Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is performed by a physiotherapist.
The people will be divided into two groups randomly. One experimental group and one control group.
Each test consists of recording the maximum strength of the hip abduction in the first isometry of one lower limb and after the other in the supine decubitus position. Subsequently, the patient is placed in a sitting position and performs an internal and external maximum rotation of each hip actively. The rotations are then evaluated passively. The tape is then placed without adhering it between the anterior superior iliac crests to immediately afterwards measure the maximum force and the joint range in rotation. After ten minutes the tape is removed from the body and the strength and joint range of the rotations are measured again.
Each subject of the both groups will be given 3 repetitions of each test and the average value will be obtained. The duration of each test will be 3 seconds.
The time used in each session to perform the tests is 30 minutes.
At 24 hours without the tape, the maximum force and the rotation of the hip will be tested again.
Force and joint tests are standardized by other publications.
The experimental group will be the application of magnetic fields less than 50 Hz for 10 minutes between the anterior superior iliac spines using a magnetic tape without adhering the tape as it is an adhesive tape but we want not to intervene the possible tension produced by the adhesion of the tape in the body.
The control group will be the one that apply a tape without magnetic properties. Both tapes are equal to sight and touch.
The tape remains in place as the force test is performed in supine so no need for restraint and to assess the hip rotation in sitting position is held with the waist of the pants.
With the application of low intensity magnetic fields we intend to normalize the electrical signal that reaches the pelvic musculature helping to normalize the tone of the periarticular muscles, equalizing the force produced by both limbs and equaling the degrees of rotation of both hips. force and joint tests are standardized by other publications.
The maximum force, time to perform the maximum force and average force produced when performing abduction of lower limbs using the Lafayette dynamometer and a goniometer to assess the degrees of mobility of the hip joint bilaterally will be assessed.
One of the tapes will be numbered with the number one and the other tape with the number two. The decision of which tape will take each number will be made at the moment of beginning the study using the same random program to group the subjects. Said information will only be known to the principal investigator and this will tell the physiotherapist what number of the tape to use in each subject as indicated by the random designation program.
The subject will not know what kind of tape is what they have.

Summary
Brief summary
The purpose of this study is to increase the maximum and average strength of the hip abduction in supine decubitus and the improvement of joint movement (ROM) of hip rotation in sitting.
The hypotheses of the study are:
- When a low intensity magnetic field is applied between the anterior superior iliac spines, an increase in force is produced when hip abduction is performed and an increase in ROM of hip rotation is produced.
- Immediately after the application of the magnetic field there is a significant increase in the average force performed during the 3-second test when hip abduction is performed and the range of motion of the hip rotations is improved.
- After 10 minutes of application, the significant increase in the average force during the 3-second test is maintained when performing the hip abduction and the range of movement of the hip rotations.
- After 24 hours from the treatment of magnetic fields for 10 minutes, the significant increase in force and range of motion of the hip rotations is maintained.
