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

[Purpose] One promising strategy for workplace wellness programs is to emphasize functional mobility screening and coaching to promote suitable physical activity and reduce musculoskeletal risks. This study examined intra-rater reliability, test-retest reliability, concurrent validity, known-groups validity and minimal detectable change for a new Two Square Agility Test (TSAT) designed as a functional mobility measure to promote workplace health. [Participants and Methods] Two hundred forty eight non-disabled participants (ages 18-69) were measured for body size, physical activity and 3 trials of the Two Square Agility Test.
