When essential tremor persists despite conventional management, a targeted procedural approach is available. This protocol addresses tremor affecting the limbs, head, or voice in cases that have not responded adequately to prior treatment.
This protocol applies to medically refractory essential tremor — cases where ongoing tremor in one or more regions (limb, head, or voice) continues to impair function after standard measures.
The approach centres on Botulinum Toxin-A injections delivered directly into the muscles responsible for generating the tremor. Guidance techniques are used to improve the accuracy of muscle selection.
In medically refractory cases of ET, injections of Botulinum Toxin-A in the tremorogenic muscles (preferably under electromyographic guidance for selecting the muscles) may be useful.
The injection has been shown to be useful for limb, head, and voice tremor.
