Increases in corticospinal responsiveness during a sustained submaximal plantar flexion.
Studying the responsiveness of specific central nervous system pathways to electrical or magnetic stimulation can provide important information regarding fatigue processes in the central nervous system. We investigated the changes in corticospinal responsiveness during a sustained submaximal contraction of the triceps surae. Comparisons were made between the size of motor-evoked potentials (MEP...
متن کاملWeakness in end-range plantar flexion after Achilles tendon repair.
BACKGROUND Separation of tendon ends after Achilles tendon repair may affect the tendon repair process and lead to postoperative end-range plantarflexion weakness. HYPOTHESIS Patients will have disproportionate end-range plantarflexion weakness after Achilles tendon repair. STUDY DESIGN Descriptive laboratory study. METHODS Four-strand core suture repairs of Achilles tendon were performed...
متن کاملIs Passive Plantar Flexion Torque Determinant of Lower Limb
INTRODUCTION: It has been supposed that leg stiffness affect repeated jump performance, such as hopping. Previous study indicated that ankle joint stiffness is important in leg stiffness (Arampatzis et al. 2001). Furthermore, it was demonstrated that Achilles tendon properties could contribute to the total mechanical work during hopping (Lichtwark and Wilson 2005). On the other hand, it is know...
متن کاملExtensor plantar response elicited by passive head flexion.
Various methods of eliciting the extensor plantar response (upgoing toe through action of the extensor hallucis longus muscle in concert with one or more other flexor muscles of the leg) have been report ed (3). Among these the most well known is the method described by Babinski (Babinski sign) (3). Eliciting an extensor plantar response by head anteflexion has not been reported. In a 75-yo wom...
متن کاملIsokinetic Plantar Flexion Torque Increases after Open Gastrocnemius Recession
The amount of force developed by a muscle is related to many factors including where the muscle operates on its length-tension curve. It is well documented that placing the triceps surae muscle group in a lengthened state (i.e.: near maximal dorsiflexion) elicits maximum plantar flexion torque [1, 2]. Isolated gastrocnemius contracture (IGC) is characterized by limited dorsiflexion with the kne...
