Deep Brain Stimulation for Medication-Refractory Essential Tremor in a Musician Unable to Continue Performing

Condition

The patient, a professional classical guitarist, first noticed a fine tremor in both hands roughly eight years before presenting to Dr. Guruprasad Hosurkar, a Neurologist in Bangalore with a focused practice in tremor and Deep Brain Stimulation. The tremor was minimal at rest but became pronounced during sustained finger positioning and rapid string work, exactly the movements his performances depended on.

Over several years the tremor worsened. Bowing precision (in an earlier period of violin study) and later fretting-hand accuracy on the guitar both deteriorated. Handwriting became irregular, and pouring liquids or using cutlery in public became a source of visible embarrassment. He was treated sequentially with propranolol and primidone, and later a trial of topiramate, without meaningful benefit. Botox injections at another centre offered only brief, partial relief and mildly weakened grip strength, which further limited his playing.

By the time he was referred for a movement disorders opinion, the tremor had become disabling enough that he had stopped accepting performance engagements and had reduced his teaching load, relying on senior students to demonstrate difficult passages.

Emotional and Psychological Impact

Music had been the patient’s primary professional identity for over three decades, and the gradual loss of fine control eroded both his income and his sense of self. He described increasing anxiety before any task requiring precise hand movement, and a growing reluctance to be seen playing in front of colleagues or students. The initial consultation addressed this directly: clarifying that his tremor was a well-characterised, treatable neurological condition rather than a sign of general decline, and setting a realistic expectation that surgery could restore, not just stabilise, his functional hand control.

Why This Approach Was Chosen

The tremor was bilateral, action-predominant, and worsened with sustained fine motor use, a pattern consistent with essential tremor rather than a resting, Parkinsonian tremor. He had already failed adequate trials of first-line and second-line medications, and the tremor caused clear, significant functional disability in a task that depended entirely on manual precision. This combination, disabling tremor, refractory to pharmacological therapy, and suitability for stereotactic neurosurgery, met accepted criteria for Deep Brain Stimulation targeted at the ventral intermediate nucleus (VIM) of the thalamus. Occupational therapy for fine motor and instrument-specific retraining was planned from the outset, since medication and stimulation reduce tremor but relearning precise, performance-level control also requires structured practice.

“In musicians and other precision-dependent professionals, essential tremor is often dismissed early as nerves or fatigue, and by the time it is correctly identified, the functional loss is already significant. Once a tremor is confirmed as action-predominant and refractory to adequate medication trials, VIM thalamic DBS is one of the most reliable ways we have to give that fine control back.” — Dr. Guruprasad Hosurkar.
