Mark, Could you please elaborate on the rationale for studying the effect of voice training on gait? My only guess is that the breathing component of voice training does something to benefit overall fitness, but I don't get the exact connection. As you know, my research focusses on voice and speech in PD, and we often compare the "midline" structures involved to peripheral structures (arms, hands). Perhaps you are alluding to a relationship between balance and voice because they both involve axial (midline) structures? Thanks for clarifying. Nancy Solomon
