Correlation of force sense error test measured by a pressure biofeedback unit and EMG activity of quadriceps femoris in healthy individuals.

摘要: Abstract Background Our study developed a force sense error test (FSET) method for use on the quadriceps muscle, which could be employed in clinical practice to correlate results of muscle activity levels determined by surface electromyography (sEMG). Methods Twenty-four healthy individuals were included study. A pressure biofeedback unit (PBU) placed under knee joint, was used evaluation. First, maximum contraction value with PBU. Next, 50% and 65% analysis. Concurrently, norm values sEMG. Simultaneously, recorded while testing FSET using Each measurement repeated triplicate, average constant errors observed PBU mmHg. Results The both normal mmHg positively correlated change sEMG (p  Conclusions relationship between measured changes level showed that can proprioceptive evaluation region.
