High-pressure (HP) injection injury to the upper extremity often causes a very serious clinical problem, leading to poor outcomes, including amputation, so that a true surgical emergency is required. The outcomes can be improved with emergent wide surgical debridement. However the diagnosis of these injuries is often delayed due to underestimated evaluation at first appearance and lack of common knowledge of the seriousness of this injury. The type and pressure of the infecting material is an important factor in prognosis and organic solvents infected pressure injury can cause poor outcome and increased amputation rate. In this case, we report on reconstruction of HP oil-based paint injection injuries of the finger using T-shaped pedicles and multiple venous anastomoses. In this concept, arterial flow can be maintained by the reverse flow of distal anastomosis when there is difficulty with the proximal anastomosis. And venous flow can be preserved by deep and superficial vein anastomosis. This concept has various advantages including preserving patency of the pedicle in chronic vasculopathy or trauma cases and maintaining the arterial flow by the reverse flow of distal anastomosis and can improve the free flap survival by a two vascular anastomosis system.

Objective : The purpose of this study was to examine the correlation between handwriting skills and praxis. Method : Participants consisted of 50 normal children who were the second-grade students at an A elementary school in Kim-hae. They didn't have a visual dysfunction, an auditory dysfunction, and a disease or an injury in arms and hands. They could follow examiners' directions properly. They were administered the Postural Praxis and the Praxis on Verbal Command of the Sensory Integration and Praxis Tests(SIPT)(Ayres, 2000) and the handwriting skill test which was made with reference to foreign literatures. It was conducted from October 19, 2004 to December 17, 2004. The data were analyzed with non-paired t-test, ANOVA, and Pearson correlation coefficient. Results : 1. Total handwriting score and praxis according to gender of children showed the statistically significant differences(p<0.05). 2. Total handwriting score correlated with praxis(p<0.05) and handwriting speed did not correlate with praxis. 3. Postural Praxis and Praxis on Verbal Command according to handwriting groups showed the statistically significant differences(p<0.05). 4. Among the standards of the handwriting skill test, accuracy of letter form, identity of letter size, spacing between letters and words, placing text on lines, error existence, and letter out of regular square correlated with the Postural Praxis(p<0.05), and accuracy of letter form, identity of letter size, and placing text on lines correlated with the Praxis on Verbal Command(p<0.05). Conclusions : The correlation between handwriting skills and praxis will help occupational therapists to provide fundamental and various treatment programs for children who are referred for the poor handwriting. But more studies in handwriting skills and praxis are necessary to decide which component of handwriting skills is related to praxis.

In this study the physiological significance of the upper and lower body on thermoregulation and sensation are examined. Experiments were carried out on 4 females in a climatic chamber conditioned at $25\pm1^{circ}C, 50\pm5%$ R.H.. Before the measurements, subjects were exposed to 3 types of enviromental temperature: 1) $25\pm1^{\circ}C$ for 60 min.(ST), 2) $25^{\circ}C$\rightarrow35^{circ}C\rightarrow25^{\circ}C$ for about 40 min.(HT), 3) $25^{\circ}C$\rightarrow15^{circ}C\rightarrow25^{\circ}C$ for about 40 min.(LT) covering the upper body (U) or lower body (L) with garments. 1) $T_{re}$ was significantly higher in L than in U only in 57 condition. $T_{sk}$ and Temp. under the clothing were higher in U than in L in all three conditions. Thermal sensation was warmer in U than in L, and comport sensation was most comfortable in HT condition. 2) When the upper or lower body was covered or exposed, the mean skin temperature of the upper body was higher than that of the lower body. Following covering and uncovering the same area, the changes in skin temperature were greater in the upper body than in lower body, and covering the upper body produced a greater difference of skin temperature between body and lower body than covering the lower body. 3) In all environmental conditions, when the upper body was uncovered, the skin temperatures of the chest, upper arms and forearms dropped to a considerable degree, and when the lower body was uncovered, skin temperatures of the legs showed the same pattern. On the other hand, skin temperature of the thinghs showed only little change in all cases except forehead and back uncovered or covered in two clothing types.
Background: The purpose of this study is to assess the range of shoulder motion using an indirect evaluation method without physical examinations of patients based on questionnaires regarding several specific arm postures referenced by patient's own body parts. Methods: Nine criteria of specific shoulder motion including 4 forward flexion, 2 external rotation, and 3 internal rotation were decided as reference position which can represent a certain shoulder motion. Flexion contains postures such as lifting arm to waist-height, shoulder-height, eye-height, and raising arm above head with arm touching ears. External rotation comprises grasping ears and placing hands on back of the head. Vertebral height in internal rotation is determined by calculating the samples' motions, which are holding on to trouser belts, opposite-elbow, and scapula. These postures are included in questionnaires for patients to evaluate the validity and effectiveness of this indirect method. Results: The range of flexion was $77^{\circ}$ ($60^{\circ}$ to $100^{\circ}$), $96^{\circ}$ ($87^{\circ}$ to $115^{\circ}$), $135^{\circ}$ ($115^{\circ}$ to $150^{\circ}$), and $167^{\circ}$ ($150^{\circ}$ to $175^{\circ}$) when arms go up to waist, shoulder, eye, and high vertically. Range of external rotation was $39.6^{\circ}$ ($30^{\circ}$ to $50^{\circ}$) when grasping ears and $69.2^{\circ}$ ($60^{\circ}$ to $80^{\circ}$) with the hands on the back of the head. Range of internal rotation was L4 when placing trouser belts, T12 for holding opposite elbow, and T9 for reaching scapula. The mismatch rates of flexion, external rotation, and internal rotation were 11.6%, 9.6%, and 7.8%. Conclusions: The range of shoulder motion using this method is expected to be applied to an established shoulder scoring system which included shoulder motion evaluation item.

