To assess the additive effect of adjuvant electrical stimulation on botulinum toxin A injection in children with spastic diplegic cerebral palsy.


Eighteen children with dynamic foot equinus deformity were treated with botulinum toxin A injection into the calf muscles. Seven children were assigned to a treatment group who received botulinum toxin A and adjuvant electrical stimulation, and 11 children were assigned to a control group with botulinum toxin injection only. Before botulinum injection, and at 2 wks and 3 mos after injection, the Physician Rating Scale, passive ranges of ankle and knee motion, and the modified Ashworth scale were measured.


A significant increase in passive range of ankle motion was observed at 2 wks after injection in the treatment group and at 3 mos after injection in both groups. Both groups showed significant improvements by the modified Ashworth scale at 2 wks after injection. Subscales of the Physician Rating Scale (equinus foot, crouched gait) and total Physician Rating Scale scores were significantly improved in the treatment group at 3 mos after injection, but this was not observed in the control group.


Adjuvant electrical stimulation for a short period after botulinum toxin A injection was found to benefit early improvement of range of motion and maintenance of gait improvement in children with spastic diplegia cerebral palsy showing dynamic equinus.
