Physical Activity Measure Application

Measure, from postoperative Day 1 up to Day 4 of time spent sitting/lying-down

Measure, from postoperative Day 1 up to Day 4 of number of sit-to-stand transitions

Measure, from postoperative Day 1 up to Day 4 of number of number of steps

Measure, from postoperative Day 1 up to Day 4 of number of walking cadence

Measure, from postoperative Day 1 up to Day 4 of time spent sitting/lying-down using ACTIM application

Measure, from postoperative Day 1 up to Day 4 of number of sitting-standing transition using ACTIM application.

Measure, from postoperative Day 1 up to Day 4 of step count using ACTIM application.

Measure, from postoperative Day 1 up to Day 4 of walking pace using ACTIM application.

Measure of indicators of physical activity volume :

Number of counts/day (Sum of counts (vertical axis) accumulated over the day) Number of steps/day (Sum of steps accumulated over the day)

Measure of indicators of physical activity intensity :

Average number of counts/minute, Average walking pace (Average number of steps/minute).

Measure of Indicators of duration :

Sedentary time (Total minutes/day < 100 counts/minute), Light-intensity physical activity (Total minutes/day between 100 and 1,951 counts/minute), Moderate-intensity physical activity (Total minutes/day between 1,952 and 5,724 counts/minute), High-intensity physical activity (Total minutes/day ≥ 5,725 counts/minute), Moderate/high-intensity physical activity (Total minutes/day ≥ 1,952 counts/minute).

Measure of indicators of duration of walking at each intensity :

Occasional movement (Number of minutes with 1 to 19 steps/minute), Sporadic movement (Number of minutes with 20 to 39 steps/minute), Intentional walking (Number of minutes with 40 to 59 steps/minute), Slow walking (Number of minutes with 60 to 79 steps/minute), Moderate walking (Number of minutes with 80 to 99 steps/minute), Brisk walking (Number of minutes with 100 to 119 steps/minute), Fast walking (Number of minutes with ≥ 120 steps/minute),

Measure of indicators of energy expenditure : physical activity-related energy expenditure estimated by a prediction equation

Measure of indicators of moderate to high-intensity physical activity :

Number of sessions/day (Number of sessions (≥ 1 min) ≥ 1,952 counts/minute), Average session duration (Average session duration ≥ 1,952 counts/minute), Number of sessions ≥ 10 min (Number of sessions (≥ 10 min) ≥ 1,952 counts/minute), Total duration in sessions ≥ 10 min (Total duration of physical activity in sessions ≥ 10 min).

Measure of indicators of sedentary :

Number of sessions/day (Session number (≥ 1 min) < 100 counts/minute), Average session duration (Average duration of sessions < 100 counts/minute), Number of sessions ≥ 10 min (Session number (≥ 10 min) < 100 counts/minute), Total duration in sessions ≥ 10 min (Total duration of sedentary behavior in sessions ≥ 10 min),

The level of satisfaction/feasibility with the ACTIM application will be assessed using a satisfaction scale from 0 to 10 (0: Not satisfactory and 10: Very satisfactory) when the device will be remove.

Using an interest scale from 0 to 10 (0: Not interesting to 10: Very interesting). The format in which this information is made available will be evaluated using a satisfaction scale (0: Not satisfactory to 10: Very satisfactory) when the device will be remove.

Postoperative complications will be recorded using the 'Morbidity and Mortality after Thoracic Surgery' classification from hospital discharge up to 1 month post surgery

Patients' acceptability of wearing the ActiGraph GT3X will be assessed when the equipment is removed, using a simple numerical scale ranging from 0 : unbearable to wear to 10 : no discomfort.
