By Emilie Hackett, Special to the Record – Singing is not just a hobby at the Research Centre on Aging (CdRV) in Sherbrooke. It is also a method of pulmonary rehabilitation for people affected by chronic obstructive pulmonary disease (COPD). Unconventional yet functional, choral singing significantly helps improve participants’ medical treatments. Not only does the choir, called the Joyeux Lurons, provide non-medical support to its participants, involvement with the choir could help improve lung function while exercising cognitive abilities and improving the patients’ quality of life.
