Exoskeletons in gait rehabilitation: progress and practical examples

Exoskeletons are robotic systems that support the human musculoskeletal system. They work with sensors, motors and control algorithms to simulate natural gait. Modern exoskeletons adapt to the user and enable targeted rehabilitation through various operating modes including passive, active and assistive support. They also collect real-time data on movement patterns, which improves the adaptation of therapy.

RoboCT's "Ugo" exoskeleton is aimed at adults with spinal cord injuries or after stroke, while "KGO" was developed specifically for children with muscular dystrophy or cerebral palsy. CEO Leo Q. Wang describes the company's mission: "We want to help more people achieve a better physical condition and improve their mobility."

A special feature of the RoboCT systems is the integration of AI and a real-time data platform. The exoskeleton analyzes the user's movement data and adapts the support accordingly. Wang explains: "The exoskeleton recognizes the effort required and provides targeted support to complete the step. Our platform also enables therapists to analyze the data in real time and adapt the treatment."

In addition, RoboCT offers various operating modes – from passive to active support – that enable flexible use in different rehabilitation phases. This technology opens new possibilities to continuously optimize training programs.

Exoskeletons bring about physiological and biochemical changes in the patient's body. Among other things, this affects oxygen saturation, muscle activity and neurological reorganization.

Patient reactions are also promising. "Many are skeptical or anxious at first. But as soon as they have taken their first steps with an exoskeleton, they often experience a boost in motivation," reports Bereziy. In some cases, stroke patients have been able to significantly improve their mobility after just a few weeks or even do without walking aids.

ExoAtlet and RoboCT see a bright future for exoskeletons in medical rehabilitation. According to Wang, exoskeletons have evolved over the last ten years from experimental laboratory devices to practical therapeutic aids: "In the past, they were only found in universities and research laboratories. Today they are used in clinics, and in future, they could even be available at home."

However, funding remains a key challenge. Bereziy criticizes the fact that health insurance companies in many countries are still reluctant to cover the costs: "In countries with health insurance systems, people are often less willing to invest in their own health." Nevertheless, there are initial programs in Germany, the USA and Japan that provide financial support for exoskeletons.
