An orthotic support comprises a shoulder section for encapsulating a first shoulder of a wearer, a glove section for conforming to at least a portion of the wearer's hand, and a sleeve section for conforming to the wearer's arm, the sleeve section connecting the shoulder section to the glove section. A resilient reinforcement extends from the glove section to the shoulder section, and at least a portion of the reinforcement extends in a spiral around the sleeve section, so that the reinforcement is configured to apply a rotational force to the wearer's arm, when worn, to urge a portion of the wearer's arm to rotate in a predetermined direction. The orthotic support may be usable to treat or prevent shoulder dislocation or subluxation, arm over-pronation or over-supination, wrist flexion or elbow flexion. An orthotic support may comprise a reinforcement with a first branch extending over an anterior portion of the sleeve section, and a second branch extending over a posterior portion of the sleeve section, so that the reinforcement is configured to urge the wearer's upper arm towards a rest position.

Joint Orthosis with Helical Supporting Structure
20220015938 · 2022-01-20 ·

A helical orthosis is an apparatus to support the function of an injured or impaired joint with a helical supporting structure mounted about the affected joint. The apparatus includes at least one helical coil, a primary band, and a secondary band in the preferred embodiment. A first end of the helical coil is slidably mounted to the primary band with the helical coil mounted in between the primary band and the secondary band along a helical path, wherein he helical coil exerts force against the primary band and the secondary band is support of the intermediate affected joint. Accordingly, a second end of the helical coil is slidably mounted to the secondary band contralateral to the first end of the helical coil. This configuration will enable a user to adjust the force exerted on the affected joint by traversing the helical coil about the limb into any desirable configuration.

Potentiating support with expandable framework

A method of donning a potentiating support for a hinge joint of a body includes positioning a garment proximate an area of a body; positioning an expandable and recoverable framework in abutment with the area of the body such that the framework spans a hinge joint of the body, the framework defining a plurality of permanent openings extending therethrough regardless of whether the support is donned; applying tension at points of the framework such that the framework is expanded and the framework is tensioned in its abutment with the area of the body, said step of applying tension being performed by pulling on one or more fastening components that are attached at one or more points to said framework; and affixing each of the fastening components to the garment while applying tension to the framework to secure the expanded framework in its forced abutment with the area of the body.
