Introduction. Radicular low back pain is one of the most common medical problems. The aim of this study was to evaluate the diagnostic accuracy of MRI and electrodiagnosis in lower extremity radicular pain in relation to history and clinical findings. Methods. In this cross-sectional study, we studied 165 sciatalgic subjects. A comprehensive history and physical examinations were taken from the subjects and recorded, and then MRI scanning and electrodiagnostic (nerve conduction velocity and electromyography) tests were performed. Results. From 152 subjects who remained in the study, 67 cases (44.1%) had radicular pain in left lower limb, 46 (30.3%) in right, and 39 (25.6%) in both lower limbs. 104 cases (68.4%) had shown some type of abnormalities in both MRI and electrodiagnosis, 30 (19.7%) had shown this abnormality only in MRI, and 21 (13.8%) only in electrodiagnosis, while 10 cases (6.5%) had both normal MRI and electrodiagnostic studies. Coordination rates of MRI and electrodiagnosis with clinical findings were 58.6% and 89.5%, respectively. Conclusion. In many MRI negative but symptomatic subjects, electrodiagnosis has an important diagnostic value.

The Impact

Abstract Context: Knowledge of the kinetic changes that occur during sloped running is important in understanding the adaptive gait-control mechanisms at work and can provide additional information about the poorly understood relationship between injury and changes in kinetic forces in the lower extremity. A study of these potential kinetic changes merits consideration, because training and return-to-activity programs are potentially modifiable factors for tissue stress and injury risk. Objective: To contribute further to the understanding of hill running by quantifying the 3-dimensional alterations in joint kinetics during moderately sloped decline, level, and incline running in a group of healthy runners. Design: Crossover study. Setting: Three-dimensional motion analysis laboratory. Patients or Other Participants: Nineteen healthy young runners/joggers (age  =  25.3 ± 2.5 years). Intervention(s): Participants ran at 3.13 m/s on a treadmill under the following 3 different running-surface slope conditions: 4° decline, level, and 4° incline. Main Outcome Measure(s): Lower extremity joint moments and powers and the 3 components of the ground reaction force. Results: Moderate changes in running-surface slope had a minimal effect on ankle, knee, and hip joint kinetics when velocity was held constant. Only changes in knee power absorption (increased with decline-slope running) and hip power (increased generation on incline-slope running and increased absorption on decline-slope running in early stance) were noted. We observed an increase only in the impact peak of the vertical ground reaction force component during decline-slope running, whereas the nonvertical components displayed no differences. Conclusions: Running style modifications associated with running on moderate slopes did not manifest as changes in 3-dimensional joint moments or in the active peaks of the ground reaction force. Our data indicate that running on level and moderately inclined slopes appears to be a safe component of training regimens and return-to-run protocols after injury.

Objective — To explore the diagnostic value of bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasonography in patients with venous thromboembolism. Methods — Select 97 patients with high-risk Caprini scores and high-risk Padua scores from December 2019 to April 2021 in the Second Affiliated Hospital of Shandong First Medical University as the research objects, all of whom completed bedside transthoracic echocardiography combined with bedside lower limbs or upper extremity venous ultrasound examination; compare the results of different ultrasound examinations with spiral CT pulmonary angiography (CTPA); analyze the diagnostic value of bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasound in patients with pulmonary embolism. Results — 97 patients with high-risk Caprini score and high-risk Padua score were confirmed by CTPA in 41 cases of pulmonary embolism; bedside transthoracic echocardiography, bedside lower extremity or upper extremity venous ultrasonography for venous thromboembolism were all positive in 35 cases; among them, 32 cases were confirmed by CTPA as pulmonary embolism, and the diagnostic compliance rate with the gold standard was 87.63%; bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasonography had a diagnostic sensitivity of 78.05% and a diagnostic specificity of 94.64%; Conclusion — Bedside transthoracic echocardiography and bedside lower extremity venous ultrasonography combined for venous thromboembolism can improve the specificity of diagnosis, and it is worthy of popularization and application.
