Objective: To investigate the effects of therapeutic exercises and sleeping neck support contoured pillows on patients with chronic neck pain.
Methods: Using a factorial design in a prospective clinical trial, participants were equally allocated at random to 4 treatment groups in the study: (1) placebo control, of hot or cold packs and massage; (2) sleeping neck support pillow and placebo; (3) active neck exercises and placebo; and (4) combined exercise and sleeping neck support pillow and placebo. Participants were treated by physical therapists over a 6 week period and assessed by masked independent assessors at 0, 3, 6, 12, 24 weeks, and 12 months, with the 12 week assessment being the primary decision time.
Objective: To examine various factors associated with low back pain (LBP) in an industrial setting.
