KINETIC ANALYSIS OF LATERAL-WEDGE INSOLE ON SYMMETRY OF STANCE AND AMBULATION IN STROKE INDIVIDUALS Chien-Hsun Chen, Kwan-Hwa Lin, Tung-Wu Lu, Huei-Ming Chai, Pei-Fang Tang, Ming-Hsia Hu School and Graduate Institute of Physical Therapy, National Taiwan University Institute of Biomedical Engineering, National Taiwan University Introduction The stroke patients often have problems with asymmetry of stance and ambulation. This study was to assess the symmetry of weight bearing in stroke patients during stance and ambulation with and without wearing a lateral-wedge insole on the non-paretic side. Methods There were sixteen hemiplegic patients (mean age: 54.12±2.85 year old) with mean duration of illness 90.69 ± 21.77 days. The subject with and without 5∘lateral-wedge insole performed quiet standing on platforms (AMTI, USA) for 10 seconds, then walked with comfortable speed along a 6-m woody walkway. Symmetry index (SI) indicated the difference between the paretic and non-paretic limbs with zero being symmetric. Results The SI of vertical ground reaction force (GRF) during static standing was significantly improved (from 60.82% to 48.02%, p
