Objective:Coupling of joint motions is crucial in ambulation and the understanding of joint coordination is important in designing integrated prosthesis that can synchronize joint motions across different joints.Therefore,the influence and adaptation of limb salvage on joint coordination should be investigated.In this study,phase portrait and continuous relative phase (CRP) methods were applied to study the difference of joint coordination between able-bodied person and transtibial amputee.These techniques were readily used to investigate the sta bility of the elderly.Methods:This pilot study conducted gait analysis on able-bodied person and transtibial am putee.Motion capture system (Vicon and AMTI Force Platform) was used to collect the joint kinematics data.
