[Purpose] The purpose of this study was to identify the effects of visual field condition on electromyography of the lower extremities during arm reaching in healthy adults, and to compare differences in electromyography of the lower extremities between young and old adults according to visual fields condition. [Subjects and Methods] Twenty-nine young persons in their 20s and 19 elderly persons...

Reconstruction of the middle third of the leg is a challenging procedure. The tibialis anterior muscle flap can be useful in reconstruction of the middle third of the leg with exposed tibia. The aim of this work was to evaluate the efficacy of tibialis anterior pivoted muscle flap for reconstruction of the middle third of the leg with functional preservation. This study, performed in the Plasti...

OBJECTIVE To describe the characteristics of leg muscle activation patterns in hemiplegic stroke patients during the movement of rising from a chair and to determine the differences of leg muscle activation patterns between stroke fallers and nonfallers. DESIGN Subjects stood up from an armless chair at a comfortable, self-paced speed. Leg muscle activation time and patterns during the sit-to...

BACKGROUND Traumatic ruptures of the tibialis anterior tendon are rare but can cause substantial functional deficiencies. This study aimed to evaluate the feasibility of a surgery for soft tissue repair of traumatic rupture of the tibialis anterior tendon by using a plate and screw fixation repair in combination with the free anterolateral thigh flaps transplantation. METHODS Eight consecutiv...

Internal iliac artery (IIA) shows frequent variations in its branching pattern. We saw variations in the branching pattern of right IIA in a male cadaver. The IIA divided into anterior and posterior divisions. The branches of the anterior division included umbilical artery, inferior vesical artery, obturator artery. The other branches arose from posterior trunk such as iliolumbar, lateral s...

BACKGROUND The motion control shoe is a well-developed technology in running shoe design for controlling excessive rearfoot pronation and plantar force distribution. However, there is little information on the leg muscle activation with different shoe conditions. HYPOTHESIS The motion control shoe can prevent excessive shank muscle activation and delay fatigue. STUDY DESIGN Controlled labor...

[Purpose] This study aimed to examine the changes in the muscle activities of each section of the tibialis anterior and gastrocnemius muscles in the functional reach test. [Subjects and Methods] This study selected those who can walk independently, can reach out their arm up to over 25 cm, can show over 90° shoulder joint bending, have not undergone an operation in the lower limb joint, and are...

PURPOSE To compare the degree of stretching of sarcomeres--in the medial gastrocnemius versus the tibialis anterior--acutely extended by tibial lengthening. METHODS The right lower legs of 6 New Zealand White rabbits were acutely distracted by 6.3 mm using an external fixator, whereas the left lower legs served as controls. Immediately after distraction, the ankle was dorsiflexed at 50 degree...

Slope-related differences in hindlimb movements and activation of the soleus and tibialis anterior muscles were studied during treadmill locomotion in intact rats and in rats 4 and 10 weeks following transection and surgical repair of the sciatic nerve. In intact rats, the tibialis anterior and soleus muscles were activated reciprocally at all slopes, and the overall intensity of activity in ti...
