Many studies have been completed to determine how muscles work. One of the aspects to study is the muscle response and how to measure it. The main aim of this study was to build a noninvasive measuring system that would be simple to use and would measure the muscle response as close to the muscle as possible. The measuring method was based on a magnetic(More)
The variability of fiber type distribution in nine limb muscles was examined with histochemical and tensiomyographical (TMG) methods in two groups of 15 men aged between 17 and 40 years. The aim of this study was to determine the extent to which the relative occurrence of different fiber types and subtypes varies within human limb muscles in function to(More)
The histochemical and biomechanical relationships of limb muscles are examined in two groups of 15 men aged between 17 and 40 years. Seven muscles are chosen: biceps brachii, triceps brachii (TB), flexor digitorum superficialis, extensor digitorum, biceps femoris, tibialis anterior and gastrocnemius caput mediale (GCM). The aim of the preliminary study is(More)
Impedance between the electrode inserted in a root canal of a human tooth and the outer electrode placed on the oral mucosa serves as a measure of the root canal length, a vital parameter necessary for efficient endodontic procedure in dentistry. For better understanding of current conduction through the tooth, the impedance has been measured on extracted(More)
Alternative current (ac) current conduction through a human tooth has been investigated through numerical simulation. Numerical calculation of impedance between the file (electrode) inserted in the root canal of the tooth and the outer electrode enables investigation of the impedance method used in dentistry for evaluation of the root canal length.(More)
PURPOSE To compare the strength and endurance of knee extensors in subjects after paralytic poliomyelitis as well as to extend the comparison to healthy subjects. METHOD Twenty subjects after poliomyelitis with new symptoms (SYM group), 10 without new symptoms (ASYM group) and 15 healthy controls were included. To determine strength, isometric maximal(More)
A three dimensional finite element model of the cut:meous wound stimulated by direct electric current was built by means of the finite element method, As was assumed in part I of this article, the endogenous electrical properties of the injured skin are' beneficial and necessary for a normal course of healing. Therefore, an attempt was made to determine the(More)
Muscle responses to tetanic electrical stimulation were detected by the non-invasive tensiomyographic (TMG) measuring method. The main objective of this study was to find out whether the TMG measuring method is suitable for monitoring the unfused tetanus (stimulation frequencies ranging from 1 Hz to the fusion frequency (ff)--the frequency at which tetanus(More)
