Providing early and effective treatment is a healthcare priority; however, current guideline-based care which focuses on education and physiotherapy-led exercise does not routinely address the psychosocial effects of trauma, and access to early integrated treatment is limited. This study aims to evaluate the feasibility of delivering and evaluating recovery, information, support and empowerment (RISE), a co-designed short message service-based intervention integrating psychosocial and exercise\/activity support for individuals with acute whiplash injury who are at risk of poor recovery in a randomised feasibility trial. Secondary aims are to explore preliminary changes in candidate clinical outcomes and opportunities for intervention personalisation and future implementation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>\n                      This mixed-methods randomised controlled feasibility trial with a nested process evaluation will recruit 50 participants (\n                      <jats:underline>&gt;<\/jats:underline>\n                      18 years) with WAD grade II\/III who are identified at medium to high risk of poor recovery and within 12 weeks of RTI from Queensland emergency departments and the community. Participants will be randomised in a 1:1 ratio to receive either the RISE intervention (tailored, daily messaging+optional brief clinician support session\/s) or an active control (general health-related text messages plus access to an online resource, My Whiplash Navigator). Feasibility outcomes, including recruitment and retention rates, data collection (including wearable-derived and economic data) and intervention uptake will be descriptively summarised and evaluated against pre-defined traffic light progression criteria. Acceptability will be examined using validated questionnaires and purpose-built items, qualitative interviews with intervention participants and focus groups with patients, clinicians and funders. Secondary aims will be addressed through preliminary estimates of between-group differences in patient-reported outcomes with 95% CIs and exploratory analysis of multimodal data (eg, wearable-derived physiological data, intervention engagement metrics) using a large language model where possible to inform future personalisation and implementation planning.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This trial is approved by the Townsville Hospital Human Research Ethics Committee (HREC\/QTHS\/121395) and ratified by the Human Research Ethics Committee at The University of Queensland, which is the study sponsor (2025\/HE002491).
