From: Review of control strategies for lower-limb exoskeletons to assist gait

Inclusion criteria

Exclusion criteria

\(\bullet\) Includes description of controller(s) applicable to lower-limb exoskeletons with the purpose of helping wearer’s gait, or detection methods applicable to such controllers

\(\bullet\) Describes a controller that is specific to other devices such as prosthetics, upper-limb exoskeletons, fixed-frame rehabilitation devices (such as Lokomat [326] and MotionMaker [327]) or portable devices that operate as external units rather than wearable robots (e.g. WalkTrainer [328]) or devices that were designed only for animals

\(\bullet\) Date of publication: January 2000 to August 2020

\(\bullet\) Describes a controller for devices that assist locomotion by using another movement than the natural movement of the human leg (such as rolling devices, jumping stilts in which the blade moves below the foot, jet-packs [329] and portable inertial devices [330, 331])

\(\bullet\) Language of publication: English

\(\bullet\) Describes a controller that is intended for assisting load-carrying or strength augmentation without significantly affecting the gait itself

\(\bullet\) Type of publication: peer-reviewed journal or conference article, patent

\(\bullet\) Describes a controller that is impossible to apply outside of a simulated environment

 

\(\bullet\) Does not give enough details about the control method to fully describe it (typically the case for papers reporting clinical trial outcomes)

 

\(\bullet\) Gives inconsistent information about the controller and/or the device

 

\(\bullet\) Only reviews control methods
