Abstract: A garment-based system, construction and method controls knee brace displacement relative to a brace-outfitted lower extremity. The garment-based system includes or is cooperable with a knee brace, a waist-encircling anchor structure, an anchor-to-brace tether structure, and certain tether-to-brace attachment structures. The waist-encircling anchor structure is receivable about a user's waist and fixable in a transverse anchor plane. The inelastic anchor-to-brace tether structure is fastened to the waist-encircling anchor structure and extends in a first direction orthogonal to the transverse anchor plane. The tether-to-brace attachment structure(s) fasten the knee brace to the anchor-to-brace tether structure, and are immovable in the first direction.

Abstract: A knee brace functions to extensionally center and thereby enhance patellar function. The brace comprises an upper bracket assembly, a lower bracket assembly, and certain torsional spring assemblies. The upper and lower bracket assemblies comprise leg-receiving bracket portions and certain axial support structure extending from the bracket portions to bracket junctions. Each spring assembly comprises a torsional spring element and an elastically compressible core element. The torsional spring elements compressibly receive the core elements. The torsional spring elements are actuable for imparting restorative resistance forces, and the core elements function to damp the restorative resistance forces. The damped restorative resistance forces function to safely enhance quadriceps muscle contraction during knee extension. The enhanced quadriceps muscle contraction functions to center the patella during knee extension, and thereby enhance patellar function.

Abstract: The harness includes a torso engaging device made of nylon strips conformed in a figure eight pattern; the arms of the wearer extending through the loops. An arm cuff is also provided which engages about the upper arm of the wearer and is connected to the torso engaging device by means of rubber tubings which act to limit range of motion of the arm. Also, to keep the torso engaging device from riding up around the arms of the wearer, further rubber tubings engage a lower torso strip section to clips engaged to the harness wearer's belt. The harness can be used for either arm, or both arms, as desired. Also, with simple modifications, the harness could be used to control range of motion of other joints as well.
