I walked behind a man with a prosthetic leg and marveled at how natural his gait was.
In older times, protheses design and construction was more of an art than a science.
And as such was very expensive.
Even still today, each prostheses has to be custom matched to the remaining limb, or if both limbs are missing must be matched to the patient’s previous height.
I’ve wondered why they don’t make them adjustable. Maybe they do.........
