The purpose of this research study is to learn whether a lightweight wearable robotic device called We Innovate Mobility (WIM) can improve exercise capacity and physical function for older adults.
Community-dwelling adult aged ≥65 years
Able to safely wear and use the WIM device
Willing to complete conventional and WIM-assisted treadmill walking
Able to provide informed consent and comply with study procedures
Recent hospitalization, surgery, fracture, or other medical condition that limits safe treadmill walking
Resting blood pressure, heart rate, or symptoms that meet protocol-defined safety exclusion criteria before exercise
Willing to complete conventional and WIM-assisted treadmill walking
Requires a cane, walker, or other assistive device for ambulation

We Innovate Mobility (WIM) Device
DeviceWe Innovate Mobility (WIM) is an externally worn, powered device that provides temporary mechanical assistance during voluntary walking. Participants will walk on the treadmill while wearing the device.
Conventional Treadmill Walking
Other interventionParticipants will walk on the treadmill without assistance from the WIM device.
Exercise Dose
Exercise dose is defined as walking duration × average treadmill speed × average treadmill grade.
Rate of Perceived Exertion
Rate of Perceived Exertion scale is 6-20 with the higher the number indicating a higher level of exertion.
Number of Participants that Ended Walking Session
Number of participants that wanted to stop walking sessions due to symptoms such as shortness of breath, leg fatigue, dizziness, balance difficulties, pain, etc.
WIM Walking Experience Survey
We Innovate Mobility (WIM) Walking Experience survey has a total score range of 8-40 with higher score indicating a more comfortable experience with the device.
