This week we discuss isokinetic testing for shoulder internal and external rotation strength! This scoping review had a lot of promise, but unfortunately it did not live up to the hype for us. We learned there is a lot of heterogenity in testing set ups, but the seated 90/90 position is the most common, with 60 and 180 degrees per second being the most common speeds tested. The most common objective measures from these tests are peak torque and ER:IR ratio, but there are a lot of variations of ER:IR ratio looking at differences in concentric and eccentric force outputs. The information we wished this article gave was the average values for peak torque and ER:IR ratio from each of the studies so clinicians would be able to have a general idea of benchmark scores their patients should be hitting. We feel this is a big missed opportunity which could have made this paper a 10/10!
