A prospective study on physical activity levels after spinal cord injury during inpatient rehabilitation and the year after discharge.
OBJECTIVE
To assess the change over time in the physical activity level after a spinal cord injury (SCI), to explore its determinants, and to compare the physical activity level 1 year after discharge from the rehabilitation center with the level in able-bodied persons.


METHODS
Prospective cohort study. Measurements were obtained at the start of active rehabilitation, 3 months later, at discharge, 2 months after discharge, and 1 year after discharge.


METHODS
Rehabilitation center in The Netherlands and the participant's home.


METHODS
Persons (n=40) with SCI.


METHODS
Not applicable.


METHODS
The physical activity level, as indicated by the duration of dynamic activities (ie, wheelchair driving, walking, cycling, noncyclic movement) per day, and the intensity of everyday activity; both were measured with an accelerometry-based activity monitor during 2 consecutive weekdays.


RESULTS
Random coefficient analyses showed that the duration of dynamic activities and the intensity of everyday activity increased during inpatient rehabilitation at rates of 41% and 19%, respectively (P<.01). Shortly after discharge, there was a strong decline (33%; P<.001) in the duration of dynamic activities. One year after discharge, this decline was restored to the discharge level but was low in comparison with levels in able-bodied persons. The level of lesion and completeness of lesion were determinants of the change in the physical activity level after discharge.


CONCLUSIONS
The physical activity level increased during inpatient rehabilitation, but this increase did not continue after discharge, and the level 1 year after discharge was distinctly lower than the level in able-bodied persons. Subpopulations had a different change over time in the physical activity level after discharge.
