To reduce the need for a large number of executed physical function tests we examined inter‐relations and determined predictive power for daily physical activity of the following tests: 6‐min walk, 10 repetition sit‐to‐stand, time up‐and‐go, Storke balance, handgrip strength, upper limb tapping and sitting forward bend tests. In 90 dialysis and 140 healthy control subjects we found high correlations between all tests, especially those engaging lower extremities. Sit‐to‐stand, forward bend and handgrip strength were selected for the test battery and composite motor performance score. Sit‐to‐stand test was superior in terms of sensitivity to uremia effects and association with daily physical function in adjusted analyses. There was no incremental value in calculating the composite performance score. We propose to standardize the physical function assessment of dialysis patients for cross‐sectional and longitudinal observations with three simple, cheap, well‐accessible and easily performed test tools: sit‐to‐stand test, handgrip strength and Human Activity Profile questionnaire.
