What researchers measure

Primary outcomes

  1. Headache days change from baseline for cervicogenic headache

    Days with cervicogenic headache in the last four weeks from a daily headache diary. Change score = follow-up score - baseline score)

    Time frame: 0, 6, 12, 24, 39, 52 weeks

Secondary outcomes

  1. Average pain change from baseline for cervicogenic headache

    Average cervicogenic headache pain in the last four weeks evaluated by averaging daily headache diary pain scores. Pain is rated on a 0 to 11 numeric rating scale.

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  2. Headache-related disability change from baseline for cervicogenic headaches

    Headache Impact Test (HIT-6)

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  3. Headache-related disability days change from baseline

    Number of days in the last four weeks from recall unable to carry out daily work for at least one half day because of cervicogenic headache.

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  4. EuroQol-5D change from baseline

    Health-related quality of life

    Time frame: 0, 12, 24, 39, 52 weeks

  5. Average pain change from baseline for neck

    Average neck pain in the last four weeks from recall. Pain is rated on a 0 to 11 numeric rating scale.

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  6. Neck pain days change from baseline

    Number of days with neck pain in last 4 weeks from recall.

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  7. medication use change from baseline

    Number days of use of prescription and nonprescription medications for headaches with neck pain

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  8. Outside Care change from baseline

    Visits to providers outside the study for care of cervicogenic headache. Includes hospital and emergency room visits

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  9. Patient Satisfaction

    Likert scale for success of care

    Time frame: week 12

  10. Objective biomechanical measures change from baseline

    Measures of cervical joint function and kinematics including global range of motion, spinal segmental joint restriction, pain pressure thresholds

    Time frame: 0, 6 weeks

  11. Quality-adjusted life years change from baseline

    utility for cost-effectiveness analysis

    Time frame: 0, 12, 24, 39, 52 weeks

  12. Direct & Indirect costs change from baseline

    Health services; lost work days and productivity

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  13. Perceived headache average pain change from baseline for cervicogenic headache

    Perceived change in average pain from baseline on a -10 to +10 (21-point) numeric rating scale

    Time frame: 0, 6, 12, 24, 39, 52 weeks

  14. Perceived headache improvement from baseline for cervicogenic headache

    Perceived cervicogenic headache improvement from baseline on a 9-point Likert-like scale.

    Time frame: 0, 6, 12, 24, 39, 52 weeks
