MATERIALS AND METHODS: Adults mechanically ventilated ≥48h and anticipated to remain in ICU≥5days were included. Physical activity (PA) was measured using a SWA-MF (over the first five days); energy expenditure was measured with both the SWA-MF and the Deltatrac II metabolic cart on day three; highest level of mobility was assessed on the IMS. RESULTS: Fifty-five participants performed median [IQR] 16.8 [0.6-152.4] minutes of PA per day (defined as >1.0 metabolic equivalent). A strong correlation between active energy expenditure and highest level of mobility (IMS), r=0.76, p=0.00 was observed on day 5. The SWA-MF demonstrated moderate to good agreement with the Deltatrac II metabolic cart (n=20), intra-class correlation co-efficient=0.71 (p=0.00) for the measurement of energy expenditure on day 3. CONCLUSIONS: Participants demonstrated low levels of PA. Motion sensors may be a promising non-invasive measure of energy expenditure and further investigation is warranted. | URI: | https://ahro.austin.org.au/austinjspui/handle/1/16647 | DOI: | 10.1016/j.jcrc.2017.04.006 | Journal: | Journal of Critical Care | PubMed URL: | https://pubmed.ncbi.nlm.nih.gov/28431343 | Type: | Journal Article | Subjects: | Critical care Functional outcomes Mobilisation Physical activity Physical therapy Rehabilitation |
