Because weightlifters who have a history LBP and of being able to lift large amounts of weight without pain after LBP resolution DOES NOT prove or disprove anything! Lifting WITH pain is not an inclusionary criteria for diagnosing TA and M dysfunction. The population in the study "Multifidus recovery in not automatic after resolution of LBP" all had symptom resolution but still had dysfunctional TA and M. This does not mean that they experienced LBP EVERYTIME they did something functional. But that DOES NOT mean that they were not experiencing excessive shear forces which were below sensory threshold. There very well may be some compensatory mechanisms that we do not know about yet, but again, that does not invalidate what we do already know about TA and M.
