Use surface electromyography in the clinical practice
Dobisová, Anna ; Crhonková, Radka (advisor) ; Demeková, Júlia (referee)
Surface electromyography is a non-invasive method of examination. Surface electrodes localized on the skin above the muscle record action potentials of particular muscles' motor units. Acquired EMG recordings enable to assess muscle activity, muscle fatigue or recruitment of particular muscles during the motion (timing) and muscle coordination. Modern EMG devices are compatible with a scale of sensors that record other biosignals and are able to synchronize them with EMG records. That's why SEMG is applied in neurology, physiotherapy, ergonomics, biomechanics, orthopaedics, prosthetics, sport and in other spheres. As a non-invasive method it has its advantages, but of course its limits as well. Powered by TCPDF (www.tcpdf.org)

A comparison between muscle coordination during dynamic tests by surface electromyography
Gašpárek, Milan ; Valouchová, Petra (advisor) ; Slabý, Kryštof (referee)
Objectives: We evaluate the movement patterns of left-sided radicular syndrome patients on the basis of intervertebral disc herniation L4/L5 or L5/S1 and test group to verify expected verge asymmetry between selected muscles and changes in their timing. Participants: 10 patients with left-sided radicular syndrome caused by intervertebral disc herniation were objects of the reserarch L4/L5 or L5/S1 (7 men, 3 women, average age 37,4 ± 10,67 years old). 6 healthy individuals without vertebrogenic problems were part of the reserarch (2 men, 4 women, average age 27,4 ± 2,6 years old) Methods: During specific tests focused on stabilizing function of musculosceletal system, selected muscles activity was recorded for both groups by SEMG Data analysis: The variation significance between experimental and test group was evaluated by two-tailed t-test. Significance level of p=0.05 was selected for statistical hypothesis testing. Results: We have proved statistically significant asymmetry between right and left side for patients with radicular syndrom. Significant variations were found for muscles timing between group with herniation and test group. Conclusion: Selected muscles activity and involvement sequence changes (timing) were found for patients with intervertebral disc herniation during postural tests,...