The ACL(Anterior cruciate ligament) is the smallest of the four main ligaments of the knee, but it is the primary stabilizer. Injuries have a tendency to occur when the foot is firmly planted and the knee is twisted. Any sports that requires acceleration, change of direction and deceleration can increase the chances of suffering an ACL tear. The incidence of severe knee sprains that involve the ACL are at an all-time high. Since 1980, the number of these injuries have increased at least three-fold. Although the rate of increase has been much less dramatic since the middle 1980s, even the ultra-modem releasable ski binding has not been able to start reducing the incidence of ACL injuries. An ACL injury prevention program developed for downhill skiers by the Vermont Safety Research group emphasized increasing awareness of situations that can potentially result in an ACL injury and pre-planning strategies if events, leading to these situations, begin to fall in place. As part of the above study by Ettlinger et al., an educational prevent program was developed to teach these principles and thus reduce the rate of serious knee injuries. Four thousand instructors and patrol at 20 ski resorts who received the training had a 62% decline in serious knee injuries compared to a similar group that did not receive this training. Whenever you fall, try not to fully straighten your legs. Don't try to get up until you've stopped sliding(unless you are try to avoid an obstacle or other skier). When you're down, stay down. And don't land on your hand. So, if you feel yourself falling: arms forward, ski plates together, hands over knee. Then you will be able to save your ACL.
Shoulder hand syndrome is characterized by pain, vasomotor instability, and tenderness, mainly in the distal upper extremity. The pathophysiologic mechanism of this syndrome is not yet proved. The purpose of this study is to evaluate the usefulness of thermographic imaging on shoulder hand syndrome after stroke for early diagnosis and its clinical pattern analysis including acupuncture and electroacupuncture therapy. This study was performed from June to September in 1996 on 46 stroke patients who were admitted at Oriental hospital of Kyung Hee Medical Center. The study group were 23 patients with shoulder hand syndrome. The control group were 23 patients without shoulder hand syndrome. Skin temperatures on the both upper extremities were measured by Digital Infrared Thermographic Imaging(D.I.T.I.) before the study and 3 weeks later again. The results were as follows; 1. The shoulder hand syndrome group were significantly more restricted in shoulder passive range of motion than the control group. 2. The shoulder hand syndrome group showed significant temperature difference of both dorsal hands. 3. The electroacupunture therapy group were significantly more improved on the temperature difference of both dorsal hands than acupuncture therapy group in 3 weeks later. 4. Both posterior arms showed the biggest temperature difference from 11 to 30 days in shoulder hand syndrome group. 5. The lesser passive ROM(range of motion) of shoulder group showed significantly increased temperature difference of both hands. The above results show that measurement of shoulder passive range of motion and D.I.T.I. is a useful method for early diagnosis on shoulder hand syndrome and its clinical pattern analysis including evaluation of acupuncture and electroacupuncture therapy. Continuous study will be needed for more clinical application and evaluation on shoulder hand syndrome.

