The use of the Actiwatch to assess movement in people with profound intellectual and multiple disabilities

Research output: Contribution to conferenceAbstractAcademic


Introduction: People with profound intellectual and multiple disabilities (PIMD) are heavily dependent on support to perform movements. Currently, assessment of movement in people with PIMD involves the use of diaries and heart rate monitors, unable to assess the actual amount of movement of people with PIMD. The purpose of the present study was to investigate the psychometric properties of the Actiwatch to objectively assess movement in people with PIMD.
Methods: Twenty-two persons with PIMD were video recorded for about 6 hours divided in 15-min periods and worn an Actiwatch for at least seven consecutive days. The overlapping period of registration was used for analysis. We used instantaneous sampling per 15 s to record the occurrence of movement, body position, and activity situation. Multilevel analysis were used to analyse the outcomes of the Actiwatch among different (activity) situations and body positions.
Results: Early results, based on basic statistics, show a significant difference in outcomes of the Actiwatch between performed and no performed movements, comparable outcomes for different body postures and a significant effect of one of the activity situations. The final results will be presented at the congress. Implications: This study will demonstrate if the Actiwatch can be used to objectively assess movements of people with PIMD during different activities and performed from different body postures.
