摘要:
A cervical traction device has and occipital tractioning member and a handle. The device is positioned between the occiput of a person and the floor or other surface. Rotation of the handle away from the person's torso exerts opposite forces against the occiput and the surface, which exerts a tractioning (extension) force upon the cervical spine. The occipital tractioning member can advantageously comprise first and second spaced apart plastic spheres.
