A robotic exoskeleton is an external mechanical structure that can be worn by a person, designed to assist, improve, or amplify the user’s movement and strength capabilities. These devices are typically constructed with rigid and resistant materials such as metal or high-strength plastics, and are powered by a system of motors, actuators, and/or hydraulic or pneumatic systems that provide additional force to body movements.
Robotic Exoskeletons Can Have Several Purposes:
Medical Rehabilitation: They are used in neurorehabilitation to help people who have suffered strokes, spinal cord injuries, or have conditions that affect mobility and strength. They can help in the recovery of motor functions and in muscle training.
Mobility Assistance: They provide support to individuals with disabilities to improve their daily mobility. For example, they can allow a person with a disability in their legs to walk again or improve stability and endurance when walking.
Improvement of Capabilities: They are used in industrial and military applications to improve the strength and endurance of users, allowing them to lift heavy loads or perform repetitive tasks with less fatigue.
Virtual Reality and Entertainment: In some contexts, exoskeletons can provide a more immersive experience in games or simulations, replicating physical sensations or resistance in the virtual environment.
Potential in Neurorehabilitation: Scientific Evidence
Several studies have demonstrated the benefits of exoskeletons in neurorehabilitation. For example, a 2020 article published in the «Journal of NeuroEngineering and Rehabilitation» highlights how training with exoskeletons significantly improves gait and mobility in patients with spinal cord injuries, compared to conventional therapies.
In addition, research in «The Lancet Neurology» in 2018 highlighted that exoskeletons, when used in post-stroke rehabilitation, not only promote early motor recovery, but also improve neuronal plasticity, essential for the recovery of motor functions.
Improvement of Autonomy and Quality of Life: Relevant Studies
The journal «Scientific Reports» published a study in 2019 where exoskeletons enabled individuals with paraplegia to perform daily tasks, improving their autonomy and mental health. This finding is crucial, as it underscores the impact of exoskeletons beyond physical rehabilitation, also affecting psychological well-being.
Precise Data for Personalized Treatments: the Digital Revolution in Neurorehabilitation
Advances in the collection of biometric data through exoskeletons allow for more personalized treatments. A 2021 study in «Frontiers in Robotics and AI» described how the telemetry incorporated in exoskeletons can inform therapists about muscle and joint performance in real time, thus optimizing rehabilitation regimens.
The Future of Exoskeletons: Integration and Accessibility
The integration of artificial intelligence (AI) in exoskeletons is a growing trend. An article in «IEEE Transactions on Neural Systems and Rehabilitation Engineering» projected that AI will allow exoskeletons to learn and adapt to each patient’s progress, making them more efficient. In addition, advances towards commercialization and cost reduction, according to a 2022 report in «Nature Reviews Neurology», will make exoskeletons more accessible to a wider population in the near future. Currently, the price of exoskeletons is only within the reach of a few or specialized neurorehabilitation clinics.
