Purpose: The purpose of this study was to evaluate performance reliability of stroke patients using kinematic analysis. Methods: A protocol to evaluate performance reliability was performed for three tasks on 20 stroke patients and 10 normal people. The tasks include hand to head (HH) task, hand to mouth (HM) task, and hand to target (HT) task. Results: The affected arms showed smaller joint angle, slower peak velocity, longer time to peak velocity for task performances than control group. Also, slower peak velocity and longer movement time for task performance in unaffected arm of stroke patients were obtained compared with the control group. Conclusion: Kinematic analysis is very useful quantitative tool to provide understanding on upper extremity function of stroke patients.

Purpose: To determine the effects of 10 % lidocaine spray and aroma hand massage on pain, anxiety, blood pressure, and pulse during arteriovenous (AV) fistula needling in hemodialysis (HD) patients. Methods: This study used a quasi-experimental design. Forty HD patients were assigned to either 10 % lidocaine spray group (n=21) or aroma massage group (n=19). 10 % lidocaine was sprayed 3 times around AV fistula 10 minutes before. Aroma hand massage was performed for 5 minutes with fluids containing 2 % of lavender, peppermint, and geranium concentrate mixture. Pain, anxiety, blood pressure, and pulse were measured during AV fistula needling without any intervention on the first week and during interventions on the second week. Data were analyzed with ${\chi}^2$ test, Fisher's exact test, t-test, paired t-test and MANCOVA. Results: Pain and anxiety were significantly decreased in both the lidocaine spray group and aroma massage group. Aroma hand massage was more effective to reduce pulse during AV fistula needling. Conclusion: The results suggest that 10% lidocaine spray and aroma hand massage may be effective to reduce pain, anxiety, and pulse during AV fistula needling in HD patients.

We have conclusions after the study of muscular system about large intestine channel of hand yangmyung muscle. 1. Judging from many studies of interrelation between Meridian muscle and muscle. it is considered that Meridian muscle theory has some similarities with modern anatomical muscular system. 2. There is a wide defference betwean myofacial pain syndrome and meridian muscle theory in that the former explains each muscle individually, while the latter classifies muscles systematically in the view of organism. 3. It is considered that large intestine channel of hand yangmyung muscle contains extensor digitorum muscle, extensor muscle of index finger, brachioradialis muscle, triceps brachii muscle, Rhomboid major muscle, trapezius muscle, sternocleidomastoid muscle and muscle levator labii. 4. The symptoms of large intestine channel of hand yangmyung muscle is similar to referred pain of modern Myofacial pain syndrome, and the medical treatment of "I-Tong-Wi-Su" is similar to that of Myofacial pain syndrome.

The virtual reality training has been suggested as an intervention to improve physical function. But, the effects of virtual reality training focused on improving ADL in patients with acute stroke are unclear. Purpose of this study was to examine the effect of virtual reality training on hand function and activities of daily living (ADL) in patients with acute stroke. Sixteen patients with acute stroke were included in this study. The experimental group (VRA group) received 30 minutes of virtual reality training focused on ADL for each session, while the control group received 30 minutes of conventional virtual reality training. To examine the hand function and ADL of the subjects, the study used Jebsen-Tylor Hand Function Test (JTHFT) and Korean Modified Barthel Index (K-MBI), respectively. Both groups showed significant improvements in hand function of affected and unaffected sides, and in K-MBI total score before and after the intervention. The experimental group showed significantly greater improvements in the self-care domain of K-MBI after intervention than the control group. These findings suggest that the virtual reality training focused on ADL may have a better effect on self-care than conventional virtual reality training in patients with acute stroke.

Object : The purpose of this study was to investigate aging-related changes of intrinsic and extrinsic hand muscles in their strength, cross-sectional area and volume, force control, and multi-digit synergies. It was hypothesized that aging would negatively affect distal muscles (intrinsic muscles) more than proximal muscles (extrinsic muscles). Method : Nine young and eleven older right-handed participants underwent MRI scans of the hand and forearm. Muscle cross-sectional areas and volumes of the intrinsic and extrinsic hand muscles were determined. Result : Muscle volume of the intrinsic muscles were larger in the younger group than the older group while muscle volume of the extrinsic muscles did not differ. For the cross-sectional area, both the intrinsic and extrinsic muscles of the younger group were larger than the older group. The maximum strength of the intrinsic muscles of the young group was 31% greater than the older group ($399.1{\pm}26.4$ vs $270.2{\pm}22.9Ncm$, p < 0.05) while the extrinsic muscles showed no significant difference. Although the elderly group showed a trend of decreased force control and multi-digit synergies, no statistical differences were found. These findings indicate aging-related decreases in hand muscle size and strength affect intrinsic muscles more than extrinsic muscles, thus supporting the hypothesis that sarcopenia affects the muscle size and strength of distal muscles more than proximal muscles. Conclusion : The aging-related decreases in hand muscle size and function were more apparent in intrinsic hand muscles, located more distally, than extrinsic muscles, located more proximally.

This paper proposes an ionic polymer metal composite (IPMC) based artificial muscle to be applicable to the Myoelectric hand prosthesis. The IPMC consists of a thin polymer membrane with metal electrodes plated chemically on both faces, and it is widely applying to the artificial muscle because it is driven by relatively low input voltage. The control commands for the IPMC-based artificial muscle is given by electromyographic (EMG) signals obtained from human forearm. By an intended contraction of the human flexor carpi ulnaris and extensor carpi ulnaris muscles, we investigated the actuation behavior of the IPMC-based artificial muscle. To obtain higher actuation force of the IPMC, the single layered as thick as $800[{\mu}m]$ or multi-layered IPMC of which each layer can be as thick as $178[{\mu}m]$ are prepared. As a result, the bending force was up to the maximum 12[gf] from 1[gf] by actuating the single layered IPMC with $178[{\mu}m]$, but the bending displacement was reduced to 6[mm] from 30[mm]. The experimental results using an implemented IPMC control system show a possibility and a usability of the bio-mimetic artificial muscle.

Purpose: This study was to evaluate the effects of a rehabilitation exercise program on physical function and mental health status in chronic stroke Patients with hemiparesis Method: This study used a single group experimental design with repeated measures. Data collection and intervention were done from August, 2004 to November. 2004 at a community. Participants were fifteen patients (mean age: 68.6), and a 100 meter walking time and box and block tests were conducted at baseline, 4weeks, and post-intervention (8weeks) Activities of daily living and the levels of depression and anxiety were measured by using SCL-90-R at pre and post Intervention. This program consisted of 1 hour individual exercise 3 times a week for 8 weeks, and it focused on stretching, walking, arm and hand exercise, and hand massage. Result: 1. ADL, IADL, and the 100m walking time in the patients were improved compared with baseline. However. box and block tests was not shown significant improvement compared with baseline. 2. Depression and anxiety scores were improved more than that of baseline. Conclusion: The rehabilitation exercise program can be effective in improving physical function and mental health status, and it has a potential for improving Physical health status in Patients with chronic stroke hemiparesis.
