Effects of walking training with and without a robot and standard care on clinical and mobility outcomes: A randomized clinical trial in acute ischemic stroke patients
Publication Name: Experimental Gerontology
Publication Date: 2025-10-15
Volume: 210
Issue: Unknown
Page Range: Unknown
Description:
Background: Stroke incidence rises with age. A stroke can severely affect walking ability, requiring therapy. Robot-assisted walking therapy (ROB) has been advocated as one form of walking rehabilitation in stroke patients. However, its comparative efficacy remains controversial and three-group comparisons are scant. We compared the effects of ROB, walking training therapy without a robot (WTT) and standard treatment therapy (STT) on clinical and mobility outcomes in acute ischemic stroke patients. Methods: Individuals (n = 45, 71 % males, age 64.4y ±6.34), who have recently experienced an ischemic stroke, were randomized to ROB, WTT or STT. Clinical and mobility outcomes were assessed before and after each intervention (3 weeks, 5 sessions/week) and after 5 weeks of no-intervention follow-up. Results: Outcomes did not differ between groups at baseline (p > 0.05). Modified Rankin Scale (primary outcome), improved (p < 0.05) after ROB and WTT vs. STT. These improvements were retained relative to baseline (p < 0.05) after follow-up. Barthel index, Berg Balance Scale, 10-m walking speed, the distance while walking with and without the robot for six minutes, and center pressure velocity in standing improved most after ROB (all p < 0.001), exceeding the changes after WTT which in turn were greater than the changes after STT (p ≤ 0.040). Conclusion: Older adults shortly after an ischemic stroke can quickly learn to walk with a soft robot and retain substantial clinical and mobility improvements at follow-up.

Comparison of Five Rehabilitation Interventions for Acute Ischemic Stroke: A Randomized Trial
Publication Name: Journal of Clinical Medicine
Publication Date: 2025-03-01
Volume: 14
Issue: 5
Page Range: Unknown
Description:
Background: Comparative efficacy of rehabilitation interventions in persons with acute ischemic stroke (PwS) is limited. This randomized trial assessed the immediate and lasting effects of five interventions on clinical and mobility outcomes in 75 PwS. Methods: Five days after stroke, 75 PwS were randomized into five groups: physical therapy (CON, standard care, once daily); walking with a soft robotic exoskeleton (ROB, once daily); agility exergaming once (EXE1, once daily) or twice daily (EXE2, twice daily); and combined EXE1+ROB in two daily sessions. Interventions were performed 5 days per week for 3 weeks. Outcomes were assessed at baseline, post-intervention, and after 5 weeks of detraining. Results: Modified Rankin Scale (primary outcome) and Barthel Index showed no changes. EXE1, EXE2, ROB, and EXE1+ROB outperformed standard care (CON) in five secondary outcomes (Berg balance scale, 10m walking speed, 6-min walk test with/without robot, standing balance), with effects sustained after 5 weeks. Dose effects (EXE1 vs. EXE2) were minimal, while EXE1+ROB showed additive effects in 6-min walk tests. Conclusions: These novel comparative data expand evidence-based options for therapists to design individualized rehabilitation plans for PwS. Further confirmation is needed.

Investigation of the Effectiveness of the Robotic ReStore Soft Exoskeleton in the Development of Early Mobilization, Walking, and Coordination of Stroke Patients: A Randomized Clinical Trial
Publication Name: Robotics
Publication Date: 2024-03-01
Volume: 13
Issue: 3
Page Range: Unknown
Description:
Medical robotics nowadays can prevent, treat, or alleviate numerous severe conditions, including the dire consequences of stroke. Our objective was to determine the effect of employing a robotic soft exoskeleton in therapy on the development of the early mobilization, gait, and coordination in stroke patients. The ReStore™ Soft Exo-Suit, a wearable exosuit developed by a leading company with exoskeleton technology, was utilized. It is a powered, lightweight device intended for use in stroke rehabilitation for people with lower limb disability. We performed a randomized clinical intervention, using a before–after trial design in a university hospital setting. A total of 48 patients with a history of stroke were included, of whom 39 were randomized and 30 completed the study. Interventions: Barthel Index and modified Rankin scale (mRS) patients were randomly assigned to a non-physical intervention control (n = 9 of 39 completed, 30 withdrew before baseline testing), or to a high-intensity agility program (15 sessions, 5 weeks, n = 30 completed). The main focus of assessment was on the Modified Rankin Scale. Additionally, we evaluated secondary factors including daily life functionality, five dimensions of health-related quality of life, the Beck depression inventory, the 6 min walk test (6MWT), the Berg Balance Scale (BBS), and static balance (center of pressure). The Robot-Assisted Gait Therapy (ROB/RAGT) program led to significant improvements across various measures, including a 37% improvement in Barthel Index scores, a 56% increase in 10 m walking speed, and a 68% improvement in 6 min walking distance, as well as notable enhancements in balance and stability. Additionally, the intervention group demonstrated significant gains in all these aspects compared to the control group. In conclusion, the use of robotic therapy can be beneficial in stroke rehabilitation. These devices support the restoration and improvement of movement in various ways and contribute to restoring balance and stability.

