Thumb adduction is an abnormal pattern typically noted in children with spastic cerebral palsy. This abnormal pattern can limit hand function, specifically in the type and quality of prehension pattern used and in the coordination of release. This ABAB single-subject research was designed to examine the effects of short thumb opponens splint on hand function in cerebral palsy. The subject was a 4 years and 8 months old boy with right upper extremity spasticity. The child was fitted with a short thumb opponens splint, which was worn for 8 hours per day during the daytime. Two different measures were used: (a) prehension component scores; (b) Bruininks-Oseretsky test of motor proficiency. Data was collected three times a week for 10 weeks. Visual analysis of data indicate that after the application of a short thumb opponens splint, improvements were noted in the prehension pattern and fine motor functional task. The results of this study suggest that short thumb opponens splint may prove efficaciousness in the treatment of the child with cerebral palsy.

The purpose of this case study was to introduce a myoelectric hand prosthesis for upper extremity amputee and prosthetic training program. Limb loss can result from disease, injury, or congenital causes. Trauma has been increasingly important role as the cause of amputaion in young, vigorous, and otherwise healthy individuals. The higher the level of amputation the greater the functional loss of the part, and the more the amputee must depend on the prostheis for fuction and cosmesis. Myoelectrical control of prostheses is a recent development and has been steadily gaining in clinical use over the past 20 years. Such a prosthesis uses signals from muscle contraction within the stump to activate a battery driven moter that operates specific component fuctions of the prosthesis. This twenty years old male case was operated a right above-elbow amputation due to tracffic accident and admitted to Yonsei Rehabilitaion hospital for the preprosthetic and prosthetic training. The case was able to successfully complete his myoelectric hand prosthesis training in the February of 1995.

Purpose: The purpose of this study was to examine the effects of a 16-week Self-help Tai Chi for Arthritis (SHTC) combined with health education for Korean American older women. Methods: This research was a designed quasiexperimental pre-posttest. Forty one women aged 55~79 were recruited 20 in SHTC group 21 in control group and, but twelve in SHTC group and thirteen in control group were left after 16 weeks. SHTC group was educated for 1 hour health education and 1hour TCA, once a week during 16 wks. Measurements for comparison were taken three times, at baseline, 8 wks and 16wks. The effect were evaluated with self-efficacy, shoulder flexibility, back flexibility, both hand grip strength and standing balance with closed eyes. Results: All variables except for left hand grip strength at baseline had significant homogeneity between both groups. After 16 weeks intervention, there was a significant interaction effect of time and group on right hand grip strength by repeated measure of ANOVA (F=3.398, p=.044). No significant interaction effects were found on self-efficacy, shoulder and back flexibility, left hand grip strength and standing balance with closed eyes. Conclusion: I can suggest this self-help Tai Chi program may be effective partially, but further research is needed to establish the best times and periods to intervene for a better effect.

Objective: The aim of this study is to investigate the association between dance experience and smoothness of hand trajectory during dance by using three jerk-based quantitative methods (integrated squared jerk, mean squared jerk, and dimensionless jerk). Methods: Eleven Korean traditional dancers whose experience of dancing ranged from 5 years to 20 years participated in this study. Dancers performed the Taeguksun motion in Korea traditional dance. Six infrared cameras were used to capture the movement of the hands of the dancers. The smoothness of hand movement was calculated using three jerk-based methods. Results: With regard to the smoothness of the right hand, dance experience was significantly correlated with dimensionless jerk (r=0.656, p=0.028), while dance experience was not significantly correlated with integrated squared jerk (r=0.581, p=0.552) and mean squared jerk. With regard to the smoothness of the left hand, there was no correlation between dance experience and any of the three jerk values. Conclusion: Our results showed that individuals with more dance experience performed the task more smoothly. This study suggests that dimensionless jerk should be used as a predictor for smoothness in dance movement. Thus, our results support the idea that smoothness is an aspect of movement quantity distinct from speed and distance.

