What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new exoskeleton device designed to help people with Parkinson's disease walk better and reduce falls. The exoskeleton, a wearable device that supports the legs, aims to improve mobility and independence. Participants will wear the device under supervision twice a week for six weeks. The study seeks individuals with confirmed Parkinson's who experience balance or walking issues and have received a diagnosis from a specialist. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance mobility solutions for Parkinson's patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What prior data suggests that this exoskeleton is safe for people with Parkinson's disease?

Research has shown that exoskeletons, like the one being tested, are generally safe for people with Parkinson's disease (PD). Studies have found that a lightweight exoskeleton can aid in walking and balance. These devices assist movement without causing harm. In earlier studies, participants managed the exoskeleton well, with few reports of discomfort or side effects.

For instance, one study found that using an exoskeleton improved mobility without major negative effects. Participants experienced better support while walking. This suggests that the exoskeleton is a promising tool for enhancing mobility in people with PD. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for Parkinson's disease, which typically involve medications like levodopa to manage symptoms, the exoskeleton device offers a unique approach by directly enhancing mobility. The exoskeleton, Keeogo by B-Temia, Inc., is lightweight and designed to support and augment the user's movements, potentially improving their ability to walk and perform daily activities. Researchers are excited about this technology because it targets mobility issues directly, offering a non-pharmaceutical option that could complement existing treatments and provide a new level of independence for people with Parkinson's.

What evidence suggests that this exoskeleton is effective for improving mobility in Parkinson's disease?

Research has shown that using a robotic exoskeleton can help people with Parkinson's disease (PD) improve memory and walking ability. One study found that exercising with a simple exoskeleton improved both memory and walking endurance. This trial will assess the feasibility and safety of a lightweight ground exoskeleton (Keeogo, B-Temia, Inc.) to enhance mobility in people with PD. While traditional physical therapy provides only short-term benefits, the exoskeleton offers hope for longer-lasting improvements. These findings are promising but still under study for their full potential. ^{2 4 5 6 7}

Home-based gait training using the Stride Management Assist (SMA) exoskeleton significantly improved walking distance in people with moderately advanced Parkinson's disease, with participants in the SMA group walking an average of 13.7 meters further in a 3-minute test after training.

The SMA group also showed a significant reduction in the physiological cost index, indicating improved walking efficiency, while the control group did not experience any notable changes.
