Essential voice tremor: treatment with propranolol.
We studied chronic oral propranolol therapy and placebo in seven patients with essential voice tremor. Mean scores for voice tremor and voice quality did not differ for placebo or propranolol. Hand tremor amplitude decreased significantly with propranolol. Voice tremor seems to be more resistant to propranolol therapy than hand tremor.
