A new two square agility test for workplace health-reliability, validity and minimal detectable change.

The study used a convenience sample and excluded people who were disabled from work, had severe pain, had recent falls from dizziness or loss of consciousness, could not rise from a chair without armrests, or could not walk 30 feet without an assistive device. The participants were healthier than the general working population, with a mean BMI of 27.9 and more than half reporting vigorous physical activity, so the results may not apply to older, more impaired, or less active workers. Only 78 of 248 participants returned for the second session, so the one-week reliability estimate rests on a smaller group. The study assessed reliability and correlations with other mobility tests, not whether the TSAT predicts injury, productivity, return to work, or clinical outcomes. The authors' claims about workplace value, inclusiveness, and practical advantages are interpretations from the Discussion, not measured results.

The study was partly funded by a grant from the Ohio Physical Therapy Association Research Committee. The funding agency had no role in the study design, writing the manuscript, or the decision to submit for publication. No manufacturer aid was received and no conflicts of interest were declared.

Do not conclude that the TSAT is a validated workplace screening test for all workers. The study tested only measurement properties in 248 relatively healthy adults who could perform sit-to-stand and walking tasks, and it did not show that the score predicts injury, productivity, or fitness.
