In fact, the overwhelming majority are considered nothing more than "incidental" MRI findings since such pathology may be noted in as many as 80% of otherwise asymptomatic patients!
To that end, I could envision patients of this type being utilized as a "PEP treatment group" of sorts, as a means of proving PEPs are an effective form of therapy.
Of course since effectively all comers with this sort of pathology improve over time with "conservative care", the efficacy of "PEP therapy" would be very unlikely to exceed that of placebo!
