Hip Manipulation in Basketball Players (Manual Therapy)

Assessment of the Impact of Hip Manipulation on Muscle Strength and Stiffness as Well as Motor Functionality of Basketball Players During Training

Currently, it is difficult to find studies in the literature assessing the impact of manual therapy on preventing lower limb injuries in basketball players, which may later translate into improved strength and balance in athletes, when planning training or therapy programming, e.g. in patients after ankle sprains.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of MVC.	Muscle EMG is an assessment of electrical characteristics during the test, the electrical source of which is the muscle membrane potential, and measured in μV.	The study will be conducted 3 times during one training session (before the intervention, after the intervention and after training). Each isometric muscle test lasts 3 seconds.
Assessment of MVC.	Muscle EMG is an assessment of electrical characteristics during the test, which is measured by the repetition frequency of muscle motor unit discharges, which is measured in Hz, at the same time of the test.Time	The study will be conducted 4 times during one training session (before the intervention, after the intervention and after training).Each isometric muscle test lasts 3 seconds.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of proprioception.	Assessing proprioception is an assessment of the angular position of a joint and then an attempt to reproduce it, measured in degrees.	The test will be performed three times during one training session (before the intervention, after the intervention, after the training). Each joint measurement will be performed at three settings: 15, 30, 45 degrees.
Y balance test	Consists of the volunteer standing on one leg while simultaneously stretching the other lower limb in 3 different directions. These are: anterior, posteromedial and posterolateral.	The test will be conducted three times during one training session (before the intervention, after the intervention, after training).
Standing Long Jump Test	Attempt to jump as far as possible while landing on both feet without falling backwards. The distance will be measured and given in centimeters.	The test will be conducted 3 times during one training session (before the intervention, after the intervention, after the training). Each test is repeated 3 times.
