Fig 1. Examples of statokinesigrams from faller and non faller individuals, during the open eyes part of the experiment.

Interestingly, fallers and non fallers do not always have visually distinctive statokinesigrams. A tight faller statokinesigram in a) seems pretty close to the non-faller’s statokinesigram in b). Similarly, a wider non-faller’s statokinesigram in c) seems close to a faller’s statokinesigram in d). In those examples, simple indices alone such as velocity of sway area or acceleration alone would probably fail to discriminate fallers from non fallers.
