8’ Walking Speed (WS) Equipment: Stopwatch, painter’s tapePreparation: Measure and mark a 12 foot walkway. Add a mark at 2 feet and at 10 feet (see diagram below).Overview: the subject walks without assistance 12 feet and the time is measured for the intermediate 8 feet to allow for acceleration and deceleration.Start timing when the toes of the leading foot cross the 2-foot mark.Stop timing when the toes of the leading foot cross the 10-foot mark.Assistive devices can be used but should be kept consistent and documented from test to test.If physical assistance is required to walk, this test should not be performed.Can be performed at self-selected WS or fastest speed possible; documentation should include the speed tested (preferred vs. fast).Self-selected WS indicative of current functional status (Verghese et all 2011). See Encompass Gait Speed calculator in Clinical TookitFastest WS indicative of capabilities in community (Salbach et al, 2013). 3.9 feet/second or greater required to ensure safe street crossing in USWhen possible, collect three trials and calculate the average time of the three trials in seconds (Lusardi, 2009).Actual velocity: Divide 8 by the single (or average) time to get feet/second.9994907747000409257542545 10 feet00 10 feet460275643677 12 feet00 12 feet155646842932 2 feet00 2 feet105553634981 0 feetfeetfeet00 0 feetfeetfeetPatient Instructions: Self-selected speed: “I will say ready, set, go. When I say go, walk at your normal comfortable speed until I say stop.”Fastest speed trials: “I will say ready, set, go. When I say go, walk as fast as you can safely until I say stop.”References:Bohannon, RW.
