Horn, PT DScPT, MHS,NCS, Karen H. Lambert PT, MPT, NCS and the Vestibular EDGE task force of the Neurology Section of the APTA.
Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

40-62% of participants had unsuccessful trials at least once during testing, Participants found the test more difficult to perform than the Step Test. However, FSST was preferred by participants because they felt it was relevant to daily life and examined challenging skills (Blennerhassett and Jayalath, 2008).
The Four Square Step Test may be helpful in identifying individuals (older adults > 65 y/o) with vestibular disorders who have difficulty changing directions (Whitney 2007).

NOTE. Predictive value positive reflects the probability that scoring above the cutoff correctly identified multiple fallers, and predictive value negative reflects the probability that the non- multiple fallers were correctly identified as scoring at or below the cutoff (Dite & Temple, 2002).
