However, this approach has proven ineffective in a subgroup of females who have suffered from PFP for multiple years.\n\nThis group was found to have a significantly lower tolerance for pressure stimuli compared to healthy controls. This indicating that central mechanisms within the nervous system rather than the problem being the knee itself.\n\nExercising a non-painful muscle distant to a painful part of the body has previously been effective in deceasing pain in affected area. This mechanism has been investigated in patients with long-standing musculoskeletal pain as well as healthy populations.\n\nRelated research has suggested that a possible link between patients perception of painful stimuli an the pain-reducing effect of exercise exists. As such, patients witch experienced a pain reducing effect of exercise was found to be able to tolerate more pain than before the intervention.\n\nThe aim of this study is to assess if exercising a distant non-painful muscle around the hip has a larger acute pain-reducing effect on knee pain compared to knee specific exercises in female patients with long-standing PFP.",[66],"Patellofemoral Pain Syndrome",[68,69,70],"Patellofemoral pain","PFP","PFPS","COMPLETED","2017-06-09",{"date":74,"type":60},"2017-06-12",{"date":76,"type":60},"2017-03-07",{"date":78,"type":60},"2017-06-01",{"name":5,"class":6},1]
