Evaluation and optimisation of physical activity in individuals with chronic obstructive pulmonary disease (COPD)

The studies in this thesis evaluated the physical activity (PA) in individuals with chronic obstructive pulmonary disease (COPD), identified strategies to optimise PA, determined the effects of a supervised walking training program on performance during the endurance shuttle walk test (ESWT) and determined the minimal detectable difference for the ESWT.The measurement techniques used included: PA using motion sensors; HRQoL assessment; Fear of Falling Questionnaire, Hospital Anxiety and Depression Scale; and functional exercise testing

Accuracy and Responsiveness of the stepwatch activity monitor and ActivPAL in patients with CODP when walking with and without a rollator

Purpose: To evaluate the measurement properties of the StepWatch™ Activity Monitor (SAM) and ActivPAL in COPD. Method: Whilst wearing both monitors, participants performed walking tasks at two self-selected speeds, with and without a rollator. Steps obtained using the monitors were compared with that measured by direct observation. Results: Twenty participants aged 73 ± 9 years (FEV1 = 35 ± 13% pred; 8 males) completed the study. Average speeds for the slow and normal walking tasks were 34 ± 7 m•min−1and 46 ± 10 m•min−1, respectively. Agreement between steps recorded by the SAM with steps counted was similar irrespective of speed or rollator use (p = 0.63) with a mean difference and limit of agreement (LOA) of 2 steps•min−1 and 6 steps•min−1, respectively. Agreement for the ActivPAL was worse at slow speeds (mean difference 7 steps•min−1; LOA 10 steps•min−1) compared with normal speeds (mean difference 4 steps•min−1; LOA 5 steps•min−1) (p = 0.03), but was unaffected by rollator use. The change in step rate between slow and normal walking via direct observation was 12 ± 7 steps•min−1 which was similar to that detected by the SAM (12 ± 6 steps•min−1) and ActivPAL (14 ± 7 steps•min−1). Conclusions: The SAM can be used to detect steps in people who walk very slowly including those who use a rollator. Both devices were sensitive to small changes
