Load cell: a device to monitor weight bearing for lower extremity amputees

The PRS-Moore Load Cell for use in immediate postoperative prosthetic fitting for above- and below-knee amputees is described. The design incorporates an audible warning device which will sound whenever the wearer applies more than the predetermined weight on the affected limb. The device is easy to use in a clinical setting and can be incorporated into any endoskeletal pylon. The cost per unit is approximately $125, and the cell can be reused for successive patients.
