Against　the　backdrop　of　accelerated　ageing　around　the　globe,　an　increasing　number　of　individuals　suffer　from　hip　motion　disability　and　gait　disorders.　In　this　paper,　the　performance　analysis　of　a　novel　parallel　assistive　mechanism　with　2　DOF　for　hip　adduction/abduction　(AB/AD)　and　flexion/extension　(FL/EX)　assistance　is　completed　and　evaluated,　particularly　the　velocity　and　force　transfer　features.　The　analysis　shows　that　the　assistive　mechanism　has　advantages　of　fine　motion　assistive　isotropy,　high　force　transfer　ratio　and　large　force　isotropic　radius,　which　indicates　that　the　parallel　assistive　mechanism　is　suitable　for　hip　AB/AD　and　FL/EX　assistance.
