Muscle damage after neuromuscular electrostimulation assessed by multimodal magnetic resonance imaging
Résumé
Neuromuscular electrostimulation (NMES) is useful for improving muscle function. However, it has been reported that NMES-induced muscle damage is mainly due to the specificity of motor unit recruitment (i.e., non-selective, spatially fixed, synchronous and mainly superficial). Moreover, it is documented that NMES results in a preferential activation of muscle fibers beneath and close to the stimulating electrodes (1), so that one could expect heterogeneous damage between directly and indirectly stimulated muscles. The present study aimed to test the hypothesis that NMES-induced muscle damage would be different between directly and indirectly stimulated muscles of the knee extensors using multimodal magnetic resonance imaging (MRI) including T2 mapping and diffusion tensor imaging (DTI).
