About this trial
Stroke survivors often walk more slowly and may have difficulty producing the movements needed to walk efficiently. This study will evaluate whether vibrotactile feedback, delivered through small wearable devices that provide vibrations during walking, can help individuals with chronic stroke change specific walking movements related to walking speed, propulsion, and balance.
Participants will complete a single study visit at Bucknell University. During the visit, participants will perform several walking trials with and without vibrotactile feedback and will complete common clinical mobility and balance assessments. Motion capture technology and wearable sensors will be used to measure movement during walking.
The goal of this study is to better understand how vibrotactile feedback can be used to improve walking performance after stroke and to support the future development of rehabilitation approaches for stroke survivors.

Single group
Treatments tested in this trial
Vibrotactile Feedback System
DeviceParticipants will receive vibrotactile feedback using a wearable SageMotion system consisting of inertial measurement units mounted on elastic straps. The system calculates joint angles during walking and provides vibration-based feedback when predefined movement goals are achieved. Feedback conditions will target trailing limb angle, ankle plantarflexion, and trunk sway during walking.
Treatment groups
Trial outcomes
Primary outcomes
Walking Speed
Walking speed measured during walking trials using timing gates and compared between baseline and vibrotactile feedback conditions.
Secondary outcomes
Forward Propulsion
Maximum anterior ground reaction force measured during walking trials using force plate data and compared between baseline and vibrotactile feedback conditions.
Trailing Limb Angle
Trailing limb angle measured during walking trials using motion capture and wearable sensor data and compared between baseline and vibrotactile feedback conditions.
Ankle Plantarflexion Angle
Peak ankle plantarflexion angle measured during walking trials using motion capture and wearable sensor data and compared between baseline and vibrotactile feedback conditions.
Gait Symmetry
Symmetry ratio calculated between limbs for trailing limb angle, ankle plantarflexion angle, and forward propulsion during walking trials.
