Physical Profile of Cervicogenic Headache: Comparison With Neck Pain and Healthy Controls

20. srpna 2026 aktualizováno: fatih bali, Istanbul Medipol University Hospital

A Multidimensional Physical Profile of Cervicogenic Headache: A Cross-Sectional Comparison With Nonspecific Neck Pain and Healthy Controls

The goal of this observational study is to compare physical findings across three adult groups. Cervicogenic headache (CGH) is a headache linked to a problem in the neck. Neck pain may affect posture, muscle function, grip strength, and sensitivity to pressure. Researchers do not know whether CGH has a distinct pattern of these findings.

The main questions are:

Do posture, grip strength, muscle stiffness, elasticity, and pressure sensitivity differ among the groups?
Are any differences more closely associated with CGH than with neck pain?

Researchers will compare adults ages 25 through 60. One group will include people with CGH lasting at least three months. Another group will include people with neck pain lasting at least six months. People in the neck pain group will have no headaches. Healthy participants will have no neck pain or headaches.

Researchers will not provide treatment or change participants' usual care. Each participant will complete one study visit lasting about 15 minutes. Participants will:

Answer short questions about their health and pain
Stand while researchers measure their head and neck posture
Squeeze a device that measures grip strength
Complete brief tests of neck muscle stiffness and elasticity
Tell researchers when applied pressure first becomes painful

Researchers will compare results across the three groups. The findings may guide future CGH assessment and treatment research.

Studijní populace

The study population consists of adults aged 25-60 years recruited at the study site in Istanbul, Türkiye. Participants are classified into three groups according to predefined clinical criteria. The cervicogenic headache group includes individuals diagnosed by a physician according to the International Classification of Headache Disorders, 3rd edition. The chronic nonspecific neck pain group includes individuals with neck pain lasting at least 6 months and no headache. The healthy control group includes individuals without neck pain or headache. Participants receive no study intervention and complete one questionnaire-based and instrument-based assessment session.

Co je měření studie?

Primární výstupní opatření

Měření výsledku	Popis opatření	Časové okno
Bilateral Upper Trapezius Muscle Stiffness Časové okno: During the single assessment session at enrollment	Upper trapezius muscle stiffness will be assessed bilaterally using the MyotonPRO device. Three consecutive measurements will be obtained at the midpoint between the C7 spinous process and the lateral border of the acromion. The mean of the three measurements will be used. Stiffness will be expressed in newtons per meter (N/m), with higher values indicating greater stiffness.	During the single assessment session at enrollment
Bilateral Upper Trapezius Logarithmic Decrement Časové okno: During the single assessment session at enrollment	Upper trapezius logarithmic decrement will be assessed bilaterally using the MyotonPRO device at the same standardized measurement site. Three consecutive measurements will be obtained on each side, and their mean will be used. Logarithmic decrement is a dimensionless inverse indicator of tissue elasticity, with lower values indicating greater elasticity.	During the single assessment session at enrollment

Sekundární výstupní opatření

Měření výsledku	Popis opatření	Časové okno
Bilateral Handgrip Strength Časové okno: During the single assessment session at enrollment	Bilateral handgrip strength will be measured using a Jamar Hydraulic Hand Dynamometer set to the second handle position. Participants will perform three maximal contractions with each hand in a standardized seated position. The highest value for each hand will be recorded in kilograms, with higher values indicating greater handgrip strength.	During the single assessment session at enrollment
Bilateral Upper Trapezius Pressure Pain Threshold Časové okno: During the single assessment session at enrollment	Pressure pain threshold will be measured bilaterally over the upper trapezius using a handheld pressure algometer with a 1-cm² probe. The measurement site will be the midpoint between the C7 spinous process and the lateral border of the acromion. Pressure will gradually increase until the participant first reports pain. Values will be recorded in kg/cm², with higher values indicating a higher pressure pain threshold.	During the single assessment session at enrollment
Bilateral Suboccipital Pressure Pain Threshold Časové okno: During the single assessment session at enrollment	Pressure pain threshold will be measured bilaterally over the suboccipital region using a handheld pressure algometer with a 1-cm² probe. The measurement site will be located 2 cm lateral to the C2 spinous process. Pressure will gradually increase until the participant first reports pain. Values will be recorded in kg/cm², with higher values indicating a higher pressure pain threshold.	During the single assessment session at enrollment
Tragus-to-Wall Distance Časové okno: During the single assessment session at enrollment	Tragus-to-wall distance will be measured in millimeters using a tape measure. Participants will stand with their heels, sacrum, and thoracic spine resting comfortably against a wall while maintaining a natural head position. The distance between the wall and the tragus will be recorded. Greater distances indicate greater forward positioning of the head.	During the single assessment session at enrollment
Craniovertebral Angle Časové okno: During the single assessment session at enrollment	The craniovertebral angle will be measured in degrees using a universal goniometer. The fulcrum will be positioned over the lateral projection of the C7 spinous process. The stationary arm will remain parallel to the floor, and the movable arm will point toward the tragus. Three measurements will be obtained, and their mean will be used. Smaller angles indicate greater forward head posture.	During the single assessment session at enrollment
