Gait Variability Detects Women in Early Postmenopause With Low Bone Mineral Density

(A) GaitMAT II System. (B) Step length, defined as the distance between contacts of the contralateral extremities. Step length is defined with respect to the advancing limb.⁷⁷ (C) Step width, defined as the lateral distance between contralateral footfalls. Thus, right step width is defined with respect to the left trailing limb and left step width is defined with respect to the right trailing limb.⁷⁷ (D) Stride length, defined as the distance from the contact of one foot to the subsequent contact of the same foot. Initial contact typically is used as the measurement reference. One stride represents the completion of one cycle of gait.⁷⁷ (E) Step time, defined as the time necessary to complete a right or left step length.⁷⁷ (F) Stance time, defined as the time a limb is in contact with the ground.⁷⁷ Photographs used with permission of E.Q.