When the scrotal sac is entirely debrided following a Fournier gangrene, testes exposure poses unique challenges for the reconstructive surgeon. Despite the anterolateral thigh (ALT) flap is considered a workhorse in such context, aesthetic results are often suboptimal because of the lack of natural ptosis and patchwork appearance. We describe the use of a super-thin pedicled ALT flap for total scrotal reconstruction, modified according to a peculiar flap design and inset technique. A 42-year-old man was referred to our department for delayed total scrotal reconstruction 8 months after a Fournier gangrene extensive debridement. A super-thin pedicled ALT flap from the right thigh was designed: in the central portion of the ALT, a lateral skin paddle extension was marked to guarantee adequate posterior anchorage during insetting and ptosis of the scrotal sac. This particular flap arrangement has inspired the name "sombrero" as the shape is akin to the famous hat. No secondary refinements were needed, and the patient showed satisfying aesthetic and functional results at 12 months' follow-up. The ALT flap design "sombrero" modification proposed in this article can improve scrotum cosmesis and patient satisfaction in a single-stage single-flap procedure.

In the past decades there has been a growth of interest in the use of stellate ganglion block (SGB) as part of the diagnosis and therapy for the disease of the head, neck and upper extremities. For the evaluation of changes in hemodynamics and temperature of the affected extremity after the SGB, unilateral SGB (either right or left) was performed by local injection of 10 ml of 1% lidocaine without epinephrine in 45 patients (right side SGB: 25, left side SGB: 20) with various diseases. Systolic and diastolic blood pressure, pulse rate and skin temperature of the ipsilateral hand were studied before and 1, 2, 3, 4, 5, 10, 15, 30 and 60 minutes after the block. The results were as follows: 1) Changes of blood pressure: Systolic and distolic blood pressure after either right or left side SGB showed no statistically significant change. 2) Changes of pulse rate: While the left side SGB showed a mild decrease without statistical significance, the right side SGB showed a statistically significant decrease at 30 and 60 minutes after the block (p<0.05). 3) Changes of skin temperature of the blocked hand: Either side SGB produced a gradual increase in temperature with time and showed statistical significance from 10 minutes in the left side block (p<0.01), and a from 10 minutes after the block in the right side (p<0.01). Both sides SGB showed a maximal increase at 30 minutes after the block and a small decrease at 60 minutes after the block compared to the 30 minutes value. 4) Despite the successful SGB. 4 of 45 patients failed to produce a significant increase in skin temperature on the affected upper extremity. In conclusion, unilateral SGB with 1% lidocaine at the 6th cervical vertebral level is a safe method for use on an outpatient basis, and an increase in skin temperature in the affected upper extremity is necessary to confirm the successful therapeutic effect on disease of the upper extremity.

OBJECTIVES: This study was performed to find out static two-point discrimination (TPD) in fingertips. METHODS: This was a cross-section, measure study of static two-point discrimination involving healthy young adults. Measure was completed by 48 college students in Andong Science College from June 1 to 12, 2004. The minimal distance at which two-points could be discriminated was measured from thumb to little finger. RESULTS: For dermatomal regions of the fingertip, mean values ranged from 3.3mm to 4.9mm (thumb 3.6mm, index finger 3.3mm, middle finger 3.8mm, ring finger 4.2mm, and little finger 4.7mm in the left hand; thumb 3.7mm, index 3.5mm, middle 4.0mm, ring 4.3mm, and little 4.9mm in the right hand). A significant difference in discrimination ability was found between men and women, 3.5mm for women showed a greater sensitivity than 4.1mm for men in the left middle fingertip(p=0.0109), also 3.9mm for women showed a greater accuracy than 4.5mm for men in the left ring fingertip(p=0.0388). In the right index fingertip, women (3.1mm) have a narrow distance than men (3.6mm)(p=0.0329). The minimal distance of TPD was found a significant difference between 20 and 30 years in age. 4mm for 30 years showed a greater distance than 3.5mm for 20 years in the left thumb fingertip(p=0.0354), also, 3.8mm for 30 years showed a greater distance than 3.2mm for 20 years in the left index fingertip(p=0.0174), and 4.3mm for 30 years showed a greater distance than 3.7mm for 20 years in the left middle fingertip(p=0.0444). In the right index fingertip, 20 years (3.2mm) had also a narrow distance than 30 years (4.1mm)(p=0.0020), 20 years (3.9mm) showed a narrow distance than 30 years (4.6mm) in the right middle fingertip(p=0.0124), and 20 years (4.1mm) showed a greater sensitivity than 30 years (5.0mm) in the right ring fingertip(p=0.0070). CONCLUSIONS: Our results suggest that distance of TPD in the both index fingertips for 20 years women was significantly narrowed.

