Abstract Background The aim of this study was to find out whether the shear wave elastography (SWE) findings of patients with unilateral lumbar disc herniation (LDH) were related to clinical characteristics. Methods For this purpose, the study group included patients (N = 20; 13 male, 7 female) with complaints of unilateral sciatica, with foraminal stenosis caused by one level of LDH (L4-L5 or L5-S1). An gender-and age-matched control group (N = 27; 16 male, 11 female) was included. All the patients were examined on both the axial and longitudinal planes bilaterally at the same level using a convex array probe (1- 6 MHz, Supersonic Imagine, Aix en Provence, France). Results The sciatic nerve stiffness measured on longitudinal planes of the affected side was significantly higher than unaffected side (p < 0.001) and the control group (P < 0.05). Furthermore, the symptom duration of unilateral LDH is positively correlated with the stiffness the sciatic nerve (r = 0.52, p = 0.019). Conclusion According to these findings, ultrasound imaging can be considered as a useful tool to detect changes in the sciatic nerve due to disc herniation. This technique will have a promising prospect for many patients with unilateral LDH in monitoring stiffness during rehabilitation and before or after surgery.

Abstract Background The aim of this study was to find out whether the shear wave elastography (SWE) findings of patients with unilateral lumbar disc herniation (LDH)were related to clinical characteristics . Methods For this purpose,the study group included patients(N=20; 13 male, 7 female) with complaints of unilateral sciatica, with foraminal stenosis caused by one level of LDH (L4-L5 or L5-S1).An gender-and age-matched control group(N=27; 16 male, 11 female) was included.All the patients were examined on both the axial and longitudinal planes bilaterally at the same level using a convex array probe(4- 15MHz,Supersonic Shear Imaging). Results The sciatic nerve stiffness measured on longitudinal planes of the affected side(21.3 ± 4.1 kPA) was significantly higher than unaffected side (13.2 ± 2.1 kPA) in the patient group (p < 0.001).Meanwhile,the control group with mean value of 12.7±2.1 kPa(left) and 13.5±1.9kPa(right)showed significantly difference between the affected side(all P<0.05). Furthermore,Longer duration of LDH symptoms got stiffer sciatic nerves.(r=0.60).Meanwhile,the symptom duration and VAS scores were also correlated(r=0.52,p=0.019), Conclusion According to these findings, ultrasound imaging can be considered a useful tool to detect changes in the sciatic nerve due to disc herniation. Patients with LDH have higher stiffness of the sciatic nerve compared to control group.And the longer history of the unilateral LDH,the higher of the SWE findings.This technique will have a promising prospect for many patients with unilateral LDH in monitoring stiffness during rehabilitation and before or after surgery.

AbstractThis study aimed to investigate lower-limb muscle activities in gait phases and co-contraction of one gait cycle in patients with lumbar disc herniation (LDH). This study enrolled 17 LDH patients and 17 sex- and age-matched healthy individuals. Bilateral muscle activities of the rectus femoris (RF), biceps femoris long head (BL), tibialis anterior (TA), and lateral gastrocnemius (LG) during walking were recorded. The gait cycle was divided into four phases by the heel strike and top off according to the kinematics tracks. Root mean square (RMS), mean frequency (MF), and co-contraction of surface electromyography signals were calculated. The LDH patients showed enhanced BL RMS during the single support phase (SS), second double support phase, and swing phase (SW) as well as decreased MF of RF during SS and of TA and LG during SW (p < 0.05). The co-contraction of the TA-LG was increased in LDH patients than in the control group (p < 0.05). Positive correlations were observed between TA-LG co-contraction (affected side, r = 0.557, p = 0.020; contralateral side, r = 0.627, p = 0.007) and the Oswestry disability index scores in LDH patients. LDH patients have increased BL firing rate and insufficient motor unit recruitment in specific phases in the lower limbs during walking. Dysfunction in LDH patients was associated with immoderate intermuscular co-contraction of the TA-LG during walking.

Low back pain due to lumbar disc herniation (LDH) is very common in clinic. This randomized controlled trial was designed to investigate the effects of integrative TCM conservative therapy for low back pain due to LDH. A total of 408 patients with low back pain due to LDH were randomly assigned to an experimental group with integrative TCM therapy and a control group with normal conservative treatment by the ratio of 3 : 1. The primary outcome was the pain by the visual analogue scale (VAS). The secondary outcome was the low back functional activities by Chinese Short Form Oswestry Disability Index (C-SFODI). Immediately after treatment, patients in the experimental group experienced significant improvements in VAS and C-SFODI compared with the control group (between-group difference in mean change from baseline, −16.62 points,P<0.001in VAS; −15.55 points,P<0.001in C-SFODI). The difference remained at one-month followup, but it is only significant in C-SFODI at six-month followup (−7.68 points,P<0.001). No serious adverse events were observed. These findings suggest that integrative TCM therapy may be a beneficial complementary and alternative therapy for patients with low back pain due to LDH.

Objective This study was performed to investigate the effectiveness and safety of ultrasound-guided transforaminal nerve block in the treatment of lumbar disc herniation. Methods Sixty patients who underwent treatment for protrusion of a lumbar intervertebral disc in Wangjing Hospital from January 2016 to December 2017 were divided into the study group and the control group. The visual analog scale (VAS) pain scores, the Japanese Orthopaedic Association (JOA) scores of the lumbar vertebra, PRI (pain rating index), and PPI (present pain intensity) were recorded at 30 minutes, 1 week, and 3 months after the operation. Results There were significant differences in the VAS, JOA, PRI, and PPI scores between the study group and control group. Conclusion Ultrasound guidance can improve the efficacy and safety of transforaminal nerve block in the treatment of lumbar disc herniation and shorten the operative duration.