Telerehabilitation After Brain Injuries: Its Efficacy and Role in Reducing Healthcare Burdens
Publication Name: Acta Polytechnica Hungarica
Publication Date: 2023-01-01
Volume: 20
Issue: 8
Page Range: 305-320
Description:
Rehabilitation following brain injuries, such as stroke and other traumatic injuries, presents significant challenges for both patients and healthcare systems. Traditional in-person rehabilitation often requires regular visits to specialized facilities, which can be difficult for patients in remote areas or those with mobility and financial constraints. Telerehabilitation offers a promising solution by enabling patients to continue essential therapy at home, ensuring continuity of care while reducing the burden on healthcare providers. It can be effectively applied across various patient groups, including children, adults, the elderly, amputees, individuals with traumatic neurological injuries, and those with neurocognitive impairments such as dementia. Our telemedicine platform integrates advanced technologies, i.e., 3D motion analysis and Virtual Reality (VR) to enhance home-based physiotherapy. These tools enable precise monitoring, real-time feedback, and immersive therapy sessions, in order to improve coordination, fine motor skills, hand-eye coordination, and the vestibular system, which is crucial for balance. This platform also performs detailed offline data analysis, allowing healthcare professionals to adjust therapy plans based on individual needs. As the demand for rehabilitation services continues to grow, adopting these technologies will be crucial for sustainable, effective healthcare, ultimately improving patient outcomes and shaping a more efficient and equitable future for healthcare systems.

Publication Name: Acta Polytechnica Hungarica
Publication Date: 2023-01-01
Volume: 20
Issue: 8
Page Range: 321-336
Description:
The application of virtual reality (VR) technology in both upper and lower limb rehabilitation represents a significant advancement in the field of medicine. VR-based therapies provide patients with the opportunity to engage in intensive, repetitive, and targeted exercises that promote neuroplasticity and improve the motor skills necessary for daily life. VR has long been recommended for the rehabilitation of conditions such as in case of ischemic stroke, Parkinson’s disease, and multiple sclerosis, further underscoring its versatility and therapeutic potential. In our study, we evaluated the effectiveness of VR therapy focusing on stroke rehabilitation. The reviewed VR systems provided motion analysis, tracking, feedback reinforcement, and realistic environments to facilitate the restoration of motor functions. Furthermore, we developed a VR-based therapy aimed at both upper and lower limb motor functions, combined with traditional rehabilitation. The application of VR technology not only promotes the improvement of motor functions but also offers economic advantages by reducing the burden on healthcare workers and increasing rehabilitation capacity. Further research is needed to determine the optimal conditions for applying VR therapy in clinical practice.

Design, programming and orchestration of heterogeneous manufacturing systems through VR-powered remote collaboration
Publication Name: Robotics and Computer Integrated Manufacturing
Publication Date: 2015-01-01
Volume: 33
Issue: Unknown
Page Range: 68-77
Description:
Modern manufacturing systems are often composed of a variety of highly customized units and specifically designed manufacturing cells. Optimization of assembly and training of staff requires a series of demo installations and excessive use of costly operational resources. In some cases, components are located at different sites, making the orchestration of the whole system even more difficult. Virtual Reality (VR) collaboration environments offer a solution by enabling high fidelity testing and training of complex manufacturing systems. On the other hand, such platforms are difficult to implement in an engineering perspective, as they are required to provide reliable, standard interfaces towards both robotic components and human operators. The VirCA (Virtual Collaboration Arena) platform is a software framework that supports various means of collaboration through the use of 3D augmented/virtual reality as a communication medium. VirCA offers functions for the high-level interoperability of heterogeneous components in a wide range of domains, spanning from research & development, through remote education to orchestration and management of industrial processes in manufacturing applications. This paper provides an overview of the industrial requirements behind high-fidelity virtual collaboration and demonstrates how the VirCA platform meets these requirements. Use cases are provided to illustrate the usability of the platform.
