IS THERE A RELATIONSHIP BETWEEN PAIN, LIMITS OF STABILITY AND SENSORY INTERACTION BALANCE IN PATIENTS WITH LUMBAR DISC HERNIATION? A CROSS-SECTIONAL STUDY

ABSTRACT Objective To evaluate the intra- and interobserver reliability of the Lee et al. classification for migrated lumbar disc herniations. Methods In 2018, Ahn Y. et al. demonstrated the accuracy of this classification for radiologists. However, magnetic resonance images are often interpreted by orthopedists. Thus, a cross-sectional study was conducted by evaluating the magnetic resonance images of 82 patients diagnosed with lumbar disc herniation. The images were evaluated by 4 physicians, 3 of whom were spinal orthopedic specialists and 1 of whom was a radiologist. The intra- and interobserver analysis was conducted using the percentage of concordance and the Kappa method. Results The report of the classifications used by the four observers had a higher proportion of “zone 3” and “zone 4” type classifications in both evaluation moments. The most affected anatomical levels were L5-S1 (48.2%) and L4-L5 (41.4%). The intra- and interobserver concordance, when comparing both moments evaluation of the complementary examinations of the participants involved, was classified as moderate and very good. Conclusions Lee’s classification presented moderate to very good intra- and interobserver reliability for the evaluation of migrated lumbar disc herniation. Level of evidence II; Retrospective Study.

Objective To determine whether pain is associated with gait instability in patients with lumbar disc herniation (LDH). Methods This retrospective cross-sectional study used data from electronic medical records. Among patients with lumbar back pain caused by LDH between January 2017 and July 2019, patients that underwent gait analysis were included. LDH was diagnosed using magnetic resonance imaging. An OptoGait photoelectric cell system was used for gait evaluation. Instability was measured using a gait symmetry index. Multivariate linear regression analysis was performed to determine the association between lumbar pain and gait instability. Results A total of 29 patients (12 females [41.4%] and 17 males [58.6%]; mean ± SD age, 40.6 ± 12.0 years) with LDH were enrolled in the study. With each 1-point increase in lumbar pain on the numeric rating scale, the symmetry index of the stance phase (0.33; 95% confidence interval [CI] 0.04, 0.62), swing phase (0.78; 95% CI 0.14, 1.43) and single support (0.79; 95% CI 0.15, 1.43) increased. Conclusions Gait instability in patients with LDH may occur due to an increase in pain.

Injury Causation

Abstract This article presents the current science regarding the causation for herniated lumbar discs, taken from the second edition of the AMA Guides to the Evaluation of Disease and Injury Causation. Sciatica is a relatively common disorder; point prevalence population estimates range from 2% to 5%. People with sciatica may or may not have lumbar disc herniations (lumbar herniated nucleus pulposus). Sciatica is described by a variety of terms, including radiculopathy, lumbosacral radicular syndrome, and nerve root irritation. Different definitions of sciatica have been used in epidemiologic surveys, and studies concerning sciatic pain or sciatica generally have used self-reported risk factors in a cross-sectional design—these studies have drawn contradictory conclusions regarding the risk factors associated with lumber radiculopathy. Insufficient scientific evidence exists to justify attributing the cause of lumbar disc herniation to any minor trauma event or ergonomic risk factor; supposed “post hoc ergo propter hoc” (after this, therefore because of this) associations show only association, not causation. The article includes several tables, including risk factors for lumbar disc herniation, risk factors for sciatica, and a summary of evidence for low back pain.

Objective: Lumbar disc herniation is a common disease that affects the quality of life of patients. The study aimed to assess the severity of the disc herniation on magnetic resonance imaging and neurological conduction disorder on Electromyogramme (EMG). Methods: Cross-sectional studies included 40 patients who were diagnosed lumbar disc herniation by clinical features and magnetic resonance imaging in Thua thien Hue Rehabilitation hospital from January 2016 to Dec 2016. Results: Clinical Features: The rate of Lombalgia was 85%, Schober score (+) was 60%, limitation of lumber movement was 65%. There were 45% patients having 2 sites of disc herniation on lumber MRI. Motor conduction velocity of posterior tibia nerve and deep febularis nerve in the side with disc herniation were 43.62 ± 7.53 ms and 45.99±5.74 ms consecutively lower than those in the side without disc herniation. F wave frequence of posterior tibia nerve and deep febularis nerve in the side with disc herniation were 32.63±14.05% and 29.82±12.29% consecutively lower than those in the side without disc herniation. Conclusion: there was a relationship between clinical features, lumbar MRI and change of nerve conductions on EMG in patients with lumbar disc herniation Key words: disc herniation, MRI, EMG, lombalgia
