PURPOSE: To check the findings on respiratory muscular strength (RMS), body posture (BP), vocal intensity (VI) and maximum phonation time (MPT), in patients with Parkinson Disease (PD) and control cases, according to gender, Parkinson Disease stage (PD) and the level of physical activity (PA). METHODS: three men and two women with PD, between 36 and 63 year old (study cases - SC), and five subjects without neurologic diseases, of the same age, gender and PA level (control cases - CC). We evaluated RMS, BP, VI and MPT. RESULTS: men: a more pronounced decrease of MPT, VI, RMS in Parkinson patients, plus postural alterations in the elderly; women: similar postural alterations, positive relation between stages, PA level and the other measures. CONCLUSIONS: We observed in women with PD, impaired VI; in men with PD deficits in MPT, VI, RMS. We suggest further studies under an interdisciplinary bias.
