The search for effective treatment options to restore mobility and independence as quickly as possible after a stroke is of crucial importance. Robot-assisted physiotherapy and occupational therapy, also known as robotic neurotherapy (RNT), has attracted considerable interest in recent years. This innovative method uses state-of-the-art robotic therapy equipment to provide intensive and targeted rehabilitation for stroke patients.
RNT has some significant advantages in terms of the basic mechanisms of neurorehabilitation and neuroplasticity that are well established experimentally and clinically:
High intensity, repetition rate and task specificity as well as multisensory input:
From a neuroscientific point of view but also supported by clinical studies, it is currently assumed that the main trigger for neuroplasticity after brain / spinal cord injury is an early, intensive, high-frequency afferent input of the damaged neuronal structure (multimodal bottom-up access). This can be achieved very specifically with robotic aids.
Cardiorespiratory efficiency:
Since many patients have limited cardiorespiratory fitness, especially in the early phase of the disease, conventional therapy is often not possible or only possible to a limited extent or at a low frequency. Since the repetition rate is one of the key factors for the induction of neuroplasticity, robotic methods enable early multimodal bottom-up input despite limited cardiorespiratory reserves.
Patient participation:
Another limiting factor for sustainable early neurorehabilitation is often patient motivation. Compared to conventional methods, robotic forms of therapy have the advantage here that patient motivation can often be kept higher through performance feedback and the use of playful components (gamification), which leads to increased compliance, especially in the important early phase after neurological damage.
The treatment of patients after a stroke is one of the most promising applications of RNT. Several studies have also shown this. Due to the high intensity, specific movement patterns and multisensory input that RNT provides, stroke patients can achieve improved walking ability and functional independence.
It is particularly noteworthy that robot-assisted gait therapy (RAGT) for stroke patients offers a clear advantage over conventional physiotherapy.
In a recent Cochrane Review, the evidence was systematically summarized and a clear picture emerged for RAGT in stroke. Patients who received RAGT after a stroke had a significantly higher chance of being able to walk independently again than with conventional physiotherapy. In particular, patients who were unable to walk at the start of therapy benefited from RAGT. An early start (within the first 3 months after the stroke) also appears to be a positive predictive factor.
Furthermore, a Cochrane meta-analysis from 2018, which summarized 45 studies with a total of 1619 patients, showed that robot-assisted arm therapy can bring about a highly significant improvement in activities of daily living (ADLs), arm function and muscle strength. Patient adherence was very high for all different therapy devices and side effects were extremely rare.
Overall, the growing evidence shows that robot-assisted therapy is a promising option for the rehabilitation of stroke patients. With further research and development in this area, we could achieve even better results in the future and improve the quality of life of stroke survivors worldwide.
