Adaptive stimulation array for motor control

A method comprising:

• initializing a wearable stimulation array comprising:
• a set of configurable electrodes each configured to contact a different portion of a surface of a body of a user when the wearable stimulation array is worn by the user;
• a power source;
• a memory storing a machine-learned movement model trained using measured movement data associated with respective actuation instructions, the movement model configured to determine actuation instructions likely to stimulate a set of movements, each actuation instruction specifying an electrical signal to be transmitted from a given electrode to a different electrode;
• and
• a controller coupled to the set of configurable electrodes, the memory, and the power source;
• stimulating a first movement of the set of movements by configuring current from the power source to flow in a direction between a first electrode and a first set of electrodes such that the first electrode is configured to operate as an anode;
• and
• stimulating a second movement of the set of movements by configuring the current to flow in a different direction between the first electrode and a second set of electrodes such that the first electrode is configured to operate as a cathode.

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 set of configurable electrodes each configured to contact a different portion of a surface of a body of a user when the wearable stimulation array is worn by the user;
