Extending the Law of Intersegmental Coordination: Implications for Powered Prosthetic Controls
The study analyzed intersegmental coordination in lower-limb 3D data by extending the Law of Intersegmental Coordination (ISC) to a new law for moments. It found that while elevation angles showed some coordination, Elevation Space Moments (ESM) lacked planarity in amputee gait compared to able-bodied individuals. This suggests poor coordination between the residual limb and prosthesis is linked to inefficient walking.
