The purpose of this study was to evaluate isometric trunk extension strength in hemiplegic patients, and to compare that with normal subjects to find a correlation between trunk extension strength and the functional independent degree in hemiplegic patients. Fifteen hemiplegic male patients (mean age $55.2{\pm}10.2$ years) and twenty-five healthy male subjects (mean age $54.6{\pm}10.3$ years) completed isometric trunk extension. Strength was measured at 0, 12, 24, 36, 48, 60, and 72 degrees of trunk flexion. The functional independent degree was assessed by Functional Independence Measure (FIM). Mean isometric trunk extension strength was 91.2 ft-lbs, 120.7 ft-lbs, 142.3 ft-lbs, 156.4 ft-lbs, 173.5 ft-lbs, 184.1 ft-lbs, and 195.3 ft-lbs in the hemiplegic patients group, and 135.6 ft-lbs, 175.6 ft-lbs, 204.4 ft-lbs, 221.9 ft-lbs, 231.2 ft-lbs, 246.8 ft-lbs, and 259.7 ft-lbs in the normal subjects group. The values of isometric trunk extension strength had a descending linear correlation pattern from trunk flexion angle to extension angle. Trunk extension strength in hemiplegic patients was significantly lower than that of normal subjects (p<.05) but did not correlate with the FIM total score (p>.05). Therefore, the isometric trunk extension strength in hemiplegic patients was lower than that of normal subjects and did not correlate with the functional independent degree.

폐구리전선의 재활용 공정은 여러 단계의 절단공정으로 피복재로부터 구리선을 분리 후 비중선별공정으로 구리선을 회수하는 방법이 사용되고 있다. 구리세선은 이후의 재활용 공정에서 손실 등의 우려가 있어 추가적인 처리가 필요하다. 이 연구에서는 볼밀처리를 통해 구리세선의 응집체를 구성하여 손실을 방지하고자 하였다. 구리선의 응집은 구리선이 휘어져 서로 얽히는 과정에서 발생하므로 본 연구에서는 볼밀처리 후 구리전선의 굴곡도를 측정하였다. 0.5 cm와 3 cm의 구리세선을 사용하였을 때 볼의 투입과 상관없이 0.5 cm 구리세선은 휘지 않았고, 3 cm의 구리세선은 모두 응집되었다. 1 cm와 2 cm의 구리선을 사용하였을 때는 볼을 투입하였을 때 구리선의 휨 현상이 현저하였다. 2 cm의 구리세선을 사용한 실험에서 20 mm 알루미나 볼의 투입량을 증가시킴에 따라 구리선의 응집율은 점차적으로 증가하였고 30 mm 알루미나 볼을 사용하였을 때 200 ml 투입한 경우 응집율이 89.29 %로 증가한 후 볼 투입량을 증가시키면 응집율이 감소하였다. 이와 같이 구리세선을 볼밀 처리하면 구리세선의 응집체 형성이 가능하여 구리세선의 손실이 감소될 것으로 기대된다.

Objective: To examine (1) the degree of reduction of passive range of motion (PROM) on the affected side compared to that on the unaffected side and (2) the degree of increase in PROM following intra-articular corticosteroid injection (IACI) in patients with frozen shoulder. Method: The medical records of 120 patients with frozen shoulder were retrospectively reviewed. PROM of the unaffected and affected shoulder (flexion, extension, abduction, internal rotation, external rotation) was compared, and changes in PROM of the affected shoulder after a single IACI (triamcinolone 20 mg) were evaluated after 12 weeks. Results: At the time of diagnosis, PROM of the affected shoulder was most limited in external rotation, followed by internal rotation, abduction, extension, and flexion, compared to that of the unaffected shoulder. Compared to before IACI, PROM of external rotation demonstrated the greatest increase compared to all the other movements after IACI. Conclusion: Limitation in PROM of the frozen shoulder at the time of diagnosis was greatest for external rotation. Moreover, external rotation experienced the greatest improvement after IACI. Our findings should help to further clarify the clinical characteristics of frozen shoulder, aid in its diagnosis, and allow the prediction of the effects of IACI.

