This study is a study to recognize hand movements using a neural network for wrist rehabilitation. The rehabilitation of the hand aims to restore the function of the injured hand to the maximum and enable daily life, occupation, and hobby. It is common for a physical therapist, an occupational therapist, and a security tool maker to form a team and approach a doctor for a hand rehabilitation. However, it is very inefficient economically and temporally to find a place for treatment. In order to solve this problem, in this study, patients directly use smart devices to perform rehabilitation treatment. Using this will be very helpful in terms of cost and time. In this study, a wrist rehabilitation dataset was created by collecting data on 4 types of rehabilitation exercises from 10 persons. Hand gesture recognition was constructed using a neural network. As a result, the accuracy of 93% was obtained, and the usefulness of this system was verified.

Purpose : The giant cell tumor of tendon sheath is the second most common tumor of the hand, but recurred frequently although excision was performed. Authors analyzed and would report clinical findings and postoperative results of it. Materials and Methods : Between January 1991 and December 1998, 38 patients, 41 cases which the authors had performed excisional biopsy to the mass in the hand and diagnosed with the giant cell tumor of tendon sheath, was analyzed with age, sex, chief complaint, symptom duration, involved finger, involved tendon, frequently developed site in fingers, size, multiplicity, radiologic findings and recurrence. The mean duration of follow-up was 13.1 months (5~40 months). Results : Of 38 patients, twenty-nine were female. It is frequent in the fourth decade and mean age was 40.1 years old. The neurological compression symptom was found in 5 cases. The mean duration of symptom was 23.4 months. Flexor tendon was involved in 24 cases. The distal interphalangeal joint area in digit was involved most frequently in 20 cases. Index finger was the most common involved finger (14 cases), and long finger was the second most common (9 cases). All tumors were unilateral. The majority of patients had solitary lesion but one case had multiple lesion. In the radiologic findings, erosion or pressure indentation of bone was seen in 3 cases. All patients were operated by marginal excision. Recurrence rate was 5.1%. Conclusion : The risk factors in giant cell tumor of tendon sheath were female, forth decade, index finger, flexor tendon, and distal interphalangeal joint area. The recurrence was increased in marginal excision of recurred cases, in cases with multiple developed lesions or in multilobular lesion, so wide surgical excision is necessary to prevent recurrence.

The skin on the dorsum of the foot is a source of the reliable thin and sensory cutaneous free tissue transplantation with or without tendon, bone and joint. A composite flap with attached vascularized tendon grafts for the combined loss of skin and tendon on the dorsum of the hand and foot offers an immediate one stage solution to this problem. The flap provides a very durable innervated tissue cover for the heel of the foot and the dorsum of the hand and an osteocutaneous transfer combined with the second metatarsal. The major dorsalis pedis artery is constant in size, but the first dorsal metatarsal artery is variable in size and location. The dorsal surface of the foot receives sensory innervation through the superficial peroneal nerve and the first web through the deep peroneal nerve. Authors had performed 5 dorsalis pedis free flap transplantation in the foot and hand at Department of Orthopedic Surgery, Chonbuk National University Hospital from August 1993 through August 1997 and followed up for the period of between 19 and 67 months until March 1999. The results were as follows 1. 5 cases dorsalis pedis free flap transfer to the foot(4 cases) and the hand(1 case) were performed and the recipient was foot dorsum and heel 2 cases each and hand dorsum 1 case. 2 All of 5 cases(100%) were survived from free flap transfer and recipient artery was dorsalis pedis artery(2 cases), anterior tibial artery(1 case), posterior tibial artery(1 case) and ulnar artery(1 case) and recipient veins were 2 in number except in the hand. 3. Long term follow up of the exterior and maceration was good and sensory recovery was poor 4. Donor site was covered with full thickness skin graft obtained from one or both inguinal areas at postoperative 3rd week and skin graft was taken good and no morbidity was showed.

