From: Frailty and physical function in chronic kidney disease: the CanFIT study

Test Scoring Total
Chair stand test The time taken for the participant to rise from sitting in a chair 5 times is measured. The test is completed without using hands on the chair or other tools to help the participant stand. 0 Unable or >60s 4 points
1 ≥16.70s
2 13.70–16.69 s
3 11.20–13.69 s
4 ≤11.19 s
Balance tests Side by Side: the participant is asked to stand with both feet side by side and the time is measured. 0 Unable or <10s 4 points
1 ≥10s
Semi-Tandem: the participant is asked to stand with one foot slightly more in front of the other and the time is measured. 0 Unable or <10s
1 ≥10s
Tandem: the participant is asked to stand with one foot in front of the other and the time is measured 0 Unable or <3 s
1 3.00–9.99 s
2 ≥10s
4 m gait speed test The time taken for the participant to walk 4 m is measured twice. The average time of the two trials is used to calculate score. Use of a mobility aid in the test was recorded. 0 Unable to Complete 4 points
1 >8.70s
2 6.21–8.70s
3 4.82–6.20s
4 <4.82 s
  1. The SPPB is scored from 0 to 4 in 3 sections for a maximum score of 12 and minimum score of 0. Scores were grouped by normal physical function and frail: score ≥10 (normal physical function) and score <10 (reduced physical function as measure of frailty)