The purpose of this study is helps to make full use for perfect performance by grasping the defects of Tichonkich motion performed by athlete CSM For this, the study analyzed kinematical variables through Tichonkich motions performed at the first selection competition(1st trial) and final selection competition(2nd trial) for the dispatch to the 28th Athens Olympic Games using the three-dimensional cinematographical method with a high-speed video camera, and obtained the following results. 1. During Tichonkich motion, the execution time of up swing and the right hand moving to the left bar was shorter in the 2nd trial than the 1st one, while the execution time of down swing, the support of the left bar and the right hand moving to the right bar was longer in the 2nd trial than the 1st trial. 2. The horizontal position of COG in the 2nd trial was -35cm in the 1st stage, 42cm in the 3rd stage and 29cm in the 4th stage, that is, it showed a great swing focused on the circular movement compared to the 1st trial, while the vertical position of COG was -59cm in the 2nd stage, that is, it showed a small swing focused on a up and down movement. Also the 5th stage vertical position was 98cm, and the 6th stage vertical position was 95cm in the 2nd trial which were higher than those of the 1st trial, so it has provided magnificence required in the modern gymnastics. 3. And it was indicated that the horizontal velocity at the down swing phase proceeded forward more rapidly in the 2nd trial than that in the 1st trial, and the reverse ascent made a rapid vertical rise lessening left and right velocity change. And in the 5th stage, the 2nd trial was kept very slower in horizontal, vertical and left and right velocity that in the 1st trial, so it reached a handstand with leisurely movement. 4. In the 2nd trial, shoulder joint of the 1st, 2nd, 3rd stages kept a larger angle than that in the 1st trial, that is, it made a great swing while in the 1st trial, it showed a swing movement dependent on kick movement by the flexion and extension of hip joint. Also in the 2nd trial, the body formed a vertical posture with both hands supporting the left bar and hip joint was kept larger as $198^{\circ}$ and $190^{\circ}$ in the 5th and 6th stage than that in the 1st trial, so it made a handstand with the body uprightly stretched out, and magnificent and stable movement.

The purpose of this study was to explore the changes of values in Korea focused on the period from liberation in 1945 to industrialization in the late 1970s. Those periods classified into 'Transitional Era' and 'Industrial Era' based on historical events significantly influenced the changes of value system of Korean people or Korean society. In this study, not only main values and right people for society but also the way of changing value system in those periods were suggested by investigating factors of politics, economy and society. The results are as follows : First, main values and right people for society on each period were as follows : In Transitional Era, main values were manners and social norms, and right people for this period were practical intellectuals pursuing the principle of action-oriented truth-and- knowledge-seeking. In Industrial Era, on the other hand, main values were sincerity, diligence, self-help and collaboration, and right people for this period were skilled man having occupational ability which was essential for economic development. Second, lasting value in Transitional Era and Industrial Era was patriotism. The patriotism in early Transitional Era was appealed to nation and people because of the collapse of ruling system and the absence of leaders, however, the patriotism changed to loyalty towards a national leader or seniors after the formation of new ruling system by building nation and electing a leader. On the other hand, the patriotism of Industrial Era was distinctly defined purpose for carrying out national economic policy and overwhelming Democratic People's Republic of Korea with anti-communist spirit and unification will.

Purpose: Thumb reconstruction plays most important role in hand injuries because total loss of a thumb constitutes about 40% disability in the hand. The reconstruction can be accomplished by pollicization, free toe-to-thumb transfer, wrap around procedure and lengthening extraction. However, we sometimes need consecutive or double free flaps in the reconstruction of mutilating hand injuries. Methods: We reconstructed a mutilating hand injury in a 54-years old man. Because of severe crushing injury of right thumb and index fingers, we reconstructed a thumb with pollicization using nearly amputated middle finger. Although it survived completely, the adjacent soft tissues which had been covered by fillet flap from the space past was necrosed on 1 month. We debrided the necrotic tissues and covered it with anteromedial thigh perforator free flap consecutively because he had an anatomical variation in branches of lateral femoral circumflex artery. Results: He had an uneventful postoperative course without any complication such as infection, dehiscence and flap necrosis. Three months later, he had undergone tenolysis and defatting procedure of flap site. He recovered the some amount of grip function and was happy with the result. Conclusion: In severe hand trauma including thumb amputation, thumb reconstruction using pollicization and perforator free flap could be an alternative option. It provides minimal donor site morbidity and an acceptable functional result.
