Illustration of the neurodynamic technique (NDT) and the sham intervention. The NDT (A) included positioning and range of motion known to cause significant stress across the median nerve.²⁰,²¹ Specifically, the NDT included 25° of contralateral cervical sidebending, ipsilateral shoulder depression and abduction to 90°, shoulder external rotation to 90°, 45° of elbow extension, forearm supination, and repetitive wrist and finger flexion and extension through the available range of motion. The sham technique (B) was intended to minimize stress across the median nerve and consisted of the cervical spine maintained in neutral sidebending, no ipsilateral shoulder depression and abduction to 45°, shoulder external rotation to 45°, 45° of elbow extension, and forearm pronation, and repetitive wrist and finger flexion and extension applied passively by the examiner through the available range of motion.
