RR= Respiratory Rate; Area = area of the ellipse that cover 95% of the center of pressure data points during one data collect session; Velocity = Average velocity of the center of pressure data points during one data collect session;V1=Visit 1: pre-intervention measures; V2=Visit 2: post-intervention measures; V2-V1= post-intervention – pre-intervention measures.
