A method and apparatus for conducting electromyography of a deep muscle non-invasively are provided. An array of suitable surface electromyography electrodes (3) is arranged in one or more rings encircling a part of the human body in which a deep muscle (c) being investigated is located. The potential of at least selected electrodes relative to another electrode selected from a common reference electrode (mono-polar) and other electrodes (bi-polar) in the array is recorded and the data is processed in respect of the recorded potentials of at least some of said selected electrodes in order to determine (optionally using approximations or algorithms, or both) the contribution being made by at least the deep muscle being investigated. Typically, this is done mathematically by resolving the electromyography signals into their constituent components using a suitable technique. Preferably, this is integrated with a static muscle imaging device that may use the same electrodes to obtain a static tomogram of the muscles encircled. |
