How consistent are physiotherapists in the advice they give to knee osteoarthritis patients? It could be better, it seems. The important message from the linked paper's abstract:
Quality indicator compliance less than 50% was found for: education on the importance of weight loss, providing self-management strategies, spreading treatment session over longer periods and regular evaluations of the exercise therapy.
Less than 50% give advice for weight loss! Shouldn't that be one of the first things one would say, given how many people in Belgium, where this study was conducted, are overweight?
