A bioelectric therapy system includes a pulsed electromagnetic field module for tissue conditioning and, in some embodiments, a grounding interface configured to electrically couple a subject to a ground reference; a bioelectric stimulation module configured to deliver a regulated, current-limited stimulation signal in a selected low-voltage range via a practitioner-assisted conduction path; and an analyzer configured to acquire measurable biophysical signals to generate assessment data representing physiological parameters. A control unit coordinates a protocol including conditioning, grounding, and stimulation, modifies at least one stimulation parameter based on assessment data or a monitored electrical characteristic, and generates a health assessment report (e.g., a color-coded assessment report) for longitudinal tracking.

This invention relates to the field of electromagnetic field control technology, specifically to a control system for pulsed electromagnetic fields used in the repair of peripheral nerve injuries. The system acquires the action potential voltage amplitude of each spatial node within the coil's coverage area, calculates the pre-stimulation conduction blockage coefficient based on the voltage distribution and time delay correlation of adjacent nodes, identifies blockage nodes, determines the principal normal direction of the blockage region through principal component analysis, and generates a theoretical output current value by combining the coil's projected area in that direction with the blockage coefficient. Subsequently, a low-frequency test pulse is applied, the post-stimulation conduction blockage coefficient is acquired, and a stimulation intensity correction coefficient is calculated. Finally, the corrected actual output intensity is used as the execution parameter for the next round of test pulses, forming a closed-loop adaptive control. This invention overcomes the problem that traditional uniform stimulation parameters cannot match the electrophysiological heterogeneity of nerve injury regions, achieving spatially precise and functionally adaptable electromagnetic control.

A system and method for pulsed electromagnetic fields (PEMF) tissue engineering enhances musculoskeletal tissue stimulation. A tissue engineering device may include both low and high pulse frequency signal generation components that may alternatively drive one or more coils to generate PEMFs. These PEMFs may be applied to bone tissue, tendons, ligaments, and / or cartilage. A prescribed treatment regimen using the tissue engineering device may include a first period of time where a first pulse frequency is used in treatment that supports tissue proliferation followed by a second period of time where a second pulse frequency (less than the first pulse frequency) is used in treatment that supports tissue differentiation. A treatment regimen may also include, with the frequency characteristic, applying a slew rate to the pulse characteristics that is on the order of around 30 to 100 Tesla per second to drive tissue differentiation in a targeted manner.
