Design outcomes

Primary

MeasureTime frame
Rate of dynamic hyperinflation (&#916;IC/s): Hyperinflation is defined as an increase in the end-expiratory lungvolume (EELV). A decrease in inspiratory capacity (IC) is used as a substitute for the increased EELV. This is based on the assumption that the total lungcapacity (TLC) has to remain constant. An increase of the EELV has to result in a decrease of the IC, because the sum of these parameters composes the TLC (EELV+IC=TLC).

Secondary

MeasureTime frame
1. Rate of recovery after DH (&#916;IC/s); 2. The degree of DH (&#916;IC); 3. Activity outcome IMA. To measure physical activity a smartphone (HTC Desire/ HTC Desire S) and a motion sensor (ProMove 3D wireless inertial sensor, Inertia Technology) will be used. The motion sensor is a triaxial accelerometer that measures acceleration. The average value of the three axes of motion are than calculated and converted into activity outcome IMA. The outcome measure is calculated with the method of Bouten et al., that can be highly related to energy expenditure. A change of velocity occurs when a person starts to move and stops to move. The motion sensor connects through a Bluetooth-connection with a smartphone. Daily activity data is subsequently memorized as activity outcome IMA on the hard drive of the smartphone. The motion sensor is being carried on the patient’s belt and the smartphone is being kept near the patient. This method has been approved by the Medical research ethics committee of the Medisch Spectrum Twente Hospital in Enschede. 4. Borgscale (1-10) before and after MPT.
