When designing the ExoMotus™ M4 lower-limb exoskeleton robot, the primary goal was to create a device that simplified gait training for both therapists and patients. Eliminating the need for complicated setup and control procedures required by other exoskeletons. Operating using a simple tablet enables therapists to focus on providing quality patient care rather than wasting valuable time on device setup.

To ensure the device is accessible to more patients, a body-weight support frame and built-in chair were incorporated. Unlike other exoskeletons that require patients to have upper body strength and use crutches or be held up using a hoist system, the device has a vertical degree of freedom that allows users to practice ambulation with a natural gait pattern. With an ergonomic balance frame and multiple harnesses for added safety, patients can confidently engage in therapy without fear of falling.

With an average setup time of just five minutes, the ExoMotus™ M4 empowers therapists and patients to focus on the rehabilitation process. In addition, the device also features an open platform system, EXOPS™ (Exoskeleton & Robotics Open Platform System, http://exops.fftai.com/), which allows suppliers to plug directly into the Fourier ecosystem and provide better solutions to customers.

The ExoMotus™ M4 comprises of various high-strength materials such as steel, aluminium, fabric, and plastic. This ensures the comfort and safety of the patients while also giving portability to the device, with a total weight of 100 kilograms for the support frame and a mere 40 kilograms for the exoskeleton. Supported by 4 low-friction wheels to maximise user convenience, the outer width of the balancing support frame meets the entry requirements of conventional 1,000kg elevators and hospital entrances. In addition, it also incorporates a built-in seat that allows patients who use wheelchairs to mount and dismount from the device.

Currently, the ExoMotus™ M4 can be seen in countries such as the UK, Shanghai, Singapore & Philippines, where it is used in hospitals and rehabilitation centres.

According to a report by Grand View Research, the robotic rehabilitation market is projected to reach USD 671.8 million by 2025, with a compound annual growth rate (CAGR) of 15.4%. WHO has also estimated that over 1 billion people are affected by disabilities that impact their mobility and independence. Considering the numbers provided, there is huge potential for rehabilitation robotics and technology.

In view of this, patients who have utilised the ExoMotus™ M4 during their rehabilitation sessions have given positive feedback, emphasising the device's ability to stimulate their muscles and make them feel more connected with their bodies. Its design allows patients to move more freely during therapy sessions, reducing stress and creating a more enjoyable rehabilitation experience.

In addition, the ExoMotus™ M4’s versatility allows it to aid various patients and not be limited to only neurological patients. The device allows therapists to customise gait parameters based on the patient's stage of recovery, allowing for high-repetition training, which is crucial for motor skill relearning. This personalised approach enhances patient outcomes by providing targeted therapy tailored to each individual.
