A prosthetic finger assembly includes one or more integrated attachment points for a palmar strap to prevent a backplate bridging and migration. The palmar strap is integrally fixed to a first anchor of a radial metacarpophalangeal pivot, which is configured to connect to the hand of a user, and removably attach to a second anchor of an ulnar metacarpophalangeal pivot. The palmar strap is removably attached to the first anchor and integrally fixed to the second anchor.

An embodiment includes an apparatus for coupling a user to a robot to provide robot-assisted physical therapy to the user. Other embodiments are described herein.

System for connecting an orthotic device to a prosthesis or limb.

Textile assemblies may be incorporated into a textile strap and include a stretch textile substrate and a patterned textile laminate. The textile substrate has a width extending from a first edge to a second edge. The patterned textile laminate is non-stretch or low-stretch, and coupled to the stretch textile substrate. The patterned textile laminate has a plurality of holes formed therethrough, configured to enhance breathability of the textile assembly. A span of the patterned textile laminate has a plurality of gaps formed therethrough to create a gradient of flexibility and compliance within the span of the patterned textile laminate, such that the stretch of the textile assembly varies along a continuum across the width of the textile assembly. Straps and/or harnesses of various uses may incorporate such textile assemblies, including harnesses for supporting prosthetic limbs, climbing and safety harnesses, and military or policy duty belts.

A clasp mechanism includes a clasp for securing a first strap segment to a second strap segment. The clasp includes a cinch and a bracket. The clasp features a tensile, high-load catch feature for securing the clasp mechanism during wear and a compressive, low-load hold feature that provides toggle force resistance via strap material compression.

An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the socket system to the closed configuration.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

A prosthetic device and approach for amputee remediation addresses partial or complete replacement of digits, and leverages the use of the remaining functional digits for directing operation of the prosthetic digits. A complete prosthetic digit replaces an amputated digit from actuated movement driven by an adjacent functional digit. A partial amputation leverages residual movement from the remaining digit portion as input to an actuator for amplifying the intent of the input through a motorized actuator to impart movement to the prosthetic digit. A wrist harness supports the apparatus of partial and complete prosthetic digits as a single appliance. A variable compression feature augments tension on the wrist harness to tightly engage the prosthetic appliance to the wrist to offset a gripping load on the prosthetic digits.
