For more than 3,000 years, O&P devices have been enabling individuals to live fuller lives, and for the past ten years, The O&P EDGE has provided valuable, in-depth industry information for prosthetists, orthotists, pedorthists, and related allied healthcare professionals. As we continue our tenth anniversary celebration, we wanted to provide a visual grab bag of upper- and lower-limb O&P devices that have assisted people throughout the ages.

O&P technology has evolved from basic support aids to upper-limb passive hooks and lower-limb passive peg legs to microprocessor-controlled upper- and lower-limb prostheses and functional electrical stimulation (FES) devices. Today's researchers are working on neuroprosthetic technology— starting yet another chapter in prosthetics innovation.

Illustrations of transtibial sockets constructed from a combination of leather and wood, each with a rubber foot. The socket on the left is made to place a large amount of the wearer's weight on the extremity of the residual limb. The socket on the right is designed to hold the end of the residual limb away from the bottom of the socket, with the wearer's weight being distributed along the sides, above the knees, and around the top borders of the socket.
