Film Mom standing up from a chair for 30 seconds.

See how her strength and balance compare with the CDC's averages for her age. Re-check every month and watch the trend.

The same three screening tests clinicians use (CDC STEADI): a 30-second chair stand, a 4-stage balance test and Timed Up and Go. Your phone's camera can count for you (beta), or you count by hand.

Safety first

Tick every box to continue. These tests involve standing up and balancing.

A helper (a second adult) will stand close by the whole time. A sturdy chair without arms (about 17 in / 43 cm seat), pushed against a wall so it can't slide. Clear space: about 3 m (10 ft) of open floor, no rugs, cords or pets in the way. Normal shoes. We'll stop at once if there's dizziness, pain, shortness of breath or unsteadiness. No doctor or therapist has said to avoid tests like these. I understand this is a general wellness check, not a medical diagnosis and not medical advice.

The one-foot balance stage is optional. Only try it with the helper right beside the person.

How should we count?

Use the camera

Prop the phone 2–3 m (7–10 ft) away at hip height, from the side, so the chair and the whole body are in view. Good light and fitted clothes help.

OK to download the pose-tracking files (up to about 20 MB, once; use Wi-Fi) from public CDNs. Video stays on this phone. The model's maker, Google, receives performance and usage metrics from it, not video. Details

Say the countdown and the count out loud

Count by hand

No camera. Tap a button for each stand and use the on-screen stopwatch.

Test 1 · 30-second chair stand

Sit in the middle of the chair, feet flat, arms crossed over the chest. On "Go", stand all the way up and sit all the way down, as many times as possible in 30 seconds.

30.0 s

When time ran out, were they more than halfway up?

Did they push up with their arms or hands?

The CDC form scores 0 if the arms are used.

Final number of stands

Test 2 · 4-stage balance

Hold each position for 10 seconds without moving the feet or holding on. Arms can move to help balance. No cane or walker, and keep the eyes open. The helper stands close. Stop at the first one that can't be held.

Stages held for 10 seconds, in a row

Test 3 · Timed Up and Go

Put a mark 3 m (10 ft) from the chair: tape, a shoe, or 4 big floor tiles. On "Go", stand up, walk to the mark at a normal pace, turn, walk back and sit down. Normal walking aid is fine.

The mark is placed 3 m (10 ft) away.

0.0

seconds

Final time in seconds

Stopped. That's fine.

Help the person sit down and rest.

If there was a fall, a hit to the head, chest pain or trouble breathing, get medical help now (in the US, call 911). If there was dizziness or unsteadiness, mention it to a doctor.

What this means

Below average on any test? The CDC says that indicates a higher risk of falls. Share this page with a doctor or physical therapist. Strength and balance exercise lowers the rate of falls in older people.

This is a general wellness check. It is not a medical diagnosis.
