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.
Highlights
High-induction magnetic stimulation (HIMS) is starting to be increasingly applied in the context of conservative treatment of degenerative locomotor system diseases
In both approaches, positive results have been recorded for various applications in conservative treatment of degenerative locomotor system diseases
Using Wilcoxon’s rank-sum test during evaluation of the statistical significance of median differences, before and after the HIMS, it was found among individual volunteers that there is a statistically significant difference before and after the application of HIMS among all volunteers. e p value of the test statistics was in all cases lower than 0.05 in both monitored groups dependent on the evaluation methods M1 and M2
Summary
High-induction magnetic stimulation (HIMS) is starting to be increasingly applied in the context of conservative treatment of degenerative locomotor system diseases. E intensity of a magnetic field in the HIMS is between 0.1 and 2.5 T in contrary to lowintensity fields (
