Abstract

An back orthosis includes a lumbar panel, a support and a pair of cinching systems between corresponding sides of the lumbar panel and the support. The lumbar panel is configured to be positioned over a portion of the back of an individual'"'"'s torso (e.g., over a portion of the individual'"'"'s spine, etc.) and to apply localized or focused pressure to a portion of the back. The support is configured to extend over at least a portion of the front side of the torso and to be anchored by the front side. In addition, the support may include a pair of anchors that are configured to be positioned over lateral locations on the back. Each cinching system includes one or more cords and a system of rollers, or pulleys, with a set of rollers being associated with each outer edge of the support and another set of rollers being associated with each lateral edge of the lumbar panel. The rollers may be oriented non-horizontally and, along with their corresponding cord(s), may be configured maximize the amount of leverage that may be achieved with each cinching system and, thus, maximize the amount of force that the lumbar support may apply to the back.

Claims

1. A back orthosis, comprising:

a pair of rear anchors, each rear anchor of the pair being configured to be oriented substantially vertically and positioned over and secured against a lateral location on a back of a torso of a subject, the pair of independent rear anchors being configured to be positioned over and secured against lateral locations on opposite sides of and laterally spaced apart from a spine of the back;

a lumbar support positioned between the pair of independent rear anchors and oriented to be positioned over and secured against the spine to apply focused pressure along the spine while applying substantially no pressure to elongated locations of the back oriented substantially parallel to and located laterally adjacent to opposite sides of the spine; and

a pair of independent cinching systems, each cinching system of the pair;

being associated with a rear anchor and an adjacent lateral portion of the lumbar support located adjacent to that rear anchor; and

configured to define a distance between adjacent edges of the rear anchor and the adjacent lateral portion of the lumbar support,

the pair of independent cinching systems configured to operate together to define an amount of the focused pressure applied along the spine.

2. The back orthosis of claim 1, wherein portions of each cinching system of the pair that extend across the elongated locations of the back extend across the elongated locations while applying substantially no pressure to the elongated locations.

3. The back orthosis of claim 1, comprising:

an anterior element configured to be positioned over at least a portion of an anterior of the torso of the subject.

4. The back orthosis of claim 3, wherein the anterior element is configured to exert force against the anterior surface of the torso toward the spine.

5. The back orthosis of claim 4, wherein the anterior element and the pair or rear anchors are configured and arranged to apply force to the torso at locations that decompress the spine.

6. The back orthosis of claim 3, wherein the pair of rear anchors are located at or adjacent to opposite ends of the anterior element.

7. The back orthosis of claim 1, wherein each cinching system includes:

a first plurality of rollers at or adjacent to a medial edge of the rear anchor;

a second plurality of rollers at or adjacent to a lateral edge of the lumbar support that opposes the medial edge of the rear anchor; and

at least one cord;

carried by each roller of the first plurality of rollers and the second plurality of rollers;

extending between the first plurality of rollers and the second plurality of rollers; and

adjustably assembling the rear anchor and the lumbar support.

8. The back orthosis of claim 7, wherein each roller of the first plurality and the second plurality is configured to be oriented non-horizontally when the lumbar support and the rear anchor are positioned on a torso of a subject.

9. The back orthosis of claim 8, wherein each roller is configured to be oriented substantially vertically when the lumbar support and the rear anchor are positioned on a torso of a subject.

10. The back orthosis of claim 1, wherein the rear anchors are configured to be oriented at an angle to one another.

11. The back orthosis of claim 1, wherein an angle at which the rear anchors are oriented to one another and an amount of pulling force applied by each cinching system to its corresponding lateral edge of the lumbar support at least partially define the amount of the focused pressure applied to the spine.

12. A back orthosis, comprising:

at least one support configured to be positioned at least over at least a portion of a front side of a torso of a subject;

a lumbar support configured to be positioned over a portion of a back of the torso;

a pair of cinching systems, each cinching system;

extending between an outer edge of the at least one support and a lateral edge of the lumbar support; and

comprising;

a first plurality of rollers at or adjacent to the outer edge of the at least one support;

a second plurality of rollers at or adjacent to a lateral edge of the lumbar support that opposes the outer edge of the at least one support; and

at least one cord;

carried by each roller of the first plurality of rollers and the second plurality of rollers;

extending between the first plurality of rollers and the second plurality of rollers; and

adjustably assembling the rear anchor and the lumbar support.

13. The back orthosis of claim 12, wherein the at least one support is further configured to extend over lateral portions of a torso of a subject and comprises a pair of rear anchors configured to be positioned over lateral portions of the back of a torso.

14. The back orthosis of claim 12, wherein each roller of the first plurality and the second plurality is configured to be oriented non-horizontally when the lumbar support and the at least one support are positioned on a torso of a subject.

15. The back orthosis of claim 14, wherein each roller is configured to be oriented substantially vertically when the lumbar support and the at least one support are positioned on a torso of a subject.

16. The back orthosis of claim 12, wherein the pair of cinching systems are configured to be oriented at an angle to one another.

17. The back orthosis of claim 16, wherein the angle at which the pair of cinching systems are oriented to one another and an amount of pulling force applied by each cinching system to its corresponding lateral edge of the lumbar support at least partially define an amount of the focused pressure applied by the lumbar support to the spine.

18. A method for selectively applying focused pressure to a spine, comprising:

positioning a lumbar support on a back of a torso of a subject;

placing a support across at least a portion of a front side of the torso;

introducing tension into each cinching system of a pair of cinching systems that assemble outer edges of the support to lateral edges of the lumbar support,

the tension in each cinching system causing that cinching system to exert a pulling force on its corresponding lateral edge of the lumbar support,

angles at which the cinching systems are oriented relative to one another or relative to the lumbar support and an amount of the pulling force applied by each cinching system to its corresponding lateral edge of the lumbar support at least partially defining an amount of focused pressure applied by the lumbar support to the spine.

19. The method of claim 18, wherein introducing tension is effected by introducing tension into a system in which at least one cord is secured between the support and the lumbar support by a plurality of non-horizontally oriented rollers positioned adjacent to each outer edge of the support and each lateral edge of the lumbar support and along which the at least one cord travels.

20. The method of claim 18, wherein introducing tension includes introducing tension between rear anchors secured in place on lateral portions of a back of a torso of a subject and the lateral edges of the lumbar support.
