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).
