Study type | Interventional |
In children with cerebral palsy, stiffness of the arm can develop early and delay or prevent the acquisition of normal hand skills. Improvement in functional use of the hand may therefore be dependent upon early treatment of upper extremity hypertonia. We propose to test a series of injections of Myobloc™ in a non-randomized one-way crossover pilot clinical trial and dose-finding study, with clinical assessments and blinded video evaluations. Ten children age 2-17 years with increased tone at the elbow or wrist will be expected to complete the study. A 1-month baseline evaluation period will be followed by an injection of low-dose Myobloc™ to affected muscle(s) of the arm according to standardized per-kilogram dosing with a maximum of 25U/kg in each affected arm. Three months later, a second injection of up to 50U/kg will be performed in each affected arm. Three months after the second dose, a third dose of up to 100U/kg will be performed in each affected arm. Neurological assessments will be performed at study entry, prior to each injection, and at 1 and 3 months following each injection. Routine physical therapy and non-study medications will be continued during the study.

Eligibility |
Inclusion Criteria: - 1. Age 2- 17 years 2. Hypertonia affecting one or both upper extremities 3. Hypertonia caused by static encephalopathy due to prenatal or perinatal injury 4. Cognitive and motor function sufficient so that the child will reliably reach toward a target or a small toy 5. Concurrent enrollment in “standard of care” physical therapy or occupational therapy services Exclusion Criteria: - 1. Injection of neuromuscular blocking agents to any extremity within six months prior to enrollment 2. Dose changes of trihexyphenidyl, dantrolene, baclofen, dopaminergic agents or benzodiazepines during the course of the study. 3. Any use of aminoglycoside antibiotics during the study. 4. Prior surgery to either upper extremity 5. Initiation or change in physical or occupational therapy regimen within 3 months of study entry 6. Progressive or neurodegenerative disease, or suspicion of an inborn error of metabolism 7. Neuropathy, myopathy, or neuromuscular junction disease 8. Congenital deformities of either upper extremity 9. Respiratory or airway compromise, or use of respiratory medications 10. Cardiomyopathy 11. Any other medical condition that would place the child at risk for participation |
