IntroductionDuring gait, many children with cerebral palsy have abnormal electromyographic activity of the rectus femoris during swing. This abnormal activity, caused by spasticity of the quadriceps musculature, has been thought to decrease sagittal plane knee motion during swing producing a stiff knee gait pattern. Gage and Perry noted that spastic rectus femoris activity beyond 15-20% of swing...
IntroductionChildren with spastic diplegia have increases in knee flexion during ambulation and there are several surgical procedures available to address this problem. These include hamstring lengthenings or transfers (Thometz 1989). Gage (1987) reports improved knee motion following a distal hamstring lengthening in conjunction with a distal rectus transfer. Sutherland (1990) reports similar results...
