简要总结
The tape will be applied on the lumbar area bilaterally to the spine without creating any tension.
The possible variation in the isometric hip strength is measured with the mDurance®, surface electromyography and the Lafayette® dynamometer. A kinesiology tape was used as a placebo tape and the magnetic tape was used in a randomized experimental way.
详细描述
A doble-blind clinical trial study, is designed where subjects with low back pain will be selected and blinded to receive the Magnetic Tape® 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 patient does not know 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.
