A treadmill pulling you … for science / Boing Boing



As part of the research on how to make better prostheses, Vanderbilt University placed engineers on a treadmill and made them stumble. Repeatedly. By better understanding people's stumbling reflexes, they hope to improve the computerized stumble response in the prosthesis. But to learn how people catch themselves, they had to raise them first. And it required building a stumbling unit in a treadmill. From Vanderbilt University:

Andrés Martínez quickly jumped on the treadmill and stared straight ahead and counted back with seven from 898, a trick to keep his brain from anticipating the literal ostrich phase on the road: a compact 35 pound steel specially designed to make him fall.

Special goggles kept him from looking down. Arrows on an eye-level screen prevented him from moving away from the sides. A harness attached to a beam of beam kept him safe. Sure enough, when a computer program released the steel block, it slipped on the treadmill, and Vanderbilt University's PhD students struggled to stay on the foot …

"Not only does our treadmill need to raise them, it has to raise them at certain points in their course," said Shane King, a graduate student and lead author on paper. "People stumble differently depending on when their foot hits a barrier. The device also had to overcome their fears of falling so they couldn't see or feel when the block came."
