About this study

Official title: Factors Affecting Treatment Response in Patients With Medication-Overuse Headache Undergoing Greater Occipital Nerve Blockade

The aim of this study to evaluate pre-injection patient-related factors that may influence treatment response in patients with medication-overuse headache who underwent ultrasound-guided greater occipital nerve block.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Treatment outcomeOther

    Before the injection, patients will be evaluated for the number of headache days, headache severity, the number of days of analgesic use for headache, headache-related disability, pressure pain threshold over the bilateral greater occipital nerve, anxiety and depression scores, and sleep quality. At 1 and 2 months after the injection, they will be reassessed for the number of headache days, headache severity, and the number of days of analgesic use for headache. In addition, at 1 hour after the injection, the pain experienced during the injection procedure will be assessed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the number of days of analgesic use for headache

    Patients will be questioned the total number of days on which they used analgesics for headache during the past month.

    Measured: Baseline

Secondary outcomes (6)
  1. Headache severity

    Patients will be questioned about headache severity using the Visual Analog Scale (VAS). A 10-cm-long horizontal straight line will be used for VAS assessment. 0 is considered no pain, and 10 is considered the most severe pain.

    Measured: Baseline

  2. Post-injection pain severity

    Patients will be questioned about post-injection pain severity using the Visual Analog Scale (VAS). A 10-cm-long horizontal straight line will be used for VAS assessment. 0 is considered no pain, and 10 is considered the most severe pain.

    Measured: Baseline

  3. Headache-related disability

    Patients will be questioned about headache-related disability using the Headache Impact Test-6 (HIT-6). The HIT-6 consists of six items, each scored on a 5-point Likert scale. The total score is calculated by summing the scores of all six items, with higher scores indicating a greater impact of headache on daily life.

    Measured: Baseline

  4. Pressure pain threshold

    The pressure pain threshold over the bilateral greater occipital nerve will be assessed using a manual pressure algometer (Baseline Dolorimeter®). Pressure pain threshold measurement will be performed over the medial one-third of an imaginary line drawn between the external occipital protuberance and the mastoid process. During the measurement, the 1.52 cm² flat circular probe of the algometer will be placed on the relevant area, and pressure will be increased at a rate of 1 kg per second. Patients will be asked to indicate the moment they first perceived pain. The value for the reference area will be calculated as the arithmetic mean of the right and left measurements.

    Measured: Baseline

  5. Anxiety and depression levels

    Patients' anxiety and depression symptoms will be assessed using the Hospital Anxiety and Depression Scale (HADS). The HADS is a 14-item scale consisting of two subscales: anxiety and depression. For each subscale, the minimum score is 0 and the maximum score is 21. Higher scores indicate greater severity of anxiety and depression symptoms.

    Measured: Baseline

  6. Sleep quality

    Patients will be evaluated in terms of sleep quality using a 4-point Likert-type scale. They wii be asked to describe their sleep quality by selecting one of the following options: "good," "mildly impaired," "moderately impaired," or "severely impaired."

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Medication-overuse Headache and Treatment, run by Sultan 1. Murat State Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the number of days of analgesic use for headache (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2026.
