Objective To determine the effectiveness of dynamic muscle training and relaxation training for chronic neck pain.
Design Randomised controlled trial.
Setting Five occupational healthcare centres, Tampere, Finland.
Participants 393 female office workers (mean age 45 years) with chronic non-specific neck pain randomly assigned to 12 weeks of dynamic muscle training (n = 135) or relaxation training (n = 128), plus one week of reinforcement training six months after baseline; or ordinary activity (control group; n = 130).
Main outcome measure Change in intensity of neck pain at three, six, and 12 months.
Results No significant difference was found in neck pain between the groups at follow up. However, the range of motion for cervical rotation and lateral flexion increased more in the training groups than in the control group.
Conclusions Dynamic muscle training and relaxation training do not lead to better improvements in neck pain compared with ordinary activity.
