Comparative StudyThe effect of load on the coordination of the trunk for subjects with and without chronic low back pain during flexion-extension and lateral bending tasks.
To evaluate if patients move their trunk sections differently than normal subjects and to determine if these differences increase when lifting a load. ⋯ The lumbar-pelvic rhythm is routinely used to evaluate low back impairments. The use of kinematic measures enhance the objectivity of the examination but the large variability of the results impair the discrimination power. Lifting a load during such an evaluation might magnify the low back impairments and increase the discrimination power of this measure.

The effects of the lower extremity joint motions on the total body motion in sit-to-stand movement.
The purpose of this study is to investigate the effects of lower extremity joint angular motions on the whole body linear motions in a sit-to-stand movement using a biomechanical model that describes the whole body linear velocity vector as functions of lower extremity joint angular velocities. ⋯ The model and the results of this study can be applied to study the control strategies, falls, and assessments of functional impairments in the sit-to-stand movement.

Kinematic and kinetic analysis of the walking pattern in hemiplegic patients with foot-drop using a peroneal nerve stimulator.
To analyze the walking pattern in hemiplegic patients using a peroneal nerve stimulator to locate possible harmful mechanical effects on the musculo-skeletal system. ⋯ Applied correctly, the peroneal nerve stimulator can be used as an aid for foot-drop correction in hemiplegic patients without causing excessive wear on the joints in the lower extremity.

Contribution of the extrinsic and intrinsic hand muscles to the moments in finger joints.
The purpose of this current work is to develop a method of estimating force produced by the extrinsic and intrinsic hand muscles, and to estimate the contribution of these muscles to the finger joint moments. ⋯ This study suggests ways of identifying the source of functional deficiency in the hand.

Comparative StudyInterference screw fixation of doubled flexor tendon graft in anterior cruciate ligament reconstruction - biomechanical evaluation with cyclic elongation.
To biomechanically evaluate interference screw fixation of the doubled flexor tendon graft in anterior cruciate ligament reconstruction using cyclic elongation. ⋯ The present study has suggested that vigorous activities should not be permitted for the patients in the early period after anterior cruciate ligament reconstruction using this fixation technique, because of its low ultimate failure load.
