Abstract

Quantitative analysis of kinesiologic electromyiographic activities (EK) of
sacrospinal muscles during lateroflexion movements was applied in 21 healthy
subjects and 74 patients with chronic low back pain, to analyzing kinematic parameters
and muscular activity.
All the examined kinematic indicators (duration, speed and movements amplitude)
were ·in patients with low back pain of •signifi cantly worse values than in
healthy ones. The low back patients have during •lateroflexion movement to the
right significantly lower speed and longer duration of movement, while amplitude
remains unchanged. During lateroflexion to the left speed and amplitude are significantly
lower, and duration remains unchanged. So, speed of movement to the
right was decreased with maintained amplitude (duration of movement was prolonged),
and to the left was lowered because of decreased amplitude with m~:intained
duration.
,EMG activity of sacrospinal muscles was higher in all the phases of movements
in patients with low back pain, than in healthy ones. The activity of left
muscle, 'in all the phases of the movements, was higher than the activity of the
right one, except the movement from maximally lateral decline to the left in
vertical posture. The greatest activity, both in healthy subjects and in patients with
low back pain too, was registered for agonistic sacrospjnal muscle at movement
from maximaf decline into vertical posture. During lateroflexion movement to the
right, EMG activity was significantly lower bi!aterally, than at lateroflexion
movement to the left, both in healthy subjects and in patients.
The very method of kinesiologic analysis of lateroflexion movements, can be
very practical for functional diagnostics of spine and for the follow-up of therapy
effect.
