Study of Powered Lower-Limb Exoskeleton Use to Improve Walking in Older Adults Aged 65 to 75 Comparison of Walking Performance With and Without the Device Including Healthy Young Adults Aged 18 to 22 for Reference

What this Trial Is About

Researchers are studying whether a powered wearable lower-limb exoskeleton can improve walking performance in independently walking older adults aged 65 to 75 years. The study aims to find out if the device increases comfortable walking speed over 10 meters and average walking speed during a 400-meter walk. The trial also compares walking in older adults with and without the exoskeleton and includes a young adult reference group to provide baseline walking performance data. Participants will be divided into two groups older adults who will complete walking tests with and without the powered exoskeleton in a randomized crossover design, and young adults who will complete walking tests without the device. Older adults will attend a screening and familiarization visit where they will be fitted with the exoskeleton and practice using it. They will then complete two trial visits with assessments of walking performance, physical tests, and questionnaires on balance confidence, fear of falling, and device usability. During the study, participants will perform walking tests including a 10-meter walk and a 400-meter walk, along with other physical performance assessments. Researchers will monitor heart rate, perceived exertion, and safety throughout testing. Questionnaires will assess balance confidence and satisfaction with the device. The study will measure walking speed and physical function to evaluate how the exoskeleton affects mobility. Participation involves screening, familiarization, and two trial visits, with safety monitoring conducted during all assessments.
