Objective: A comparison between standard elastic bandage and taping on postural control in athletes with patellofemoral pain.
Design of study: 38 persons (men & women) that have anterior knee pain participate in this study.
Inclusion criteria consist of: volunteers have history of regular sport activity; they have anterior knee pain or retro-patellar pain at least as long as 1 month; pain suffering during step up and step down, squat, running and jumping activity; palpating of facet joints producing pain; at least one of three tests consisting: apprehension, step down eccentric and vastus medialis coordination should be positive.
Exclusion criteria: symptoms initiating less than 1 month ago; symptoms are related with direct trauma; ligamentus laxity and/or other injury such as ACL injury at the tested leg; surgery at tested knee in latest 3 month.
Interventions: volunteers divide in two groups, the first group is taped and second group is wrapped with elastic bandage. Postural control capability at both groups is measured before and after interventions by force- platform and star excursion balance test.
Primary outcome measures: COP displacement measures at anterior- posterior and medial- lateral direction before and after taping or wrapping, COP velocity measures at anterior-posterior and medial-lateral directions, reach direction measures at anterior, antero- medial, antero- lateral, medial, lateral, posterior, postero- lateral, postero- medial by used of SEBT before and after taping and bandage.
Secondary outcome measures: COM displacement measures at anterior-posterior & medio- lateral directions.
