Input: Question: Does prolonged use of wind or brass instruments alter lung function in musicians?
Answer: The results suggest that W/B musicians' do not have altered respiratory function when compared to a non-musical control group. However, increased R(rs6) may indicate inflammatory, remodelling or other pathophysiological processes associated with W/B playing. Although the difference between groups was small it warrants further investigation.
Output:
no
