Gait Analysis for Tuning Transtibial Prosthetic Alignment

Quick fact

A slight change of just a few degrees in the socket flexion angle can significantly shift the ground reaction force line relative to the knee joint, affecting knee stability and walking energy expenditure by up to 10%.

Why this is interesting

Have you ever wondered why a person with a below-knee prosthesis might still walk with a limp, even with a high-tech artificial limb? The secret lies not just in the hardware, but in the meticulous tuning of its alignment—much like adjusting the wheels and suspension of a car for a smooth ride.
