Abstract
Objective: To evaluate the ability to maintain postural balance in patients with lower back pain and lumbosacral radiculopathy. Methods: The object of the study was selected patients who were referred for electromyography in connection with lower back pain in the period from September 2023 to May 2024. Based on the EMG results, the patients were divided into groups with and without lumbosacral radiculopathy. Results: The risk of falls (73.25 vs. 38.00; p< 0.05), the weight distribution index (8.57 vs. 5.00;p< 0.05) and the stability index (21.19 vs. 13.16;p< 0.05) were significantly higher in the group with lumbosacral radiculopathy than in the group without lumbosacral radiculopathy. The Fourier index at high and medium frequencies was significantly increased in the group of diseases of the lumbosacral disc (8.27 vs. 5.56; p< 0.05), while the load on the side of radiculopathy was significantly reduced. Conclusion: Patients with lumbosacral radiculopathy had postural balance disorders compared to patients without radiculopathy. Somatosensory disorders in lumbosacral radiculopathy can lead to a violation of postural balance.
