11 November 2005
STATISTICAL COMMISSION and
UN ECONOMIC COMMISSION FOR
EUROPE
STATISTICAL OFFICE OF THE
EUROPEAN COMMUNITIES
(EUROSTAT)
CONFERENCE OF EUROPEAN
STATISTICIANS
WORLD HEALTH
ORGANIZATION (WHO)
Joint UNECE/WHO/Eurostat Meeting
on the Measurement of Health Status
(Budapest, Hungary, 14-16 November 2005)
Session 3 – Invited paper
Physical function: Mobility
National Center for Health Statistics, U.S.A
Physical Functioning: Mobility
 Concept:




Questions on this aspect of functioning are found on most health surveys
Getting from one place to another using lower limbs
Generally measured by walking and climbing steps; less often by running
Related lower body functions – bending, stooping, crouching
 Specification of tasks:
 Distance
 Speed
 Surface (e.g. level vs. incline; type of material; barriers)






Musculoskeletal conditions, missing limbs
Vision
Heart, Circulatory or Respiratory conditions
Neurological conditions relating to balance
Pain
Fatigue
Proposed items for measuring
physical function – mobility:
 By yourself, and without using any special
equipment, how much difficulty do you have…
…Walking a few steps?
…Walking a quarter of a mile/about 3 city blocks/xxx
meters?
…Walking up 10 steps with resting?
…Running a short way (about xxx meters)?
 NO DIFFICULTY
 ONLY A LITTLE DIFFICULTY
 SOME DIFFICULTY
 A LOT OF DIFFICULTY
 CAN’T DO AT ALL
Mobility: Characteristics of
Proposed Questions
 Filter Question:
 Not used: concern that use would eliminate less severe difficulties
 Assistive Devices:
 Optimum to obtain information on the use of devices and level of
difficulty with and without any devices used
 If not possible, obtain level of functioning without the use of devices
 Recall period/chronicity:
 Not specified
 Response categories
 No difficulty to can’t do at all
 Severity
 Measured for each activity
 Activities also vary in difficulty so a more complex hierarchy could be
obtained
