Didgeridoo playing as alternative treatment for obstructive sleep apnoea syndrome: randomised controlled trial

and now for a word from the battle front...

I am a professional tuba player of 43yrs and have played the tuba
since the
age of 12 (also known as bass tuba or contrabass tuba).

I have a light form of Apnoea and have been under
observation/treatment
since 2002 via the Sloterdijk Hospital (Ziekenhuis) in Amsterdam, the
Netherlands.

My response is more of 2 questions.

1.If the pure low vibrations of didgeridoo playing are assisting in
the
reduction of Apnoea symptoms, than why isn't the same affect achieved by
playing the tuba?

2.If the pure physical playing of a didgeridoo reduces Apnoea
symptoms,
than how does it differ from that of playing the tuba? The usage of the
circular breathing technique on the didgeridoo is the only difference
between
the two playing techniques that I am aware of.

(circular breathing involves filling the cheeks with air from the
lungs, then
expelling this air by contracting the cheeks. At the precise moment of
check
contraction a second action is performed of filling the lungs with air
through
the nose. In this way, a continuous stream of air is pressed through the
lips,
allowing them to continually vibrate thus producing a continuous sound.
Generally speaking, a tuba is mostly played by simply filling the lungs
with
air, expelling that air directly, and stopping the sound production to
fill the
lungs once again with air.)
