Residual signal auto-correlation to evaluate speech in Parkinson's disease patients

Objective: To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients. Method. The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender. Resu...

Method. The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender. Results: Statistical difference was seen between groups for PA, 0.39 for controls and 0.25 for PD. Normal value threshold was set as 0.3; (p <= 0.001). In the Parkinson's group 80.77%, and in the control group only 12.28%, had a PA < 0.3 demonstrating an association between these variables. The dispersion diagram for age and PA for PD individuals showed p=0.01 and r=0.54. There was no significant difference in relation to gender and PA between groups: Conclusion: the significant differences in pitch's amplitude between PD patients and healthy individuals demonstrate the methods specificity.-The results showed the need of prospective controlled studies,to improve the use and indications of residual signal auto-correlation to evaluate speech in PD patients.Univ São Paulo, Sch Engn, São Paulo, BrazilUNESP, Sch Med Botucatu, São Paulo, BrazilHosp UNESP, Botucatu, SP, BrazilUniv São Paulo, Sch Engn, BR-13560 Sao Carlos, BrazilUniv Estadual Paulista Julio Mesquita Filho, Biosci Sch, Botucatu, SP, BrazilUNESP, Sch Med Botucatu, São Paulo, BrazilHosp UNESP, Botucatu, SP, BrazilUniv Estadual Paulista Julio Mesquita Filho, Biosci Sch, Botucatu, SP, BrazilAssociação Arquivos de Neuro- PsiquiatriaUniversidade de São Paulo (USP)Universidade Estadual Paulista (Unesp)2014-05-20T15:29:53Z2014-05-20T15:29:53Z2006-12-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article912-915application/pdfhttp://dx.doi.org/10.1590/S0004-282X2006000600004Arquivos de Neuro-psiquiatria.
