1. A computerized system configured to calibrate performance of one or more statistical models used to generate a musculoskeletal representation, the system comprising:a plurality of neuromuscular sensors configured to continuously record a plurality of neuromuscular signals, wherein the plurality of neuromuscular sensors are arranged on at least one wearable device; and

at least one computer processor programmed to:

process at least some of the plurality of neuromuscular signals using a statistical model to generate based, at least in part, on joint angle estimates and/or force estimates output from the statistical model, the musculoskeletal representation;

determine based, at least in part, on at least one aspect of the musculoskeletal representation, that calibration of the statistical model used to generate the musculoskeletal representation is needed;

initiate a calibration session in response to determining that calibration is needed;

update a statistical model configuration based, at least in part, on a plurality of neuromuscular signals recorded by the plurality of neuromuscular sensors and ground-truth data representing position information and/or force information recorded during the calibration session to produce an updated statistical model;

process at least some of the plurality of neuromuscular signals using the updated statistical model to generate an updated musculoskeletal representation;

determine, based, at least in part, on the at least one aspect of the updated musculoskeletal representation whether further calibration of the statistical model is needed; and

end the calibration session in response to determining that further calibration is not needed.
