Abstract:
We report a 61-year-old Parkinson's disease patient presenting with severe repetitive speech phenomena after deep brain stimulation. On admission, he showed impaired loudness, rough hoarseness, monoloudness and monopitch. It had been difficult for him to converse because of voice repetitive speech phenomena since 57 years of age. Medical control, regulation of contact location and voltage amplitude did not improve these symptoms. Lee Silverman Voice Treatment(®) improved loudness and voice quality, but did not improve repetitive speech phenomena. After speech treatment with a pacing board, his repetitive speech phenomena improved more than before. Treatment with a pacing board may be effective for repetitive speech phenomena in Parkinson's disease after deep brain stimulation.
