Purpose: This study investigated the effect of taping therapy on metacarpophalangeal (MCP) disorders of the thumb. Methods: Twenty eight patients were enrolled in this study. They were randomly assigned to experimental (n=16) or a control group (n=12). The experimental and control groups received Ultrasound (Gymna Pulson 200) operating at a frequency of 3MHz and an intensity of $1.0W/cm^2$ with a 100% duty cycle for 10 minutes. The experimental group received, additionally, taping using Kinesiotape on the injured thumb. The following parameters were measured:pain during rest and flexion of the thumb, tenderness, range of motion (ROM), pinch and spherical grip power pre- and post-treatment. This study was carried out 3 days per week throughout the 2-week treatment. Results: There were significant improvements in pain during rest and flexion of the thumb, tenderness, ROM, pinch and spherical grip power between pre- and post-treatment times in both groups (p<0.05). However, there was a significant difference in all parameters between the experimental and control groups (p<0.05). Finally, the satisfaction level after intervention was significantly higher in the experimental group than in the control group (p<0.05). Conclusion: Taping is effective for treating pain and dysfunction in patients with thumb disorders.

Cervical spondylotic myelopathy (CSM) is a severe disease that usually needs surgical treatment. We have treated two CSM patients with Korean traditonal medicine, which includes acupuncture, pharmacopuncture, herbal medicine and manual treatment (Chuna). For objective evaluation, we used Nurick's classification, JOA (Japanses Orthopedic Association) score, grip and release test and hand grasping power measurement. Post-treatment analysis has shown that grip and release test score and grasping power of two patients were both remarkably improved, along with the improvements on both Nurick's classification and JOA score. This study showed that Korean traditional medicine could be effective conservative treatment for CSM.

The purpose of this study was to find out problems which occured between clothes and motor ability traits of the hemiplegic aged. The samples were 32 hemiplegic aged men and were compared with 43 healthy aged men. Motor ability of the samples were measured by ROM test, muscle power test and finger function test(grip strength, hand's coordination, lateral pinch, 3pt. pinch). Design of the clothes consisted of 25 variables and the analysis of dressing and undressing motion consist of 10 motions of dressing and undressing dress shirts and 8 motions of trousers. The results were as follows: 1. There were significant relationship between ROM and muscle power and finger function of the hemiplegic aged(P<.001). 2. There were significant differences between the nomal side's finger function of the hemiplegic aged and that of the healthy group(P<.001). 3. The designs of clothes such as tutle neck line, long sleeve, button cuffs, fastening lace, open zipper and belt of trousers gave much difficulty to the hemiplegic when dressing and undressing. 4. The most difficult motion of dressing and undressing was fastening when dressing both dress shirts and trousers. 5. There were partly significant relationship between design of clothes and ROM, muscle power, finger function of hemiplegic aged man. 6. There were partly significant relationship between the degree of difficulty in dressing and undressing motions and ROM, muscle power, finger function of hemiplegic aged man.

Purpose: This study was to determine the effects of exercise program for knee osteoarthritis on the physical fitness in elderly. The progressive exercise program included flexibility, strength, endurance, active range of motion and function activities. Methods: Nineteen subjects with osteoarthritis of the knees randomized to exercise group(n=10) or control group(n=9), but fourteen subjects completed the trial with an adherence of 70% to the intervention and 77% to the control. The physical fitness(back muscle strength, grip strength, flexibility, muscle power, agility, equilibrium) were evaluated with Helmas(Health Management System) made by Sewoo system at pre- and post- intervention. Results: The data were analysed with the two-way repeated ANOVA and paired t-test. The physical fitness had no difference among the groups and times except muscle power. Within experimental group, muscle power and agility were significantly increased between pre and post intervention, while the control group showed no change. Conclusion: Exercise program for knee osteoarthirits appear to be effective in muscle power and agility.

