Summary

This study tests whether an AI-powered chatbot can guide a personalized walking program for people with mild traumatic brain injury (mTBI). Participants follow a 12-week exercise plan with wearable fitness trackers, receiving real-time feedback and motivational messages via a mobile app. The goal is to see if this approach improves physical fitness, sleep quality, and mood compared to standard care. The trial also checks how usable and engaging the chatbot is for patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AI chatbot-assisted aerobic exercise program with personalized feedback
What this could lead to
If effective, this could offer a scalable, low-cost way to improve physical function, sleep, and mood in people recovering from mild traumatic brain injury.
What could go wrong
The trial is small (50 participants) and early-stage, so results may not apply broadly. The program depends on technology and user adherence, which could limit its real-world impact.

About 50 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Aug 2031

An estimate. End dates often move.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Eligible participants are patients aged over 18 with mild TBI (GCS 13-15) * who can walk independently, * reside in the Greater Taipei area, * and possess sufficient Chinese or Taiwanese language proficiency to understand the trial * complete self-administered questionnaires. Exclusion Criteria: include individuals with severe medical conditions (e.g., respiratory failure, epilepsy, psychiatric disorders), musculoskeletal or neurological impairments * hindering physical activity in the 6-minute walk test, * cognitive impairments (MMSE \< 24), * frontal lobe injuries or penetrating injury causing significant psychological dysfunction. * Patients regularly engaging in moderate-to-high-intensity aerobic exercise or participating in other studies will also be excluded to avoid bias.
