Association Between Trapezius Muscle Stiffness and Headache Severity in Patients With Tension-Type Headache

Area of Science:

• Neurology
• Pain Management
• Musculoskeletal Research

Background:

• Tension-type headache (TTH) is a widespread neurological disorder with unclear causes.
• Myofascial factors, specifically trapezius muscle stiffness, are implicated in TTH severity.

Purpose of the Study:

• To investigate the association between upper trapezius muscle stiffness and headache severity in TTH patients.
• To identify clinical indicators correlating with TTH severity.

Main Methods:

• Cross-sectional study of 203 TTH patients.
• Muscle stiffness measured with a portable hardness meter.
• Headache severity assessed using HIT-6 and MIDAS scales.
• Logistic regression analysis adjusted for covariates.

Main Results:

• Upper trapezius muscle stiffness positively correlated with headache impact (HIT-6 scores).
• Chronic TTH and age were also associated with increased headache severity.
• Weakness and heavy eyelid sensation were significant clinical indicators of headache severity.
• Stress and weather changes identified as significant headache triggers.

Conclusions:

• Elevated trapezius muscle stiffness is a significant factor in TTH severity.
• Clinical signs like weakness and heavy eyelids may aid in diagnosing and managing TTH.
• Further research into myofascial factors could improve TTH treatment strategies.
