  • comparison of electrical nerve stimulation electrical muscle stimulation and magnetic nerve stimulation to assess the Neuromuscular Function of the plantar flexor muscles
    European Journal of Applied Physiology, 2015
    Co-Authors: Samuel Verges, Guillaume Y. Millet, Nicola A. Maffiuletti, Daria Neyroud, John Temesi, Bengt Kayser
    Abstract:

    Introduction As it might lead to less discomfort, magnetic nerve stimulation (MNS) is increasingly used as an alternative to electrical stimulation methods. Yet, MNS and electrical nerve stimulation (ENS) and electrical muscle stimulation (EMS) have not been formally compared for the evaluation of plantar flexor Neuromuscular Function.

  • Electrical stimulation for testing Neuromuscular Function: From sport to pathology
    European Journal of Applied Physiology, 2011
    Co-Authors: Guillaume Y. Millet, Vincent Martin, Alain Martin, Samuel Verges
    Abstract:

    The use of electrical stimulation (ES) can contribute to our knowledge of how our Neuromuscular system can adapt to physical stress or unloading. Although it has been recently challenged, the standard technique used to explore central modifications is the twitch interpolated method which consists in superimposing single twitches or high-frequency doublets on a maximal voluntary contraction (MVC) and to compare the superimposed response to the potentiated response obtained from the relaxed muscle. Alternative methods consist in (1) superimposing a train of stimuli (central activation ratio), (2) comparing the MVC response to the force evoked by a high-frequency tetanus or (3) examining the change in maximal EMG response during voluntary contractions, if this variable is normalized to the maximal M wave, i.e. EMG response to a single stimulus. ES is less used to examine supraspinal factors but it is useful for investigating changes at the spinal level, either by using H reflexes, F waves or cervicomedullary motor-evoked potentials. Peripheral changes can be examined with ES, usually by stimulating the muscle in the relaxed state. Neuromuscular propagation of action potentials on the sarcolemma (M wave, high-frequency fatigue), excitation-contraction coupling (e.g. low-frequency fatigue) and intrinsic force (high-frequency stimulation at supramaximal intensity) can all be used to non-invasively explore muscular Function with ES. As for all indirect methods, there are limitations and these are discussed in this review. Finally, (1) ES as a method to measure respiratory muscle Function and (2) the comparison between electrical and magnetic stimulation will also be considered.

  • effects of a short proprioceptive Neuromuscular facilitation stretching bout on quadriceps Neuromuscular Function flexibility and vertical jump performance
    Journal of Strength and Conditioning Research, 2013
    Co-Authors: Nicolas Place, Nicola A. Maffiuletti, Yannick Blum, Stephane Armand, David G Behm
    Abstract:

    The inclusion of relatively long bouts of stretching (repeated static stretches of ~30 seconds) in the warm-up is usually associated with a drop in muscle performance. The purpose of this study was to assess the effect of a novel self-administered proprioceptive Neuromuscular facilitation (PNF) paradigm with short periods of stretching and contraction on quadriceps Neuromuscular Function, vertical jump performance, and articular range of motion (ROM). Twelve healthy men (age: 27.7 ± 7.3 years, height: 178.4 ± 10.4 cm, weight: 73.8 ± 16.9 kg) volunteered to participate in a PNF session and a control session separated by 2�7 days. The PNF stretching lasted 2 minutes and consisted of 4 sets of 5-second isometric hamstring contraction immediately followed by 5 seconds of passive static stretch of the quadriceps immediately followed by 5 seconds isometric quadriceps contraction for each leg. For the control session, the participants were asked to walk at a comfortable speed for 2 minutes. Active ROM of knee flexion, vertical jump performance, and quadriceps Neuromuscular Function were tested before, immediately after, and 15 minutes after the intervention. The PNF stretching procedure did not affect ROM, squat jump, and countermovement jump performances. Accordingly, we did not observe any change in maximal voluntary contraction force, voluntary activation level, M-wave and twitch contractile properties that could be attributed to PNF stretching. The present self-administered PNF stretching of the quadriceps with short (5-second) stretches is not recommended before sports where flexibility is mandatory for performance.
