307 THE FEASIBILITY OF USING AN INCLINOMETER TO PROVIDE OLDER HOSPITALISED PATIENTS WITH FEEDBACK ON THEIR ACTIVITY LEVELS

Abstract

Abstract Background Low levels of physical activity in older adults are well documented and have been associated with functional decline, acute sarcopenia, prolonged length of stay and higher readmission rates. Interventions to modify behaviour in hospitalised older adults include providing feedback on performance. Commercially available activity trackers and pedometers which rely on step count, are often unable to detect steps at the walking speeds found in older hospitalised patients. This study investigated the feasibility of using an inclinometer to measure the time spent by older hospitalised adults in lying and sitting versus standing and walking, and to provide feedback to patients on their active versus sedentary levels. Methods This was a feasibility study using a cross-sectional single centre design. Twelve inpatients over 70 years of age were fitted with an ActivPAL accelerometer on their thigh, which was worn continuously for 3 days. A graphic display of sedentary versus active time was provided to the participants each morning. Acceptability of wearing the device and receiving feedback was determined using a modified technology acceptance questionnaire. Results Twelve hospitalised older adults (7 female, 5 male) were included in the study, median age 74 (66-84). A modified technology questionnaire showed that 83% of participants found the ActivPAL device comfortable to wear, 100% reported that the feedback from the device was clear and understandable and 92% reported that the information enhanced their motivation for physical activity and that they would wear the device again. Conclusion This feasibility study shows that the ActivPAL is a device that can be worn in the hospital setting to provide older adults with feedback on their activity levels in order to modify behaviour and increase their levels of physical activity while in hospital.
