Neck Pain
Conditions
Brief summary
Determine effects of perceptions and expectations on experience of cervical spine manipulation
Detailed description
The purpose of this study is to better understand how therapists may affect a patient's thoughts/ beliefs/ opinions on cervical spine (neck) manipulation. Current evidence suggests that patients who have a positive expectation about neck manipulation are more likely to report benefit from it, and we wish to determine if the perceived experience level of the therapist and the words they use to describe neck manipulation will affect the patient's perception.
