Physical performance tests are useful for evaluating and monitoring the severity of locomotive syndrome

We confirmed the validity of GLFS-25 by demonstrating a significant correlation and association of its score with the outcome of a series of functional performance tests. One-leg standing time with eyes open, timed up-and-go test and grip strength proved to be easy, reliable and safe performance tests to evaluate and monitor an individual's severity of LS as a complement to the GLFS-25. We also proved that knee and low back pain significantly impact the degree of LS.
