Abstract
Therapeutic methods taking advantage of low-frequency electromagnetic fields, or in other words, electrical currents contactless-induced by time-variable magnetic fields, enjoy an ever-growing interest in rehabilitation medicine. A great interest is paid to the question of using non-conventional techniques, such as the High Induction Magnetic Stimulation (HIMS). Based on therapeutic principles, it is possible to expect positive effects of this therapy, but this problem has not yet been considered, and thus, there are no research results supporting the HIMS application. Due to this, the target of the article presented here is to study effects of the HIMS on viscoelastic properties of skeletal muscles, since this research has till been missing. Within the framework of the present study, the HIMS was applied to 15 subjects and viscoelastic properties of the muscle were measured before and after the application. The evaluation of hysteresis curves acquired show obvious effects of the HIMS on viscoelastic muscle characteristics. After the HIMS application, the muscle tone was decreased and the elasticity of the tissue exposed was increased in the sample studied.
Highlights
In rehabilitation medicine, ever-growing attention is being paid to problems of the therapy of soft tissues with the use of electromagnetic fields
Magnetotherapy is a frequently used approach and many commercial devices have been designed for this treatment modality
We have focused on the High-Induction Magnetic Stimulation (HIMS) effect on connective tissue - patellar tendon
Summary
Ever-growing attention is being paid to problems of the therapy of soft tissues with the use of electromagnetic fields. The High-Induction Magnetic Stimulation (HIMS) is a therapeutic method using high-intensity fields (up to 2.5 T), which produce high current density in the tissue exposed [2]. Insufficient attention has been paid to the therapy of the locomotor apparatus with the use of the HIMS and results of appropriate studies dealing with this problem are not available. Magnetotherapy is a frequently used approach and many commercial devices have been designed for this treatment modality.
