From: Impaired foot placement strategy during walking in people with incomplete spinal cord injury
Actual mediolateral (ML) foot placement versus predicted ML foot placement of a person with incomplete spinal cord injury (iSCI) walking in the self-paced condition (A) and of a healthy control walking in the self-paced condition (B) and the fixed-speed 50% condition (C). RMSE indicates the root mean square error between the actual and predicted foot placements, referred to as foot placement deviation. R2 indicates the coefficient of determination of the fit, referred to as the foot placement adherence
