“…1,3 Recent studies investigating the benefits of stretching and manual therapy reported decreased muscle stiffness with downregulation of muscle spindles. 1,3,16 These results correlate with clinical research demonstrating the effectiveness of manual neuromuscular facilitation (muscle energy) techniques in overhead athletes to decrease horizontal adduction deficits. 26 In light of this unexplained variability, neuromodulation of resting muscle tension may account for a portion of the unexplained variability observed within our sample.…”
