In the recent article published in the BJSM, professor Ekstrand and his colleagues have evaluated the Munich consensus on muscle injury classification. They conclude the study with the words that even though the Munich muscle classification demonstrates a positive prognostic validity for the return to play after a thigh muscle injury in professional male football players, there are still many opportunities for improvement, especially in the field of functional muscle disorders. Unlike with the structural muscle disorders, functional disorders cannot be diagnosed and monitored with an MRI or other widely used methods. They do not provide useful information in later stages when the muscle structure recovers, yet the muscle function stays impaired. Only methods such as tensiomyography evaluate muscle function. With the implementation of such methods, functional muscle disorders can be detected and treated in an efficient manner, which leads to a faster RTP and lower re-injury rates.
