001). Changes in antero-posterior mean position of the exercised leg were also observed reflecting a mean loading in a BAY 11-7082 cost more rear fOot stance (P < 0.01). The in-shoe system parameters revealed for the exercised foot, an increase of the maximal pressure value for the heel region (P < 0.05) and a decrease for the mid-foot and forepart (P < 0.05). For the non-exercised foot, the maximal pressure decreased only
in forepart (P < 0.05).
Conclusions. – Unilateral triceps surae fatigue revealed an immediate destabilisation of undisturbed stance and the observed postural strategy appears similar to these developed by patients who presented pain pathology and/or sensory deficits in lower limb.

“Objective. – The cutaneous silent period (CSP) corresponds to the inhibition of motor neuronal activity that is induced by electrical cutaneous stimulation. This motor neuronal inhibition might be useful as a therapeutic strategy for modulating the excitability of motor neurons.
Therefore, we investigated the CSP changes that can be observed using the paired-stimulation method.
Methods. – Fifteen healthy adults were recruited. The digital cutaneous nerve of the right index finger was stimulated, and the CSP was recorded at the right thenar
muscle. During the stimulation, contraction of the opposing right thumb and third finger was maintained at 20% of maximal voluntary contraction. A single stimulation was applied at the right index finger, and the duration and latency of the CSP (CSP1) was recorded. Paired electrical stimulations were then delivered with 60-, 80-, 100-, 120-, 140-, 160-, 180-, and 200-ms interstimulus intervals (151), and the latency and duration of a second CSP (CSP2) was measured and Myosin compared with that for the single stimulation.
Results. – The CSP2 onset latencies were delayed in the 60-, 80-, and 100-ms ISI when compared to CSP1. CSP2 durations were shorter in the 60-, 80-, and 100-ms ISI. No significant differences in the latencies and durations between CSP1 and CSP2 were observed for 151 durations greater than 120 ms.
Conclusions. – We found that repetitive electrical stimulation changed the latency and duration of the CSP. These results suggest that the refractory period of the spinal inhibitory circuit in CSP is less than 100 ms. (C) 2011 Elsevier Masson SAS. All rights reserved.
