REX is a hands-free robotic mobility device for rehabilitation.

Designed for people with mobility impairments, REX is completely self-supporting and rapidly adjustable for each user, opening up the rehabilitative benefits to a wide range of people.

Rex Bionics is working with physiotherapists to develop the practice of Robot-Assisted Physiotherapy (RAP). In a session of RAP, REX lifts patients from a sitting position into a robot-supported standing position, allowing them to take part in a set of supported walking and stretching exercises, designed by specialist physiotherapists.

REX also limits the burden on the therapists during manual handling and reduces the amount of help required to assist patients who are undergoing standing therapy.

Wheelchair users are at risk of developing numerous medical complications from extended periods of sitting. By enabling them to spend more time standing, walking and exercising, REX may offer significant health benefits. A programme of clinical trials is now under way to evaluate these potential benefits.


“These robotic rehabilitation systems have the potential to offer individualized therapy, increased efficiency of training at a lower cost, and new sensing capabilities to the physical therapist to quantify patient’s progress.The availability of safe and reliable robotic therapy can also facilitate intense practice -at a reasonable cost- as well as continuous challenge during rehabilitation, which is known to accelerate recovery and improve rehabilitation outcomes. However, most exoskeleton devices are currently limited to patients with intact upper body function for aided support via crutches (a notable exception is Rex, which does not require crutches for balancing and stability). This is
 an important limitation in current exoskeleton systems as stroke patients and quadriplegics lack control on at least one side of their bodies and cannot use a walker or crutches to stabilize their body effectively”

“I use REX in my rehabilitation centres because it can take the user through a range of active assisted movements and can be used as part of a rehabilitation programme for patients with spinal cord injury and hemiplegia arising from stroke or a traumatic brain injury”
