ArmMotus™ EMU – next-gen rehabtech for patients

How the world-leading device is helping to redefine traditional neuro-rehab



Through the launch of the robot hailed as having the potential to change neuro-rehab as we know it, Fourier Intelligence is stepping up options for patients in their recovery further still. NR Times learns more about its pioneering ArmMotus™ EMU device

“It makes rehab fun – you don’t realise how much work you’re doing”

Through the use of the ArmMotus™ EMU, neuro-rehab is being redefined for people around the world who are living with brain injury, spinal cord injury and neurological conditions, with its revolutionary approach to recovery helping to change lives. 

The ArmMotus™  EMU – the world’s first 3D back-drivable upper limb rehabilitation robot – is designed to support upper limb rehabilitation, and through its ability to engage patients in games,  created especially to advance their recovery potential, it can chart their progress like never before. 

In a unique approach to rehab robotics, the ArmMotus™  EMU – created by global rehabtech leader Fourier Intelligence – used a games-based approach, combined with artificial intelligence, to precisely measure every movement trajectory, strength, cognitive ability, ROM and motor control ability, and then generate a report after each training period. 

This gives unparalleled insight for the therapist into the progress and current ability of the patient, enabling them to deliver more bespoke rehabilitation and a more personalised approach. 

Unveiled last year, the ArmMotus™  EMU has become a highly significant introduction into the rehab robotics market, with the device being hailed as helping to redefine the future. The upper limb device has also since won many awards – the iF Award, the Red Dot Design Award, the Medical Design Excellence Awards and the most recent, the Good Design Award.

“Current neuro-rehabilitation models primarily rely on extended hospital stays or regular therapy sessions which require close physical interactions between rehab professionals and patients,” said Zen Koh, Founder and global chief executive officer of Fourier Intelligence. 

“The COVID-19 pandemic situation has challenged this model and as a result, many neurological patients are not receiving sufficient therapy. There is an urgent need to rethink conventional neuro-rehabilitation therapy.

“The new ArmMotus™  EMU provides that solution. Equipped with clinical intelligence, it provides personalised therapy, technology-based solutions, coaching capabilities and remote monitoring.

“The implementation of fun functional games with embedded artificial intelligence also provides clinically motivating therapy to patients as well as giving caregivers and healthcare practitioners confidence.”

Users of the ArmMotus™  EMU speak of its ease of use and the joy of using its gamified approach – which uses a range of games including table tennis, cooking, and fishing, to simulate activities of daily living – and is a hugely different approach to the traditional rehab many people have experienced in the past. 

One patient, who is recovering from a spinal cord injury, said: “I really like that it helps me get my arms away from my body and I get a lot of exercise with it. 

“It makes it fun in a way because you’re playing games and you don’t realise how much work you’re doing. 

“But then afterwards you definitely feel like you’ve been doing something, you feel you’ve been working your arms. It’s been very useful for me; it has helped a lot.”

The ArmMotus™  EMU, jointly built by Fourier Intelligence and the University of Melbourne Robotics Laboratory, took six years to bring to fruition and was led by Professor Denny Oetomo.

The robot is the product of a hugely successful collaboration, one of many Fourier Intelligence is creating around the world with key sites in neuro-rehab and academia, to help pioneer the future of intelligent solutions which have the power to improve patients’ lives. 

Bringing together the huge tech capability of Fourier Intelligence’s team with the academic excellence of Professor Oetomo and his team, the launch of the ArmMotus™  EMU has been welcomed around the world. 

Covering the whole continuum of rehabilitation, it makes use of Fourier Intelligence’s sector-leading force feedback technology, which recreates the touch of a therapist’s hand and supports the user to adjust the assistance or resistance according to their needs. 

It also supports easy training setup in sitting and standing positions, as well as accommodating different training arms. The device integrates different scenarios in the game so that users can train on strength, motor control and joint ROM in one training session, making the whole rehabilitation process more efficient.

Through its ability to deliver real-time analysis and personalised feedback and reporting, a therapist can tailor a targeted therapy according to the patient’s training outcomes and needs, maximising the potential of each session. 

Its levels of engagement through games-based rehabilitation is also helping to drive patient outcomes through better levels of participation and effort.
