OBJECTIVES: To measure and calculate the energy expended by people with stroke
during near sedentary behaviors (lying, supported and unsupported sitting,
standing, wheelchair propulsion, walking), under controlled laboratory
conditions, and to compare these values with the energy expenditure of 1.5
metabolic equivalent task (MET) within the definition of sedentary behavior.
DESIGN: Cross-sectional cohort study. SETTING:
Rehabilitation institutions.
PARTICIPANTS: People with stroke (N=27; mean age, 61.0+/-11.7y), categorized at
Functional Ambulation Categories (FAC) 0 to 5. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Energy expenditure (measured using indirect calorimetry)
expressed in METs. The recorded values were calculated for every participant and
averaged for each activity: lying, supported and unsupported sitting, standing,
wheelchair propulsion, and walking. Calculations were done for the total group
and categorized by the FAC. RESULTS: For the total group the mean METs +/- SDs
were 1.04+/-.11 for sitting supported, 1.09+/-.15 for sitting unsupported,
1.31+/-.25 for standing, 1.91+/-.42 for wheelchair propulsion, and 2.52+/-.55 for
walking. People with stroke in all FAC had METs values >1.5 when propelling a
wheelchair or walking. CONCLUSIONS: Energy expenditure during typical sedentary
behaviors (ie, sitting) is narrowly bounded at approximately 1.0 MET. Energy
expenditure during sitting and standing was </=1.5 MET for all FAC, with the
exception of FAC 0 (1.6 MET during standing). Independent wheelchair propulsion
and walking can be categorized as light activities (>/=1.5 MET).
