Objective: To observe the effect of Qiang Jin exercises on the muscle strength and activity of lumbar spine in patients with lumbar disc herniation., Methods: From March 2016 to September 2017, at the Department of Orthopaedics, Shuguang Hospital, Shanghai University of Traditional Chinese Medicine, a total of 110 subjects were enrolled, and 98 eligible subjects were screened. The subjects were randomized by stratified randomization and divided into experimental group and control group, 49 cases in each group, 25 males and 24 females in the experimental group, 25 males and 24 females in the control group. The experimental group exercised with Qiang Jin exercises, one time each morning and evening, each time10 sets were made;the control group used classic rehabilitation training, training twice a week, and three months was a course of treatment. After 12 weeks of training, the muscle strength and activity of the lumbar spine were evaluated and compared with the muscle strength and activity of the lumbar spine before training., Results: The experimental group and the control group had different muscle strength and activity of the lumbar spine before and after treatment ( P <0.05). There was no significant difference between two groups after treatment( P >0.05)., Conclusion: Qiang Jin exercises can effectively improve the muscle strength and activity of the lumbar spine and improve the daily living ability of patients.

Purpose: To summarize the scope of nomenclature and measurement methods used to document endplate defects in the health sciences literature., Methods: The scoping review followed the York framework and was reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. The databases of PubMed, Scopus, Embase and CINAHL were searched using key terms. Screening and selection were conducted by two independent reviewers. A standardized, pilot-tested form was used for extracting data, which were analyzed descriptively., Results: The review included 211 studies, originating from 29 countries, with the USA (18.8%) and China (12.26%) as leading contributors. Thirty-four different terms for structural endplate defects were reported, but were never defined in most studies (65%). Of the 34 different terms used, some appeared to represent the same phenomenon, while the same terms were occasionally defined differently between studies. Schmorl's nodes were most commonly investigated (n = 99 studies) and defined similarly across studies, with the main difference relating to whether the indentation (node) was required to have a sclerotic margin. There were also similarities in definitions for endplate sclerosis. However, there was great variability in the definitions of other terms, such as lesions, irregularities, abnormalities, erosions and changes., Conclusion: With the possible exception of Schmorl's nodes, we lack a common language for effectively communicating structural endplate findings. This review provides a foundation and impetus for standardizing terminology and core measures to improve communication and synthesis of the growing body of endplate research to advance related knowledge.

This study aimed to establish an effective prognostic nomogram for predicting the probability of postoperative bone remodeling of patients with anterior disc displacement without reduction (ADDWoR). The nomogram was based on a retrospective study on patients underwent surgical approaches for ADDWoR at Shanghai Ninth People's Hospital, Shanghai Jiao Tong University from January, 2007 to January, 2017. A multivariate logistic regression analysis was used to develop variables suitable for probability estimation model. The predictive accuracy and discriminative ability were determined by ROC (AUC-index) and calibration curve. Results were validated using bootstrap resampling with all statistical tests two-sided. 1110 patients were included in the analysis. The probability of postoperative bone remodeling in ADDWoR was 0.51. Six independent prognostic factors including age of onset, nocturnal bruxism, disc morphology, BMD, Wilkes' classification, and postoperative splint therapy were integrated to construct the nomogram. The probability estimation model showed good discrimination in both internal and external validation with AUC-index of 0.84. The calibration curves for probability of postoperative bone remodeling showed optimal agreement with actual observation. In conclusion, a nomogram was established to provide individual prediction of postoperative bone remodeling for patients with ADDWoR treated by arthroscopy surgery.
