Background & Study Aim: On the battlefield in ancient Japan, there were no referees to say “Stop!” to cease combat. If warriors (samurai) sustained an injury on the battlefield, they would have to keep fighting, so they had to seriously think of ways that would allow them to fight even in instances in which they have lost function of a upper limb or are forced to fight from a sitting position (due to lower limb injury or loss). Therefore, we could say that budo (Japanese martial arts) has had an open system for the disabled since the very beginning, and anyone can practice budo today. The aim of this study is a new proposal on how to assess karate competitors with disabilities, which might replace the current 3-grade point system used by the World Karate Federation.
Materials & Methods: A functional assessment (21-grade point adding system) based on range of motion and speed of technique was developed that analyzes video of competitors with Kinovea software.
Results: The results show that the margins of error are too high for a reliable functional assessment of the 21-grade point adding system. However, video analysis of movements is bringing considerably more data about competitor performance than traditional methods of observation.
Conclusions: The proposed functional assessment through video analysis may give karate referees better insight than the current mandatory system. This is therefore bringing us closer to fairer regulations that cannot otherwise be reached.
