Lean mass and BMD were assessed at 2 weeks, 1, 3 and 6 months post-stroke using DXA. Physical activity levels were monitored using an accelerometer with positional changes and lying, sitting, standing and walking times recorded.
The greatest bone loss was observed in cortical bone of the paretic leg. Higher motor control and walking ability was associated with less bone loss. Less change in bone turnover was associated with number of times subjects stood up but not the total time standing at baseline.
