Abstract
|
|
|
PURPOSE : This study is research about deep trunk muscles (DTM) that is important and serve to control the movement of the trunk to provide stability during movement for human. In this study, trying to prove a change of DTM of aging in the ultrasound image.
METHODS : We measured via an ultrasound image during rest and contraction of DTM in 42 young and 48 old people, and then we measured the change of thickness and symmetry.
RESULTS : Symmetry showed a significant difference only external oblique (EO) in the young(p<.05). In the elderly, it was found that ratio of contraction was greater transverse abdominis than EO.
CONCLUSION : I considered it could lead to improvement of activity of daily life by applying intervention for recovery of motor control of TrA for the elderly in clinical practice.
