“…7 Yet at present, there are no clear PA guidelines for individuals with SCI, 8 partly through lack of consensus about activity assessment and EE measurement in this wheelchair-dependent population. 2 A range of techniques have been previously employed under both community-dwelling and laboratory conditions, including indirect calorimetry, 9 heart rate (HR) monitoring 4,10,11 and PA recall questionnaires such as…”

“…8 However, due to limitations with some of the techniques for this population, and the lack of comparative studies between the various techniques, there is insufficient evidence to determine which method most accurately estimates TDEE or PAEE in wheelchair users with SCI. For example, despite some initial research to assess EE after SCI, including HR monitoring 4,11 and PA recall questionnaires, 8,12 these methods have not been validated against a reference standard such as the doubly labelled water (DLW) technique. Additionally, the SenseWear Armband (SWA), which has been used to estimate EE in overweight children, 13 in patients with cancer, 14 and healthy children, 15 has not been validated in SCI population.…”

Objective: To compare different methods of assessing energy expenditure (EE) and physical activity (PA) in people with spinal cord injury (SCI) under community-dwelling conditions. Methods: A reference standard encompassing the doubly labelled water (DLW) technique, heart rate monitoring (FLEX-HR), a multi-sensor armband (SenseWear Armband (SWA)), and two PA recall questionnaires were employed in 14 people with SCI to estimate EE and leisure-time PA. Results: Mean total daily energy expenditure (TDEE) assessed by DLW, FLEX-HR, and SWA were 9817 ± 2491 kJ/day, 8498 ± 1516 kJ/day, and 11414 ± 3242 kJ/day, respectively. Physical activity energy expenditure (PAEE) quantified by DLW was 2841 ± 1626 kJ/day, 2935 ± 1732 kJ/day estimated from FLEX-HR, and 2773 ± 2966 kJ/day derived from SWA. After converting the PA recall questionnaire data to EE in kJ/day, PAEE for the Physical Activity Recall Assessment for People with Spinal Cord Injury (PARA-SCI) was 2339 ± 1171 kJ/day and for Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) 749 ± 1026 kJ/day. DLW-quantified PAEE was moderately associated with PARA-SCI (R 2 = 0.62, P < 0.05), but not with the other estimates of PAEE (R 2 ranged between 0.13 and 0.30, P > 0.05). Conclusion: Our findings revealed that the PARA-SCI recall questionnaire was the best estimate of PAEE compared to the reference standard DLW approach. Although the between-method variability for SWA, FLEX-HR, and PASIPD-derived PAEE was small, there was a weak association between these methods and the criterion DLW technique. The best estimate of DLW-quantified TDEE was by FLEX-HR. SWA significantly overestimated TDEE in this population.
