Post-Traumatic Neck Pain

Post-traumatic neck pain is a common consequence of traffic-related and other accidental injuries. While many individuals recover, a subgroup develops persistent pain, disability, and psychological distress. Building on previous adaptation and feasibility work, this randomised pilot trial will assess the feasibility of conducting a future definitive randomised controlled trial comparing StressModex plus treatment as usual (TAU) with TAU alone in individuals at risk of persistent post-traumatic neck pain. The primary feasibility objectives are to assess recruitment using a revised multi-source recruitment strategy and participant retention and remote outcome data collection. Secondary feasibility objectives are to assess the feasibility and acceptability of randomisation, characterise TAU and concurrent healthcare use, and estimate parameters relevant to the sample size calculation for a future definitive RCT. Intervention fidelity, adherence, acceptability, safety, and practical aspects of intervention delivery will additionally be monitored. The pilot trial is not designed or powered to evaluate the effectiveness of StressModex.
