30-Second Chair Stand

Purpose

Counts full chair rises completed within a 30-second interval.

Equipment

Approximately 17-inch armless chair, stopwatch

Protocol

CDC STEADI: sit mid-chair, feet flat and arms crossed; repeatedly stand fully and sit for 30 seconds. Count a stand if more than halfway up at 30 seconds.

Interpretation

Higher repetition count generally reflects more chair-rise capacity. CDC age/sex comparison requires appropriately selected demographics; this build omits normative automation.

Safety

Stop if the patient must use arms under CDC scoring rules and record zero; guard against falls.
