PURPOSE To critically evaluate the current standard for manually assessing strength both clinically and in the scientific literature: the 0-to-5 scale that evolved from the post-World War II report of the British Medical Research Council. Although widely used by surgeons and researchers, no physical analysis of its validity is available. With the elbow used as an example, a static physics experiment is devised to quantify the enormous difference between maximum strength (grade 5/5) and the… CONTINUE READING
