| Summary: | Background. Low back pain is one of the most urgent medical and socio-economic problems of society, accompanied by a global increase in the number of years lived with disability (YLDs). The majority of studies associate low back pain with limitation of motor function of the spine and muscle control of the lumbar-pelvic area, however, in a number of reports such a connection was not found.
Purpose – to conduct a comparative assessment of orthopedic status and the results of clinical tests of motor control in asymptomatic volunteers and in patients with lumbar osteochondrosis with moderate pain syndrome.
Materials and Methods. Design: a retrospective controlled study. Material: orthopedic examination protocols of 30 asymptomatic volunteers aged 20–30 years (control group) and 60 patients aged 20–40 years with lumbar osteochondrosis and moderate pain syndrome (main group). Methods: clinical: lumbar pain intensity was assessed using VAS; the level of ODI according to Oswestry Disability Questionnaire, version 2.0; paravertebral muscle tone, lumbar spine mobility according to the Schober method; mobility of the entire spine according to the «finger-floor» test; motor control of the lumbar-pelvic muscles was tested; statistical.
Results. Low back pain according to VAS is considered moderate; the ODI disability level indicated a moderate decrease in activity. The obtained data significantly exceeded the similar indicators of asymptomatic volunteers (p < 0.05). The results of the «finger-floor» and Schober tests revealed a reliable limitation of flexion (p < 0.01 and p < 0.05, respectively). The results of motor control testing revealed 3 types of pathological motor patterns during flexion: 1) fixation of all parts of the spine with flattening of the lumbar lordosis, backward tilt of the pelvis, and hyperextension of the hip and knee joints in 45% of patients and 5% of volunteers; 2) fixation of the cervical and thoracic spine with insignificant mobility in the lumbar spine, tilting of the pelvis backwards and extensor position in the joints in 22.5% and 10%, respectively; 3) moderate fixation of the spine with forward pelvic tilt and flexion in the joints in 32.5% and 30%, respectively.
Conclusions. The presence of moderate low back pain and associated myotonic syndrome in patients with lumbar osteochondrosis is accompanied by inconsistency in the activation of the muscles of the lumbopelvic region with a change in the motor stereotype. |
