One afternoon last summer, a team of prosthetic technicians hovered around Adam Taylor as if he were a racecar in for a pit stop.

The length of Mr. Taylor’s new right leg was off, so a technician rushed away to shorten it at a pipe cutter. An additional fabric liner was added to Mr. Taylor’s residual limb. But it was too tight, so the additional liner was removed to allow better suction for the prosthesis. Another technician knelt on the floor, fiddling with the alignment of the new foot.

When Mr. Taylor’s leg was fitted and he had on a new pair of Nikes, Chris Kort, the owner of Prosthetics in Motion, based in Manhattan, pointed him to a wheelchair for the 60-foot trip to a parallel bar walkway.

“Why can’t we walk there?” Mr. Taylor asked, with a mix of urgency and agitation.

At the end of the five-hour appointment, Mr. Taylor, 36, walked out of the office on two legs, joining the ranks of thousands of New Yorkers who use artificial limbs to help them get around in a city that prides itself on walking and more walking.
