Abstract
Objective. To compare electroneuromyography (ENMG) characteristics of sensomotor innervation status of lower limb muscles in patients with different level injuries in the thoracic and lumbar spine.
Material and Methods. Findings of global (maximal voluntary muscle tension) and stimulated (M-response, Н-reflexes) ENMG were analyzed in 48 patients aged 11 to 55 years. All patients were divided into three groups depending on the injury level.
Results. The most marked ENMG signs of functional insufficiency in pre- and postoperative periods were registered in patients with spinal cord injuries at the D9 through D12 levels, which topologically correspond to localization of segmental neuronal populations responsible for formation of spinal motor centres controlling voluntary and reflex activity of lower limb muscles.
Conclusion. Consideration of the study results can be useful in predicting functional outcomes of surgical treatment and rehabilitation of patients with consequences of spinal cord injury.
