Introduction- Walking aids are commonly prescribed for problems of pain, fatigue, equilibrium, joint instability, muscular weakness, excessive skeletal loading and aesthetics. The function of walking aid for stability, support and restraint/propulsion will directly reduce the loading on upper limb joints. The different aided gaits will produce different effects and must be optimized during the usage. The purpose of this study was to identify the loading characteristics of two patterns of aided gait (A= four point alternating gait and B= four point partial load gait) in normal subjects and rheumatoid arthritic patients.
