BackgroundThe mechanisms underlying respiratory function impairments in different motor subtypes of Parkinson's disease (PD) remain poorly understood.ObjectivesThis study aims to elucidate the differences in respiratory function between the two main PD motor subtypes, tremor-dominant (TD) and postural instability gait difficulty (PIGD), and investigate their associations with disease severity.MethodsA total of 106 PD patients (59 TD and 47 PIGD) and 42 age- and sex-matched healthy controls (HCs) were enrolled. Pulmonary function tests (PFTs), respiratory muscle strength, and respiratory drive measurements were conducted. Multivariate models were employed to analyze correlations between respiratory function indices and clinical characteristics.ResultsCompared to HCs, PIGD patients exhibited significant reductions in forced vital capacity (FVC%) (P = 0.018), peak expiratory flow (PEF%) (P ConclusionsCompared to TD patients, PIGD patients have more pronounced respiratory impairments. Specific respiratory indices correlate with motor severity and cognitive decline, highlighting their potential as markers for disease progression in PD motor subtypes.
