Changes in Blood Flow in the Application of Magnetic Tape in Patients With Low Back Pain. RCT
Changes in Blood Flow in the Lower Limb With the Application of Magnetic Tape in Patients With Low Back Pain. Double-blinded Clinical Trial.
調査の概要
詳細な説明
A double-blind randomized clinical trial is designed where subjects with low back pain will be selected and blinded to recieve the Magnetic Tape® (tape with magnetic effects of less than 2 Gauss) or placebo Tape. Likewise, the evaluator who puts the Magnetic Tape® does not know what material he is using, as it is supplied by another researcher. The sonographer also does not know if the patient has low back pain or not or what tape will be placed on him.
The recommendations of the "Consolidated Standards of Reporting Trials" (CONSORT) will be followed. All participants will receive a participant information sheet and sign informed consent. Patients aged 18 to 65 years with low back pain will be recruited from different private clinics in the city of Valencia, Spain.
The hypothesis is that when Magnetic Tape® comes into contact with electromagnetic fields such as those generated by living beings, due to the movement of electrical charges (ions), as defined by Ampere's Law, the domains of the tape are oriented or aligned in parallel with the external magnetic field creating a magnetic flux with a north pole and a south pole. This generated field in turn produces a magnetic induction proportional to the variation of the magnetic flux, as defined by the Faraday Law.
This electric potential produces a redistribution of the electric charge (ions) generating a magnetic field due to the orientation of the tape domains, then exerting a force on the moving charges within the electrolyte.
Physiological, Lorentz's Law, regulating Magnetic Tape® aberrant electromagnetic fields.
The protocol for data collection will be as follows:
After signing the informed consent and data protection, the groups with low back pain will be formed that will receive the application of both Magnetic Tape® and the intervention of a placebo tape. To avoid that the order of the intervention influences the results of the study, the subjects will be randomized into two different groups, Group A and Group B. Group A will receive Magnetic tape® and Group B will do the opposite.
To standardize the location of the tape application, the patient will be placed in the prone position and the L4 spinous processes will be identified by marking them with a pen. Once L4 is located at the level of the iliac crests, the therapist will palpate the next spinous process down to the level of L5, and then it will be marked. The tape will be applied transversely covering the paravertebral skin at both levels.
Afte this protocol ultrasound will be applied, evaluating the characteristics of blood flow by means of ultrasound in the common femoral artery using pulsed power doppler. An Alpinion ECube 12 ultrsound machine with a L3-12H linear probe with a 64 mm footprint will be used. The variables of Peak systolic PS velocity in (cm/s), peak diastolic velocity (DF) in (cm/s), the difference between distolic an systolic (S/D), the pulsatility index (PI), the resistance index (IR) and the artery diameter in (cm) will be taken.
To assess pressure pain in the spinous processes, a Wagner Force Dial - FDK 20 algometer with a circular contact surface of 1 cm2 will be used. The sensation of perceived pain will be performed on the paravertebral skin of each level using the pinch technique and assessing it with the VAS scale. Both the algometer and pinch measurements will be repeated twice at each level leaving at least 1 minute between measurements.
During the pain measurement phase, each participant will be in the prone position where assessments will be made from L1 to S4. Afterwards, they will be placed in a supine position and for three minutes to adjust to the room environment and relax, the ultrasound measurements were taken. Subsequently, a tape will be placed and the perceived pain, pressure pain and vascular parameters will be measured again.
