Abstract

A therapeutic wrap is securable in an operative orientation around the forearm for relieving stress of the myofascial structures caused by repetitive motion and vibration trauma, such as "tennis elbow". The wrap has a circumference sufficient to encircle the forearm of a user and includes a pocket for accommodating a pressure pad having plural parallel aligned elongate chambers. The parallel aligned chambers of the pressure pad extend lengthwise in a direction parallel to a longitudinal axis of the forearm when the appliance is secured in the operative orientation. The pressure pad may be formed of an air bladder having plural parallel air chambers and a valve mechanism for allowing the user to increase an air pressure contained within the air bladder chambers.

Claims

1. A therapeutic appliance securable in an operative orientation around the forearm for relieving stress of myofascial structures caused by repetitive motion and vibration trauma, said therapeutic appliance comprising:

a wrap having a pocket formed therein and having a circumference sufficient to encircle the forearm of a user; and

,

a pressure pad, contained within said pocket of said wrap, having plural parallel aligned chambers extending lengthwise in a direction perpendicular to the circumference of said wrap and parallel to a longitudinal axis of the forearm when the appliance is secured in the operative orientation around the forearm such that the pressure pad follows the contour of the underlying limb and musculature of the forearm to inhibit movement of the appliance around the forearm during use.

2. A therapeutic appliance as recited in claim 1, wherein said pressure pad is an air bladder having plural parallel aligned elongate air chambers.

3. A therapeutic appliance as recited in claim 2, wherein said air bladder contains plural air ducts connecting said plural parallel aligned elongate air chambers such that a body of air contained within said air chambers is contiguous.

4. A therapeutic appliance as recited in claim 3, wherein said pressure pad further comprises an air valve mechanism located at a proximal end of said air bladder, said air valve mechanism operable by the user to increase the air pressure contained within said plural parallel aligned elongate air chambers.

5. A therapeutic appliance as recited in claim 2, wherein said pressure pad further comprises an air valve mechanism located at a proximal end of said air bladder, said air valve mechanism operable by the user to increase an air pressure contained within said plural parallel aligned elongate air chambers.

6. A therapeutic appliance as recited in claim 1, wherein said wrap comprises:

an elastic sleeve containing said pocket along an inner peripheral surface thereof; and

an inelastic strap, fixed to and extending along an outer peripheral surface of said elastic sleeve, including a fastener means for tightly securing said elastic sleeve in the operative orientation around said forearm.

7. A therapeutic appliance as recited in claim 2, wherein said wrap comprises:

an elastic sleeve containing said pocket along an inner peripheral surface thereof; and

an inelastic strap, fixed to and extending along an outer peripheral surface of said elastic sleeve, including a fastener means for tightly securing said elastic sleeve in the operative orientation around said forearm.

8. A therapeutic appliance as recited in claim 3, wherein said wrap comprises:

an elastic sleeve containing said pocket along an inner peripheral surface thereof; and

an inelastic strap, fixed to and extending along an outer peripheral surface of said elastic sleeve, including a fast fastener means for tightly securing said elastic sleeve in the operative orientation around said forearm.

9. A therapeutic appliance as recited in claim 8, wherein said pocket of said wrap includes an opening for allowing the user to removably insert said pressure pad into said pocket, and wherein said wrap includes a second fastening means for closing said opening of said pocket to secure said pressure pad within said pocket.

10. A therapeutic appliance as recited in claim 1, wherein said pocket of said wrap includes an opening for allowing the user to removably insert said pressure pad into said pocket, and wherein said wrap includes a fastening means for closing said opening of said pocket to secure said pressure pad within said pocket.

11. A therapeutic appliance as recited in claim 6, wherein said wrap includes a sheet of material secured to said elastic sleeve at said inner peripheral surface thereof, said pocket being defined between said sheet of material and said inner peripheral surface of said elastic sleeve, said pocket having an opening at an end of said sheet of material located adjacent a lateral edge of said elastic sleeve, and said sheet of material having a fastener by which said opening of the pocket can be closed by said sheet of material to secure said pressure pad within said pocket.
