Physiological mechanisms of efficacy of cervical flexor muscle retraining

Funded Activity Summary

Neck pain is a significant problem in society and its frequency is beginning to match the proportions of back pain, probably reflecting our increasingly sedentary lifestyles. Several problems have been identified in the muscle system in persons who suffer from neck pain. Therapeutic exercise has been found to have benefit in preventing and relieving pain and improving the neck function. Currently there are several, quite different methods of exercise and there is controversy regarding how therapeutic exercise works. It has been argued that parameters such as changes in muscle strength, endurance, joint position sense or muscle coordination may be responsible for the clinical efficacy. It is difficult to disentangle the effective component of exercise strategies and thus prescribe the most effective exercise strategies. This series of experiments will evaluate the physiological factors that change with a specific exercise intervention and to compare different exercise modalities in order to identify the most effective means to induce these changes. Cervical muscle training, using a proven exercise intervention strategy for chronic neck pain and headache, has been chosen as the model to investigate these questions. This exercise strategy has been chosen not only because it has been shown to be effective, but also because it does not conform to contemporary rationales for strength or endurance training. Thus while effective in relieving pain, it is unlikely to produce changes in these parameters. Thus other mechanisms are likely to be responsible for the clinical change. This research stands to make a significant contribution to exercise therapeutics by identifying the effective components of different exercise methods and investigating the pain relieving effects of the specific exercise. This knowledge will lead to the construction of a research based exercise program for neck pain patients, rather than have the current situation of often arbitrary choice of exercise.
