Updated with references for the PD population by Jeffrey Hoder, PT, DPT, NCS and the PD EDGE task force of the Neurology Section of the APTA in 2013.
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.

With regards to use for people with PD: Average time of SLS for age 80 in healthy older adults is < 10 seconds (Springer, 2007). This may not be a valid predictor of falls in individuals over age 80. Follow up studies after Jacobs (Mak, 2009, 2010) failed to identify 10 seconds as an accurate cut-off to discriminate fallers from non-fallers.

Parkinson’s Disease
(Jacobs, 2006)
Cut-off time of 10 seconds provided the highest sensitivity and specificity for history of one or more falls (75% of those that had a h/o falls exhibited OLS time of 10 seconds or less (high sensitivity); 74% of non-fallers exhibited OLS time of > 10 seconds (high specificity). 67 subjects with PD with 65 age-matched controls (mean age of 67+ 12 years; PD 10+6 yrs)
For the one-leg stance test, a cut-off time of 10 seconds provided the best combination of sensitivity and specificity for fall history in the PD subjects, consistent with a previous report by Smithson et al who reported that PD subjects with a history of falling, on average, exhibited one-leg stance times of under 10 seconds, and PD subjects without a history of falling, on average, exhibited one-leg stance times of about 15 seconds.
