Abstract

The purpose of this study was to assess whether there is an improvement in motor function in persons with cerebral palsy (CP) who have had a reduction of muscle tone by continuous intrathecal baclofen infusion. This was a prospective, open label, non-blinded case series without a control group, conducted at multiple centres. There were 31 subjects, aged 4-29 years. All had a pre-treatment mean lower extremity Ashworth scores of ≥ 3 and a significant reduction in tone after a bolus injection of intrathecal baclofen (ITB) and received an implanted pump for continuous delivery of ITB. Motor function was assessed by the Gross Motor Function Measure (GMFM) prior to and 1 year following pump implantation. Significant improvement (p < 0.05) in mean GMFM scores was seen in subjects < 8 years (mean change 4.1) and in those from 8-18 years (mean change 3.7) and in subjects with CP Classes 2 and 5 (mean changes 6.2 and 2.9). There was a statistically significant decrease (p < 0.05) in Ashworth scores in CP classes 2-5. Subjects or their caregivers that completed a survey about perceived changes stated that motor control, positioning and endurance improved.
