Summary

Background \& Significance Pain is the primary reason many patients seek care from healthcare professionals who utilize various manual therapy techniques. Gaining further understanding of the hypoalgesic properties of such techniques can enable practitioners to more skillfully integrate them in managing patients presenting with pain. Previous research has revealed that various manual techniques result in both local and widespread hypoalgesic changes in asymptomatic controls and patients in pain. Much of this previous research has investigated thrust manipulation; however, there is a paucity of similar research investigating these effects in neurodynamic mobilization. Specific Aims Aim: To assess for immediate local and widespread hypoalgesic effects of neurodynamic mobilization applied to the upper extremity. Hypotheses: * Subjects who receive neurodynamic mobilizations will exhibit greater positive changes in local and widespread Qualitative Sensory Testing (QST) measures compared to those who receive a sham mobilization. * Subjects who receive neurodynamic mobilizations will exhibit greater positive changes in elbow ROM and reported sensation intensity with upper limb neurodyndamic testing as compared to those who receive a sham mobilization. Aim: To assess for differences in immediate local and widespread hypoalgesic effects of sliding vs tensioning neurodynamic mobilization techniques applied to the upper extremity Hypotheses: * Subjects who receive sliding neurodynamic mobilizations will exhibit greater positive changes in local and widespread QST measures compared to those who receive tensioning neurodynamic mobilization * Subjects who receive sliding neurodynamic mobilizations will exhibit greater positive changes in elbow range of motion (ROM) and reported sensation intensity with upper limb neurodynamic testing testing compared to those who receive a tensioning neurodynamic mobilization

Interventions

Type	Name	Description
OTHER	Neurodynamic Slider Mobilization	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.
OTHER	Neurodynamic Tensioner Mobilization	Subjects will be positioned in supine with the examiner supporting his/her arm and facing caudally. The arm will be taken into the ULND2a 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 "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.
OTHER	Sham Neurodynamic Mobilization	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).
