Abstract
To assess the efficacy of intermittent serial casting in conjunction with occupational therapy and botulinum neurotoxin A (BoNT-A) in children with cerebral palsy (CP) presenting spastic wrist flexion deformity. This was a controlled, prospective study in which 34 children (19 females, 15 males; mean [SD] 11y [4y 6mo]) were randomly allocated to casting or control groups in a ratio of 2:1. Both groups were subjected to BoNT-A treatment and occupational therapy. The casting group additionally received a series of progressive casts intermittently for three consecutive weekends. Outcome measures consisted of passive range of motion (PROM) as assessed by goniometer, muscle tone by Modified Ashworth scale (MAS), and spasticity by Tardieu Scale. Assessments were done at baseline, week 4, and week 12. Baseline characteristics of casting and control groups were comparable. PROM, MAS, and Tardieu angle of catch (XV3) of the casting and control groups significantly improved after treatment (p<0.001 for all). Nevertheless the mean change from baseline MAS at week 12, mean changes from baseline PROM, Tardieu XV3, and the spasticity grade (Y) at week 4 and week 12 of the casting group showed statistical superiority over those of the control group (p<0.05 for all). Children with CP presenting spastic wrist flexion deformity might gain additional benefits from supplementary intermittent serial casting as well as BoNT-A injections and occupational therapy. Serial casting could be considered as a complementary treatment to BoNT-A and occupational therapy in children with clinically significant PROM limitations.
