Abstract
|
|
|
Purpose: This study investigated the effects of trunk muscle activity with power grasping during one leg stance.
Methods: Twenty-eight subjects participated in this study. Subjects were divided into two groups, one that performed power grasping, and another that did not. An investigator measured the activities of a subject’s trunk muscle such as internal oblique (IO), external oblique (EO), erector spinae (ES), and gluteus medius (GM) while a subject was doing one leg stance.
Results: An independent t-test was used to analyze trunk muscle activities with power grasping during one leg stance between the experimental group and the control group. Only the EO activity differed significantly between groups (p<0.05).
Conclusion: The results indicate that one leg stance with power grasping affected trunk muscle activity. Therefore, this is a useful method for providing lumbar spine stability.
