Fig. 1.

Ranges of motion for flexion/extension, (FLEX/EXT) abduction/adduction (ABD/ADD) and internal/external (IR/ER) rotation for each performed test and hip position with each graph representing the testing in different hip flexion–extension positions, and each different colour bar representing the different soft tissue states (I intact, II after removal of skin and muscles, while leaving the capsuloligamentous structures intact, and III after partial circumferential capsulectomy). Figure 1 represents the ROM in each plane with the hip in a 90 degrees of flexion, b in full flexion, c in neutral flexion–extension and d in hyperextension of the hip
