Table 3 Range of motion (in degrees) employed during experiments

From: Voluntary control of wearable robotic exoskeletons by patients with paresis via neuromechanical modeling

Subject Knee angle (OUT-type) Ankle angle (OUT-type) Knee angle (IN-type) Ankle angle (IN-type)
Healthy −80 to −40 −10 to 10 −80 to −40 −10 to 10
Stroke 1 −80 to − 40 0 to 15 N/A N/A
Stroke 2 −80 to −40 −10 to 10 − 80 to − 40 −10 to 10
SCI −80 to − 40 − 10 to 10 −70 to −50 −10 to 10
  1. Ranges of motion were personalized for each recruited patient to avoid muscle overstretching and testing outside of safe boundaries. Knee flexion and ankle plantar-dorsiflexion are indicated by negative angles
