Abstract: A wearable physical rehabilitation device configured to separate the thighs of a subject to promote proper posture of the pelvis while walking is provided. The device comprises a supporting belt fitted around the subject's waist, a 3D wedge-like PU-foam structure arranged between the subject's thighs, a saddle-shaped structure for receiving the subject's buttocks, and a hollow control handle arranged anteriorly relative to the subject's body. The 3D wedge-like structure has a hole and is attached to the belt by a pair of ascending straps each passing through the hole. Each of a pair of lateral straps passes through the hole and attaches the 3D wedge-like structure to and around one of the thighs. The handle has one pair of descending straps extending therefrom and attaching to the saddle-shaped structure and another pair of ascending straps extending therefrom and attached to each other behind the subject's neck.
