Comparative Effects of Rebound Training and Theraband Resistance Exercise on Agility, Power and Dynamic Balance in Badminton Players With Patellofemoral Pain Syndrome

Numeric Pain Rating Scale

时间窗: 6 weeks

Numeric Pain Rating Scale NPRS is based on 11-point numerical rating scale for determining pain intensity, 0(no pain) to 10(worst pain imaginable) pain intensity .NRS pain has high validity and reliability (β = 0.42 \[95% CI 0.04, 0.80\]

Agility T Test

时间窗: 6 Weeks

Agility will be measured by the agility T - tests high intra-trail reliability of the test (ICC=0.98). The participants were instructed to run 9.14 meters from the starting line to the first cone, touch the tip with their right hand, shuffle 4.57 meters to the left to the second cone, shuffle 9.14 meters to the right to the third cone, touch with their right hand, shuffle 4.57 meters to the left to the middle cone, touch with their left hand, and then back pedal to the starting line.

Vertical Jump Power Test

时间窗: 6 Weeks

To mark the wall at the height of their jump, the participant applies chalk to the tips of their fingers. After standing away from the wall, the individual uses both arms and legs to help project their body upwards and jumps as high as they can. At the peak of the jump, try to make contact with the wall. Power will be measured by Sargent Test. Vertical Jump test is a very common test for measuring explosive leg power intra rater class reliability ICC = 0.903 to 0.934)

40-Yd Speed Test

时间窗: 6 Weeks

Speed will be measured by 40-Yd Sprint Test. The test involves running a single maximum sprint over 40 yards, with the time recorded. The aim of this test will be determine 40-Yd Sprint. Sprints of 40 yd were used to determine quickness ICC \> 0.987

Star Excursion Dynamic Balance

时间窗: 6 Weeks

The SEBT is a functional test that incorporates a single-leg stance on one leg with maximum reach of the opposite leg. The SEBT is performed with the subject standing at the center of a grid placed on the floor, with 8 lines extending at 45° increments from the center of the grid. The 8 lines positioned on the grid are labeled according to the direction of excursion relative to the stance leg. The plane was constructed in a facility with the help of protractor and adhesive tape on the hard tile floor. Dynamic balance check with balance with Star Excursion Balance Test (SEBT) the intra class correlation coefficients ( 0.86 to 0.92)
