A system for detecting and analyzing electrical activity in the anatomy of an organism underlying an electromyographic (EMG) sensor device provides signals corresponding to electrical activity adjacent each electrode of sensor device. A method using the system may comprise determining EMG data for a patient using the EMG sensor device. The method may further include determining whether the determined EMG data for the patient corresponds to predetermined EMG data associated with at least one of a facet condition, a disc condition, and a muscle condition.

EMG diagnostic system and method

A system for detecting and analyzing electrical activity in the anatomy of an organism underlying an electrode array provides signals corresponding to electrical activity adjacent each electrode. Such signals are correlated to the underlying anatomy of the organism and representative outputs presented through various types of output devices. Such outputs may include variations in coloration or other qualities in correspondence with representations of underlying anatomical structures. The system includes electrode structures and methods for producing and attaching electrode arrays to the organism. The exemplary form of the invention is used in connection with the diagnosis of muscle activity in the lower lumbar regions of humans. Levels of muscle activity detected are analyzed by correlation with the muscular structures underlying the electrode array. Forms of the invention may be used in other applications.

Emg electrode apparatus and positioning system

An electrode for collecting surface electromyographic (EMG) signals consists of a generally bolt-shaped structure having a circular signal-gathering head and an integral shaft for support purposes and for transmission of electrical signals. The head of the electrode is configured as a disc having a plurality of pyramids distributed substantially evenly over the signal gathering surface with the tips of the pyramids projecting outwardly of the head for contact with the skin of a patient. Preferably, the electrode consists entirely of 316L stainless steel, the pyramids are formed by grinding or electromachining and the shaft is threaded for receipt of a clamp nut. The electrode is adapted for mounting in a hole in a thin, flexible support member by means of the shaft to maintain spacing among adjacent electrodes and to assure proper contact with the patient.

EMG electrode

A generally flat, rectangular rubber pad supports (63) discrete, non-invasive electrodes in a 7 by 9 array and a ground electrode to collect surface electromyographic (EMG) signals from an underlying muscle group of a patient. Electronic apparatus conditions the EMG signals and is programmed to survey the electrode array simultaneously to provide a description of the activity of individual muscles in the muscle group at that point in time. The description is displayed on a video monitor or the like, juxtaposed over a display of normal muscle anatomy, with differences being emphasized by color enhancement. The electrode pad is particularly suited for the lower back muscle groups and may be retained in position by a lumbar support belt having a pad molded to the contours of the human spine.

Computerized EMG diagnostic system

An electrode array for collecting surface electromyographic (EMG) signals from a patient consists of 63 electrically conductive electrodes supported in a non-conductive, flexible pad in a predetermined pattern of nine rows and seven columns of equally spaced electrodes. The flexible pad allows the electrode array to conform to the external curvature of the patient, while the 9.times.7 rectangular array of electrodes provides a unique pattern related to the configuration of underlying muscle groups of the patient. This allows the sensor pad to be uniquely positioned relative to the patient's anatomy and to provide signals representative of the muscle activity, which can then be electronically displayed in a corresponding pattern, for evaluation by the attending physician.
