@Tinniger The theory is that adopted body posture or sometimes starting at birth has responsibility for most all with somatic tinnitus, but also for some with noise induced tinnitus. Improper muscle balance can effect all the major systems of the body. Joints and disc from muscle imbalance place pressure on nerves.
For those who start to do yoga with forward head bending will see nothing but body improvement unless they have muscular imbalances of the back, shoulder and cervical muscles. Those who start to run will see health benefits unless they have one leg much shorter than the other. The first thing that a chiropractor will do is measurements. Any NFL or sports doctor does the same.
I said to my neuro that I read a lot about those attending a concert and getting tinnitus where I don't read as much about those going to a movie theater getting tinnitus. He called me back in a week and said we have a research group on this. They have completed a small informal study on movie theater and concert goers. They found that those that attend a concert have 5X more onset of tinnitus over those that attend movies even when the decibel output was considered to be the same. They consulted audio sound engineers and said that there's nothing to explain this from their knowledge. A bigger study may take place to include body posture and forward head benders for movie and concert attenders per tinnitus.
