Management of spasticity and dystonia in children with acquired brain injury with rehabilitation and botulinum toxin A

Abstract

Objective: To investigate the effect of a combination of botulinum toxin A (BTX-A) and rehabilitation on spasticity, pain and motor functioning in children with acquired brain injury (ABI).Methods: All children and adolescents with ABI, aged 2–20 years, consecutively treated in the department over a 22-month period, were prospectively followed-up and clinically assessed pre- and post-treatment. They had spasticity and/or dystonia leading to impairment in activities of daily living, orthopaedic deformations and/or pain. Injections were performed using electro-stimulation. Doses of BTX-A (Botox®) were administered using recent recommendations.Results: Twenty-five children (mean age 6.3 years) participated in the study (51 injection sessions). All patients received BTX-A injections, followed with physical and/or occupational therapy. Significant improvement was achieved for spasticity reduction (p < 0.0001), command on antagonist muscles (p = 0.03 for the tibialis anterior) and goniometry assessment (p < 0.05). Pain relief was achieved in patients in a minimally responsive state. Functional goals were achieved, such as improving transfers or gait, grasping and releasing abilities, with significant transfer in activities of daily living (p < 0.0001).Conclusion: A combination of BTX-A injection with rehabilitation is an interesting option for treatment of muscle tone disorders in children with ABI.
