The respiratory problems that older adults with PD present
reflect the compromised values of present
reflect the compromised values of PImax and PEmax, and
result in situations of obstruction of the upper airways,
restrictive disorders, and complications arising from aspiration.23
Mehanna and Jankovic24 hypothesized that the
respiratory dysfunctions in PD may be the result of muscle
dystonia causing abnormal rhythmic oscillations in the supraglottic
structures.
