简要总结
The purpose of this study is to determinate whether the application of electric currents produce changes in the excitability of alpha moto neurone. Moreover evidence whether the effect of the electric currents can change the tone of the muscle under stimulation in healthy volunteers
详细描述
In the last years several experimental studies have evidenced that the transcutaneous electric nerve stimulation (TENS) in peripheric application can cause a decrease of spasticity and modulation of H-reflexes.
But if the application is in the central nervous system the results are different. So the purpose of this study is quantify the modulation of the excitability of alpha moto neurone when the application of the current is in the central nervous system compared with a sham group.

结局指标
主要结局
Post treatment H reflex
时间窗: Immediately after treatment at 40 min.
H-reflex data are obtained by EMG signal. The EMG electrode (SignalConditioningElectrodes v2.3, Delsys Inc., USA) is fixed on triceps surae by the SENIAM protocol (www.seniam.org). The stimulator electrode is fixed on the peroneus nerve, in the popliteal fossa.
Baseline H reflex
时间窗: baseline at 0 min.

During treatment H reflex
时间窗: During treatment at 33min.

次要结局
- Muscle tone during treatment(During treatment at 35 min.)
