Abstract
In a gait motion assisting apparatus of the present invention, a thigh phase angle calculating unit calculating a thigh phase angle divides an unnormalized hip joint angle obtained based on a angle-related signal from a thigh orientation detecting unit by a stored hip joint angle normalization coefficient to calculate a normalized hip joint angle, divides an unnormalized hip joint angular velocity obtained by differentiating the unnormalized hip joint angle by a stored hip joint angular velocity normalization coefficient to calculate a normalized hip joint angular velocity, and calculate the thigh phase angle by using the normalized hip joint angle and the normalized hip joint angular velocity.
