Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Recruitment rate

    Recruitment rate will be assessed as the number of participants randomised per month during the active recruitment period. Recruitment will be evaluated against prespecified progression criteria: ≥5 participants per month (go), 3 to \<5 participants per month (amend), and \<3 participants per month (stop/reconsider).

    Throughout the active recruitment period, up to 10 months

  • Participant retention at 6-month follow-up

    Retention will be assessed as the proportion of randomised participants retained at the 6-month follow-up. Retention will be evaluated against prespecified progression criteria: ≥75% retention (go), 50 to \<75% retention (amend), and \<50% retention (stop/reconsider).

    6 months after randomisation

Secondary Outcomes (10)

  • Participant retention at 6-week and 3-month follow-up

    6 weeks and 3 months after randomisation

  • Completeness of remotely collected outcome data

    Baseline, 6 weeks, 3 months, and 6 months

  • Acceptance of randomisation

    At enrolment, prior to randomisation

  • Withdrawal following treatment allocation

    From randomisation to 6-month follow-up

  • Treatment as usual and concurrent healthcare use

    Baseline, 6 weeks, 3 months, and 6 months

  • +5 more secondary outcomes

Other Outcomes (21)

  • Pain intensity

    Baseline, 6 weeks, 3 months, and 6 months

  • Post-traumatic stress symptoms

    Baseline, 6 weeks, 3 months, and 6 months

  • Hyperarousal symptoms

    Baseline, 6 weeks, 3 months, and 6 months

  • +18 more other outcomes

Study Arms (2)

StressModex plus Treatment as Usual

EXPERIMENTAL

Participants allocated to this arm will receive StressModex in addition to treatment as usual (TAU). StressModex comprises 10 physiotherapy sessions delivered over six weeks and combines individually tailored, guideline-based physiotherapy with Stress Inoculation Training (SIT). SIT is integrated into six of the 10 sessions. Participants remain free to seek additional healthcare according to usual Danish practice throughout the study period.

Behavioral: StressModex plus Treatment as Usual

Treatment as Usual

NO INTERVENTION

Participants allocated to this arm will not receive the StressModex intervention. They will continue with treatment as usual and remain free to seek healthcare according to usual Danish practice, including consultation with their general practitioner and treatment from other healthcare providers as considered necessary.

Interventions

StressModex is a physiotherapist-delivered intervention combining guideline-based exercise therapy with stress inoculation training. Participants receive 10 treatment sessions over six weeks. Exercise components target neck mobility, strength, endurance, and sensorimotor function. Stress inoculation training components are integrated into six sessions and focus on stress education, relaxation strategies, coping skills, and self-management of stress-related symptoms following trauma.

StressModex plus Treatment as Usual

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 years
  • Post-traumatic neck pain with symptom duration of less than 6 months
  • Moderate neck-related disability, defined as Neck Disability Index (NDI) score ≥32%
  • Hyperarousal symptoms defined as a score of ≥3 on the hyperarousal subscale of the Posttraumatic Diagnostic Scale (PDS)
  • Able to read, understand, and communicate in Danish

You may not qualify if:

  • Known or suspected spinal pathology, including confirmed fracture or vertebral displacement related to the injury
  • Severe pre-existing pain condition judged to interfere with participation in the intervention, such as disc herniation, fractures, or recent major surgery
  • Known severe psychiatric disorder, including schizophrenia spectrum disorder or bipolar disorder, if the condition is currently considered unstable, insufficiently treated, or likely to affect the participant's ability to provide informed consent or participate meaningfully in the study
  • Known active misuse of alcohol, illicit drugs, anxiolytic medication, or opioids
  • Progressive neurological or rheumatological disorder causing substantial functional limitations and expected to interfere with participation in the intervention or assessment of treatment effect
  • Severe traumatic brain injury
