1. A method of training an unaffected hand of a user with mobility restrained by a prosthesis simulator that matches a length of an unaffected anatomical arm of the user when worn and using the unaffected hand to perform a task that an affected hand comprising a partially amputated hand can perform using a prosthesis comprising:
restraining portions of the unaffected hand in an open hand posture with the prosthesis simulator to restrain mobility of the unaffected hand comprising:
restraining one or more fingers of the unaffected hand of the user of the prosthesis simulator;
and restraining a thumb of the unaffected hand of the user of the prosthesis simulator;
and performing the task with at least one or more artificial digits of the prosthesis simulator;
wherein the restraining and performing of the task by the unaffected hand trains the affected hand to perform the task with at least one or more prosthetic fingers and a prosthetic thumb of the prosthesis;
wherein the one or more artificial digits form at least a portion of a three jaw chuck grasp with the thumb and the thumb is constrained at a right angle to and secured along a palm of the unaffected hand.
