Abstract

The relationship between length and electrical activity of lower extremity muscles was studied in cerebral palsy patients before and after lengthening for crouch gait. Patients with cerebral palsy crouch gait were studied pre-operatively and one year post-operatively by three-dimensional kinematic analysis. Dynamic EMG of representative muscles was performed pre-operatively. A computer model allowed calculation of the length variations of 26 major lower extremity muscles during walking. The model included origin and insertion of the muscles as well as adjustment for 'pullys' when muscle action did not follow a straight line.
