Reduced biceps femoris myoelectrical activity influences eccentric knee flexor weakness after repeat sprint running

, 2014
The aim of this study was to determine whether declines in knee flexor strength following overground repeat sprints were related to changes in hamstrings myoelectrical activity.

Reinnervation of Muscle Targets Enhances the Separability of Motor Unit Signals Following Peripheral Nerve Transfers

Advanced Science, EarlyView.
Injured or cut peripheral nerves can be surgically rerouted to reinnervate new muscle targets. This study demonstrates reinnervated muscles exhibit enhanced separability between individual motor unit signals, which can simplify signal recording and decomposition. These findings highlight the potential of reinnervated muscle to serve as a key biological

Longitudinal Single‐Axon‐Resolution Imaging of Peripheral Nerve Injury Response in Mice Using an Optical Window Implant

Advanced Science, EarlyView.
A minimally invasive optical window enables stable, long‐term imaging of peripheral nerves in vivo at single‐axon resolution. Dynamic processes of degeneration, regeneration, and cellular remodeling are visualized across multiple time scales within the same nerve region, providing a unique platform to study a variety of anatomical and molecular events ...

Novel Operation of Snapping Biceps Femoris Tendon

, 2016
Snapping biceps femoris tendon (BFT) over the fibular head is an uncommon cause of lateral knee pain. This study reports a case of nontraumatic painful snapping of the BFT due to a prominent fibular head that was persistent intraoperatively after fibular

Magnetic Resonance Imaging Modified Dixon Fat Quantification Analysis Is a Quantitative and Reliable Method for Evaluating Fatty Atrophy of the Hamstring Muscle Complex After Proximal Avulsion Injury

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate the reliability and validity of objective fat quantification using the modified Dixon magnetic resonance imaging sequence for assessing fatty degeneration in conservatively treated patients with proximal hamstring avulsion injuries. Methods Magnetic resonance imaging with modified Dixon sequence was used.
