Is measurement error altered by participation in a physical activity intervention?
Measurement error of self-report relative to the accelerometer appeared to be affected by intervention. Because measurement error cannot be definitively attributed to self-report or accelerometer, it would be prudent to measure both in future studies.
Asymptomatic embolization in carotid stenosis predicts short-term ipsilateral stroke risk. This supports use of the technique to identify patients at high-risk for recurrent stroke for therapeutic interventions and as a surrogate marker to evaluate antithrombotic medication.
