Abstract

Definition: Isoperceptual Manifold (IPM) is the combination of sensory inputs that covary to achieve a single perceptual goal

• → e.g. to hold a cup: perception from 3 fingers combine into a singular perceived force.

Background: IPM known to exist in upper extremities,¹ but IPM has not been examined in lower extremity (LE) loading.

Theory: IPM influenced by stance width might contribute to postural control instability^2,3
