  • Patent number: 10792183
    Abstract: A support assembly for a portion of a user's body includes a pivotable frame with a top elongated member, a bottom elongated member, a first side member and a second side member, the top elongated member and bottom elongated members each having first and second ends that are pivotably connected to top and bottom ends of the first side member and the second side member, respectively. A support element is operatively connected to the pivotable frame and a tensioner mechanism is adapted to adjust an amount of force required to move the support element relative to the first side member. The tension member is disposed within one of the top and the bottom elongated member and exerts a tensile force parallel to the longitudinal center axis of the one of the top and the bottom elongated member.

  • Patent number: 9764190
    Abstract: A dynamic hand splint including a hand support section, a sleeve configured to receive a digit therein, and a first tensioner having an elastic body and forming a loop, wherein the first tensioner is attached to the hand support section, as well as a first location of the sleeve, such that the first tensioner extends from the hand support section to the first location and a first joint of the digit. The elastic body of the first tensioner has sufficient flexural strength to resist, but not prevent, bending of the digit received within the sleeve such that, when the digit is flexed from an extended position toward a flexed position, the elastic body of the tensioner is elongated with the digit and the digit is urged by the tensioner toward the extended position.

  • Patent number: 7458947
    Abstract: A dynamic splint assembly for a hand includes a forearm support section configured to abut the dorsal side of a forearm and span a wrist; and a hand support section connected to the forearm support section. The hand support section is configured to abut the dorsal side of the hand including the dorsal side of the length of a finger. The hand support section comprises a resilient material that, in response to bending, such as during flexion of the finger, generates a continuous restoring force in opposition to such bending, whereby the finger in flexion is urged toward extension. The forearm support section, in contrast, does not generate, in response to bending, a continuous restoring force in opposition to such bending, whereby a wrist may be selectively oriented in one of many fixed dispositions having varying degrees of flexion and extension relative to a forearm.