The purpose of this study is to investigate the effects of task-oriented activities on hand functions in patients with hand injuries. From December 2011 to October 2012, sixteen patients with hand injuries at C Hospital in Changwon, Gyeongsangnam-do, Korea were randomly divided into two groups. One group was subjected to task-oriented activity and the other to general exercise. Two groups performed each activity once a day, three times a week, for four weeks. The group with the task-oriented activities was provided with the tasks according to subject-preference based on the result of Canadian Occupational Performance Measure (COPM). To verify the effect of intervention, the following hand function measures were used: grip strength, pinch strength, and the range of opposition and abduction, Purdue pegboard test and Disabilities of the Arm, Shoulder and Hand (DASH). Both groups showed significant increase in all of the hand function measures after 4-week activities(p<.05). The task-oriented activity group was significantly different from the control group in powers for tip pinch, lateral pinch and three-jaw chuck pinch, Purdue pegboard test and DASH(p<.05) except in grip strength and the range of opposition and abduction suggesting better improvement in hand functions. This study shows that task-oriented activities improve the hand functions more effectively in patients with hand injuries.

X선은 발암성이 있는 방사선이지만 X선을 잘 다루어 셀수도 없는 인명을 구해내고 있다. 농약의 경우도 편파적인 생각으로 그 안전성을 논하는 것은 오히려 인류의 안전에 위협이 될 수 있다. 앞으로의 과학기술발전에 획기적 성과를 기대할 수도 있겠지만 지금으로서는 무농약재배로 인류 생존은 불가능하다.

Purpose: The purpose of this study was to explore relationship among pain, body image and satisfaction in hand-injured workers. Methods: Using a sample of 96 out-patient workers with hand injuries, pain, body image and satisfaction were measured by VAS and Modified Jung Keum-hee's Tennesee Self Concept Scale. Repeated measured ANOVA and a Bonferroni correction for multiple statistical testing during post hoc analyses were conducted to evaluate relationship among pain, body image and satisfaction in hand-injured workers. Result: Functional satisfaction(r=.46, p<.001) and appearance satisfaction(r=.55, p<.001) significantly increased by treatment satisfaction. Functional satisfaction(r=.35, p=.001) and appearance satisfaction(r=.31, p=.002) increased by body image. But treatment satisfaction(r=-.20, p=.049), functional satisfaction (r=-.34, p=.001) and appearance satisfaction (r=-.39, p<.001) significantly decreased by pain. Conclusion: Poor pain management was related to bad body image and treatment satisfaction. Therefore, interventions targeting at pain management are needed for hand-injured workers.

Although variable surgical methods of sympathetic nerve for palmar hyperhidrosis are curative and safe therapeutic options, they have some limitations such as compensatory sweating and anhidrosis of hand in long term satisfaction rate. Material and Method: Therefore, we tried to decrease severity of compensatory sweating and prevent excessive dryness of hand through selective division of rami communicantes of thoracic sympathetic ganglia distributed to the hands(ramicotomy). Result: In postoperative results, about half of the patients maintained humidity of hands and most of them showed no more than mild degree of compensatory sweating. Conclusion: Therefore, ramicotomy of thoracic sympathetic ganglia can be recommended as selective and physiologic surgical method for palmar hyperhidrosis.

The purpose of this study was to evaluate the relationship between shoulder pain and hand edema in stroke patient with shoulder hand syndrome. In this study, 26 hemiplegic patients with the clinical symptom and sign of shoulder hand syndrome were evaluated. Hand volume was measured by hand volumeter, and hand edema was calculated by volume difference of both hands. Shoulder pain was evaluated using VAS (visual analog scale). and spasticity of shoulder was graded by modified Ashworth scale. The relationship among three factors such as shoulder pain. hand edema and shoulder spasticity was evaluated using correlation analysis. Results through correlation analysis among three factors are as follows : 1. Correlation between shoulder pain and hand edema was not significant$(\gamma=-.028)$. 2. Correlation between shoulder spasticity and hand edema was not significant $(\gamma=-.027)$. 3. Correlation between shoulder spasticity and shoulder pain was not significant $(\gamma=-.093)$. As the result of correlation analysis. this study shows that there was no statistically significant difference between shoulder pain and hand edema.