The active-knee-extension (AKE) test has been used to measure hamstring muscle length. The traditional AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip fixed by straps, while the stabilized AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip stabilized using a pressure biofeedback unit providing lumbopelvic stabilization. The purpose of this study was to determine test-retest reliability of the traditional AKE test and stabilized AKE test. Twenty healthy adults participated in the study. The popliteal angles were measured with a digital inclinometer during each test. To assess the test-retest reliability between the 2 test sessions, intraclass correlation coefficients (ICCs) were calculated. The intrasubject coefficient of variation ($CV_{intra}$) was also calculated. To compare the traditional and stabilized AKE tests for changes in pressure, paired t-tests were applied. The results of this study were as follows: 1) ICCs(3,1) value for test-retest reliability was .96 in the traditional AKE test, and was .98 in the stabilized AKE test. 2) The maximal $CV_{intra}$ was 33.7% in the traditional AKE test and 15.7% in the stabilized AKE test. 3) Differences of $6.1{\pm}2.1$ mmHg in pressure were measured in the traditional AKE test, and differences of $1.2{\pm}1.0$ mmHg in pressure were measured in the stabilized AKE test. The results show the traditional and stabilized AKE test to be highly reliable, with test-retest reliability. However, the stabilized AKE test represented less variation and more stabilization than the traditional AKE test. Further study is needed to measure the inter-rater reliability of the stabilized AKE test for generalization and clinical application.

Purpose: The purpose of this study was to explain the effects of upper extremity exercise program on hemiplegic stroke patients. Method: The research was designed by a non-equivalent pretest-posttest way. The data were collected from February to August 2003 at a community health center located in Seoul. The study subjects were a conveniently selected group of 27 hemiplegic patients. The subjects were divided into two groups, the experimental group and the control group. 14 subjects were assigned to the experimental group in which the subjects did the upper extremity exercise training for 2 hours once a week during four weeks, while 13 subjects were assigned to the control group. The outcomes were evaluated on the basis of the upper extremity motor ability(hand power, pinch power, upper extremity ROMs), amount of motor use and the degree of depression. Result: 1. After treatment, the motor abilities of the affected upper extremity(hand power, pinch power, ROMs of wrist flexion/extension, shoulder extension) were significantly different between the two groups. However, there were no significant differences in elbow and shoulder flexion between experimental and control group. 2. After treatment, amount of motor use of affected upper extremity were significantly different between the two groups. 3. After treatment, the degree of depression were significantly different between the two groups. Conclusion: In considering these results, the upper extremity exercise program could be effective for hemiplegic patients by improving the function of their upper extremity. Long-term studies are needed to determine the effects of upper extremity exercise program.

Purpose: This study conducted quantitative sensory test and nociceptive flexion reflex(NFR) measurement to examine degree of pain depending on polarity of high voltage pulsed current(HVPC) of hyperalgesia site in hyperalgesia rat by local thermal injury. mechanical pain threshold, thermal pain threshold and root mean square of NFR were measured. Methods: This study was conducted with control group I of hyperalgesia rat at hind paw by thermal injury and experimental groups divided into cathodal HVPC group II, anodal HVPC group III and alternate HVPC group IV. It measured pain threshold and root mean square(RMS) of NFR and obtained the following results. Results: Mechanical pain threshold of hyperalgeisa site was significantly increased at groups II, III and IV applying HVPC group compared to control group, but there was no difference among HVPC groups. Thermal pain threshold of hyperalgesia site showed a significant increase in group II. Group III showed significant difference after 4 days of hyperalgesia. RMS of NFR at hyperalgeisa site was significantly reduced in group II after 2 days of hyperalgesia. Group III showed significant decrease after 5 and 6 days of hyperalgesia. Conclusion: Consequently it was found that application of HVPC of hyperalgesia site increased pain threshold at hyperalgesia site by mechanical stimuli and thermal stimuli. NFR by electrical stimuli was similar to pain threshold by mechanical stimuli. Effects by polarity of HVPC showed the greatest reduction of hyperalgesia when cathodal electrode was used.

Purpose : The purpose of this study was to investigate the effect of tensor fasciae latae length on the rotation of pelvis during one leg stance. Methods : 41 healthy adults participated in this study. The movement of the pelvis and trunk was measured using 3-dimensional motion analyzer, during one leg stance. The movement of the pelvis and trunk was collected lateral shift, rotation, side bending, and flexion-extension. Tensor fasciae latae length of subjects was measured in sidelying positon with neutral position of hip joint and flexion $90^{\circ}$ of knee. Also, the range of motion of hip exteral and interal rotaion were measured in prone position wih lexion $90^{\circ}$ of knee. The subjects were separated 2 groups that more pelvic rotation group(n=15) and less pelvic rotation group(n=15) according to the degree of pelvic rotation. Results : The more pelvic rotation group was showed significantly higher in the ROM of hip external rotation than less pelvic rotation group(p<0.05). The difference of tensor fasciae latae length not showed significant difference between groups. During one leg stance, The movement of the shifting and flexion-extension of trunk and pelvis were not showed significant difference. But the side bending and the rotation of pelvis and trunk showed significant difference between groups. Conclusion : The difference of tensor fasciae latae length not showed significantly in more pelvic rotation group and less pelvic rotation group. But, this study suggests that the pelvis instability brings the instability of the trunk during one leg stance.
