Is SPPB useful as a method for screening functional capacity in patients with advanced chronic kidney disease?

Abstract

Introduction and objectiveOne of the consequences of the CKD, is the deterioration of the functional capacity, being able to manifest from different stages of the disease, until renal replacement therapy.The objective of this study was to determine the functionality of patients with CKD through functional capacity test, valuing the usefulness of the SPPB as a screening test in parallel. Materials and methodsIt assessed the functional capacity of patients with CKD, using the test SPPB, 6MM, TUTG and STS. Also found the muscle strength with manual dynamometry. ResultsOf 121 patients who came to the CKD query, 118 presented a minimum functionality to perform tests of functional capacity, a 71.2% of the patients were able to perform 4 tests, a 28.8% only could make the SPPB test.To a 71.43% of patients who presented a low score in SPPB, not could follow assessed them with the rest of the test, while the 92.31% of which had a high score, continued with the rest of the evidence. To differentiate by age ranges, the majority of young patients have minimal limitations, finding higher rates of disability in older age ranges. A good score in SPPB meant to present good functional capacity and allowed to continue evaluating the patient, obtaining better results with the rest of test and more muscle strength. A good nutritional better status and body composition was a better functionality. ConclusionIn the absence of a consensus of what is the best method of determining the functional capacity of the kidney patient, and to assess all patients, propose to use the test SPPB as screening method, and depending on the result used as the rest of the test to more complete if it is necessary to study.
