Similarly, in a sample of subjects with unilateral lumbar pain with or without ipsilateral leg symptoms, using a pendulometer (which is similar to the inclinometer) as the measuring tool, Boland and Adams determined mean ROM of SLR on the symptomatic side to be approximately 55°, although they used "onset of any pain in the leg or back, or stretch, pains, and needles, or numbness in the leg or back" as the end point. Boland and Adams did not measure ROM on the asymptomatic side, although Gabbe et al, in a sample of asymptomatic subjects, using an inclinometer, found mean ROM of SLR to fall between
65° and 70
