An optical scanning microscope includes an illumination system having a light source portion emanating from a light source, first and second polarizing beam splitters, and first and second optical channels disposed between the beam splitters. The light source portion is configured to emit a first illumination light beam comprising light of a first main polarization direction and of a second main polarization direction. The first beam splitter is configured to guide the light primarily into the first and channels, respectively. The second beam splitter is configured to form a second illumination light beam from light of the first and second main polarization directions from the first channel and second channels, respectively. The first and second channels are configured to emit the light of the first and second main polarization directions from the first and second channels, respectively, so as to have different types of convergence.

A hinge for a brace comprises a tensioning element such as an inelastic cord for applying a restorative force to the hinge. A tensioning mechanism, preferably a hydraulic spring, tensions the cord as the hinge is moved from a rest position to a loaded condition. A tensioning member having a peripheral cam surface applies a tensioning force to the cord as the hinge is moved out of the rest position. The tensioning block and the anchoring block may be operatively geared together along an arc of motion so as to provide a generally symmetrical motion of the tensioning and anchoring portions relative to the gusset. When an external force is applied to move the hinge from the rest position the tension on the cord loads the spring, and when the external force is removed the spring applies a restorative force to move the hinge back to the rest position. Optionally the tensioning member may be configured to be disengaged and reengaged by an external actuator.

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.

An orthopedic device for treating musculoskeletal disorders of the lower limb. The device includes a leg portion, a foot portion, and a toe portion. The leg portion is rotationally coupled to the foot portion at an ankle joint. The toe portion is rotationally coupled to the foot portion at a toe joint. The foot portion is selectively positionable relative to the leg portion at the ankle joint such that the foot portion may be arranged in a plurality of an ankle angles including plantarflexed and dorsiflexed positions. The toe portion is selectively positionable relative to the foot portion at the toe joint such that the toe portion may be arranged in a plurality of toe angles relative to the foot portion including plantarflexed and dorsiflexed positions.

Dynamic arm brace assemblies and methods of use are provided herein. An example device includes a torso connection member securable to a torso of a patient, a forearm support member that couples with at least a forearm of an patient, the forearm support member couples with the torso connection member so as to fix an elbow of the patient proximate the torso, the forearm support member being pivotally coupled to the torso connection member to allow for an angle between the forearm support member and a coronal plane of the patient, and a dynamic tensioning assembly that externally rotates the forearm support member and selectively sets the angle so as to stretch a shoulder capsule (capsule and adjacent tissue(s)) affected with adhesive capsulitis, reducing the adhesive capsulitis.

A joint mechanism has a leg frame part and a thigh frame part pivotally connected to each other, a one-way clutch connected to the leg frame part and the thigh frame part so as to lock turning between the leg frame part and the thigh frame part and allow the turning in one direction only, and a connecting/disconnecting part to connect and disconnect the connecting state between the one-way clutch and the thigh frame part.

An apparatus for treating lower limb contractures is disclosed. The apparatus comprises a pair of multi-sectional soles, which are movably affixed to a connector via a pair of arms using fasteners. The pair of soles are configured to support the user's feet. Each sole comprises four flat-solid plates, which are pivotally connected via hinges/fasteners. The four flat-solid plates are configured to cover, support, and align the user's feet. The apparatus further comprises a pair of ankle supports, securely and adjustably affixed to each sole, configured to support the user's ankle and lower leg. The plurality of straps is configured to secure the sole to the user's feet and lower leg while lifting and lowering the feet using additional straps that are coupled to one or more loops of the four-flat solid plates of the soles, thereby treating the limb contractures by facilitating the opportunity for the repetitive movement of every single joint and muscle in the lower limb of a the user.
