ABSTRACT

AIM: To assess the safety and clinical and neurophysiological efficacy of xeomin in children with spastic equinus and equinovarus foot deformity in cerebral palsy. MATERIAL AND METHODS: Sixty-four patients with spastic forms of cerebral palsy (levels I-IV on the GMFCS) were enrolled into this multi-center open-label comparative randomized trial. The patients were administered xeomin or botox once, each drug being administered to 32 patients. Efficacy was evaluated based on clinical characteristics (the modified Ashworth scale, goniometry) and electromyography data. The subjects were observed for 3 months (90±7 days) after injections. The incidence, severity and intensity of adverse events (AE) was also determined. RESULTS: Treatment with xeomin according to the suggested protocol has proven its high clinical efficacy. The efficacy was demonstrated by significant, stable and long-term decrease in the gastrocnemius muscle tone: in the xeomin group, the score on the modified Ashworth scale decreased from 2.6±0.49 points at baseline to 1.8±0.54 points (р<0.000001, paired t-test; р<0.000004, Wilcoxon test). In the botox group, this score decreased from 2.4±0.56 points to 1.6±0.45 points (р<0.000001, paired t-test; р<0.000002, Wilcoxon test). The increased range of ankle joint movements at passive and voluntary feet extension. In the xeomin group, the significant proportion of patients (45.1%) moved to the group of lower spasticity defined as less than two score points on the modified Ashworth scale. The clinical data fully matched the changes in electromyography parameters, which were characterized by the lower amplitude and area of the target muscle (lateral and medial gastrocnemius heads) M-responses. AE developed in three patients (9.4%) administered xeomin and in two patients (6.3%) administered botox. The AE recorded in the study are described in the recommendations on the use of xeomin and botox. In three cases (50.0%), AE intensity was determined as mild, in the remaining three cases (50.0%) as moderate. CONCLUSION: The results have shown the safety and efficacy of xeomin in the treatment of gastrocnemius spasticity in pediatric patients with cerebral palsy. These data are confirmed by the lack of significant differences in any clinical or electromyography parameters with the results in the reference group administered botox.

ABSTRACT

Spasticity treatment is one of the key aspects of the contemporary cerebral palsy (CP) rehabilitation that influences on the effectiveness of other methods. The paper presents the first Russian document that unites the recommendations for the BTA treatment of CP and could be used as the guideline for the multilevel injections. The Russian consensus on the multilevel botulinum toxin A (BTA) treatment of spastic CP is based on the international data and the results of national studies. The authors describe typical CP spasticity patterns in the upper and lower extremities, give recommended intervals for the BTA (Abobotulinum toxin A) dosages for the whole injection procedure and for the separate muscles. The method of dosage calculation for functional segments is also described. Attention is paid to the frequency, optimal intervals between the repeated injections and the whole duration of BTA treatment. The authors discuss effectiveness and safety of BTA, factors that potentially influence the results of the injections, including ultrasound and electromyography control, and indications for the continuation and termination of treatment.

ABSTRACT

AIM: To analyze the efficacy and safety of dose ranges of abobotulinum toxin A (BTA) for multilevel injections into upper and lower extremity muscles in children with spastic forms of cerebral palsy (CP). MATERIAL AND METHODS: We analyzed retrospectively multilevel BTA injections for 216 patients, aged from 2 to 17 years. Children received 1-6 repeated injections and complex physiotherapy. Patients were classified according to the GMFCS. Treatment results were evaluated with the modified Ashworth and Tardieu scales. RESULTS: Multilevel BTA injections were indicated for the most (89/8%) of the patients with spastic forms of CP, and in most of them the total dosage exceeded 30 U/kg. In the bilateral forms of CP, the total dosage (U and U/kg) was higher compared to the unilateral forms. Doses for each muscle in U/kg were similar in all CP forms. The total doses of BTA and the intervals between the repeated injections were stable for each patient. CONCLUSION: The dose ranges suggested for CP are effective and safe for the reduction of spasticity in several functional segments of upper and lower extremities in one treatment session.
