  • The purpose of the present study was to the investigate the effect of aging in men and women on muscle strength of knee extensor and flexors by using the cybex 6000 isokinetic dynamometer. A total of 100 volunteers participated in this study and were divided into five groups according to their chronological age as follows: 20s, 30s, 40s, 50s, 60s, 10 men and 10 women in each decade respectively. Isokinetic ($60^{\circ}{\cdot}s-l$) knee extensor and flexor peak torque, peak torque to body weight ratio, opposing muscles(flexor/extensor) peak torque ratio, deficit of peak torque between dominant and non-dominant were measured. The results obtained were as follows: 1) In men, While the aged increased. the peak torque of the knee flexor and extensor statistically sig nificant decreased in the dominant and non-dominant side. 2) In women, Statistically significant difference of knee extensor peak torque was found as the aged increased in the dominant and non-dominant side, but significant difference of knee flexor peak torque did not that. 3) In men, No significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the non-dominant side, but statistically significant difference in the peak torque of knee flexor to body weight weight ratio was found as the aged increased in the dominant side. 4) In women. No significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the dominant side, but statistically significant difference in the peak torque of knee flexor to body weight ratio was found as the aged increased in the non-dominant side. 5) In men and women, While the aged increased, statistically significant difference was found the dominant and non-dominant side in the peak torque of knee extensor to body weight ratio. 6) Peak torque of hamstring to quadriceps ratio of dominant and non-dominant side in men and women were not significantly different as the age increases. 7) Mean deficit of peak torque between dominant and non-dominant side in men and women were not significantly different as the age increases. From these results we conclude a proper exercise program is need before 50s decade to preserve in muscle strength of knee flexors and extensors.

  • 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.

  • 장무지 신전건의 폐쇄성 파열은 흔하지 않으며 드물게 보고되는 손상이다. 저자들은 연습 중 다른 선수의 정강이에 부딪힌 후 발생한 장무지 신전건 폐쇄성 파열에 대해 보고하려 한다. 환자는 6년 넘게 하루에 6시간 이상씩 연습을 해온 태권도 선수로서 발등의 반복적인 타격으로 인해 장무지 신전건의 퇴행성 변화가 일어났던 것으로 추정된다. 수술시에 손상된 건의 양끝은 끌어당겨 봉합할 수 없는 상태였기 때문에 재건술을 시행하였다. 잘려진 건의 원위부를 종축을 따라 반으로 나누어 절반은 파열부 사이의 반흔조직을 이용하여 근위부의 건과 연결하였으며, 나머지 절반은 건고정술(tenodesis)로 단무지 신전건에 부착시켰다. 환자는 수술 후 6 개월에 만족스러운 관절운동범위를 보였고, 수술 전 수준의 운동에 복귀할 수 있었다.

  • Purpose: This study was conducted in order to analyze the effect of proprioceptive neuromuscular facilitation lower extremity pattern on muscular strength and flexibility in an aquatic environment. Methods: Ten members of the experimental group and 10 members of the control group were randomly selected from 20 college students who are in their 20s. Bilateral symmetry pattern among proprioceptive neuromuscular facilitation lower extremity patterns was applied in an aquatic environment in the experimental group three times per week for a period of six weeks, and a set consisted of 10 times, which was repeated 10 times. On the other hand, subjects in the control group did not receive any treatment while maintaining daily life. Muscular strength was measured using a dynamometer and electromyogram system for maximum voluntary isometric contraction of hip flexor, hip extensor, knee flexor, and knee extensor. Cervical flexibility was measured using cervical range of motion instrument for cervical flexion, rotation, and lateral flexion. Lumbar flexibility was measured using back range of motion instrument II for lumbar flexion. Results: For the experimental group, significance was observed for hip flexor, extensor, knee flexor, extensor, cervical flexion, rotation, lateral flexion, and lumbar flexion. For the control group, no significance was observed for any other variables except for cervical flexion. As a result of observation of difference between the two groups, relatively high significance was observed in the experimental group, compared with the control group. Conclusion: In conclusion, proprioceptive neuromuscular facilitation lower extremity pattern had a positive effect on muscular strength and flexibility in an aquatic environment.

  • Purpose: This study evaluated the validity of measuring paravertebral muscle function with 3D-NEWTON (Hanmed, Korea) by assessing the correlation between Biodex (Biodex, USA) and surface electromyography (EMG). Methods: Nineteen healthy adults participated. The function of their paravertebral muscle was measured in three ways. Maximum endurance time was measured in seconds when 3D-NEWTON was inclined forward for assessing extensor function, and inclined backward for assessing flexor function. Using surface EMG, maximum muscle activity was obtained from the eractor spinae and rectus abdominis during the 3D-NEWTON measurement. Maximum muscle activity was the mean activity from 10 seconds when the root mean squared firing data was highest. Through Biodex the peak torques of the extensor and flexor were measured during isometric exercises. The Spearman correlation coefficiencts from 3D-NEWTON, surface EMG, and Biodex were calculated. Results: The data from surface EMG and Biodex were statistically correlated when measured for flexor function, but less so for extensor function. In the case of 3D-NEWTON, the correlation coefficient with Biodex was 0.50 (p=0.05), while the coefficient with surface EMG was 0.53 (p=0.02) when measured for extensor function. Similarly, the correlation coefficienct with Biodex was 0.60 (p=0.01), while the surface EMG was 0.51 (p=0.03) for flexor function. Conclusion: 3D-NEWTON was a useful method for measuring paravertebral muscle function and can give helpful information for treating people with diseases associated with the lumbar spine.
