Effect of High-Induction Magnetic Stimulation on Elasticity of the Patellar Tendon

Abstract

Nowadays, a high-induction magnetic stimulation is starting to be increasingly applied as a biophysical stimulation in the conservative treatment of the degenerative locomotor system diseases. These are mainly in correlation with the changes in soft tissue elasticity, which should be positively influenced by the flow-induced electrical currents of high current density during high-induction magnetic stimulation. This assumption was verified within the interventional and prospective study using the ultrasound elastography. The group consisted of 6 volunteers, whose elasticity of the patellar tendons was measured using the 2D shear-wave ultrasound elastography. The volunteers were then exposed to a 20-minute high-induction magnetic stimulation session with a frequency of 20 Hz, in 2 s package intervals, with a 5 s pause, and a induced electric current density of 100 Am−2 in the tendons area. A tendon tension was measured five times for all volunteers, where mean tension at the marked area of the tendon, as well as the highest point tension indicated by the Q-Box, was monitored. The measurement results show that high-induction magnetic stimulation has an influence on the patellar tendon tension change, which occurred in the case of all involved volunteers when the patellar tension was decreased.

Advances in non-coding RNA in tendon injuries

“…Biophysical stimulation refers to a range of therapeutic modalities to assist tendon healing, but is limited to well-vascularized tissues that have a high likelihood of healing without surgery, or as an adjunct to surgery ( Benazzo et al, 2008 ). The above therapies mainly include ultrasound therapy ( Lu et al, 2016 ), magnetic field therapy ( Xu et al, 2014 ; Prucha et al, 2018 ), cryotherapy ( G et al, 2013 ), and physical therapy ( G et al, 2013 ), each with its own advantages and characteristics.…”

Tendon and Ligament Healing and Current Approaches to Tendon and Ligament Regeneration

“…Biophysical stimulation describes a series of conservative treatment modalities that can be used to assist in tendon and ligament healing, but is typically only applied in well‐vascularized tissues that have a high likelihood of healing without surgery, or as an adjunct to surgery . These methods include physical therapy, cryotherapy, magnetic fields and ultrasound …”

Effects of the High-Induction Magnetic Stimulation on Viscoelastic Properties of the Biceps Brachii

“…However, from the viewpoint of the HIMS action it seems that the therapy could be suitably employed for the treatment of soft tissues [6]. The assumption of positive HIMS effects is also supported by research implemented at the cellular level [11], [12].…”

“…The research results available are even more restricted when considering the therapy with the use of the HIMS. However, the use of pulsed electromagnetic fields (PEMF) at different intensities and frequencies brought positive therapeutic results [3]- [6] and presented no hazard in terms of affecting the electric conduction system in the myocardium [2]. In general, the research available is particularly aimed at low-intensity fields in the therapy of joints, e.g.…”
