Study summary

The goal of this prospective case series is to assess the feasibility of intervention and assessment protocols for telehealth intervention with mindfulness-based exercise, transcranial direct current stimulation, and their combination in Veterans with peristent post-traumatic headache. The main questions it aims to answer are:

What percentage of patients complete pre- and post- assessment measures? Are patients adherent to and satisfied with each intervention? What are potential adverse effects of treatment? How responsive are patient-reported outcome measures and biomarkers of brain connectivity, muscle health, and pain sensitivity to change following treatment?

Participants will complete 18 telehealth sessions with a physical therapist (3x/wk for 6 weeks) with one of the following interventions:

  1. mindfulness-based cervicoscapular exercise
  2. transcranial direct current stimulation (tDCS) over the motor cortex
  3. combined treatment with exercise and tDCS

Participants will complete the following assessments before and after intervention:

  1. magnetic resonance imaging (MRI) of the brain
  2. MRI of neck muscles
  3. quantitative sensory testing of pain sensitivity
  4. health questionnaires
