AB RationaleDuring a hospital admission for an acute COPD exacerbation, physical activity (PA) is low and does not completely recover after discharge. As physical inactivity has been associated with impaired prognosis, PA promoting strategies may become important as an intervention immediately after hospital discharge.Methods26 patients were randomly assigned to an intervention group (N=14), coached towards higher PA or a control group (N=12) receiving usual care. Patients in the intervention group wore the Fitbit Ultra®, an accelerometer providing real time information on PA, around the ankle during one month. PA was discussed with a dedicated physiotherapist by means of 3 weekly telephone contacts (12 in total).ResultsDespite randomization, patients in the intervention group had a significantly lower FEV1 (31±8 vs 45±10% (p<0.001)), muscle strength (77±36 vs 118±24 Nm (p=0.003)), exercise capacity (200±97 vs 336±87 meter (p=0.002)) and PA (512±170 vs 1559±385 steps (p=0.02)) at baseline in comparison to their controls. Figure 1 demonstrates that PA is improving after discharge with no effect of the PA promoting strategy (PAsteps: p=0.86; PAwalking: p=0.91)ConclusionPilot data suggest that PA recovers after an acute exacerbation to levels determined by the baseline condition. Contrary to our expectations, physical activity coaching in the month after hospital discharge does not result in higher levels of PA.
