Study Overview
Brief Summary
Passive accessory cervical mobilization is widely used as a clinical approach to the management of musculoskeletal pain of spinal origin. The purpose of the study is to determine if passive cervical mobilization can improve motor function in situations where motor performance is not impaired by the presence of pain.
Detailed Description
Cervical mobilization has been shown to elicit effects on pain perception, autonomic function and motor function in subjects who experience musculoskeletal pain. The improvement in motor function may be a direct effect of the treatment or secondary to a hypoalgesic effect. This study aims to demonstrate whether it is possible to alter motor function following joint mobilization, in situations where motor performance is not impaired by pain.

Arms & Interventions
Passive cervical mobilisation
Grade III cervical mobilization technique as described by Maitland. Applied to left C5/6 Segment.
Intervention: Passive cervical mobilisation (Other)
Manual contact
Manual contact control, which involved light manual contact on the left C5/C6 segment as if to perform the treatment technique.
Intervention: Manual contact (Other)
Non-contact control
Non-contact control, which involved the subject resting in the treatment position without any physical contact between the researcher and the subject.
Outcomes
Primary Outcomes
Electromyography of sternocleidomastoid muscle.
Time Frame: Pre intervention (baseline) and 1 minute post intervention
Measurement of sternocleidomastoid muscle activation during deep neck flexion. The degree of neck flexion is determined by a pressure biofeedback unit place underneath the neck. EMG of the left and right sternocleidomastoids are recorded for 5seconds at each level of neck flexion
Secondary Outcomes
- Pressure pain threshold(Pre intervention (baseline) and 1 minute post intervention)
