September 30, 2026 updated by: Wake Forest University Health Sciences

Wearable Robotics to Overcome Exercise Dose Limitations in Older Adults

The purpose of this research is to learn whether a lightweight wearable robotic device called We Innovate Mobility (WIM) can improve exercise capacity and physical function for older adults.

Detailed Description

Study 2 is an open-label, randomized, parallel-group controlled pilot trial. Participants will be randomized in a 1:1 ratio to eight weeks of supervised We Innovate Mobility (WIM)-assisted treadmill walking or conventional treadmill walking. Exercise intensity will be prescribed using a target of 70% heart rate reserve, with speed and grade adjusted to maintain walking intensity. Outcomes will be assessed before and after the intervention.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: We Innovate Mobility (WIM)-Assisted Treadmill Walking

participants will walk on treadmill with assistance from the We Innovate Mobility (WIM) device

We Innovate Mobility (WIM) is an externally worn, powered device that provides temporary mechanical assistance during voluntary walking. Participants will walk on the treadmill three times per week for eight weeks while wearing the device.

Active Comparator: Conventional Treadmill Walking

participants will walk on treadmill without assistance from the We Innovate Mobility (WIM) device

Participants will walk on the treadmill three times per week for eight weeks without assistance from the We Innovate Mobility (WIM) device.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Peak Oxygen Consumption
Time Frame: From baseline to week 8

Change in peak oxygen consumption (VO2peak)

From baseline to week 8

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Exercise Dose
Time Frame: Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7, Week 8

Exercise dose is defined was walking duration x average treadmill speed x average treadmill grade

Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7, Week 8
400 Meter Walk Time
Time Frame: Baseline and Week 8

Participants will be instructed to walk 400 meters at their usual fast pace without running, with standardized encouragement provided throughout the test. Participants will be permitted to slow down or rest briefly if needed for safety. Total completion time recorded. Participants will be permitted to slow down or rest briefly if needed for safety.

Baseline and Week 8
Expanded Short Physical Performance Battery (eSPPB)
Time Frame: Baseline and Week 8

eSPPB consists of 5 repeated chair stands, standing balance (semi- and full-tandem stands and a single leg stand for 30 seconds), a 6-meter walk to assess usual gait speed, and a narrow 6-meter walk test of balance (walking at usual pace within lines of tape spaced 20 cm apart). Total score range is 0-4 with a higher score indicating better performance.

Baseline and Week 8
PROMIS Fatigue Short Form 7a Survey
Time Frame: Baseline and Week 8

PROMIS Fatigue Short Form 7a measures the severity and functional impact of fatigue on everyday functioning. Total score range is 7-35 with a higher score indicating a higher level of fatigue.

Baseline and Week 8
Pittsburgh Fatigability Scale
Time Frame: Baseline and Week 8

Activity-related fatigability will be assessed using the Pittsburgh Fatigability Scale which evaluates perceived physical fatigue in response to standardized daily activities of defined intensity and duration. Total score range is 0-50 with higher numbers representing greater perceived fatigability.

Baseline and Week 8

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oxygen Consumption Rate
Time Frame: Baseline and Week 8

Oxygen consumption rate of the peripheral blood mononuclear cells (PBMC) cells measured using respirometry.
