30-second chair stand test · Sit-to-stand test

Purpose

Use this test to measure leg strength and endurance in older adults. Your client stands up from a chair and sits down again as many times as they can in 30 seconds.

The CDC uses it in STEADI, its fall prevention toolkit. Jones, Rikli and Beam found it a reliable and valid measure of lower body strength in active older adults living in the community.

Procedure

Preparation
Use a chair with a straight back, no arm rests and a seat about 43 cm (17 in) high. Stand next to your client for safety.
Equipment
Chair without arm rests and a stopwatch
  1. Sit in the middle

    Your client sits in the middle of the chair with the feet flat on the floor and the back straight.

  2. Cross the arms

    They cross the arms at the wrists, place the hands on the opposite shoulders and keep the arms against the chest.

  3. Stand and sit

    Say “Go” and start the stopwatch. Your client rises to a full stand, sits back down and repeats for 30 seconds.

  4. Count the stands

    Count each full stand. If your client is more than halfway up when the 30 seconds end, count it as a stand.

Stop the test if your client has to use their arms to stand, and record 0.

Scoring

The score is the number of full stands in 30 seconds.

Interpretation

The CDC lists the scores below as below average for each age. The calculator shows the count without a label.
