Feasibility and reliability of physical fitness tests in older adults with intellectual disability: a pilot study

J Intellect Dev Disabil. 2012 Jun;37(2):158-62. doi: 10.3109/13668250.2012.681773. Epub 2012 May 1.


Background: Physical fitness is relevant for wellbeing and health, but knowledge on the feasibility and reliability of instruments to measure physical fitness for older adults with intellectual disability is lacking.

Methods: Feasibility and test-retest reliability of a physical fitness test battery (Box and Block Test, Response Time Test, walking speed, grip strength, 30-s chair stand, 10-m Incremental Shuttle Walking Test and the Extended Modified Back-Saver Sit-and-Reach Test) were investigated in older adults with ID in a convenience sample of 36 older adults (mean 65.9, range 50-89 years), with differing levels of intellectual disability and mobility.

Results and conclusion: All tests to measure physical fitness in older adults with ID had moderate to excellent feasibility and had sufficient test-retest reliability (ICCs .63-.96). No statistically significant learning effects were found.
