short physical performance battery

The Short Physical Performance Battery (SPPB) is a quick, nifty test used mainly in geriatrics to assess lower extremity function. It combines three components: balance tests, gait speed over 4 metres, and chair stands. Scores range from 0 to 12, with higher scores indicating better physical performance. It's often used to predict disability, frailty, and even mortality risk. If you want to dive deep, official medical literature and geriatric assessment guidelines are your friends.
