Local and Widespread Hypoalgesic Effects of Neurodynamic Mobilization in Healthy Controls

"Subjects will be positioned in supine with the examiner supporting his/her arm and facing caudally. The arm will be taken into the ULNT2a position as described in Butler's text - so as to bias the median nerve. Once passive resistance is felt or a feeling of mild tension is reported in the median nerve field, a series of mobilizations will be performed to slide the nerve proximally and distally in an alternating manner via providing wrist extension with concurrent shoulder girdle elevation and then providing wrist flexion with concurrent shoulder girdle depression. This will be performed for 2 sets of 10 cycles at a rate of 6 seconds per cycle (3 sec in each position) - not moving further into described tension or passive resistance."

Once passive resistance is felt or a feeling of mild tension is reported in the median nerve field, a series of mobilizations will be performed to tension the nerve in an alternating on/off manner via providing wrist extension with concurrent shoulder girdle depression and then providing wrist flexion with concurrent shoulder girdle elevation. This will be performed for 2 sets of 10 cycles at a rate of 6 seconds per cycle (3 sec in each position) - not moving further into described tension or passive resistance."

Subjects will be positioned in supine with the examiner supporting his/her arm and facing cranially - in a similar position as the UNLD1 test described previously. From here, the therapist will position the patient's arm in 45 deg. of shoulder abduction without scapular depression, 45 deg. of shoulder external rotation, 45 deg. of elbow flexion, and forearm pronation. From this position, a series of sham mobilizations will be performed by passively alternating flexion and extension of the wrist for 2 sets of 10 cycles at a rate of 6 seconds per cycle (3 sec in each position).
