Table 5 Glossary of terms concerning input control signals of robots for rehabilitation

From: A survey on robotic devices for upper limb rehabilitation

Term Description
Dynamic signals Signals related to the torque or force exerted by the subject on various joints of the device (exoskeleton-based device) or at its end effector (end-effector-based device).
Kinematic signals Signals related to positions, orientations, velocities and accelerations of particular segments or joints of the device or of the limb.
Trigger signal A signal initiating a specific action. In simple cases, a switch or a button triggers the signal. In more complex cases, a threshold value of some signal is specified to trigger the action (e.g. a sEMG value corresponding to a level of muscle contraction).
