Effectiveness of Bosu Ball and Agility Training in Enhancing Dynamic Balance and Speed in Post - Operative Jumper?s Knee among Basketball Players

Background: Jumper's knee is the most frequent injuries in sports and it has upset many professional sporting careers. The term "jumper's knee" was first introduced by Blazina, a gradual insidious onset of aching in the knee centered over the infrapatellar or suprapatellar region, especially localized to the superior or inferior poles of the patella. Patellar tendinopathy is primarily a condition of relatively young (15 -30 years old) athletes, especially men, who participate in sports such as basketball, volleyball, athletic jump events, tennis, and football, which require repetitive loading of the patellar tendon. Basketball is the sport with the highest incidence of patellar tendonitis, hence why it is also known as Jumper's knee. Several studies identify the joints as the most damaged in sports injuries, with the knee and the ankle being the most affected in basketball. Studies show 32% of professional basketball players have patella tendonitis while amateur players have 11 -14% prevalence. NBA players with higher efficiency ratings and higher playing times are more at risk. For patients in the early stages of patellar tendinitis, conservative treatment is the method of choice. Patients with end -stage (Blazina III to IV) disease who have suffered a complete tendon rupture need surgery. Both arthroscopy and open surgery are commonly used. After surgery, dynamic balance and speed ability of the patient will be drastically reduced. It is necessary to improve the dynamic balance and speed among patients so that they can return to their sport. Hence, the need of the study is to find out the effectiveness of BOSU ball and agility training in enhancing dynamic balance and speed in post -operative jumper's knee among basketball players. Methodology: This is an experimental study design comparing the pre -post type done at Tagore College of Physiotherapy. In this study, 20 subjects were included based on the inclusion criteria. The study was conducted over a period of 12 weeks. The first 6 weeks dynamic balance training was given to the players using BOSU ball as three stages. Immediately, after completing the dynamic balance training, players were intended to start agility training for a period of 6 weeks. Total 72 sessions in 12 weeks for 35 -50 minutes, repetition 2 times per day, and 3 days a week. The pre -test and post -test values of dynamic balance on Star excursion balance test (SEBT) and Stork balance test were taken for analysis using paired t test. Similarly, pre -test and post -test values of speed on ¾ court sprint test and 30 -meter sprint test were taken for analysis using paired t test. Result: The statistical reports that the pre -test and post -test mean values and standard deviation values of SEBT were obtained. The pre -test mean and standard deviation values ofStork balance test were 36.55±5.92.The post -test mean and standard deviation values of Stork balance test were 139.65±22.25.The pre -test mean and standard deviation values of ¾ court sprint test were 3.9904±1.0703.The post -test mean and standard deviation values of ¾ court sprint test were 3.4452±0.477.The pre -test mean and standard deviation values of 30 meter sprint test were 5.5165±0.9409.The post -test mean and standard deviation values of 30 meter sprint test were 4.8040±0.8765.On the basis of results received, the study states that there was significant improvement in dynamic balance and speed.The result shows that, the effectiveness of BOSU ball and agility training in enhancing dynamic balance and speed in post -operative jumper's knee among basketball players.Conclusion: The study concludes that BOSU ball and agility training were effective on improving dynamic balance ad speed in post -operative jumper's knee among basketball players.
