Aim:
Neck pain is a common disorder in industrial countries. With upto 37% of individuals have developing and persistent symptoms.
In addition, neck pain imposes a considerable economic burden on the health care system. Although there are many potential
contributing factors to neck pain, Myofascial Trigger Point (MTP) is known as the chief cause of headache and neck pain. Aim of this
study was to investigate the effects of arm movement on anticipatory postural control in patients with upper trapezius MTP.
Methods:
15 women (aged 26.8±2.67 years) with one active MTP and, fifteen women (aged 27.53±3.73) with one latent MTP in the
upper trapezius and, 15 normal women (aged 27.73±3.43 years) were participated in this study. Participants were asked to flex their
arms in response to a sound stimulus preceded by a warning sound stimulus.
Results:
There were significant differences in average, peak, and area of Contingent Negative Variation (CNV), Post-imperative
Negative Variation (PINV), motor times, and for reaction time (P<0/001) between active and control group. There were not significant
differences in Electromyography (EMG) measurements between passive and control group but there were significant differences in
CNV measurements (P<0/001).
Conclusion:
CNV and EMG were changed in patients with active MTP. These patients had less compatibility with environmental
stimulus and responded to a specific stimulus. The present study shows that CNV can be a new method for evaluation of the MTP.
