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.

[ I claim:] [1.] Apparatus for collecting surface electromyographic (EMG) signals from a patient, comprising:a support member;a plurality of electrodes retained in the support member in a predetermined pattern, for positioning on a surface of a patient in a location related to underlying patient anatomy, wherein each of the electrodes includes a patient-contacting electrode head, wherein each electrode head comprises a plurality of discrete patient-contacting pyramid projections for engaging the surface of the patient, and wherein each pyramid projection culminates in a pointed tip for enhancing contact with the surface of the patient;the support member being semi-flexible to conform to the external curvature of the patient to allow the electrodes to intimately contact the surface of the patient;the support member being sufficiently rigid to maintain the predetermined pattern of the electrodes relative to one another.
