This study aimed to determine the usefulness of classifying patients with neck pain on the basis of the results of passive scapular elevation test. We classified 21 patients with neck pain into positive (n=12) and negative (n=9) groups on the basis of passive scapular elevation test; the 2 groups then equally performed scapular stabilization exercise program for 30 min, 3 times a week, for 4 weeks. Visual analogue scale (VAS), neck disability index (NDI), and range of motion (ROM) were recorded both before and after the intervention for both groups. Paired t-test was used to determine that there were significant changes between before and after the intervention, and independent t-test was used for analyzing changes between two groups of dependent variables. After 4 weeks of training, we observed significant decrease in pain and disability (p<.05) and a significant increase in rotation, flexion, extension, and side-bending ROM (p<.05) in both groups. Further, between pre- and post-intervention evaluations, we observed a significant decrease in pain and disability and a significant increase in rotation and flexion ROM in the positive group than in the negative group (p<.05). These results indicate that passive scapular elevation test may be used to identify mechanical disorders of the cervicoscapular muscle in patients with neck pain. Therefore, we recommend the use of passive scapular elevation test to determine appropriate treatment intervention when treating patients with neck pain.

Purpose: The purpose of this study was to compare the intramuscular activation of the scapular stabilizing muscles and the upper trapezius/middle serratus anterior (UT/MSA) ratios during shrug exercise and proprioceptive neuromuscular facilitation (PNF) scapular pattern exercise. Methods: The participants of this study were 13 young adult men who voluntarily consented to participate in this experiment after listening to its purpose and methods. All participants were instructed on maximal voluntary isometric contraction and scapular exercises. The intramuscular activation of the upper trapezius (UT), lower trapezius (LT), middle serratus anterior (MSA), and lower serratus anterior (LSA) muscles while performing scapular exercises in a side-lying position were measured using surface electromyography. To analyze the muscle activation and UT/MSA ratio between the two exercises, a one-way repeated ANOVA was performed. Post-hoc analyses were conducted using Tukey's multiple comparison and analysis. Hamstring flexibility for each group was measured by a passive straight leg raising test. Results: The shrug exercise showed significantly higher UT activation compared to PNF anterior elevation and posterior elevation scapular patterns. The PNF scapular anterior elevation pattern showed significantly higher serratus anterior activation than the shrug exercise. Additionally, the UT/MSA ratios were significantly lower in the PNF scapular anterior elevation pattern than in the two exercises. Conclusion: Although shrug exercise was effective for strengthening UT, the PNF scapular anterior elevation pattern may be effective for strengthening MSA and improving the UT/MSA ratio.
