Systems and processes for distraction control

A distraction system, comprising:

• a distraction implant comprising a magnetic element, a distraction mechanism configured to expand the distraction implant in response to rotation of the magnetic element, and a first near-field communication (NFC) device configured to store an implant identifier;
• and
• an external device comprising:
• a motor configured to rotate a driver magnet while in a powered state;
• the driver magnet configured to rotate the magnetic element;
• a second NFC device;
• and
• a computing device embedded in or in operative communication with the external device, wherein the computing device includes a processor programmed to execute the following instructions:
• determine an alignment between the distraction implant and the external device based on a first reading of the implant identifier from the first NFC device via the second NFC device;
• measure an electrical current drawn by the motor during rotation of the driver magnet;
• and
• maintain the motor in the powered state in response to:
• determining a continued alignment between the distraction implant and the external device based on a second reading of the implant identifier from the first NFC device via the second NFC device;
• a mean value of the electrical current being greater than or equal to a mean value threshold;
• and
• a standard deviation value of the electrical current being less than or equal to a standard deviation threshold.
