Purpose
Although increased effort has been put into studies connecting disability with physical activity, problems remain regarding current disability instrumentation. The purpose of this article is to discuss the crucial need to improve two areas of research that are of utmost importance: the lack of operational clarity and the limited precision of the equipment to detect any changes in response to physical activity interventions.
