results of his peers of the same age and gender a score below average you can see in the picture here under indicates a risk for Falls the chair stand test has proven to be reliable in terms of test retest reliability with correlation coefficients ranging from 0.86 to 0.92 it has also been validated against the one repetition maximum leg press test test with correlation coefficients ranging from 0.71 to 0.78 previous evidence by write it all in 2011 found a change of at least two repetitions in the 32nd CTO St test a minimally clinically important difference the

construct validity was poor according to tolal in 2019 who studied the validity of the test in people with neoa however alkazar at all in 2020 found that c stand power obtained from the 32nd cus stand test appears to be a valid measure of bilateral lower limb power and was found to be more strongly connected to physical performance than maximal hand grip strength repetition based sit to stand performance derived from the chair stand test and leg extension power if you want to learn more about this and improve the assessment we refer you to our blog I
