Summary

The goal of this clinical trial is to learn whether a powered wearable lower-limb exoskeleton can improve walking performance in independently ambulatory older adults aged 65 to 75 years.

The main questions it aims to answer are:

* Does use of a powered lower-limb exoskeleton increase comfortable walking speed over 10 meters?
* Does use of a powered lower-limb exoskeleton increase average walking speed during a 400-meter walk?

Researchers will compare walking performance in older adults during walking with the powered exoskeleton and walking without the device to determine whether the exoskeleton improves mobility. Young-adult reference participants will also complete walking assessments to provide reference values for walking performance.

Participants will:

* Attend a screening and familiarization visit.
* Complete walking assessments with and without the powered exoskeleton in randomized order (older adults only).
* Perform a 10-meter walk test, a 400-meter walk test, and other physical performance assessments.
* Complete questionnaires about balance confidence, fear of falling, and device usability.
* Be monitored for safety events during testing.

Interventions

DEVICE

Powered Lower-Limb Exoskeleton

A commercially available powered wearable lower-limb exoskeleton (VIATRIX; ULS Robotics Co., Ltd., Shanghai, China) designed to provide bilateral lower-limb assistance during walking. The device is worn around the pelvis and lower limbs and provides powered assistance through bilateral actuation. During powered-device assessments, participants use the adaptive assistive walking mode following device fitting and familiarization procedures.
