Fig 6 LOA plots for (A) peak torque, (B) angle of peak torque, (C) start ROM, and (D) end ROM. Circles represent the measured difference between the 2 devices for the 3 profiles. The solid line represents the mean difference between the 2 devices; the dashed lines represent the lower and upper LOA.