Neurocutaneous melanosis is a rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign pigment cell tumors of the leptomeninges. Neurocutaneous melanosis is thought to represent an error in the morphogenesis of embryonal neuroectoderm. We experienced a neonate who presented with giant, dark colored pigmented nevi covering chest, abdomen, neck and arms, with satellite lesions. Magnetic resonance image showed a nodular hyperintense lesion in the amygdala of the right temporal lobe, and T1-weighted images showed hyperintensities in the adjacent leptomeninges. We report a rare case of neurocutaneous melanosis with a brief review of related literature.

The purpose of this study was to compare the balance ability at different foot positions using K A T 2000 (Berg, Inc, vista, CA.1994). Thirty (male 15, female 15) normal subjects participated in this study. All subjects were tested at a one leg position or a two leg position that were toe-in $25^{\circ}$, toe-out $25^{\circ}$, and $45^{\circ}$. The starting position was where the subject crossed their arms across the chest and flexed knees slightily. The results of each test were displayed on a screen in a score format, which indicated balance index. These collected data were analyzed by using one way ANOVA, and t-test. The results of this study were as follows: When changing the angle of the foot in the one-foot and two-foot standing positions, there was no statistically significant difference, but the balance performance with the foot rotated by $25^{\circ}$ was better than that with the foot rotated by $45^{\circ}$. When changing the direction of the foot in the one-foot and two-foot standing positions, there was no statistically significant difference, but the balance performance with the foot rotated laterally was better - except for the case when the foot was medially rotated by $25^{\circ}$ in the right-foot static standing position. When the feet were medially rotated by $25^{\circ}$ in the two-foot static standing position, and were medially rotated by $25^{\circ}$ and $45^{\circ}$ in the one-foot static standing position, the balance performance of females was better than that of males. In this study, it was found that the balance performance of the subjects changed when the position of the foot was shifted on an unstable base of support. However, there was little correlation between balance performance and the height, weight and foot length of the subjects. It is necessary to conduct a follow-up study targeting various age groups and those with various diseases using an unstable platform or applying different physical or visual conditions, such as the length of the legs. Physical therapists need to consider the position of the foot in clinical settings for a better balance training or assessment.

Objective: The aim of this finite element study was to clarify the mechanics of tooth movement in palatal en-masse retraction of segmented maxillary anterior teeth by using anchor screws and lever arms. Methods: A three-dimensional finite element method was used to simulate overall orthodontic tooth movements. The line of action of the force was varied by changing both the lever arm height and anchor screw position. Results: When the line of action of the force passed through the center of resistance (CR), the anterior teeth showed translation. However, when the line of action was not perpendicular to the long axis of the anterior teeth, the anterior teeth moved bodily with an unexpected intrusion even though the force was transmitted horizontally. To move the anterior teeth bodily without intrusion and extrusion, a downward force passing through the CR was necessary. When the line of action of the force passed apical to the CR, the anterior teeth tipped counterclockwise during retraction, and when the line of action of the force passed coronal to the CR, the anterior teeth tipped clockwise during retraction. Conclusions: The movement pattern of the anterior teeth changed depending on the combination of lever arm height and anchor screw position. However, this pattern may be unpredictable in clinical settings because the movement direction is not always equal to the force direction.

Background: This study investigated the effect of robot-assisted arm training on muscle activity of arm and weight bearing in stroke patients. Methods: The study subjects were selected 20 stroke patients who met the selection criteria. 10 people in the robot-assisted arm training group and 10 people in the task-oriented arm training group were randomly assigned. The experimental group performed robot-assisted arm training, and the control group performed task-oriented arm training for 6 weeks, 5 days a week, 30 minutes a day. The measurement tools included surface electromyography and smart insole system. Data were analyzed using independent sample t-test and the paired sample t-test. Results: Comparing the muscle activity of arm within the group, the experimental group and the control group showed significant differences in muscle activity in the biceps brachii, triceps brachii, anterior deltoid, upper trapezius, middle trapezius, and lower trapezius. Comparing the muscle activity of arms between the groups, the experimental group showed significant difference in all muscle activity of arm compared to the control group. Comparing the weight bearing within the groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings and there were significant differences in anterior and posterior weight bearing. The control group showed significant difference only in the non-affected side weight bearing. Comparing the weight bearings between groups, the experimental group showed significant difference in the affected side and non-affected side weight bearings compared to the control group. Conclusion: This study confirmed that robot-assisted arm training applied to stroke patients for 6 weeks significantly improved muscle activity of arm and weight bearing. Based on these results, it is considered that robot-assisted arm training can be a useful treatment in clinical practice to improve the kinematic variables in chronic stroke patients.
