Effect of blood flow restriction training with core stabilization exercise on muscle activity and muscle thickness in subjects with nonspecific chronic low back pain.

研究概要

Thirty-eight patients with nonspecific chronic low back pain were randomized to receive blood flow restriction (BFR) combined with core stabilization exercise (CSE) or CSE alone. The primary outcomes of interest were muscle activity (EMG) of the transversus abdominis, multifidus, and gluteus maximus. Secondary outcomes included muscle thickness (at rest and during contraction) and disability measured by the Modified Oswestry Disability Questionnaire (MODQ). Outcomes were assessed before and after a 4-week intervention period. Overall, the results of the study revealed that the BFR+CSE group demonstrated significantly greater improvements in muscle activity, muscle thickness, and disability compared with the CSE group. These findings suggest that adding BFR to CSE enhances neuromuscular adaptations and functional outcomes in individuals with chronic low back pain.
