RESUMEN
BACKGROUND: Cerebral Palsy (CP) is a group of permanent, but not unchanging, disorders of movement and/or posture and motor function, which are due to a non-progressive interference, lesion, or abnormality of the developing/immature brain. One clinical presentation is muscle spasticity, which leads to a significant impact on the individual's functionality and quality of life. Spasticity treatment is multidisciplinary and includes pharmacological and physical intervention; intrathecal baclofen shows a positive effect in severe spasticity and suboptimal response to oral drugs, while local injection of Botulinum toxin type A (BTXA) improves muscle tone, motion and pain. OBJECTIVE: The aim of this study was to evaluate the efficacy of the combined intrathecal baclofen infusion (ITB) - botulinum toxin treatment in the management of spasticity in CP. METHODS: 8 patients with spastic tetraparesis were enrolled. All patients were treated with intrathecal Baclofen; in lower limbs, no spastic symptoms appeared, while marked spasticity was noted in upper limbs. We injected the right and left Biceps Brachial (BB) and Flexor Digitorum Superficialis (FDS) muscles with botulinum toxin type A. All patients underwent Myometric measurement, Ashworth Scale, Numerical Rating Scale, and Visual Analogic Scale evaluation before infiltration (T0), 30 days after injection (T1), 60 days after injection (T2), and 90 days after treatment (T3). RESULTS: All data demonstrated an improvement in spasticity, pain, quality of life, and self-care during the study, with p < 0.05. No side effects appeared. CONCLUSION: This study demonstrated the efficacy and safety of intrathecal baclofen infusion and botulinum toxin combined treatment in the management of spasticity, pain, quality of life, and selfcare in CP patients.

BACKGROUND: Many studies in vitro compared the onset of action, maximum efficacy, and duration of botulinum toxin type A (BoNT/A) preparations. OBJECTIVE: In this study, we analyzed the onset of action of BoNT/A preparation free of complexing proteins in patients with upper limb spasticity post stroke up to 30 days after treatment. METHODS: 75 patients affected by Biceps Brachii spasticity were enrolled. Outcome measures were instrumental muscle tone modification (myometric measurement), improvement of Modified Ashworth Scale (MAS), improvement of elbow's passive extension, and improvement of compound muscle action potential (cMAP) evaluated by electroneurography. We analyzed data at t0 (pre-injection), t1 (1 day after), t2 (7 days after), t3 (14 days after), and t4 (30 days after). RESULTS: All measurements decreased at t2, t3, and t4 with initial improvement at t2 and maximum improvement at t4; no statistical difference at t1 was found. CONCLUSION: This study demonstrated the onset of Incobotulinumtoxin A efficacy started after 7 days; this rapid action and efficacy of BoNT/A preparation could improve an intensive rehabilitation program after some days post-injection. Early clinical onset of action could be by the absence of complexing proteins in the preparation.
