Cervical Spine Manipulation Affects on Balance and Proprioception

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01745705

Brief Summary:
Cervical spine manipulation (CSM) is utilized by many health care practitioners in the management of patients with neck pain and headache. How CSM works is not understood however, most researchers agree that there is likely a combination of mechanical, neurophysiological and placebo effects. This study will test for possible neurophysiological effects by examining for changes in a person's ability to reposition their head and neck in space, and maintain their balance following CSM.

Condition or disease Intervention/treatment Phase
Neck Pain Headache Other: Cervical Spine Manipulation Other: Manual Contact Not Applicable

Detailed Description:
Consenting participants will have their proprioception tested through a joint repositioning error test for their cervical spine, and also have their balance tested through a Neurocom Balancemaster. Following these pre-intervention measures, they will receive in a random order, either a cervical spine manipulation (CSM) or a sham manipulation, and then have tests repeated to analyze for changes and differences between interventions.

Arm Intervention/treatment
Experimental: Cervical Spine Manipulation
Subjects will lie supine on a treatment table and receive a high velocity low amplitude thrust joint manipulation to their cervical spine in rotation to each side of the neck.
Other: Cervical Spine Manipulation
Sham Comparator: Manual Contact
Subjects will lie supine on a treatment table and have their suboccipital region gently cupped by the therapist for 30 seconds. No movement or force will be applied, just simple manual contact.
Other: Manual Contact

Primary Outcome Measures :
  1. Cervical joint proprioception [ Time Frame: 1 day (Immediately after the intervention) ]
    Subjects wear a headband with a mounted laser pointer and sit 1 meter away from a wall. They assume their comfortable neutral cervical posture and then close their eyes and extend their cervical spine and return to their neutral posture with eyes closed. The laser pointer marks the point of return and we measure the difference between start and end points for error.

Other Outcome Measures:
  1. SMART Neurocom Balance Master [ Time Frame: 1 day (Immediately after the intervention) ]
    Subjects stand on a force plate on a SMART Neurocom Balance Master and complete a Sensory Organization Test (SOT) program which assesses somatosensory, visual and vestobular systems used in maintaining balance.
