Muscle trigger point therapy in tension-type headache

Area of Science:

• Neurology
• Pain Medicine
• Physical Therapy

Background:

• Active trigger points (TrPs) in neck and shoulder muscles are increasingly implicated in the pathophysiology of tension-type headache (TTH).
• Specific muscles, including suboccipital, upper trapezius, sternocleidomastoid, temporalis, superior oblique, and lateral rectus, harbor TrPs associated with both chronic and episodic TTH.
• Referred pain from these active TrPs in posterior cervical, head, and shoulder muscles may provoke the characteristic pain profile of TTH, potentially increasing central sensitization.

Purpose of the Study:

• To review the role of active trigger points in the development and presentation of tension-type headache.
• To discuss various therapeutic approaches for managing trigger points, focusing on their inactivation.
• To highlight the preliminary evidence suggesting trigger point inactivation as a potential treatment strategy for TTH.

Main Methods:

• Literature review of recent evidence linking active trigger points to tension-type headache.
• Discussion of therapeutic modalities aimed at trigger point inactivation.
• Analysis of preliminary findings on the efficacy of trigger point inactivation in TTH management.

Main Results:

• Active trigger points in specific neck and shoulder muscles are associated with tension-type headache.
• The presence of active TrPs correlates with heightened sensitization in TTH patients.
• Preliminary data suggest that inactivating trigger points may be an effective treatment for a subset of TTH patients.

Conclusions:

• Active trigger points in the neck and shoulder musculature are a significant factor in tension-type headache.
• Trigger point inactivation presents a promising therapeutic avenue for managing TTH, particularly in responsive individuals.
• Further research is essential to fully elucidate the relationship between muscle trigger point inactivation and tension-type headache outcomes.
