Objectives: We sought to study the reliability of tinnitus modulation
by muscle contractions and to observethe effect of their prolonged repetition.
Methods: Thirty-eight patients with tinnitus underwent 9 maneuvers
of muscle contractions in test and retest situations.
After a 2-month
training period of repeating the maneuvers, tinnitus modulation and daily
perception were evaluated.
Results: There was no difference between the occurrence of tinnitus
modulation in test (57.9%) and retest (63.2%) situations.
After 2 months,
the occurrence of modulation during the maneuvers was similar (55.3%),
but a new pattern showed an increase in tinnitus improvement and a decrease
The daily perception of tinnitus was unchanged.
Conclusions: Maneuvers of head and neck muscle contractions evoked
tinnitus modulation in a frequent and reliable manner.
Also, the repetition
of such maneuvers for 2 months altered the pattern of modulation.
