- Primary Outcome Measures
Name Time Method Swallowing accuracy will be assessed by the peak-target error.<br>Each swallow of the participants will be displayed as a waveform on the computer screen by measuring muscle activity via surface electromyography. The participants will be asked to swallow such that the peak of the waveform hits a small target on the screen.<br>The peak-target error will be generated out of the two distances (along the X- and Y-Axis) between the target and the actual swallowing performance (peak of the displayed sEMG data taken from muscles involved in swallowing) of the participant in each trial. The error will be calculated as: z= [(Ax/trial length)^2+ (Ay/calibration value)^2]^(1/2)[Baseline measurements and assessment swallows over four sessions (2 consecutive days, follow-up on day one and day seven after the training).]
