5. Study Description

Brief Summary
The purpose of this study is: To examine the effect of infra patellar strap treatment on the extent of pain and jumping performance tasks in young male athletes diagnosed with patellar tendinopathy. 40 elite male athletes, basketball and volleyball players, ages 14-18, students of the academy for sports Excellency will take part in this study Hypothesis 1: The treatment of infra patellar strap will reduce the level of pain during jumping performance tasks. Hypothesis 2: The treatment of infra patellar strap will improve the squat jump height in athletes with patellar tendinopathy during squat jump task. Hypothesis 3: The treatment of infra patellar strap will improve the drop jump height in athletes with patellar tendinopathy during drop jump task. Hypothesis 4: The treatment of infra patellar strap will improve the one leg jump height in athletes with patellar tendinopathy during one leg jump task. Hypothesis 5: The treatment of infra patellar strap will improve the 30 seconds repetitive jumps mean height in athletes with patellar tendinopathy during 30 seconds repetitive jumps task.
Detailed Description
Introduction: Patellar tendinopathy (Jumper's knee) is a condition usually characterized by localized pain and tenderness of the patellar tendon at its origin on the inferior pole of the patella. Patellar tendinopathy is an over use injury which implies on a mismatch between stress on a given tissue and the ability of that tissue to withstand the stress. Rapid repetitive actions of acceleration, deceleration, jumping and landing place great stress on the extensor mechanism and the patellar tendon. Current prevalence reported of patellar tendinopathy is up to 20% among elite athletes from a range of sports, with higher proportions in professional basketball (32%) and volleyball (45%) players. The common treatment for patellar tendinopathy is preventative or conservative (physical therapy). Infra patellar straps are used in treatment to reduce anterior knee pain from a variety of sources including patellar tendinopathy, patellar subluxation, patellar femoral syndrome, Osgood-Schlatter disease and more. In spite of the frequent use of this strap in young athletes and the subjective report of decreased anterior knee pain experienced by the athletes using them, the mechanisms for reducing anterior knee pain has not been explained. In addition, there is no data on the straps effect regarding the extent of pain and functional performance as jumping in this population. The purpose of this study: To examine the effect of infra patellar strap treatment on the extent of pain and jumping performance tasks in young male athletes diagnosed with patellar tendinopathy. Methods: 20 elite male athletes, basketball and volleyball players, ages 14-18, students of the academy for sports Excellency will take part in this study. Athletes approaching the physical therapy department of the Ribstein Center for Sport Medicine Sciences and Research at Wingate Institute, with anterior knee pain, will be examined by a professional physical therapist. The ones who are diagnosed with chronic patellar tendinopathy will be included in the study. Each athlete will attend one meeting in which he will perform four tests: Squat jump test, Drop jump test, one leg jump test and jumps 30 seconds test. The tests with and without the infra patellar strap will be performed using The Optojump measuring system (Microgate, Bolzano, Italy). In addition the athlete will grade his pain severity with and without the infra patellar strap, using The Visual Analog Scale (VAS).There will be no follow up, all the data will be collected in one session. Data will be collected between january 2012 and december 2012, data analysis and summary of the study will be finished at december 2013. Statistical Analysis: In order to examine the difference between the tests results with and without the infra patellar strap, dependent t- test will be performed. Significant level will be set at P<0.05.
