1. A system for repetitive loading of a prosthetic socket, the system comprising:
a base;
a load cell coupled to the base;
a first coupling mechanism positioned vertically above the load cell, wherein the first coupling mechanism is configured to be removably coupled to a first end of the prosthetic socket;
a second coupling mechanism positioned vertically above the first coupling mechanism, wherein the second coupling mechanism is configured to be removably coupled to a second end of the prosthetic socket;
a rod having a first end and a second end opposite the first end, wherein the first end of the rod is coupled to the second coupling mechanism;
a motor coupled to the second end of the rod;
a support structure extending vertically from the base;
an actuator coupled to the support structure such that the actuator is positioned vertically above the second coupling mechanism; and
a curved rail coupled to the actuator and positioned between the actuator and the second coupling mechanism, wherein the curved rail is configured to contact the second coupling mechanism along an arc defined by the curved rail such that the second coupling mechanism moves along the arc when the motor moves the rod.
