NCT05961501

Brief Summary

The aim of the study is to evaluate the effectiveness of an aqueous solution containing CBD and CBN in the management of Facial Pain and Headache of Muscular Origin. A randomized (block randomization), double-blind, two-arm controlled trial will involve 42 adult patients diagnosed with Facial Pain and Headache of Muscular Origin which is lasting more than 3 months on the basis of clinical examination. Qualified study participants will be randomly assigned to two groups. The studied group will receive tan aqueous solution containing CBD and CBN, to drink at home in the dose determined by the attending physician, while the control group will receive an aqueous solution of placebo, to drink at home in the dose determined by the attending physician during this time. Each subject will be tested on the qualification day (D0), on 20 days after D0 (D20), and then 40 (D40) and 60 (D60) days after the qualification day using electromyography (EMG), pressure pain threshold test (PPT), clinical examination and surveys.

Outcome Measures

Primary Outcomes (2)

  • The influence of an aqueous solution containing CBD and CBN on muscle pain assessed using pressure pain threshold test (PPT) using the Wagner Paintest FPX 25 algometer.

    Each participant will undergo pressure pain threshold test (PPT) using the Wagner Paintest FPX 25 algometer before and after taking an aqueous solution containing CBD and CBN.

    3 months

  • The influence of an aqueous solution containing CBD and CBN on electrical activity and nerve conduction in muscles using EMG ( Electromyography).

    Each participant will undergo EMG ( Electromyography) before and after taking an aqueous solution containing CBD and CBN. EMG measures the electrical activity of the muscle during rest, slight contraction and forceful contraction.

    3 months

Secondary Outcomes (13)

  • The effectiveness of an aqueous solution containing CBD and CBN reduction on Facial Pain and Headache of Muscular Origin assessed by clinical examination in accordance to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) protocol.

    3 months

  • The influence of an aqueous solution containing CBD and CBN on reduction of Facial Pain and Headache of Muscular Origin using Pain Numerical Rating Scale.

    3 months

  • The influence of an aqueous solution containing CBD and CBN on muscle pain assessed using Graded Chronic Pain Scale.

    3 months

  • The influence of an aqueous solution containing CBD and CBN on muscle pain assessed using McGill Pain Questionnaire.

    3 months

  • The influence of an aqueous solution containing CBD and CBN on muscle pain assessed using Pittsburgh Sleep Quality Index.

    3 months

  • +8 more secondary outcomes
