Back and spine decompression device
A spinal decompression system comprising an anchor portion and a working portion operatively coupled to the anchor portion. The anchor portion is adapted to anchor the spinal decompression system to a mechanical ground. The anchor portion comprises an anchor strap. The spinal decompression system comprises a pair of arm supports to support a user's arms in a raised position. The pair of arm supports are operatively coupled to the anchor strap to form a load path from the pair of arm supports to the anchor strap. A load cell is disposed in the load path to sense an applied load applied by the pair of arm supports. The pair of arm supports have an adjustable height to adjust the spinal decompression system to apply a desired load to the users arm to unload at least a portion of the user's bodyweight.
1 . A spinal decompression system comprising:
an anchor portion to anchor the spinal decompression system to a mechanical ground, the anchor portion comprising:
an anchor; and
an anchor strap coupled to the anchor;
a pair of arm supports to support a user's arms in a raised position; and
a load path from the pair of arm supports to the anchor strap, the load path comprising:
a crossbar operatively coupled to the anchor strap, wherein the pair of arm supports are coupled to the crossbar at spaced apart locations; and
a load cell disposed in the load path to sense an applied load applied by the pair of arm supports to the user's arms, wherein the pair of arm supports have an adjustable height to adjust the applied load.
2 . The spinal decompression system of claim 1 , wherein each of the pair of arm supports comprises a working strap coupled to a working end portion, wherein the working end portion of each of the pair of arm supports is adapted to support a respective arm.
3 . The spinal decompression system of claim 2 , wherein the anchor strap has an adjustable length that is adjustable to adjust a height of the pair of arm supports.
4 . The spinal decompression system of claim 2 , wherein the working strap of each of the pair of arm supports comprises an adjustable length working strap that is adjustable to adjust a height of the working end portion of the respective arm support.
5 . The spinal decompression system of claim 1 , wherein the spinal decompression system is door mountable.
6 . The spinal decompression system of claim 5 , wherein the anchor comprises a door wedge to support the door and wherein the anchor strap runs from the door wedge to a door top and passes between the door top and a door frame.
7 . The spinal decompression system of claim 1 , further comprising a harness to suspend the crossbar, wherein the harness is coupled between the crossbar and the load cell.
8 . The spinal decompression system of claim 7 , wherein the harness is adjustable to adjust a height of the arm supports.
9 . The spinal decompression system of claim 1 , wherein each of the pair of arm supports comprises an arm sling, a cuff, or a handle.
10 . The spinal decompressions system of claim 1 , wherein the load cell is a bending beam load cell disposed in an interior of the crossbar, and wherein the anchor strap is coupled to the bending beam load cell.
11 . The spinal decompression system of claim 1 , further comprising a controller coupled to the load cell, wherein the controller is configured to convert a signal output by the load cell to an indication of an unloading load applied by the spinal decompression system on the user's arms.
12 . A method for spinal decompression comprising:
anchoring a spinal decompression system to a mechanical ground, the spinal decompression system comprising:
an anchor; and
an anchor strap coupled to the anchor;
a pair of arm supports to support a user's arms in a raised position; and
a load path from the pair of arm supports to the anchor strap, wherein the load path comprises:
a crossbar from which the pair of arm supports are suspended; and
a load cell disposed in the load path to sense an applied load applied to the user's arms;
supporting the user's arms using the pair of arm supports;
adjusting the spinal decompression system to apply a selected unloading load to the user's arms, the selected unloading load selected facilitate spinal decompression; and
performing a spinal decompression session, comprising continuing to support the user's arms using the selected unloading load for a prescribed period of time.
13 . The method for spinal decompression of claim 12 , wherein the selected unloading load is 10%-30% of the user's body weight.
14 . The method for spinal decompression of claim 12 , further comprising converting a signal output by the load cell to an applied unloading load and outputting an indication of the applied unloading load, wherein adjusting the spinal decompression system to apply the selected unloading load to the user's arms comprises adjusting the spinal decompression system so that the indication of the applied unloading load indicates the selected unloading load.
