“…Prolonged standing pain developers (PDs) have shown many common characteristics with patients suffering from LBP 15 , 21 , 24 , 29 , 33 , 36 , 37 , 42 , 46 , 50 , 51 , 55 , 62 . In other words, they have been compared either directly to patients with “non-specific” 62 , chronic 36 , and recurrent LBP 16 , or indirectly to non-pain developers (NPDs) based on distinctive characteristics previously reported for patients with LBP in the literature. PDs have displayed altered muscle activation 9 , 14 , 24 , 32 , 33 , 39 , 41 , 44 , alignment 20 , 26 , 35 , 51 , 56 , and movement patterns 13 , 20 , 29 , 35 , 37 , 45 , 47 , 50 , 52 , 56 that make them susceptible to LBP based on kinesiopathologic model of LBP 63 .…”
