Table 2 Resulting mean gait kinematics of each walking bout

From: Biomechanics and energetics of walking in powered ankle exoskeletons using myoelectric control versus mechanically intrinsic control

Walking condition Step length Step width Step period Double support period
  (Normalized) (Normalized) (ms) (ms)
Unpowered 0.713 ± 0.010 0.173 ± 0.011 586.3 ± 5.6 161.7 ± 5.0
Timing-Based 0.704 ± 0.007 0.190 ± 0.016 591.6 ± 6.9 167.2 ± 2.8
Proportional Myoelectric 0.692 ± 0.008 0.182 ± 0.014 586.5 ± 6.6 169.0 ± 2.2
P-Value 0.004 0.030 0.095 0.256
  1. All values are reported as mean ±s.e.m. across subjects. All distance measurements have been normalized by leg length. P <0.05 represents a statistically significant difference between the proportional myoelectric controller and the timing-based controller
