Effect of Neck Movements on Median Nerve Longitudinal Excursion During Neurodynamic Mobilization in Patients With Carpal Tunnel Syndrome

Participants will in supine. Arm will be position in standard MNT1. Shoulder, elbow, wrist and fingers will be maintained in the required position using a costumed splint throughout all testing. All movements will be limited to the range where pain or other symptoms are not provoked. Passive neck flexion and rotation will be added to MNT1 and will be applied as tensioning movements at level 3. All movements will be repeated three times and an average will be calculated. Myrin goniometer will be used to assess neck flexion and rotation. The movements order will be randomized using excel random generation function. Movements will be done by a single trained therapist. The end position will be held up to 10 seconds until median nerve excursion is recorded by US. For US capturing, the transducer will be positioned perpendicularly and aligned longitudinally with the median nerve at the wrist. Assessor will be blinded to participants grouping.
