Abstract :
A portable, microcontroller-based device that detects deglutition and provides audio biofeedback to lower the swallowing rate in patients with high rates of air swallowing is discussed. Two pairs of electrodes are attached to selected locations on the patient´s neck to transduce surface electromyogram (EMG) signals produced during swallowing. Combinations of parameters, derived from the EMG signals, are used to detect swallows and eliminate movement artifacts. The device computes the current swallowing rate and gives audio feedback to the patient if the rate exceeds a preset threshold. During feedback, the interval between consecutive swallows and the relative amplitude for each swallow are stored in memory
