Brief Summary

The goal of neurodynamics is to restore homeostasis of peripheral nerves. In the current context there is varied evidence that links neurodynamics with clinical pain treatments or different pathologies, but little evidence regarding changes in the functionality of athletes, which could be related to improvements in performance. The main objective of the study is to determine if the neurodynamic technique is effective in increasing the range of hip mobility and in increasing the jump with counter movement. Randomized, simple blind clinical study. 15 trampoline jumping gymnasts will be randomized to the two study groups: experimental (active sciatic neurodynamics techniques) and control (without intervention). The intervention will last 4 weeks, with 3 weekly sessions of approximately 5 minutes each. The study variables will be the range of hip flexion movement (goniometry) and the countermove jump (My Jump® application). A descriptive statistical analysis will be performed calculating the main statistical characteristics. The sample distribution will be calculated using a Shapiro-Wills analysis. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula. It is intended to observe improvement in the range of hip flexion movement and in the jump with countermovement.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline hip flexion after treatment and at month

    Using a universal goniometer. The subject will be placed supine on a stretcher, identifying the lateral condyle of the femur with a marker, as well as the head of the fibula and the fibular malleolus. The goniometer axis will be placed on the projection of the greater trochanter of the femur. One of the arms of the goniometer arms will be placed parallel to the table (checked with a level). The athlete will be asked for active hip flexion by keeping the knee and ankle in the extended position, being careful not to bend the knee, or swing the pelvis backwards and without turning the hip to external rotation. The other arm of the goniometer will be placed in the direction of the line between the head of the fibula and the fibular malleolus. The unit of measure is the degree, a numerical value whose normal range is 0º-120º

    Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcomes (1)

  • Change from baseline jump height with counter movement after treatment and at month

    Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental group

EXPERIMENTAL

Each session will last a maximum of 5 minutes, taking place for 3 days a week, over a period of 4 weeks. The intervention will be performed at the start of training (before warm-up).

Other: Neurodynamic training

Control group

NO INTERVENTION

Athletes included in the control group will not perform any intervention, continuing with their usual routine.

Interventions

Starting from a sitting position on a stretcher, with dorsolumbar flexion, it is required to maintain that posture throughout the exercise. Sliding with the straight leg sitting consists of performing alternate movements. First, knee extension and dorsal ankle flexion will be performed, increasing neural tension, combined with cervical extension (to decrease neural tension) in the first instance. Subsequently, knee flexion and plantar ankle flexion (decreasing neural tension) combined with cervical flexion (increasing neural tension) will be performed. The dosage of the technique will be: two seconds for each movement, with 10 repetitions of each one. All sessions will be led by one of the group's researchers.
