Background and objectives: Chronic neck pain affects the musculoskeletal system in the neck, and fatigue of the muscles around the shoulder and thoracic wall. This study aimed to compare respiratory muscle strength, and anterior scalene (AS) muscle activity in participants with chronic neck pain and participants without neck pain.
Method: Ten participants with chronic neck pain over six months and ten participants without neck pain performed respiratory muscle strength tests and measured AS muscle activity while performing the respiratory muscle strength test.
Results: Participants with neck pain found that respiratory muscles strength inhalation and exhalation were lower than participants without neck pain (51.1 ± 5.5 and 72.5 ± 4.9 cmH2O, p <0.001) and (59.1 ± 3.3 and 80.0 ± 3.4 cmH2O, p <. 0.001). During the inhalation muscle strength test, AS muscle activity of right and left site in participants with neck pain were higher than subjects without neck pain (58.7 ± 11.8 and 46.1 ± 6.7, p <0.05) and (62.9 ± 14.2 and 47.6 ± 3.8, p <0.05) respectively.
Conclusion: Participants with chronic neck pain for more than 6 months had lower respiratory muscle strength than participants without neck pain and increases AS muscle activity while performing the inhaled muscle strength test compare with participants without neck pain.
