PURPOSE: To investigate the validity and reliability of the Activity Monitoring Pod (AMP331) to record gait parameters in healthy young adults (YA) and intensive care unit inpatients (ICU). METHODS: Fifteen YA completed a series of over-ground walks. Another 15 YA completed a series of treadmill walks. The ICU group (N=20) completed a series of over-ground walks with repeat trials. Gait parameters were recorded simultaneously for each walk. RESULTS: For the YA over-ground condition, no significant differences were found between the measures recorded by the systems. For the YA treadmill condition, 43% of the measures differed (P < .05). For the ICU group, the AMP331 underestimated distance a..View full abstract
