Abstract: 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.
