About
The purposes of this study are:
- To examine the combined effects of Yellow CPPNLT and conventional treatment on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.
- To examine the combined effects of Green CPPNLT and conventional treatment on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.
3 3- To compare between the effects of Yellow CPPNLT and Green CPPNLT on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.
Full description
Jumper's knee is an overuse injury of the tendon that alters the knee due to repeated stress of activities. Symptoms include pain in the front of the knee. The tears are typically caused by accumulated stress on the patellar or quadriceps tendon. As the name implies, the condition is common in athletes from jumping sports, where there is a high demand for the speed and power of leg extensors. These sports often lead to high eccentric quadriceps loadings, such as volleyball, track (long and high jump), basketball, long-distance running, and skiing. The prevalence of jumper knee is not well examined so far. For non-elite adult athletes the prevalence varies between 14.4% and 2.5% for different sports.Only 2.4% of adolescent professional soccer players sustain PT. However, knee pain, focal tenderness or even acute episodes of PT have a major impact on each player's development, time off the pitch, and career.Bioptron was used for treatment of arthritis, neck&back pain by stimulating blood circulation, reducing inflammation and relieving muscle spasm. There are some studies that have discussed the extent of the effect of the Bioptron Light Therapy on musculoskeletal disorders such as; rotator cuff tendinitis, tennis elbow, carpal tunnel syndrome, acute patellar tendinopathy and acute ankle sprain. There is a lack of the evidence of the clinical guidelines of patellar tendinitis. Up to our knowledge, there is no clear recommendation about efficiency of different colors of Bioptron light therapy on jumper knee. So; this study will be conducted to determine efficiency of yellow and green colors of polychromatic non-coherent light. Sixty subjects will participate in this study and will be divided randomly into three equal groups.Group A (Study group): Will receive green filter of bioptron light therapy and conventional treatment for jumper knee,group B (Study group): Will receive yellow filter of bioptron light therapy and conventional treatment for jumper knee and group C (Control group): Will receive conventional treatment (ice application+ exercise program) for jumper knee.
