This Special Issue aims to explore the crucial role of physical function tests as predictors of key health outcomes in various clinical populations. The topic is at the intersection of clinical research and patient care, addressing the need for effective assessments that can enhance our understanding of health trajectories. As physical function assessments play a vital role in patient management, this Special Issue seeks to showcase their applications, relevance, and potential solutions to existing healthcare challenges.

The current landscape of research on physical function tests faces challenges related to standardization, comprehensive applicability, and the need for validated tools in diverse clinical conditions. More research is required to address the variability in testing protocols and establish robust correlations between physical function outcomes and broader health parameters. Researchers are actively working to develop more precise methodologies and explore interdisciplinary collaborations to overcome these challenges.

The primary objective of this Special Issue is to gather a comprehensive collection of studies that highlight the predictive power of physical function tests in clinical populations. We welcome original research articles and review articles that contribute to understanding how physical function assessments can inform healthcare decisions and improve patient outcomes. Submissions that address the standardization of testing procedures, identify novel predictors, and explore the integration of technological advances in this field are particularly encouraged.
