Abstract

|
Objective: The purpose of this study was to investigate the effect of a lower trapezius strengthening exercise program on an unstable support surface on pain, neck dysfunction, psychosocial factors, and postural alignment in neck pain patients with forward head posture.
Design: A randomized controlled trial
Methods: A total of 36 neck pain patients participated in this study. Screening tests were performed and assigned to experimental group (n＝18) and control group (n＝18) using randomization program. Both groups performed the lower trapezius strengthening exercise program. In addition, in the experimental group, an exercise program for lower trapezius muscle strengthening was performed on an unstable support surface. All interventions were performed 3 times a week, for a total of 5 weeks. quadruple visual analogue scale (QVAS), neck disability index (NDI), short form (SF)-12, and postural alignment were measured before and after the intervention to compare their effectiveness.
Results: Both groups showed significant differences in QVAS, NDI, SF-12, and postural alignment before and after intervention (p<0.05). In addition, the experimental group showed significant differences in NDI and postural alignment compared to the control group (p<0.05).
Conclusions: The lower trapezius strengthening exercise program on unstable support surfaces is an effective intervention method with clinical significance in improving neck disability and postural alignment in patients with neck pain with forward head posture.
