Clinical Trial: Clinical Efficacy and Peripheral Ultrasound Mechanism of Trigger Point Bloodletting Therapy for Primary Trigeminal Neuralgia

U.S., Aug. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07750730) titled 'Clinical Efficacy and Peripheral Ultrasound Mechanism of Trigger Point Bloodletting Therapy for Primary Trigeminal Neuralgia' on July 31.

Brief Summary: This randomized controlled trial integrates baseline observational ultrasound analysis to assess the clinical efficacy of trigger point bloodletting therapy for primary trigeminal neuralgia and explore peripheral ultrasound mechanisms of trigger point lesions and treatment response. Eligible subjects are adults aged 18-75 with unilateral classic primary trigeminal neuralgia and confirmed trigger points in the orbicularis oris muscle.

The primary research question is whether 8-week t...
