INTRODUCTION A contributing factor to the loss of muscle mass and strength during aging is the reduction in the number of functioning motor units (MU). It has been shown that lifelong physically active older rats have greater numbers of MU compared with age-matched sedentary controls, suggesting that chronic exercise may preserve MU function with advancing age. This has not previously been exam...

Background This study aimed to compare stability, functional outcome, and second-look arthroscopic findings after anterior cruciate ligament reconstruction between remnant-preserving tibialis tendon allograft and remnant-sacrificing hamstring tendon autograft. Methods We matched two groups (remnant-preserving tibialis tendon allograft group and hamstring tendon autograft group) in terms of de...

Comparisons were made of muscle spindle structure between phasic and tonic muscles stained by the gold chloride method. The most significant difference was in the ring diameter of the sensory nerve terminals wrapped around the nuclear bags. In tibialis anterior it was largest, in gastrocnemius intermediate, and in soleus smallest. This order corresponds to the contraction time, tibialis anterio...

Age-related decrements within the sensorimotor system may lead to alterations and impairments in postural control, but a link to a vestibular mechanism is unclear. The purpose of the present study was to determine whether vestibular control of standing balance is altered with adult aging. Eight old (~77 years) and eight young (~26 years) men stood without aids on a commercially available force ...

No.: +918283816579 E-Mail: [email protected] Introduction: The tibialis anterior is an important muscle because of its function and its use in tendon transfer as a treatment of recurrent congenital clubfoo...

[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...
