  • One aspect of this disclosure relates to diagnostic methods, systems, and devices that can help assist in making a more objective assessment or determination about the initial shape of a wearable therapeutic brace to be used to treat one or more spinal deformities. Every patient can have a different degree of spinal deformity, and thus patient specific braces are desired and more effective.
  • a standard approach for creating a therapeutic brace initially involves either scans or caliper measurements of a patient in a standing or prone position. This provides a gross assessment of the patient's body surface for input into the brace building process. The brace maker then relies on two inputs for determining how much the spine can be corrected while the patient would still be comfortable in that brace.
  • the methods herein provide simple and accurate means of providing the patient and the orthotist to collaborate and agree on the forces and comfort that are required before taking these measurements. The resulting measurements will then consistently produce comfortable and clinically effective braces for any orthotist.
  • the improved methods herein utilize one or more signals sensed from a diagnostic system that is configured and adapted to interface with the patient.
  • the diagnostic methods include interfacing discrete portions of the patient's torso with separate interface assemblies of a diagnostic system.
  • the interface assemblies apply corrective forces to the patient's torso (similar to how the brace may apply forces to the patient).
  • the brace maker can then use one or more imaging modalities to generate a "corrected scan" of the patient.
  • the brace maker can then use that corrected scan when 3D modeling the therapeutic brace.
  • the systems and methods herein can provide actual force measurements applied to the patient as well as an image of the "corrected" patient.
  • the inclusion of patient comfort is a big step. It has been shown that comfort drives brace wear time, and that outcomes are driven by brace wear time, therefore comfort is directly related to outcomes. A further benefit is having comfort expectations established up front. Final fitting is 2-4 hour appointments and we expect to reduce the time required to create a brace to treat the deformity and improve the initial fit of the brace.

  • the distenders in some embodiments additionally comprise a monitoring member adapted to monitor displacements particularly in the plane including by the two frame elements 102.
  • Each of the distenders 101 interface with a frame structure or element 102.

  • the distender interfaces may comprise any selection or combination of foams, fluid or air filled bladders, and elements adapted and configured to conform to the contour of the body being evaluated.
  • Each distender interface may additionally comprise any selection or combination of an interface surface providing contrast in the generated image, pressure sensors, and load/force sensors. Pressure and load/force sensors allow for the characterization of the pressures associated with the distenders (e.g., air pressure within a bladder) and forces generated by the distenders on the patient's body.

  • the distenders interface the stand elements such that they can move towards and away from the patient.
  • the interfaces can be adapted to move with respect to the distender, such as with one or more degrees of freedom. This freedom of movement allows the distender interface to orient itself when the interface it placed in contact with the patient such that the distender interface has a better fit with the patient. Knowing the orientation of the interface surface in a reference 3D space when applying the corrective forces allows the system and/or brace maker to more reliably form the brace so that that portion of the brace has a similar orientation in the final brace.
  • the distender interfaces can have one or more radiopaque markers that allow their location and/or orientation to be monitored when visualized with a radiographic imaging modality.

  • the system can be adapted so that there can be any combination of degrees of freedom between frame element 102' and distender 101 ', and distender 10 ⁇ and interface 103'. This allows for degrees of freedom where frame element 102' interfaces distender 101 ', as well as where distender 10 interfaces with patient interface 103'.

In any of the embodiments herein they may alternatively be embedded within the surfaces of the existing brace material. As a pad normally sits on the top of the brace, we may integrate to the geometry conforming bladder is within the material of the brace as well.
  • Any of the restoring pads herein can also be used or integrated into any of the diagnostic systems, devices, and methods of use described herein.
  • the disclosure herein also provides for systems for and methods of identifying the location of and forces sufficient to reduce pain, which can be diagnostic in nature.
  • the diagnostic devices herein such as in the embodiment in figure 1 , can also be or alternatively used to identify the location(s) and/or forces sufficient to reduce pain.
  • a subject with back/spine pain can stand within the system, and the distender interfaces can be modified to contact the subject.
  • At least one of the interfaces can include a bladder and sensor as described herein. The at least one bladder can then be inflated while sensing force and/or pressure. Force and/or pressure can be monitored as set forth herein, and pain level can be assessed during the procedure (e.g., continuously).
  • Pain level assessment can include the subject indicating pain level on almost any type of scale, such as 1 -10; pain/no pain (binary), etc.
  • the force and/or pressure can be recorded (using any device, component, or method herein), and this allows a brace to be more efficiently made (as set forth herein) that can reduce the subject's pain when the brace is worn.
  • any of the diagnostic approaches herein can additionally (or alternatively) be used as part of a diagnostic assessment that can be used to create a therapeutic brace that can be used to treat pain (which can also be used to treat scoliosis as well).
  • the disclosure herein also provides methods of and systems adapted to monitor compliance and provide compliance information to a subject.
  • the compliance of a wearable device such as a therapeutic scoliosis brace, can be determined with the use of a thermal sensor secured to the wearable device, wherein the thermal sensor is set to close to body temperature threshold. So when a subject is wearing the wearable device, the thermal sensor senses the subject's body temperature, and can provide input to a computer executable method that can determine how long the subject was wearing the device over a given period of time (e.g., a day).
  • An alternative method of calculating compliance of a wearable device can be to utilize one or more biological dynamic variables, such as the subject's respiration cycle and ballistic cardiography.
  • biological dynamic variables such as the subject's respiration cycle and ballistic cardiography.
  • the force and/or pressure sensors will generally be able to sense a cyclical increase and decrease in the force and/or pressure as the subject exhales and inhales. Inhalation will cause an increase in sensed force and/or pressure, while exhalation will cause a drop in sensed force and/or pressure.
  • a computer executable method can be adapted to analyze the sensed force and/or pressure over time, and detect the cyclical increase and decrease, providing an indication that the wearable device is being worn. An aggregate period of time during which the wearable device is worn can be determined, and the method can output to a display on a user's device information that is indicative of compliance.
  • Other biological dynamic variables may also be able to provide an indication of compliance.
  • Ballistic cardiography has also confirmed that patient compliance can be sensed with an accelerometer alone, wherein the accelerometer can determine body position, and that the wearable device is being worn about the body.
  • a wearable device can have an accelerometer secured thereto.
  • the accelerometer can provide input to a computer executable method that can determine that the wearable device is being worn about a subject.
  • the same compliance calculations set forth above can be used, and the compliance can be output to a display on the user device.