As of today-half a century has passed after 1945, the liberation from Japanese imperialism-it's significant to introspect our culture. On the one hand our culture has succeeded due to the peculiar history, but on the other hand it hasn't. So to speak, it has gained in Quantity but lost in Quality. There are keen, international competition and exchange in the modern culture. So the Qualitive success of modern design depends on if it had an original character or not. According to Korean rapid industrialization, technological extence, and economic growth, the export has increased greatly, but package design hasn't been match for them. Korean expoters have been meeting with cutthroat competition in world market. Under these circumstances it's very important that we have a real understand and interest in our culture, we strengthen the competitive power of home products with good package design. This is our age of not home market but world market. We live in an age when design wins, so that we have to develop the good design native to Korea. Many designers have proposed their opinions with the characteristic designs, but it has been only a fragmentary and passive method. We must seek for the new method more positively. The effective and proper method resolves itself into the following four points. First, to understand Korean history and culture. Second, to have the exact grip of this economic situation. Third, to promote the national emotion. Fourth, in conclusion, to accord the package design with them. We cannot put off this task to overcome the cultural subordination, to place Korea on a firm cultural basis in the world, and to contribute to the cultural exchange of package design.

Purpose: Complete rupture of metacarpophalangeal ulnar collateral ligament of thumb needs surgical exploration and repair, owing to the interposition of the adductor aponeurosis (Stener lesion) which interferes in healing process. We performed arthroscopic diagnosis and treatment on ulnar collateral ligament injury of thumb and evaluated it's efficiency. Materials and Methods: Arthroscopy was perfomed on 13 patients of whom injured on complete ruture of metacarpophalangeal ulnar collateral ligament. Follow-up period was over 1 year and mean age was 35.6 years old. Ulnar collateral ligament tears and Stener lesion were diagnosed and treated by arthroscopy procedure. Results were interpreted by joint instability, pinch power, grip power and range of motion on metacarpophalangeal joint of thumb. Results: We found 5 Stener lesions in 13 cases. There was no appreciable postoperative instability. Pinch and grip power were recovered to 92%, 94% of uninjured thumb respectively. Range of motion on metacarpophalangeal joint was mean $52^{\circ}$, almost equal to uninjured thumb. Conclusions: Arthroscopic treatment in metacapophalangeal ulnar collateral ligament injury of thumb is useful method that Stener lesion can be clearly comfirmed and treated. Also soft tissue injuries can be minimized, thereby early functional recovery can be expected.

The objective of this study was to compare the differences on the activity and power of the wrist flexors and extensors in subjects before the use of a wrist extension splint, after nighttime wearing of the splint, and after daytime wearing of the splint. Ten healthy male and ten healthy female students (mean: $22.4{\pm}1.2$ years old) volunteered to wear custom-made wrist splints either during the night or during the day, The hand force of the wrist flexor and extensor, and grip force were measured by PowerTrack II and Dynatron, respectively. At the same time, the activities of the wrist flexor and extensor were recorded by' surface electromyography. The maximal hand force and motor unit recruitment of the flexor carpi ulnatis (FCU) increased significantly (p<.05) when tile subjects wore the wrist splints during the daytime, but the maximal hand power of the FCU decreased with nighttime use of the splints. The maximal hand power and motor unit recruitment of the extensor carpi radialis (ECR) and the ECR/FCU ratio decreased both during nighttime and daytime use. The decrement of the ECR/FCU ratio was significant (p<.05). Wearing a wrist extension splint during nighttime led to the maintenance of a lengthened position of the wrist flexor, resulting in the wrist flexor becoming weak. Wearing a wrist extension splint during the day induced the wrist flexors to be greater. In healthy people, the imbalance between the wrist flexors and extensors may be caused by the use of a wrist extension splint. This study indicates that therapists have to consider whether a splint will be effective, as well as the wearing time, when prescribing splints to people with problems of the musculoskeletal system.

The purpose of study to know hand function in order to prevent disability or handicap. The ability to perform precise refined movements of hand is an important human function. Improvement in object manipulation is common goal of therapist. The ability to manipulate an object in the hand is need for many functional tasks, including writing, handling coins, small objects and ADL skills. Therapists have commonly used hand grip and pinch strengths as baseline measures to evaluate hand function. The patterns of grasps are precision grasp, power grasp, hook grasp, spherical grasp, sylindrical grasp, disc grasp, pinch, three point pinch and tip pinch. And the motion of in-manipulation are finger to palm translation, palm to finger, shift, simple rotation and complex rotation. The hand function are include to evaluate of ROM, sensation, muscle strength of hand. It used to evaluate of decision of effect and suppose of disability and acceptance of vocation. Good evaluation is need to pretreatment and baseline of treatment and help to evaluate of effect on treatment.
