Abstract
Neck pain is a major problem in modern society. Sedentary office workers face a particularly high-risk of developing neck pain because their neck and shoulders are generally static when they work. To prevent further progress, it is crucial to detect early signs of subclinical neck pain in order to allow prompt intervention. Since previous studies showed that proprioception is critical to the maintenance of joint stability under dynamic conditions, impairment of proprioception might be a predisposing factor in the development of clinical pain. Although impaired neck proprioception has been demonstrated in patients with chronic neck pain, previous studies have not consistently shown any association between pain intensity and proprioceptive performance. We therefore investigated whether temporal aspects of pain are associated with cervicocephalic kinesthetic sensibility. One hundred and twenty-seven adults with or without subclinical neck pain undertook two tasks, repositioning their heads to the neutral head position (Head-to-NHP) and target position (Head-to-Target) in sagittal and transverse plane. Absolute error was calculated from position data recorded by an ultrasound-based motion analysis system. Pain frequency, duration, and intensity were evaluated using a questionnaire. A mixed effects model was constructed to test the effect on reposition error by different pain factors, with age, gender and maximal cervical range of motion as covariates. A higher pain frequency was associated with greater reposition errors for all movement directions in the Head-to-NHP task. No consistent effect was observed for pain intensity or duration.
We also recruited 72 subjects (39 in the exercise group, 33 in the control group) from the above population to investigate the effectiveness of an exercise program involving proprioceptive training and deep muscle training. After 6-week intervention, the exercise group showed a decrease of head repositioning errors in Head-to-NHP task and pain frequency. No significant change was found in pain intensity and neck disability index. These results indicated that a weekly proprioceptive training has a positive effect on head repositioning ability and pain frequency, but not necessarily effective on the pain intensity and disability level.
