“…Twenty-two studies [ 25 , 29 , 31 , 32 , 33 , 34 , 35 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ] accounted for SD. Tenderness, asymmetry, restricted motion, and tissue texture (TART criteria) were used to identify SD in 17 of the 22 studies [ 25 , 29 , 31 , 32 , 33 , 34 , 35 , 39 , 41 , 42 , 43 , 44 , 46 , 47 , 49 , 51 , 52 ]. In 4 of the 22 studies [ 38 , 40 , 42 , 53 ], the SD was considered a region rather than a specific structure ( Figure 2 ).…”
