Pediatric Physical Therapy published a research article on assessments following botox injections and casting to treat equinus gait in 10 children with cerebral palsy (ages 26-75 months) .  Pre- assessments and post assessments (one week following cast removal) were performed.  Improvements were seen on the Modified Ashworth Scale, Modified Tardieu Scale and PEDI (in mobility, self care and social function).   Gait analysis revealed slower cadence and speed.  The researchers recommend raising the minimum age and to delay gait analysis.
