Abstract
A case history of a non-irritable knee joint dysfunction is presented to illustrate the importance of recognizing specific end-of-range positions (e.o.r.ps.). E.o.r.ps. are defined as the extremes of functional movement patterns tested passively. This case history is intended to demonstrate the value of recognizing these positions as far as effectiveness of treatment is concerned. No attempt is made here to describe the e.o.r.ps of joints other than the knee. Knowing exactly how to test joints in cases of pain with apparent full range of movement and knowing how to treat the patient when range of movement is lost enhances both effectiveness and efficiency of diagnosis and treatment.
