Key result
The modified Six-Minute Walk Test demonstrated excellent test-retest reliability (ICC = 0.98) and significant concurrent validity with VO2 peak (R = 0.84, p < 0.001).

A modified Six-Minute Walk Test is a highly reliable and valid tool for assessing cardiovascular fitness in adults with intellectual disability.
Supports modified 6MWT as fitness proxy in intellectual disability; leaves open prospective outcome validation before routine use.
BACKGROUND: The Six-Minute Walk Test (6MWT) has been used with clinical and healthy populations to assess functional capacity and cardiovascular fitness. The aim of this study was to determine the test-retest reliability of a modified-6MWT as well as concurrent validity of walk distance with peak oxygen uptake (VO₂ peak). METHOD: Participants were 13 adults (males = 7) with intellectual disability aged 18-44 years recruited from Special Olympics, and with no medical contraindications to exercise. The 6MWT was modified to include familiarisation, a 1:1 pacer, and encouragement every 15 s. Each participant performed the graded maximal treadmill test and the modified-6MWT twice. RESULTS: Test-retest reliability of the modified-6MWT was ICC = .98, and linear regression revealed that the modified- 6MWT distance was significantly related to VO₂ peak (R = .84, p < .001). CONCLUSIONS: The modified-6MWT is easy to administer and score and shows acceptable validity and excellent reliability for assessing cardiovascular fitness in adults with intellectual disability.

Nasuti et al. (2012) conducted a cross-sectional in Intellectual disability (n=13). Modified Six-Minute Walk Test (modified-6MWT) vs. Graded maximal treadmill test (VO2 peak) was evaluated on Test-retest reliability and concurrent validity with VO2 peak (R = 0.84, p=< .001). The modified Six-Minute Walk Test demonstrated excellent test-retest reliability (ICC = 0.98) and significant concurrent validity with VO2 peak (R = 0.84, p < 0.001).
