Chiropractic care will include manual spinal manipulation, with light soft tissue massage as indicated to facilitate the spinal manipulative therapy. The spinal levels treated will be determined by the individual chiropractors by static and/or motion palpation. Patients will attend 20, 1 hour sessions of rehabilitative exercises for the neck and upper body. Each session will begin with a 10-minute aerobic warm-up of the upper body and five minutes of light stretching to prepare for the strengthening exercises.
