Medial gastrocnemius is more activated than lateral gastrocnemius in sural nerve induced reflexes during human gait.
In humans the sural nerve was stimulated at one of 16 phases of the step cycle. In MG (medial gastrocnemius) the amplitude of the P2 responses (latency 80-93 ms) was on average 1.3 times larger than the corresponding background activity while this was 0.9 for LG (lateral gastrocnemius; predominantly suppressive responses). It is speculated that such differences contribute to an exorotation mome...

متن کاملAbeta fibers mediate cutaneous reflexes during human walking.
During human gait, transmission of cutaneous reflexes from the foot is controlled specifically according to the phase of the step cycle. These reflex responses can be evoked by nonnociceptive stimuli, and therefore it is thought that the large-myelinated and low-threshold Abeta afferent fibers mediate these reflexes. At present, this hypothesis is not yet verified. To test whether Abeta fibers ...
متن کاملSural Nerve Interposition Grafting during Radical Prostatectomy.
In 1997, autologous sural nerve grafting to reconstruct bilaterally resected cavernosal nerves was successfully performed in patients undergoing radical retropubic prostatectomy. After 12 months, one third of these patients had erections sufficient for intercourse. Since that time, patients who have had neurovascular bundle resection and sural nerve grafting have continued to show promising res...
متن کاملReflexes from the superficial peroneal nerve during walking in stroke subjects.
The function of ipsilateral cutaneous reflexes was studied with short trains of stimuli presented pseudorandomly to the superficial peroneal nerve (SP; innervates the top of the foot) during treadmill walking in neurologically intact (NI) subjects and subjects who had had a stroke. Ankle and knee joint angles together with electromyograms (EMG) of tibialis anterior (TA), soleus (SOL), medial ga...
