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 in tinnitusworsening. 

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.
