Virtual Arm Boot Camp (V-ABC): study protocol for a mixed-methods study to increase upper limb recovery after stroke...

Area of Science:

• Neurorehabilitation
• Wearable Technology
• Behavioral Science

Background:

• Optimizing upper limb recovery post-stroke requires increased use and practice intensity.
• Wearable sensors offer feedback to influence practice behavior for better outcomes.
• Virtual rehabilitation programs enhance convenience and accessibility, especially during restricted in-person care.

Purpose of the Study:

• To determine the efficacy of a virtual behavior change program using wearable sensor feedback to increase upper limb use and function post-stroke.
• To explore patient experiences and perceptions of using wearable sensors within a home-based rehabilitation program.

Main Methods:

• A mixed-methods approach combining a prospective controlled trial with a nested qualitative study.
• Sixty-four adults within one year post-stroke were randomized to immediate or delayed intervention.
• The Virtual Arm Boot Camp (V-ABC) intervention included a wearable sensor (TENZR) for grasp counts and virtual therapist sessions.

Main Results:

• Primary outcome: increased upper limb use measured by grasp counts from the wearable sensor post-intervention.
• Secondary outcomes: improvements in upper limb function (Arm Capacity and Movement Test) and self-reported function (Stroke Impact Scale).
• Qualitative data explored participant experiences and acceptability of the wearable sensor-based home program.

Conclusions:

• The study provides novel insights into the efficacy of virtually delivered programs for upper extremity recovery.
• Wearable sensors can effectively assist in behavior change for stroke rehabilitation.
• The findings support the acceptability and potential of technology-enhanced home-based rehabilitation programs.
