Effectiveness of Transcutaneous Neuromodulation on Abductor Muscles Electrical Activity in Subjects with Chronic Low Back Pain: A Randomized, Controlled, Crossover Clinical Trial.

研究概要

Forty-one patients with non-specific chronic low back pain were randomized to receive either a magnetic particle tape (MPT; n=21) or a sham magnetic particle tape (SMPT; n=21). The primary outcome of interest was the improvement in muscle strength of the Gluteus Medius and Tensor Fascia Lata measured via the Hip Stability Isometric Test (HipSIT) with a hand-held dynamometer and surface electromyography (sEMG). Secondary outcomes of interest included muscle recruitment and maximum voluntary contraction. Outcomes were assessed immediately post-intervention. Overall, the results of the study revealed that the application of MPT significantly increased muscle strength and sEMG activity in both muscles compared to the SMPT. The study suggests that lumbar metameric neuromodulation with MPT improves muscle activation of the hip musculature in patients with NSCLBP.
