Abstract
The motion of two pivotally connected orthosis members are limited in both directions of movement. An adjustable arresting member limits motion in one direction. An elongated member, preferably made of flexible cables, is connected to the two orthosis members to limit motion in the opposite direction.
Claims8
An orthotic device for a limb joint, said device comprising first and second members adapted, respectively, to be attached to portions of the anatomy on opposite sides of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis substantially corresponding to an axis of motion of the joint, an abutment carried by said first member, an adjustable arresting member carried by said second member and engagable with said abutment for arresting pivotal movement between said first and second members in one direction about the pivotal axis, means carried by said second member for adjusting said arresting member, and means for adjustably limiting pivotal movement between said first and second members in the opposite direction about the pivotal axis, said limiting means comprising an elongated member engagable with said first and second members, said elongated member comprising flexible.
An orthotic device for a limb joint, said device comprising first and second members adapted, respectively, to be attached to portions of the anatomy on opposite sides of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis substantially corresponding to an axis of motion of the joint, an abutment carried by said first member, a mounting block carried by said second member, an adjustable arresting member slidably carried by said mounting block and engagable with said abutment for arresting pivotal movement of said first and second members in one direction, an adjusting member threadably received in said mounting block and adapted to adjust said arresting member, said arresting member and said adjusting member having openings therethrough, a flexible cable member having one end thereof attached to said abutment, said cable member extending through the openings in said arresting member and said adjusting member, and an adjustable keeper member on the other end of said cable member for adjusting the effective length of said cable member in relation to said first and second members, said cable member serving to limit pivotal movement of said first and second members in the opposite direction.
An orthotic device for a limb joint, said device comprising first and second members adapted, respectively, to be attached to portions of the anatomy on opposite sides of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis substantially corresponding to an axis of motion of a joint, an abutment carried by said first member, a mounting block carried by said second member, an adjustable arresting member slidably carried by said mounting block and engagable with said abutment for arresting pivotal movement of said first and second members in one direction, an adjusting member threadably received in said mounting block and adapted to adjust said arresting member, a pair of flexible cables, each having one end attached to said first member, said flexible cables extending along opposite sides of said mounting block, and an adjustable keeper member carried by said mounting block for adjustably positioning the other end of each cable, said cables serving to limit pivotal movement of said first and second members in the opposite direction.
