Electromyographic study of selected neck muscles in patients with torticollis
Pospíchalová, Tereza ; Pánek, David (advisor) ; Malá, Jitka (referee)
Title: Electromyographic study of selected neck muscles in patients with torticollis Objectives: The aim of the study was to determine the electrical muscle activity and the symmetry of the electrical muscle activity of selected neck muscles in patients with torticollis during flexion in three different positions - standing, sitting, lying on the back. Methods: The study involved 8 probands aged 27 - 60 years. The Noraxon TeleMyo 2400T G2 surface electromyography device for telemetry data transmission technology with a sampling frequency of 1500 Hz was used for the measurement. The surface electrodes were applied to five target muscles bilaterally, namely the sternocleidomastoid muscle, scaleni muscles, suprahyoid muscles, infrahyoid muscles and trapezius muscle upper part. Subsequently, the probands performed cervical spine flexion fifteen times in a randomized order of positions in synchronism at the same speed by setting the metronome to 60 bpm. The electrical muscle activity of the examined muscles was used in average %MVC values in comparison right/left, as well as changes in average %MVC values depending on positions and symmetry of electrical muscle activity during neck flexion using Pearson's correlation coefficient. Results: The values of the average %MVC of the contralateral SCM against...

Neurocranial asymmetry from normal shape to pathology
Forinová, Michala ; Velemínská, Jana (advisor) ; Bigoni, Lucie (referee)
Neurocranial asymmetry from normal shape to pathology Abstract: The bachelor thesis deals with the most frequent asymmetry of human skull - deformational plagiocephaly. Deformational (positional) plagiocephaly is the deformity of the skull, which is casued by external forces on developing, little rigid, skull of infants. An increased incidence of this deformity was noticed after 1992, when American Academy of Pediatrics marked supine position as the most safe sleeping position for infants, which decreases risk of Sudden infant death syndrome (SIDS). This thesis includes the context of this deformity such as the correct development of the skull, craniosynostosis or torticollis. Craniosynostosis, caused by premature fusion of suture, can lead to similiar resulting shape of the skull. To differentiate craniosynostosis from deformities caused by external forces is very important from the point of clinial view - craniosynostosis can lead to increasing of intracranial pressure and other complications. Expansion of deformational plagiocephaly can be connected in some cases with torticollis, which leads to asymmetrical posture of a head and following confirmation.
