Table 4 Kinematics for therapist-controlled and patient-controlled orthoses by speed. Mean ± standard error and statistical results for kinematics of two subjects with incomplete spinal cord injury who walked wearing orthoses powered under pushbutton control by a therapist (TC) and wearing orthoses powered under pushbutton control by the patient him/herself (PC) for 0.36 m/s, 0.54 m/s, 0.72 m/s and 0.89 m/s.

From: The effects of powered ankle-foot orthoses on joint kinematics and muscle activation during walking in individuals with incomplete spinal cord injury

  1. Values are means ± SE. See METHODS for calculations.
  2. * Indicates a p-value of less than 0.05 showing significant differences between conditions. Statistical power, P, is reported under the p-value. Tukey Honestly Significant Difference, THSD, results are reported for metrics with significance.
  3. Two subjects completed all conditions at all speeds.
  4. Double support time is for a single subject. As a result no statistical tests could be carried out for this metric.
