Effect of Star Excursion Balance Test on Balance, Quality of Life and Functional Status in Patients With Patellofemoral Pain Syndrome

Patellofemoral pain syndrome (PFPS) is a common and painful musculoskeletal condition that affects physically active young adults and causes pain front of the knee. Patients with PFPS has bilateral impairment in proprioception, as well as more in the affected knee than the normal; also the decrease of muscular strength, range of motion, and neuromuscular control are known to result with impaired static and dynamic balance. We aimed to investigate the efficacy of a-four week YDT balance exercises on pain, quality of life and functional state in patients with PFPS with impaired balance.

Patients with PFPS diagnosed will included in the study. Participants will randomized into the YDT exercise group (n = 24), the KAT 2000 exercise group (n = 24) and the combined exercise group (n = 24). Before the study, all groups of patients will given exercises such as quadriceps, vastus medialis oblique (VMO), hip abductor, extensor and external rotator strengthening exercises. All patient groups received balance training for four weeks, three days a week.

Pain intensity will be measure on Visual Analog Scale (VAS). Functional capacity will be evaluated by using the Western Ontario McMaster Osteoarthritis Index (WOMAC) and Kujala Patellofemoral Score (KPS). Static balance performance will be evaluated by using Kinesthetic Ability Trainer 2000 (KAT 2000) and dynamic balance performance will be evaluated by using Berg Balance Scale (BBS) and KAT 2000. The quality of life will assessed using Nottingham Health Profile (NHP).
