NERVE BLOCKS AND TRIGGER POINT INJECTIONS IN THE TREATMENT OF CHRONIC HEADACHES

A new study "Patterns of use of peripheral nerve blocks and trigger point injections among headache practitioners in the USA: Results of the American Headache Society Interventional Procedure Survey (AHS-IPS)" in Headache found widespread use of trigger point injections and nerve blocks it headache treatment. Many Neuromuscular dentists have a great deal of expertise in the utilization of these injections as part of coordinated treatment for Migraines, Tension-Type headaches and TMJ disorders.

Neuromuscular Dentists recognize that these injections are effective but do not address the underlying causes of patients problems. Correction of the Neuromuscular relationships and trigeminal nerve innervated muscles function is the key to long term correction of these problems. When diagnostic blocks and trigger points are effective the next step is to utilize a diagnostic orthotic to reduce noxious input to the Trigeminal nervous system and correct underlying postural pathology.

Abstract
BACKGROUND: Many clinicians use peripheral nerve blocks (NBs) and trigger point injections (TPIs) for the treatment of headaches. Little is known, however, about the patterns of use of these procedures among practitioners in the USA. OBJECTIVES: The aim of this study was to obtain information on patterns of office-based use of peripheral NBs and TPIs by headache practitioners in the USA. METHODS: Using an Internet-based questionnaire, the Interventional Procedures Special Interest Section of the American Headache Society (AHS) conducted a survey among practitioners who were members of AHS on patterns of use of NBs and TPIs for headache treatment. RESULTS: Electronic invitations were sent to 1230 AHS members and 161 provided usable data (13.1%). Of the responders, 69% performed NBs and 75% performed TPIs. The most common indications for the use of NBs were occipital neuralgia and chronic migraine (CM), and the most common indications for the use of TPIs were chronic tension-type headache and CM. The most common symptom prompting the clinician to perform these procedures was local tenderness at the intended injection site. The most common local anesthetics used for these procedures were lidocaine and bupivacaine. Dosing regimens, volumes of injection, and injection schedules varied greatly. There was also a wide variation in the use of corticosteroids when performing the injections. Both NBs and TPIs were generally well tolerated. CONCLUSIONS: Nerve blocks and TPIs are commonly used by headache practitioners in the USA for the treatment of various headache disorders, although the patterns of their use vary greatly.
