It is very possible that tissue provocation therapies like Graston are actually exacerbating/increasing pain.
Article published in the Toronto Star entitled “The death of the sit up”. Based on the work of Stuart McGill of the University of Waterloo, a back biomechanics and injury researcher, the Canadian Armed Forces have dropped the sit-up from their fitness testing protocols, which has garnered the attention of the US Army.
I like McGill’s viewpoint on the relatively poor value of sit-ups in terms of promoting all-around health. He states that while perhaps a useful exercise for the jujitsu athlete (which is true), the sit-up is not conducive, nor is it at all necessary, for all-around health promotion.
