Sažetak
Electromyography (EMG) with surface electrodes and POLGON (polarized light
goniometry) are electrodia gnostical methods making it possible to record electrokinesiologic
activity of the muscles. Kinesiologic EMG gives an objective picture of
myoelectric activity during a lovement or while maintaining a position of the body.
The abdomin al and dorsal muscles have shown different va.riations of myoelect r ic
activity in healthy test subjects. The activity of the smooth abdomina,l mu\Scle is very
low in the activities of everyday life, while the oblique abdominal muscles are more
often activated and so are the extensor muscles of the b ~~ e:k . The activity of the m.
sacrospinaiis in healty test subjects when bending or stooping and strai·ghtening -
returning to the erect posture - show a typical bifurcate pattern with lower amplitudes
of myoelectric activity on bending and higher activities on straightening up,
while in the maximally bent (stooped) position the muscle is completely relaxed.
In patients with low back pain inhibition of the normal function of the muscle
has been observer and antalgic activity registered. Thus low back pain becomes accessible
to objective kinesiologic study.
Antalgic activity becomes manifest in the EMG pattern by continuous myoelectric
activity with higher amplitudes on bending (stooping) and reduced amplitudes on
straightening, while in the maximally bent position no relaxation is achieved.
Kinesiologic EMG gives an insight into activation and rela•xation of individual
muscles during exercises and at rest. ·
Kinesiologic EMG has found its application in the programming and following
of kinesitherapeutic procedures and in the evaluat ion of functional damage or injury
to the locomotor system.
