Abstract
A mobility augmentation system interleaves afferent and efferent signals in a wearable stimulation array to suppress detected spasticity and stimulate intended movement. A set of electrodes of the array are used to detect a measure of spasticity of one or more muscles of the user and a set of afferent signals are selected based on the detected measure of spasticity. The array further identifies an intended movement of the user and selects a set of efferent signals based on the intended movement. The electrodes apply the set of afferent signals and the set of efferent signals over a same period of time such that the set of afferent signals and the set of efferent signals are interleaved.
Claims20
A method comprising:
- initializing a wearable stimulation array comprising a plurality of electrodes;
- detecting, using a set of the electrodes, a measure of spasticity of one or more muscles;
- selecting a set of afferent signals based on the detected measure of spasticity;
- identifying an intended movement of a user wearing the wearable stimulation array;
- selecting a set of efferent signals based on the intended movement of the user;
- and
- applying, by the set of electrodes, the set of afferent signals and the set of efferent signals over a same period of time such that the set of afferent signals and the set of efferent signals are interleaved.
A wearable stimulation array comprising a non-transitory computer-readable storage medium storing instructions for execution and a hardware processor configured to execute the instructions, the instructions, when executed, cause the hardware processor to perform steps comprising:
- initializing a wearable stimulation array comprising a plurality of electrodes;
- detecting, using a set of the electrodes, a measure of spasticity of one or more muscles;
- selecting a set of afferent signals based on the detected measure of spasticity;
- identifying an intended movement of a user wearing the wearable stimulation array;
- selecting a set of efferent signals based on the intended movement of the user;
- and
- applying, by the set of electrodes, the set of afferent signals and the set of efferent signals over a same period of time such that the set of afferent signals and the set of efferent signals are interleaved.
A non-transitory computer readable storage medium storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform steps comprising:
- initializing a wearable stimulation array comprising a plurality of electrodes;
- detecting, using a set of the electrodes, a measure of spasticity of one or more muscles;
- selecting a set of afferent signals based on the detected measure of spasticity;
- identifying an intended movement of a user wearing the wearable stimulation array;
- selecting a set of efferent signals based on the intended movement of the user;
- and
- applying, by the set of electrodes, the set of afferent signals and the set of efferent signals over a same period of time such that the set of afferent signals and the set of efferent signals are interleaved.
