EAnEAWN-Tinnitus

Details and patient eligibility

About

This randomized controlled trial aims to evaluate the efficacy and safety of either electroacupuncture alone or combined with warm needling in reducing tinnitus loudness and improving the impairment caused by tinnitus in Hong Kong.

Full description

This study is a prospective, multicenter, assessor-blind, three-arm, parallel-group, randomized waitlist-controlled trial. A total of 90 eligible subjects with tinnitus will be recruited and randomly assigned to electroacupuncture (EA), electroacupuncture combined with warm needling (EAWN) or waitlist control with n=30 subjects each group. The entire study period will last for 10 weeks, including a 5-week intervention period and a 5-week follow-up period. Outcome measures include the loudness of tinnitus and the Tinnitus Handicap Inventory. Any adverse event will be observed and recorded for safety assessment. The study findings will provide evidence to determine the efficacy and safety of electroacupuncture with or without combined warm needling for tinnitus in Hong Kong.
