Study on Using a Wearable Robotic Exoskeleton to Improve Walking and Balance in Older Adults and People with Parkinsons Disease

What this Trial Is About

Researchers are studying whether a wearable robotic exoskeleton can improve mobility, balance, and walking in healthy older adults and people living with Parkinsons disease. These groups face a high risk of falls and mobility challenges due to age-related or disease-related movement impairments. The study aims to understand the immediate effects of the exoskeleton on walking and balance, identify who benefits most, and explore how users feel about using this technology in daily life. The study involves two laboratory sessions held 2 to 4 days apart. In the first session, participants undergo clinical assessments, are fitted with the exoskeleton, and take part in interviews about their expectations and perceptions. In the second session, they perform mobility tasks such as walking and standing with and without the exoskeleton under six different conditions, including various levels of assistance and no assistance. The order of assistance levels is randomized. Movement is measured using wearable sensors to gather detailed walking data. Participants will be involved in clinical tests of balance, gait, physical activity, mood, fatigue, and cognition, along with interviews before and after exoskeleton use. Mobility performance will be evaluated through timed walking and standing tests, and walking variability will be monitored using sensors. For those with Parkinsons, assessments occur during their optimal medication effect. The study measures immediate changes in walking speed, balance, and sit-to-stand times, as well as user acceptability of the device. Participation spans two sessions over about a week, with all data collected in a controlled lab setting.
