Validity and Utility of a Modified Short Physical Performance Battery Assessment and Scoring Approach in Middle-Aged and Older Adults

Despite the widespread usage of the Short Physical Performance Battery (SPPB), psychometric limitations in the SPPB have impeded its use for outcome monitoring and clinical decision making. We propose an alternative assessment and scoring approach for the SPPB, and we compared the modified and the original SPPB on their discriminative and clinical value concerning the risk of prefrailty/frailty, probable sarcopenia, and restricted life-space mobility (RLSM).
