Biomechanical analysis of ulnar nerve gliding and elongation: implications for nonsurgical ulnar nerve release in cubital tunnel syndrome

Ulnar nerve gliding was most severe during passive wrist movement in elbow flexion and forearm supination. This result suggests that passive wrist movement from flexion to extension with the elbow flexed and forearm supinated may be the most effective nonsurgical ulnar nerve release position to treat cubital tunnel syndrome. Attention should be paid to the elbow flexion angle during nonsurgical ulnar nerve release to not exacerbate cubital tunnel symptoms. Level of evidence: III.
