Patent ID: 7593768

Claim:
A system for detecting action potentials of smooth muscle motor activity in two or more digest tract organs in a subject's body, the system comprising: (a) one or more cutaneous electrodes recording at least one analog signal in the subject's body, the electrodes being attached to the subject's limbs; (b) an analog to digital converter converting each of the at least one analog signal to a digital signal; and (c) a programmable processor processing the one or more digital signals and programmed for: (ca) obtaining a power spectrum of one or more of the at least one digital signal; (cb) identifying two or more frequency peaks in one or more of the one or more power spectra, the frequency peaks corresponding to respective organs of said two or more digestive tract organs; and (cc) for each of the two or more organs in the subject's body, (cca) identifying a peak for the respective organ in the obtained power spectrum within a frequency range in which the respective organ generates slow waves; (ccb) determining an area under the identified frequency peak in the obtained power spectrum as an energy, E; and (ccc) determining whether the energy E exceeds a predetermined threshold value, an energy E greater than the predetermined threshold being indicative of action potential of smooth muscle motor activity in the respective organ in the subject's body.
