Our interest in tendon transplantation in leprosy was first aroused by the report of Brand (1952), and the possibility of using tibialis posterior as a dorsifiexor was further stimulated by the report ofWatkins, Jones, Ryder and Brown (1954), who had used this muscle in poliomyelitis by bringing it through the interosseous membrane. Since we began this series Brand (1956) has stated that he has...

Tibialis posterior tendon ruptures associated with closed medial malleolar fractures are rare. This article describes the association of tibialis posterior tendon ruptures with closed, high-energy, distal tibia fractures. Tendon ruptures are likely to be identified intraoperatively or missed if clinical evaluation at acute injury is limited. A high index of suspicion is required to diagnose thi...

The compound electromyographic response to a single nerve stimulus was examined in the cat tibialis anterior muscle preparation, to determine the cause of and to find a method of preventing multipeaking of the waveform. Bundles of the sciatic nerve were separated and stimulated while the response was detected by unipolar electrodes and analysed with an instrument specifically designed for this ...

INTRODUCTION In this study we tested the hypothesis that tirasemtiv, a selective fast skeletal muscle troponin activator that sensitizes the sarcomere to calcium, could amplify the response of muscle to neuromuscular input in humans. METHODS Healthy men received tirasemtiv and placebo in a randomized, double-blind, 4-period, crossover design. The deep fibular nerve was stimulated transcutaneo...

Traumatic laceration of the tibialis anterior tendon complicating a closed tibial shaft fracture is a rare injury pattern. Only 3 such cases have been reported to date in the English literature and all were missed on initial examination. A case of a 17-year-old motorcyclist with an acute laceration of the tibialis anterior tendon resulting from a closed oblique tibial shaft fracture is presente...

Tibialis posterior tendon rupture in the setting of pronation-type ankle fractures can lead to long-term debility as a result of chronic tendon dysfunction. This rare injury pattern presents a diagnostic challenge because thorough preoperative examination of the function of the tendon is limited by pain, swelling, and inherent instability of the fracture. As such, a high index of suspicion is n...

Skeletal muscle dysfunction is a well-recognised hallmark of chronic obstructive pulmonary disease (COPD) leading to exercise intolerance. The vastus lateralis of COPD patients is characterised by reduced mitochondrial enzyme activity; however, this is not the case in the tibialis anterior. It is, however, unclear whether the compromised oxidative capacity in the vastus is due to reduced mitoch...

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...
