경비관절은 문헌적으로나 임상적으로 소홀히 다루는 관절로써 알려져 왔다. 몇몇 연구자들에 의해 생역학적 원리와 병리학적인 무제가 정립되었고, 평가방법 및 정형도수적 치료방법 등이 개발되어 왔다. 무릎과 족관절부의 병변은 항상 경비관절에 문제를 야기시킬 수 있다는 것을 전제로 평가에서 포함하여 다루어져야 한다. 경비관절에서 유발되는 질환은 대개 정형도수적 치료방법이 매루 효과적으로 적용될 수 있다고 사료된다.

Objectives : This study was to investigate the relationship analysis in VDT(visual display terminal) of work hours. Methods : Questionnaires were completed by 41 women in VDT operations. The information was used to estimate multiple regression for the VDT of work hours related factors association. Results : The prevalence of the VDT of work hours was significantly higher in the shoulder which followed by the neck, the hand and fingers, the arms, the lowback, the back. The VDT of work hours decreased with aging. The VDT of work hours increased with work duration, single, lower among habitual exercise. The desk height, the seat pan height, the posture on the sitting, the elbow angle all did not meet the recommended criteria. Conclusions : Data from this study support a statistically significant association with satisfaction for occupation.

The purpose of this study was to investigate relationship of lumbar extensor muscle power & spinal column curve for old female patients with LDK(Lumbar degenerative kyphosis). Subjects were composed of 37 old female with LDK. The subjects were tested in their spinal segment movement and spinal column curve with Spinal-$Mouse^{\leq}$ in $1^{st}$ loaded test and $2^{nd}$ loaded test and then tested lumbar extensor muscle power with $Medx^{\leq}$ lumbar extension machine. The results of this study, were as follow; There were statistically significant difference $1^{st}$ loaded test and $2^{nd}$ loaded test in upright position increase spinal column forwardly(p<0.01) and decrease lumbar lordosis angle(p<0.01), but no statistically significant difference $1^{st}$ loaded test and $2^{nd}$ loaded test thoracic and hip & sacrum curve angle. Their lumbar extensor muscle poser is very weakness, 61.4% of normal people.

The test for internal and external rotation of hip joint, was donet from September 2 to 9, 2002, with the participation of 50 male/female university students who are in a normal health condition. Results are : 1. When applying the external rotation of 45 degrees angle ; 1) In a sitting position, for male it results in an increase of 5 degrees on right and left sides each. 2) In a sitting position, for female there is no change on both right and left sides. 3) In a supine position, for both male and female it results in an increase of 5 to 10 degrees on right and left sides each. 4) In a prone position, for male it results in an increase of 5 degrees on the left side only. 5) In a prone position, for female it results in an increase of 5 to 10 degrees on right and left sides each. 2. When applying the internal rotation of 45 degrees angle ; 1) In a sitting position, for male it results in a decrease of 5 degrees on right and left sides each. 2) In a sitting position, for female there is no change on both right and left sides. 3) In a supine and prone position, there is no change for male. 4) In a supine position, for female it results in an increase of 5 to 10 degrees on right and left sides each. 5) In a prone position, for female it results in an increase of 5 degrees on right and left sides each.
