Abstract

Objective

Physical therapy (PT) and botulinum toxin-A (BTX-A) injections are widely used in the treatment of spastic equinus foot due to cerebral palsy. The aim of this study was to show effects of intermittent serial casting (SC) in addition to standard treatment on spasticity, passive range of motion (PROM), and gait.

Design

Fifty-one ambulatory patients, treated by BTX-A to plantar flexor muscles, were randomly assigned to casting or control groups in a 2:1 ratio. Both groups received PT for 3 weeks. Casting group additionally received intermittent SC during 3 consecutive weekends. Assessments included Modified Ashworth Scale (MAS), Tardieu Scale, Observational Gait Scale (OGS), and Physician Global Assessment at baseline and posttreatment weeks 4 and 12.

Results

Significant improvements in PROM, MAS, Tardieu Scale, and OGS were recorded in both groups (P < 0.001 for all). Average changes in MAS, PROM, angle of catch, spasticity angle, and OGS of the casting group were significantly higher than those of the controls at week 4 (P = 0.006, P = 0.002, P < 0.001, P = 0.005, P = 0.011), and 12 (P = 0.013, P < 0.001, P < 0.001, P = 0.011, P < 0.001). Follow-up Physician Global Assessment also favored casting group (P < 0.001 for both).

Conclusions

Combining intermittent SC with BTX-A injections and PT might provide additional benefits for spastic equinus foot.
