A writing device improves writing in primary writing tremor.
Primary writing tremor (PWT) is task-specific and interferes with handwriting. Several reports have shown a beneficial response of this disorder to stereotactic functional neurosurgery. Significant improvement with a writing device was demonstrated with blind rating of handwriting and spiral drawing samples collected before and during its use in nine patients with PWT, suggesting that this therapeutic modality should be tried before considering chronic pharmacotherapy or functional neurosurgery.
