Devices, methods,
software, and kits are provided for performing
oral therapy with
biofeedback to provide real-
time data for clinicians to aid in designing a customized therapy plan and track
patient compliance with a prescribed therapy
regimen. The device provides mouthpieces, which are capable of providing both passive and active
range of motion for the jaw. Inclusion of a distance sensor on the device allows measurement of mandible
range of motion or maximal interincisal opening. The force, applied to the upper jaw and lower jaw during
oral therapy, can be controlled by inserting springs into the device, which have different spring constants. The force on the jaw can further be adjusted by using spring offset inserts. In addition, the maximum
range of motion for the jaw can be set using interchangeable top limit brackets or a top limit bracket comprising an adjustable range of motion
limiter.
