From: Home and health in people ageing with Parkinson’s disease: study protocol for a prospective longitudinal cohort survey study

ICF (WHO, 2001)
  • Personal factors: e.g. sex, age, coping, self-efficacy
  • Body functions: e.g. motor and cognitive symptoms, pain
  • Activity: e.g. activities of daily living (ADL), walking
  • Participation: e.g. recreation and leisure, social interactions
  • Environmental factors: e.g. physical environmental barriers, assistive products and technology, support by others, and relationships
P-E fit and perceived aspects of home
  • Personal component (P): functional limitations and dependence on mobility devices
  • Environmental component (E): physical environmental barriers
  • Perceived aspects of home: housing satisfaction, usability of the home, meaning of home and housing-related control beliefs
PD-specific aspects/problems
  • Motor symptoms: tremor, brady- and hypokinesia
  • Non-motor symptoms: e.g. depression and fatigue
  • Gait: e.g. freezing of gait (FOG)
  • Balance problems: e.g. near falls, falls, fall-related self-efficacy, activity avoidance due to the risk of falling, dual task difficulties, and a clinical assessment of the postural response in relation to an external perturbation
  • Complications of therapy: e.g. experiencing fluctuations and/or dyskinesias
Since people with PD suffer from slowness and difficulties in performing daily transfers, two timed tests are included that tap mobility: walking and rising from a chair.
