Systems and/or methods for assessing neuromuscular block status without stimulation

A neuromuscular block characterization system, comprising:

• a muscle movement measurement device configured to generate, unprompted by impulse stimulation to a subject from an external source, at least one signal representative of muscle movement measurements at at least one location of a body of the subject while the subject is experiencing neuromuscular paralysis caused by biophysiological processes at neuromuscular synapses throughout the body including remote from the at least one location;
• and
• processing circuitry configured to run a neuromuscular block analysis module, the module being configured to receive the at least one signal, analyze the muscle movement measurements embedded in the at least one signal, and determine a degree of neuromuscular blockade associated with the neuromuscular paralysis being experienced by the subject based on the analysis,
• wherein the processing circuitry is further configured to generate, for display via a display device, an indication of the degree of the neuromuscular blockade at each said location on the body,
• wherein the at least one location is selected based on a predefined surrogate mapping that indicates which signals from which surrogate locations inform on different areas of interest on the human body, and
• wherein the processing circuitry is further configured to provide a control signal to control administration of a neuromuscular blocking agent based on the determined degree of the neuromuscular blockade at each said location on the body.
