Collaborative robotic biomechanical interactions and gait adjustments in young, non-impaired individuals.

Journal of neuroengineering and rehabilitation
BACKGROUND: Collaborative robots are used in rehabilitation and are designed to interact with the client so as to provide the ability to assist walking therapeutically. One such device is the KineAssist which was designed to interact, either in a sel...

A novel 4-DOF surgical instrument with modular joints and 6-Axis Force sensing capability.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: It is difficult for surgeons to exert appropriate forces during delicate operations due to lack of force feedback in robot-assisted minimally invasive surgery (RMIS). A 4-DOF surgical grasper with a modular wrist and 6-axis force sensing ...

A novel robot for imposing perturbations during overground walking: mechanism, control and normative stepping responses.

Journal of neuroengineering and rehabilitation
BACKGROUND: The most common approach to studying dynamic balance during walking is by applying perturbations. Previous studies that investigated dynamic balance responses predominantly focused on applying perturbations in frontal plane while walking ...

Impact on gait biomechanics of using an active variable impedance prosthetic knee.

Journal of neuroengineering and rehabilitation
BACKGROUND: An above knee amputation can have a significant impact on gait, with substantial deviations in inter-leg symmetry, step length, hip exertion and upper body involvement even when using a current clinical standard of care prosthesis. These ...

Evaluation of three force-position hybrid control methods for a robot-based biological joint-testing system.

Biomedical engineering online
BACKGROUND: Robot-based joint-testing systems (RJTS) can be used to perform unconstrained laxity tests, measuring the stiffness of a degree of freedom (DOF) of the joint at a fixed flexion angle while allowing the other DOFs unconstrained movement. P...

A cortically-inspired model for inverse kinematics computation of a humanoid finger with mechanically coupled joints.

Bioinspiration & biomimetics
The human hand's versatility allows for robust and flexible grasping. To obtain such efficiency, many robotic hands include human biomechanical features such as fingers having their two last joints mechanically coupled. Although such coupling enables...

Development of a compact continuum tubular robotic system for nasopharyngeal biopsy.

Medical & biological engineering & computing
Traditional posterior nasopharyngeal biopsy using a flexible nasal endoscope has the risks of abrasion and injury to the nasal mucosa and thus causing trauma to the patient. Recently, a new class of robots known as continuum tubular robots (CTRs) pro...

Biomechanical effects of body weight support with a novel robotic walker for over-ground gait rehabilitation.

Medical & biological engineering & computing
Body weight support (BWS) promotes better functional outcomes for neurologically challenged patients. Despite the established effectiveness of BWS in gait rehabilitation, the findings on biomechanical effects of BWS training still remain contradictor...

Robotics in Arthroplasty: A Comprehensive Review.

The Journal of arthroplasty
Robotic-assisted orthopedic surgery has been available clinically in some form for over 2 decades, claiming to improve total joint arthroplasty by enhancing the surgeon's ability to reproduce alignment and therefore better restore normal kinematics. ...

A biologically-inspired multi-joint soft exosuit that can reduce the energy cost of loaded walking.

Journal of neuroengineering and rehabilitation
BACKGROUND: Carrying load alters normal walking, imposes additional stress to the musculoskeletal system, and results in an increase in energy consumption and a consequent earlier onset of fatigue. This phenomenon is largely due to increased work req...
