Background And Purpose: Guided self-rehabilitation contracts (GSCs) are a diary-based rehabilitation strategy, wherein specific muscles are identified for prescription of high-load, home self-stretching techniques. We assessed the effect of GSCs combined with simultaneous upper limb (UL) and lower limb (LL) abobotulinumtoxinA injections on composite active range of motion (CXA) in adults with chronic spastic paresis.

Methods: This was an international, prospective, single-arm, open-label study (ENGAGE, NCT02969356).

Aim Of The Study: SPACE, a prospective, non-interventional, open-label, multinational study, investigated physicians' and subjects' assessment of safety, efficacy, and health-related quality of life (HRQoL) following botulinum neurotoxin type A (BoNT-A) treatment to understand real-world clinical usage for the management of focal and multifocal spasticity.

Clinical Rationale For The Study: Treatment guidelines recommend the use of BoNT-A for the management of spasticity in adults. This study assessed how physicians use BoNT-A therapy in real-world clinical practice, and provided evidence on long-term safety and efficacy over a period of up to 2 years.

Botulinum toxins, such as abobotulinumtoxinA, are used to treat spasticity (muscle overactivity) in arm muscles. Spasticity in shoulder muscles occurs in many patients following a stroke. Shoulder spasticity can be painful and limit limb movement.

Objective: To compare walking speed in patients with spastic hemiparesis who received abobotulinumtoxinA either in the lower limb or simultaneously in both the lower and upper limbs.

Design: Post hoc analysis from a phase 3 study of abobotulinumtoxinA (Dysport®, NCT01251367).

Patients: Adult patients with spastic hemiparesis causing gait dysfunction.

Objective: To demonstrate single abobotulinumtoxinA injection efficacy in lower limb vs placebo for adults with chronic hemiparesis and assess long-term safety and efficacy of repeated injections.

Methods: In a multicenter, double-blind, randomized, placebo-controlled, single-cycle study followed by a 1-year open-label, multiple-cycle extension, adults ≥6 months after stroke/brain injury received one lower limb injection (abobotulinumtoxinA 1,000 U, abobotulinumtoxinA 1,500 U, placebo) followed by ≤4 open-label cycles (1,000, 1,500 U) at ≥12-week intervals. Efficacy measures included Modified Ashworth Scale (MAS) in gastrocnemius-soleus complex (GSC; double-blind primary endpoint), physician global assessment (PGA), and comfortable barefoot walking speed.

Background: This study evaluates the effect of incobotulinumtoxinA in the acute and chronic phases of facial nerve palsy after neurosurgical interventions.

Methods: Patients received incobotulinumtoxinA injections (active treatment group) or standard rehabilitation treatment (control group). Functional efficacy was assessed using House-Brackmann, Yanagihara System and Sunnybrook Facial Grading scales, and Facial Disability Index self-assessment.

Article Synopsis
  • The study evaluated the effectiveness and safety of abobotulinumtoxinA in adults with upper limb spasticity who had previously received other botulinum toxin treatments.
  • At week 4, a significantly higher percentage of participants receiving abobotulinumtoxinA showed improvement in muscle tone and overall function compared to those given a placebo.
  • No serious adverse events or deaths were reported, indicating that abobotulinumtoxinA is a safe option for treating this condition.

Background: Resistance from antagonistic muscle groups might be a crucial factor reducing function in chronic hemiparesis. The resistance due to spastic co-contraction might be reduced by botulinum toxin injections. We assessed the effects of abobotulinumtoxinA injection in the upper limb muscles on muscle tone, spasticity, active movement, and function.

Cervical dystonia is a neurological movement disorder causing abnormal posture of the head. It may be accompanied by involuntary movements which are sometimes tremulous. The condition has marked effects on patients' self-image, and adversely affects quality of life, social relationships and employment.
