The objective of this study was to investigate the relationships
between motor symptoms of Parkinson disease (PD) and activity limitations in
persons with PD. METHODS:
This is a cross-sectional study of persons with
mild to moderate PD (N = 90). Associations among axial motor features, limb motor
signs, the Physical Activity Scale for the Elderly, the ability to perform
Activities of Daily Living (ADLs), and level of ADL dependency were studied. A composite score of axial motor features included the following Unified Parkinson
Disease Rating Scale items: speech, rigidity of the neck, arising from chair,
posture, gait, and postural stability. A composite score of limb motor signs
included the following Unified Parkinson Disease Rating Scale items: tremor at
rest of all extremities, action tremor, rigidity of all extremities, finger taps,
hand movement, rapid alternating hand movements, and foot tapping. RESULTS: Axial
motor features of PD were significantly correlated with physical inactivity (P <
0.001), decreased ADL (P < 0.001), and increase in ADL dependency (P < 0.001).
Limb motor signs significantly correlated with decreased ADL (P < 0.001) and
level of ADL dependency (P = 0.035) but did not correlate with physical
inactivity. After controlling for age, sex, disease duration, and comorbidity,
axial motor features contributed significantly to physical inactivity, decreased
ADL, and increase in ADL dependency, whereas the limb motor signs did not.
CONCLUSIONS: Axial motor impairment contributed to physical inactivity and
decreased ability to perform ADLs in persons with PD.
