HRIG

The Future of Hamstring Assessment. Evidence-Based. Athlete-Proven.

Developed over 7+ years in collaboration with leading sports medicine institutions, the HRIG (Hamstring Re-Injury Indicator Generator) from SISM represents a breakthrough in objective hamstring strength assessment and injury prevention.

This innovative system is the result of deep clinical research and real-world testing across more than 2,000 athletes, with input from teams at the Sports Injuries and Sports Medicine Clinic (Ireland), Connacht GAA Centre of Excellence, Liverpool John Moores University, and Sheffield Hallam University.

Now available in the UK & Ireland through Kikko Health, HRIG enables precise isometric testing, bilateral comparisons, and strength profiling to help performance teams, physiotherapists, and rehab specialists reduce injury risk and support confident return-to-play decisions.

Whether you’re managing elite-level return-to-sport protocols or building long-term athlete development pathways, HRIG delivers unmatched data clarity — in a portable, practitioner-ready format.
