Abstract
The present disclosure is directed to muscle fascicle measurement systems and methods. A measurement device with electrodes placed in proximity to a target muscle of a subject's body. Stimulating signals may be transmitted by first electrodes placed along a muscle fascicle belonging to a particular muscle and the muscle response is sensed by second electrodes placed in proximity to the particular muscle. Signals sensed by the second electrodes are processed to determine one or more characteristics of the particular muscle fascicle and/or one or more characteristics of a nerve associated with the muscle fascicle.
Claims20
A system comprising:
- a first set of electrodes disposed in a first region corresponding to a set of a plurality of muscle fascicles of a subject;
- a second set of electrodes disposed in the first region corresponding to the set of the plurality of muscle fascicles;
- a stimulation device configured to:
- transmit a first signal to a first electrode of the first set of electrodes;
- and
- transmit a second signal to a second electrode of the first set of electrodes, the second signal having less power than the first signal;
- a sensing device configured to detect a first response signal using a first detecting electrode in response to transmission of the first signal and the second signal;
- and
- a processor configured to determine at least one feature of a first muscle fascicle among the set of the plurality of muscle fascicles based on the first response signal.
A method comprising:
- transmitting a first signal to a first electrode of a first set of electrodes, the first electrode disposed proximate to a first muscle fascicle;
- transmitting a second signal to a second electrode of the first set of electrodes, the second electrode disposed proximate to a set of additional muscle fascicles adjacent to the first muscle fascicle, wherein the second signal has less power than the first signal;
- detecting, using a second set of electrodes, a first response signal in response to transmission of the first signal and the second signal;
- detecting, using the second set of electrodes, a second response signal in response to transmission of the first signal and the second signal;
- receiving a reference signal from a reference electrode disposed in a region other than where the muscle fascicles are located, wherein determining the first feature of the muscle fascicle comprises determining the at least one feature based on the reference signal, the first response signal, and the second response signal and
- determining, by a processor, a first feature of the muscle fascicle based at least in part on the first response signal, the second response signal, and the reference signal.
