Abstract

|
|
Purpose: The purpose of this study was to describe the effects of neck and trunk stabilization exercise on the onset time of trunk muscle contraction in the elderly.
Methods: Elderly subjects were divided into 2 groups: a neck and trunk stabilization exercise group (NTSG) and a control group (CG). The NTSG performed both neck and trunk stabilization exercises and the CG performed gait training on a treadmill, at 30 min per session, 3 times per week, over 8 weeks. Surface electromyography was employed to measure the onset times of trunk muscle contractions in the right anterior deltoid, rectus abdominis, external oblique abdominis, internal oblique abdominis, and erector spinae muscles.
Results: The NTSG subjects showed earlier and statistically significant onset of contraction in trunk muscles as compared to the CG.
Conclusion: The combination of neck and trunk stabilization exercises may more effectively improve the onset of muscle contractions in the elderly than other types of exercise. The present study's findings may be used as basic data for the development of exercise programs suitable to the elderly, specifically for the design of home exercise programs.
