Trial Registration Clinical Trials Registry of India ( ) Identifier: CTRI/2021ĭystonia is a movement disorder characterized by abnormal involuntary sustained posturing of 1 or more body parts. An individualized approach to muscle selection and dosing was beneficial without unacceptable adverse effects. Subjective hand weakness (BoNT: 6 placebo: 4, P = .52) and dynamometer-assessed grip strength (mean difference, –0.2 log 10 2/Hz-Hz 95% CI, –0.9 to 0.4 log 10 2/Hz-Hz P = .45) were similar in both groups.Ĭonclusions and Relevance In this randomized clinical trial, botulinum neurotoxin injections were superior to placebo in reducing tremor severity in upper-extremity DT. More participants in the BoNT group reported global improvement on the Global Impression of Change (PGIC) assessment (PGIC 1, 2, and 3: BoNT: 4, 6, and 5 placebo: 5, 10, and 0, respectively P = .047). In the intention-to-treat group, the Fahn-Tolosa-Marin Tremor Rating Scale total score was significantly lower in the BoNT group at 6 weeks (adjusted mean difference, –10.9 95% CI, –15.4 to –6.5 P < .001) and 12 weeks (adjusted mean difference, –5.7 95% CI, –11.0 to –0.5 P = .03). Fifteen were ineligible and 3 refused consent therefore, 30 patients (mean age, 46.0 years 26 male) were recruited, with 15 randomized to receive BoNT and 15 to receive placebo. Results A total of 48 adult patients with a diagnosis of brachial dystonia with DT were screened. All patients were offered open-label BoNT injections after 12 weeks and reassessed 6 weeks later. Outcomes were assessed at baseline, 6 weeks, and 12 weeks. Main Outcomes and Measures The primary outcome was the total score on the Fahn-Tolosa-Marin Tremor Rating Scale 6 weeks after the intervention. Injection patterns and doses were individualized according to tremor phenomenologic findings. Interventions Participants received electromyographically guided intramuscular injections of BoNT or placebo into the tremulous muscles of the upper extremity. Participants were recruited between November 20, 2018, and December 12, 2019, and the last follow-up was completed in March 2020. The participant, injector, outcome assessor, and statistician were blinded to the randomization. Randomization was masked using opaque envelopes. Objective To assess the effect of BoNT injections on tremor in patients with upper-extremity DT.ĭesign, Setting, and Participants In this placebo-controlled, parallel-group randomized clinical trial, 30 adult patients with upper-extremity DT treated at a movement disorder clinic in a tertiary care university hospital were randomized in a 1:1 ratio to BoNT or saline injection, 0.9%, using a computer-generated randomization sequence. Fahn tolosa marin tremor rating scale pdf file series#To date, only uncontrolled retrospective case series have reported the effect of botulinum neurotoxin (BoNT) injections on upper-extremity DT. Importance There is an unmet need for safe and efficacious treatments for upper-extremity dystonic tremor (DT).
