To evaluate the most typical target muscles and dosages for the first and repeated botulinum toxin A (BTA) injections in cerebral palsy (CP) patients with severe motor deficit — GMFCS IV-V.
A retrospective analysis of 677 protocols of the first and repeated Abobotulinumtoxin A (AboA) injections in 333 patients with CP GMFCS IV and V, aged 1 to 18 years, was carried out.
Ninety-seven percent of patients received multilevel injections. In the lower extremities the most typical target muscles were: m.gracilis — 221 (66.4%) patients, hip adductors — 164 (49.2%), medial hamstring — 144 (43.2%). In the upper extremities the most typical muscles were: m.pronator teres — 237 (71.2%) patients, m.biceps brachii+m.brachialis — 197 (59.2%). The total dosages of AboA and dosages for every target muscle were calculated. Several patients required high dosages (more than 30 U/kg of AboA). Higher dosages per kg were used in younger children and for repeated injections. The age-related evolution of spastic patterns was described. Adverse events were observed in 36 cases (5.3% of all injections).
The majority of patients with GMFCS IV-V required multilevel BTA injections in high dosages, especially in young age. Described selection of target muscles and dosages of AboA could be taken into account as a practical experience and reference for the BTA therapy in GMFCS IV-V patients.
