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.

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. |

|
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. |
