.05). With balance, squats performed with resistance pulled in the forward direction showed greater muscle activity than with resistance applied in the pulled backward direction and during general squat performance (p<0.05). Conclusions: In this study, squat exercises performed with resistance applied in the direction of pulling backwards was found to be the most effective in improving quadriceps muscle strength and balance. It is effective to provide resistance that is placed in the forward when it is difficult to perform a general squat due to weakness of the quadriceps.
