Functional outcomes of multilevel botulinum toxin and comprehensive rehabilitation in cerebral palsy

Area of Science:

• Pediatric Rehabilitation
• Neuromuscular Disorders
• Movement Science

Background:

• Cerebral palsy (CP) is a common neurodevelopmental disorder affecting movement and posture.
• Spasticity in the lower extremities significantly impacts ambulatory function in children with CP.
• Multilevel botulinum toxin A injections offer a targeted approach to managing spasticity.

Purpose of the Study:

• To evaluate the efficacy of multilevel lower extremity botulinum toxin A injections and comprehensive rehabilitation in reducing spasticity.
• To assess the functional gains, including walking ability and gait quality, in ambulatory children with spastic cerebral palsy.
• To determine the correlation between reduced spasticity and improved functional outcomes.

Main Methods:

• A cohort of 16 ambulatory children (aged 3-8 years) with spastic cerebral palsy (GMFCS I-III) received multilevel botulinum toxin A injections in the lower extremities.
• Participants underwent a comprehensive rehabilitation program post-injection.
• Functional outcomes were measured using the Six-Minute Walk Test (walking distance and speed) and the Observational Gait Scale (video gait analysis).

Main Results:

• Significant improvements were observed in walking distance and walking speed as measured by the Six-Minute Walk Test.
• Gait quality, assessed by the Observational Gait Scale, showed significant improvement.
• Positive changes in muscle length, reduced spasticity, and improved muscle selectivity were recorded post-treatment.

Conclusions:

• Multilevel botulinum toxin A injections, coupled with comprehensive rehabilitation, effectively reduce lower extremity spasticity in ambulatory children with cerebral palsy.
• This combined therapeutic approach leads to clinically significant improvements in functional mobility and gait parameters.
• The findings support the use of botulinum toxin A and rehabilitation as a valuable intervention for enhancing functional abilities in pediatric CP populations.
