Flexed Posture in Parkinson Disease: Associations With Nonmotor Impairments and Activity Limitations

People with Parkinson disease (PD) are twice as likely to develop flexed truncal posture as the general older population. Little is known about the mechanisms responsible beyond associations with age, axial motor impairments, and disease severity.The objective was to explore: (1) the associations of the nonmotor impairments of PD with flexed posture, and (2) the relationships of flexed posture with activity limitations.This was a cross-sectional...
