View Full Version : Trip and fall into a depression in walking surface

01-26-2010, 02:28 AM
Has anybody done research into this subject or read any studies related to it?

My experience in investigating such accidents is that, when the depth of the depression is less than an inch, people are usually able to recover. If the depth of the depression is between an inch and three inches, some are able to recover, while others will fall forward or stumble a few steps forward and then either fall or recover. When the depression is more than 3 inches deep, few individuals are able to recover without falling, and what typically occurs is that one of their legs folds under them and they fall onto that foot, resulting in a hyper-extension of that knee.

I am looking for information that might confirm, disprove or revise these hypotheses.
