On October 4-5th 2019, sports physiotherapists from all over the world gathered for the 3rd World Congress of Sports Physiotherapists (https://www.sportphysio.ca/calendar-of-upcoming-events/spc2019/). A major topic of discussion was the value of screening (ROM, strength, functional tests…) for injury prevention and return to play after injury. The world experts agree that at this moment, there is not enough evidence to claim that we may predict (re)-injury performing screening tests, but that does not mean that screening is useless (Bahr 2016) . The goal of screening is to identify existing problems, have baseline measures for future follow up, create a database of “normal” values within the specific population of athletes you work with, and to assess the capacity (physical performance) of the athlete when returning to play compared to his/her fellow athletes (Ardern et al. 2016).
For the upper limb, reliable tests are available for ROM, strength, and upper limb performance (like the Seated Medicine Ball Throw (SMBT), the Y-balance test Upper Quadrant (YBT-UQ) or the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST), however the validity is unclear (Cools et al. 2014, Borms et al. 2016) . As an example, the SMBT highly correlates with shoulder and elbow strength, and is a valuable alternative for strength testing “on the field”, however the YBT-UQ does not correlate with strength. So we don’t know (yet) what we test with the YBT-UQ, but definitely not strength only (Borms et al. 2016).
Criteria for RTP criteria may be found in 3 categories of research papers: 1/ studies analyzing risk factors for shoulder pain in different shoulder loading sports (Asker et al. 2018), 2/ descriptive analyses of ROM, strength and functional performance in elite athletes (Cools et al. 2014, Vanderstukken et al. 2019), and 3/ references values from larger populations (not always elite) (Cools et al. 2016, Borms et al. 2018). The future of screening lies in developing a test-battery rather than individual tests, in order to assess as many aspects of shoulder performance as possible (Olds et al. 2019).
