This study tested whether a skin patch, worn behind the ear, could help reduce tinnitus (ringing or buzzing in the ears) in adults. Eighty participants took part. Half wore an active patch, and half wore a patch that looked the same but had no active effect (a placebo). Neither the participants nor the researchers knew who received which patch until the study ended.
All participants also received an educational counseling session about tinnitus and how to manage it. Participants were assessed before treatment, three weeks later, about seven weeks later, and again about one year later. The researchers measured how much tinnitus affected their daily life, their sensitivity to sound, and their anxiety or mood.
Inclusion Criteria:
Age older than 18 years Subjective tinnitus for at least 4 weeks Absence of dermatological conditions that could cause skin irritation from patch application
Exclusion Criteria:
Currently undergoing active tinnitus therapy Known skin sensitivity
Active and placebo patches were sealed in identical, indistinguishable envelopes by a third party, who recorded the allocation key separately. The investigator, who also served as the care provider and outcomes assessor (delivering counseling, dispensing patches, and administering weekly questionnaires), remained unaware of group allocation until the study concluded.
Participants applied an active steady-state coherent biomodulator patch (Antinitus, Sensori AB, Sweden) behind the ear daily for three weeks. All participants in this arm also received a standardized one-hour informative counseling session at study entry, covering the auditory system, tinnitus, and management strategies
Participants applied a placebo patch, visually indistinguishable from the active patch, behind the ear daily for three weeks. All participants in this arm also received the same standardized one-hour informative counseling session at study entry as the experimental group
