Walk test
Walking test (walking-speed) is the method most frequently used in clinical practice for measuring step velocity and represents the screening test for the diagnosis of sarcopenia. The space required to perform the test is a 5-7 meter corridor. The subject is invited to walk with a normal pace and the evaluator detects the time taken to walk 4 or 6 meters. A speed of less than 0.8 meters per second is considered abnormal.
