PMID 35128743WHAT IT FOUND
Adults with intellectual disability could complete the Functional Movement Screen, and trained-assessor ratings stayed similar over two weeks, but total scores were low and did not identify sport-injury risk.
Key findings
0130 people with intellectual disability completed all assessments.
02Completion rates were 100% for the active straight-leg raise and shoulder mobility, 93.4% for the deep squat, 83.4% for the hurdle step, in-line lunge and trunk stability push-up, and 66.6% for the rotary stability.
03The trained assessor's test-retest ICC was 0.887, and the novice assessors' ICC values were 0.602 to 0.759.

What it does not show
Participants were recruited from one residential and day care centre, and those with wheelchair dependence, disturbing behaviours, morbid obesity or joint pain that would prevent the screen were excluded. 33 agreed to take part, but 30 completed all assessments; two declined the screen and one missed the retest. The screen was scored from video, not in real time, because the trained assessor had to guide participants and control fall risk, so reliability in normal clinic use is unknown. The study did not test whether the screen predicts injury; it only examined feasibility and reproducibility. Subgroups by ID severity were small, so results may not generalise.
The easy way to misread this
Do not use the Functional Movement Screen to decide whether an adult with intellectual disability is at risk of sport injury. The study checked feasibility and scoring agreement, not injury prediction, and the authors concluded the screen did not discriminate risk.
