The objective of the present study was to evaluate the effectiveness and tolerability of incobotulinumtoxinA, at doses according to individual needs, in 10 patients with acquired brain injury and severe upper and lower limb spasticity. Patients received a multipattern periodic treatment with ultrasound-guided injections of incobotulinumtoxinA at doses of 800-900 U in the upper and lower limbs. The mean number of injection cycles per patient was 4.2. The 0-10 visual analogue scale for pain score decreased significantly from pre-injection (mean: 4.7) to four-week post-injection (mean: 0.7). Similarly, the mean Ashworth Scale score (muscular tone assessment) at four-week post-injection (mean: 1.4) was significantly lower than at injection (mean: 2.5). Except for two patients in one pattern, all cases showed an improvement in passive range of motion assessments using goniometry. All patients reported maximum satisfaction with the treatment, all reporting “much improved” after the treatment. No treatment-related adverse effects were observed during the study. Individualized doses of incobotulinumtoxinA are effective and well-tolerated for this type of patients and allow better management of their severe spasticity. Therefore, individualization of doses should be taken into account for optimizing clinical outcomes and improving the patients’ treatment satisfaction.
