The Short Physical Performance Battery is a discriminative tool for identifying patients with COPD at risk of disability

Abstract

BackgroundLimited mobility is a risk factor for developing chronic obstructive pulmonary disease (COPD)-related disabilities. Little is known about the validity of the Short Physical Performance Battery (SPPB) for identifying mobility limitations in patients with COPD.ObjectiveTo determine the clinical validity of the SPPB summary score and its three components (standing balance, 4-meter gait speed, and five-repetition sit-to-stand) for identifying mobility limitations in patients with COPD.MethodsThis cross-sectional study included 137 patients with COPD, recruited from a hospital in Spain. Muscle strength tests and SPPB were measured; then, patients were surveyed for self-reported mobility limitations. The validity of SPPB scores was analyzed by developing receiver operating characteristic curves to analyze the sensitivity and specificity for identifying patients with mobility limitations; by examining group differences in SPPB scores across categories of mobility activities; and by correlating SPPB scores to strength tests.ResultsOnly the SPPB summary score and the five-repetition sit-to-stand components showed good discriminative capabilities; both showed areas under the receiver operating characteristic curves greater than 0.7. Patients with limitations had significantly lower SPPB scores than patients without limitations in nine different mobility activities. SPPB scores were moderately correlated with the quadriceps test (r>0.40), and less correlated with the handgrip test (r<0.30), which reinforced convergent and divergent validities. A SPPB summary score cutoff of 10 provided the best accuracy for identifying mobility limitations.ConclusionThis study provided evidence for the validity of the SPPB summary score and the five-repetition sit-to-stand test for assessing mobility in patients with COPD. These tests also showed potential as a screening test for identifying patients with COPD that have mobility limitations.

Validation of a Multi–Sensor‐Based Kiosk for Short Physical Performance Battery

“…Since its development, numerous studies have shown discrimination ability of the SPPB in evaluating the functional status of older adults. For instance, studies have shown that worse physical performance based on the SPPB is associated in older adults with increased risk for the occurrence of functional impairment, cognitive deterioration, hospitalization, and all‐cause mortality . With these clinical perspectives, SPPB has been served as the main criterion for selecting study populations or a key outcome measure for efficacy in clinical research focusing on the physical performance of the older adults …”

“…In addition, we found that the SPPB summary score, a cutoff score of <10, provided the most accurate determination of the prolonged postoperative LOS. Moreover, this cutoff value may also be used to identify older persons with chronic obstructive pulmonary disease at high risk of functional impairment 24 and mobility limitations 25 . Also, SPPB scores <7 are generally associated with a higher fall rate in the elderly; an SPPB score <5 could identify patients at major risk of death after discharge from acute care hospitals.…”

“…The SPPB represents the sum of the results from three component tests of functional relevance: standing balance, 4MGS, and 5STS. 12 Research has shown that poor performance on SPPB is highly predictive of subsequent disability and mortality. 13 18 .…”
