Mean sources were defined as the maximum t-value, and a sphere of 2 cm surrounding it, and distinct sources could not be overlapping. Displayed for means sources are location, peak t-value and mean t-value within the source. Individual sources were found within the volume of significant t-values. For each subject, the maximum power difference between normal walking and sitting conditions within this significant volume was determined.
