Abstract

Purpose : The purpose of this study was to find the effects of the transverse abdominis/internal abdominal oblique (TrA/IO), multifidus (MF) muscles while stabilization exercise was performed in a four-point kneeling position on the unstable surface. Methods : Twenty healthy adults volunteered to participate in this study. Each subject was instructed regarding maximum voluntary isometric contractions (MVIC) and stabilization exercise in four-point kneeling on the unstable surface. While MVIC and stabilization exercise of individual muscles were being performed, activation of the muscles was measured using surface electromyography (EMG). Activation of the muscles while performing stabilization exercise in four-point kneeling on the unstable surface was normalized to a percentages of the MVIC. Results : TrA/IO, MF muscles showed no significant differences among the surfaces. Conclusion : Activation of the trunk muscles while performing stabilization exercise in four-point kneeling does not effect on the surface.
