The Computer Assisted Rehabilitation Environment (CAREN) is the world’s most advanced biomechanics laboratory. Developed by Motek, the CAREN is a versatile, multi-sensory system used for clinical analysis, rehabilitation, and the evaluation and training of human movement, balance and gait.

The CAREN combines a motion platform with six degrees of freedom, an instrumented force plate dual belt treadmill, motion capture, high speed video, D-Flow software, virtual reality (VR) and surround sound, and uses game elements and immersive interactions to engage the subject within a real time feedback loop.

The CAREN can be used for countless types of research and clinical rehabilitation, ranging from neurological and musculoskeletal disorders, amputees, brain and spinal injuries, multiple sclerosis, Parkinson’s disease, military servicemen and women, and return-to-sport rehabilitation.

The system’s support harness means that patients can start training early and confidently, even wheelchair users, in a safe environment. Therapists can adjust the patient’s gait, monitor the immediate effects, and generate reports, all with just a few easy clicks.

The CAREN is used in the UK by leading institutions such as the Defence and National Rehabilitation Centre (DNRC) at Stanford Hall, the Brain and Spinal Injury Centre (BASIC), the University of Strathclyde, Loughborough University, and Liverpool John Moores University.

CAREN Configurations

There are two different configurations available, which can be tailored to your specific needs:

Box Icon CAREN Extended

CAREN Extended

This features a dual-belt instrumented treadmill which is mounted on the motion base. There is also a cylindrical virtual reality projection screen which allows wider peripheral vision scope of up to 180 degrees. This is bespoke for balance and all gait applications.

Box Icon CAREN High End

CAREN High End

This model is the most advanced set up, featuring a 360 degrees dome for a fully-immersive virtual reality experience and a dual belt mounted instrumented treadmill. Again, this is bespoke for all balance and gait applications.

Box Icon CAREN Upgrades

CAREN Upgrades

Every CAREN can be upgraded in terms of kinetic and kinematic add-ons, wireless EMG, motion capture, data gloves, head mounted systems, haptic systems, heart rate measurement systems, energy consumption systems, pressure measurement systems, and other device integrations using the D-Flow software.

The Defence and National Rehabilitation Centre

Summit Medical and Scientific installed Europe’s first CAREN High End at the Defence and National Rehabilitation Centre (DNRC) at Stanford Hall in 2018. It is currently being used in the rehabilitation and therapy of injured military veterans and active servicemen and women for a wide range of conditions, including brain and spinal injuries, neurological disorders and amputees.

The GRAIL (Gait Realtime Analysis Interactive Lab) is a complete solution for gait analysis on 25m², and training in challenging conditions on a dual-belt instrumented treadmill with fast pitch and sway.

Box Icon HapticMaster VR

HapticMaster VR

The HapticMaster VR is a haptic robot designed to give users a realistic sense of touch in a virtual or remote world using their upper extremities.

Box Icon M-Gait


The M-Gait is a modular 3D instrumented dual-belt treadmill, which can have various upgrades to enhance your set-up such as pitch and sway, motion capture, bodyweight support and virtual reality.

Box Icon N-Mill Treadmill

N-Mill Treadmill

Smaller than the C-Mill (now distributed by Hocoma), the N-Mill is a single belt treadmill with an optional force plate.

Box Icon Motek Software

Motek Software

Including D-Flow, a control software suite which provides real-time data streams and users can easily create their own applications, and The Human Body Model for visualisations of muscle forces of the subject’s body on-screen.



The RYSEN is the next generation of 3D body weight support systems, assisting patients in an all-directional, assist as-needed capacity to improve movement function.
