Aim:
Myofascial pain syndrome is a significant source of mechanical pain. The aim of this study is to investigate the effects of Active
Myofascial Trigger Points (AMTrPs) on muscle pattern in females with upper trapezius AMTrPs.
Methodology:
15 women (aged 26.8±5.9 years) with one AMTrPs in the upper trapezius, and 15 healthy women (aged 27.7± 3.4
years) participate in this study. We ask participants to stand for 10 seconds in an erect comfortable standing position to investigate
the onset of muscle activation and muscle pattern. We consider the onset of Anterior Deltoid (AD) as the starting point in marking
the onset of Cervical Paraspinal (CP), Lumbar Paraspinal (LP), left and right Upper Trapezius (UT), Sternocleidomastoid (SCM), and
medial head of gastrocnemius. We ask participants to flex their arms in response to a sound stimulus preceded by a warning sound
stimulus.
Results:
In the AMTrPs group, the onset of all of muscles activity except SCM is significant later than the control group (p<0.001).
Also, the results of experiments on the AMTrPs group show a different recruitment pattern compared with that on control group.
Conclusions:
According to the results, muscles experience delay in muscle activation and alterations in their recruitment pattern
during rapid arm flexion. These changes may serve as the adaptive motor control strategies due to the presence of AMTrPs in UT
muscle. It can be concluded that the application of motor control techniques might be useful in treatment of patients with AMTrPs.
