head positions and spinal manipulation
Each subject will then undergo a baseline MRI in a head neutral position (0 degrees rotation). They will then be placed in head rotation (45 degrees) to the non-dominant and undergo a MRI. Maximum rotation to the side with MRI will follow. Finally, each subject will receive an upper cervical rotary manipulation to the non-dominant side with MRI immediately after. A total of 4 test conditions will be evaluated (rest, 45 degree, maximal, post-manipulation). The manipulation will be performed by an experience practitioner on a bed just outside the MRI room in supine position. A controlled impulse load will be applied and the head/neck returned to neutral position. Prior to each maneuver, the subject will be queried on their comfort, condition and willingness to continue
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Exclusion Criteria
2. Healthy asymptomatic male patients who would otherwise receive cervical manipulation on a regular basis as a part of their normal learning experience and will have had a cervical manipulation in the last 3 months.
3. Sufficient English language ability to complete study questionnaires (see appendix).
4. No history of disabling neck, arm or headache pain within the last 6 months.
5. No current or prior history of neurological symptoms including, facial or extremity weakness, abnormal sensation to the face, body or extremities, uncontrolled movements, abnormal gait, dizziness, unexplained nausea/vomiting, difficulty with speaking or swallowing.
6. Subjects will have had no prior history of head trauma or prior history of surgery to the neck region.
7. No history of claustrophobia, metallic implants or tattoos to ensure compatibility with MRI requirements.
