OnabotulinumtoxinA muscle injection patterns in adult spasticity: a systematic literature review.

ABSTRACT:

Background

OnabotulinumtoxinA has demonstrated significant benefit in adult focal spasticity. This study reviews the injection patterns (i.e., muscle distribution, dosing) of onabotulinumtoxinA for treatment of adult spasticity, as reported in published studies.

Methods

A systematic review of clinical trials and observational studies published between 1990 and 2011 reporting data on muscles injected with onabotulinumtoxinA in adult patients treated for any cause of spasticity.

Results

28 randomized, 5 nonrandomized, and 37 single-arm studies evaluating 2,163 adult patients were included. The most frequently injected upper-limb muscles were flexor carpi radialis (64.0% of patients), flexor carpi ulnaris (59.1%), flexor digitorum superficialis (57.2%), flexor digitorum profundus (52.5%), and biceps brachii (38.8%). The most frequently injected lower-limb muscles were the gastrocnemius (66.1% of patients), soleus (54.7%), and tibialis posterior (50.5%). The overall dose range reported was 5-200 U for upper-limb muscles and 10-400 U for lower-limb muscles.

Conclusions

The reviewed evidence indicates that the muscles most frequently injected with onabotulinumtoxinA in adults with spasticity were the wrist, elbow, and finger flexors and the ankle plantar flexors. OnabotulinumtoxinA was injected over a broad range of doses per muscle among the studies included in this review, but individual practitioners should be mindful of local regulatory approvals and regulations.

Project description:Introduction: Spasticity is the main complication of many upper motor neuron disorders. Many studies describe neuro-orthopedic surgeries for the correction of joint and limb deformities due to spasticity, though less in the upper extremity. The bulk of care provided to patients with spasticity is provided by rehabilitation clinicians, however, few of the surgical outcomes have been summarized or appraised in the rehabilitation literature. Objective: To review the literature for neuro-orthopedic surgical techniques in the upper limb and evaluate the level of evidence for their efficacy in adult patients with spasticity. Method: Electronic databases of MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews were searched for English, French as well as Farsi languages human studies from 1980 to July 2, 2020. After removing duplicated articles, 2,855 studies were screened and 80 were found to be included based on the criteria. The studies were then divided into two groups, with 40 in each trial and non-trial. The results of the 40 trial articles were summarized in three groups: shoulder, elbow and forearm, and wrist and finger, and each group was subdivided based on the types of intervention. Results: The level of evidence was evaluated by Sackett's approach. There were no randomized control trial studies found. About, 4 studies for shoulder, 8 studies for elbow and forearm, 26 studies for wrist and finger (including 4 for the thumb in palm deformity), and 2 systematic reviews were found. Around, two out of 40 trial articles were published in the rehabilitation journals, one systematic review in Cochrane, and the remaining 38 were published in the surgical journals. Conclusion: Most surgical procedures are complex, consisting of several techniques based on the problems and goals of the patient. This complexity interferes with the evaluation of every single procedure. Heterogenicity of the participants and the absence of clinical trial studies are other factors of not having a single conclusion. This review reveals that almost all the studies suggested good results after the surgery in carefully selected cases with goals of reducing spasticity and improvement in function, pain, hygiene, and appearance. A more unified approach and criteria are needed to facilitate a collaborative, evidence-based, patient referral, and surgical selection pathway.

Project description:BackgroundOnabotulinumtoxinA is approved as a treatment across multiple indications. For the treatment of spasticity, onabotulinumtoxinA is injected directly into affected muscles. Intramuscular injections may result in local bleeding and related complications, especially in patients receiving anticoagulant therapy. Despite anticoagulants being commonly used, there is limited information in the medical literature regarding the safety of intramuscular medications in patients receiving oral anticoagulants. This retrospective analysis included pooled safety data from Allergan-sponsored studies evaluating onabotulinumtoxinA for the treatment of patients with muscle spasticity.ObjectiveThe objective of this study was to determine the risk of bleeding complications in patients with post-stroke spasticity receiving antithrombotic therapy and intramuscular onabotulinumtoxinA.MethodsWe conducted a retrospective analysis of pooled safety data from 16 randomized, double-blind, placebo-controlled Allergan-sponsored studies of onabotulinumtoxinA for the treatment of post-stroke upper or lower limb muscle spasticity, including adult patients with at least moderate upper or lower limb spasticity and receiving at least one dose of the study drug. Bleeding-related adverse events starting within 4 weeks of study treatment were assessed. The incidence rates of bleeding complications were compared for patients receiving classes of antithrombotic therapy vs those not receiving antithrombotic therapy and for those receiving onabotulinumtoxinA vs placebo (with or without antithrombotic therapy).ResultsOf 1877 patients, 1182 received antithrombotic therapy. The overall incidence of bleeding complications was < 2%. In those receiving any antithrombotic therapy, the incidence of bleeding was 1.0% vs 1.4% (no antithrombotic therapy); after onabotulinumtoxinA, it was 0.9% for those receiving antithrombotic therapy vs 1.4% (no antithrombotic therapy), and for placebo 1.2% vs 1.4%, respectively. Subgroup results were similar.ConclusionsNo apparent increased risk of bleeding complications was observed following administration of onabotulinumtoxinA to patients receiving antithrombotic therapy. Nonetheless, patient education and careful observation of the injection site in patients receiving antithrombotic therapy remains warranted.
