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,...
