Parkinson en mouvement (PEM) is itself pursuing research to evaluate the impacts of it's programme. There are also many researchers out there looking at ways music, dance, movement, song & exercises may contribute to the well-being of people with PD. Here are some that have inspired us, or that may, once the results are known.
From Montreal, the BRAMS (the International Laboratory for Brain, Music and Sound Research, jointly affiliated with the University of Montreal and McGill) has discovered a link between dopamine production & music.
From Ontario, the SMART (Science of Music, Auditory Research and Technology Lab, Ryerson U) research team is looking into questions at the intersection of mind, music and technology. Dr. Russo is hoping to leverage the neural links between music, movement and emotion to help emotionally kick-start Parkinson's patients who've lost expressiveness.
From the USA, Dr Cynthia Fox of the National Center for Voice and Speech, (University of Colorado Boulder) is pursuing research on recent advances in neuroscience that suggest exercise-based behavioural treatments may improve function and possibly slow progression of motor symptoms in individuals with PD. The LSVT (Lee Silverman Voice Treatment) Programs for individuals with PD have been developed and researched over the past 20 years beginning with a focus on the speech motor system (LSVT LOUD) and more recently have been extended to address limb motor systems (LSVT BIG).
