1. A method of supplying an electrical signal for muscle stimulation to body tissue that is in contact with muscle tissue, comprising the steps of: placing an electrode matrix (13) including a plurality of electrodes (12) in electrical contact with said body tissue ； - activate the indicated electrodes (12) in accordance with a sequence of activation schemes, each activation scheme defining a subset of activated electrodes (12), each corresponding subgroup consisting of at least one electrode (12), applying an electrical signal of muscle stimulation to the specified body tissue through at least one electrode (12) from the corresponding subgroup, and - measure, in turn with the indicated activation of the electrodes (12) in accordance with the activation circuit, the response signal associated with the activation circuit by registering a parameter of said muscle tissue, which generates an activity value of said muscle tissue in response to an electrical stimulation signal supplied through said at least one electrode (12) of an activation circuit into said tissue ate in contact with the specified muscle tissue. 2. The method according to claim 1, further comprising the step of: - selecting at least one of the plurality of electrodes (12) based on the measured response signals. A method according to claim 2, wherein said at least one of the plurality of electrodes (12) is selected based on a criterion suitable for determining muscle activity based on a response signal. The method according to claim 2, further comprising the step of: - selectively supplying through said selected at least one electrode (12) and1. Способ подачи электрического сигнала стимуляции мышц в ткань тела, которая контактирует с мышечной тканью, включающий в себя этапы, на которых:- размещают матрицу (13) электродов, включающую в себя множество электродов (12), в электрическом контакте с указанной тканью тела；- активируют указанные электроды (12) в соответствии с последовательностью схем активации,
