The Effect on the Asymmetric load of Bag Weights for Dynamic Postural Stability Index & Center of Pressure Variables during Level Walking
[Thesis] Asymmetric Bag Weight & Posture (Center of Pressure)
This purpose of this study was to analyze the effect on the asymmetric load of bag weights for dynamic postural stability index & Center of Pressure variables during level walking. Participants selected as subject were consisted of young women(n=10), divided into the kinds of 3 bag weights(0kg, 3kg, 5kg).. Analyzed GRF variables during gait were medial-lateral (ML), anterior-posterior(AP), vertical(V), dynamics postural stability index(DPSI), ΔCOPx, ΔCOPy, COP area, medial-lateral(M-L), anterior-posterior(A-P) deviation of venter of pressure. The results analyzed from the above were as follows; 1. MLSI, APSI, VSI and DPSI didn`t show significant different statistically according to increase of bag weights, But, 5kg bag weight showed more decrease in dynamics postural stability index than that 0kg, 3kg bag weights during level walking. 2. Among variables of center of pressure, 5kg bag weight showed more linear relationship in pathway than that of 0kg, 3kg bag weights in ΔCOPx. Also, COP area showed increasing tendency according to decrease of bag weights. 3. M-L COPD didn`t show significant different statistically according to increase of bag weights, finally A-P COPD showed significant difference statistically in dynamic postural according to increase of bag weights.
