Abstract
Objective: This study aimed to investigate the relationship between cervical stabilizing exercise accompanied by abdominal stabilization and deep and superficial cervical flexor muscle atrophy, as increased activity in the former may prevent compensatory movement of the latter. Methods: We included 30 healthy adults in this study. Subjects either performed cervical stabilizing exercise as per the conventional method, with the hip and knee joints in the 90° position, or in conjunction with abdominal stabilization. We measured changes in the muscle activity of the SCM, scalene, RA, EO, and IO as well as the muscle thickness of the SCM, EO, IO, longus colli, and TrA. Results: Meanwhile, the muscle thickness of the longus colli increased to a greater extent following cervical stabilizing exercise accompanied by abdominal stabilization than after stabilization with the hip and knee joints in the 90° position or when using the conventional approach. Conclusion: Abdominal stabilization helps to improve the muscle strength of the longus colli by preventing compensation of the cervical flexor muscle through the provision of trunk stability and the avoidance of chest lift.
