Insights
Botulinum-A toxin (BTA) injections improved upper extremity function and self-care skills in children with spastic hemiplegia. This treatment, combined with occupational therapy, offers a promising option for managing this condition.
Area of Science:
- Pediatric Neurology
- Rehabilitation Medicine
- Movement Disorders
Background:
- Spastic hemiplegia in children significantly impacts upper extremity function and daily activities.
- Botulinum-A toxin (BTA) is a neurotoxin used to reduce muscle spasticity.
- Effective interventions are needed to improve functional outcomes in affected children.
Purpose of the Study:
- To evaluate the efficacy of botulinum-A toxin (BTA) injections in improving upper extremity function in children with spastic hemiplegia.
- To compare outcomes between children receiving BTA injections plus occupational therapy and those receiving occupational therapy alone.
Main Methods:
- A randomized, controlled, single-blind trial involving 30 children (aged 2.5-10 years) with hemiplegia.
- Participants were assigned to either BTA injections (targeting biceps, forearm, or thumb muscles) plus occupational therapy, or occupational therapy alone.
- Outcomes measured included the Quality of Upper Extremity Skills Test (QUEST), goniometry, grip strength, Ashworth scores, and the Pediatric Evaluation of Disability Inventory (PEDI) self-care domain.
Main Results:
- The group receiving BTA injections showed a statistically significant improvement in the QUEST scores compared to the control group (P=.039).
- Significant improvements were also observed in the self-care domain of the PEDI for the BTA treatment group (P=.04).
- Twenty-nine of thirty participants completed the study.
Conclusions:
- Botulinum-A toxin injections, when combined with occupational therapy, are effective in enhancing upper extremity function in children with spastic hemiplegia.
- The findings support BTA as a valuable therapeutic option for children with moderate to severe spasticity affecting their upper limbs.
Objective:
In a randomized, controlled, single-blind trial, to test the hypothesis that botulinum-A toxin (BTA) injections into the upper extremity of children with spastic hemiplegia improve upper extremity function.
Study Design:
Thirty children with hemiplegia, aged 2.5 to 10 years, were randomly assigned to receive: (1) a BTA injection into 1 or more of 3 muscle groups (biceps, volar forearm muscles, adductor pollicis) plus occupational therapy or (2) occupational therapy alone. Blinded outcomes obtained at baseline and at 1, 3, and 6 months included the Quality of Upper Extremity Skills Test (QUEST), goniometry measurements, grip strength, and Ashworth scores. The caregiver completed the self-care domain of the Pediatric Evaluation of Disability Inventory.
Results:
Twenty-nine subjects completed the study. The QUEST demonstrated a significant improvement favoring the treatment group on a 2-way analysis of variance (F = 4.69, df = 1,83; P =.039). BTA treatment was also associated with an improvement in score on the self-care domain of the Pediatric Evaluation of Disability Inventory (F = 4.68, df = 1,82; P =.04).
Conclusions:
This study supports the effectiveness of BTA injections to improve upper extremity function of children with hemiplegia who have at least moderate spasticity.
