Chair-Rise Test (Sit-to-Stand)

Last updated Sat May 30 2026 00:00:00 GMT+0000 (Coordinated Universal Time)

ObservationalStandard SPPB component

Two common protocols

  • 5-time chair rise: time how long it takes to stand and sit 5 times, starting seated.
  • 30-second chair stand: count how many full rises completed in 30 seconds.

Both measure lower-body strength (especially knee extensors and hip extensors), balance, and dynamic stability. The 5-time version is a component of the Short Physical Performance Battery (SPPB).

Why it’s prognostic

  • Falls risk (the single most predictive feature of subsequent falls).
  • Mortality in older adults.
  • Post-surgical complication risk.
  • Independence in ADLs.

What improves it

  • Squats, leg press, lunges — loaded if possible.
  • Step-ups.
  • Tai chi for balance and confidence.
  • Treating osteoarthritis pain.
  • Treating peripheral neuropathy contributors.
