Research on the Characteristics of Self-control Balance Behavior during the Process of Gait Instability
Abstract
In this paper, the process that people return to balance by self-adjusting when they accidently slip was studied, and we designed walking tests under different road conditions in both dry and oily levels. Three different results about healthy subjects on different road walking streets are obtained, namely, “non-slipâ€, “slip with recovery†and “slip and fallâ€. From the experiment, we received the data of joint torque and angle of lower limbs and electromyographic (EMG) signals for “non-slip†on dry ground, “slip with recovery†on oily ground and “slip and fall†on oily ground. Through comparing and analyzing the data we have received, we find that the human body’s each joint of lower limbs all play important roles on the body balance recovery at different times. And the human body optimizes the reaction order of muscles by improving muscle contraction force and speed, which makes the body’s center of mass be controlled within the scope of the balance and avoids the slip of the body.
