Objective To study the correlation between the cervical posture in the cervical disc replacement (CDR) and the cervical curve restoration in neutral position after surgery. Methods Between January 2008 and August 2010, 51 patients underwent single segmental PRESTIGE LP replacement, and the clinical data were retrospectively analyzed. During the surgery, the patient was supinely placed and the lordosis of the cervical spine was mantained with a pillow placed beneath the neck. Of them, 28 were male and 23 were female, aged 30-64 years (mean, 45 years); 32 were diagnosed as having cervical spondylotic myelopathy, 7 having radiculopathy, and 12 having myelopathy and radiculopathy. The disease duration was 3-48 months (mean, 15 months). CDR was performed at C4, 5 in 5 cases, at C5, 6 in 42 cases, and at C6, 7 in 4 cases. The Cobb angles of the cervical alignment, targeted functional spinal unit (FSU), and targeted disc were measured by sagittal X-ray film of the cervical spine in neutral position before and after surgery, as well as the intraoperative C-arm fluroscopy of the cervical spine. Linear correlation and regression were performed to analyze the relation between cervical Cobb angle difference at intraoperation and improvement of the Cobb angles at 3 months after operation. Results The cervical Cobb angles at intraoperation and 3 months after operation were larger than those at preoperation (P lt; 0.05). The difference of the Cobb angle between intra- and pre-operation was (6.72 ± 9.13)° on cervical alignment, (2.10 ± 5.12)° on targeted FSU, and (3.33 ± 3.75)° on targeted disc. At 3 months after operation, the Cobb angle improvement of the cervical alignment, targeted FSU, and targeted disc was (6.30 ± 7.28), (3.99 ± 5.37), and (4.29 ± 5.36)°, respectively. There was no significant difference in the Cobb angle improvement between the targeted FSU and the targeted disc (t= — 0.391, P=0.698), and between the targeted disc and the cervical alignment (t= — 1.917, P=0.061), but significant difference was found between the targeted FSU and the cervical alignment (t= — 2.623, P=0.012). The linear correlation between the Cobb angle difference and the Cobb angle improvement of the cervical spine was observed (P lt; 0.05). Conclusion A slightly lordotic cervical posture during CDR is an important factor to maintaining normal physiological lordosis of the cervical spine after surgery.
Pusher syndrome (PS) is a postural control disorder that occurs after stroke, which is mainly manifested as a balance dysfunction that is difficult to correct, leading to a significant decline in activity safety of stroke patients and hindering the process of rehabilitation treatment. Proper interventions are needed as soon as possible. Based on the research results of PS both domestic and foreign, this paper firstly summarizes the foundations of the mechanism of PS occurrence, and elaborates the existing disputes. Secondly, this paper systematically introduces the current mainstream assessment and treatment methods of PS, summarizes the problems in relevant clinical practice, and on this basis, gives some suggestions on the possible research directions in the future. The purpose is to provide reference for clinical application and future research directions.
Objective To summarize the best evidence for posture management in children and adolescents with neurodevelopmental disorders, and to provide an evidence-based reference for clinical posture management, musculoskeletal deformity prevention and functional outcome improvement. Methods The evidence-based question was formulated using the PIPOST framework. A systematic search was performed following the 6S evidence model in UpToDate, BMJ Best Practice, Web of Science, Cochrane Library, PubMed, CNKI, CBM, VIP and Wanfang Data, from January 2021 to May 2026. ResultsA total of 35 articles were included, consisting of 5 guidelines, 20 systematic reviews/Meta-analyses, 8 randomized controlled trials and 2 expert consensuses. Twelve pieces of best evidence were extracted across 6 domains: 24-hour posture management, disease-specific interventions, assessment tools, stratified functional intervention, nighttime postural support and emerging technologies. ConclusionThe summarized best evidence for posture management in children and adolescents with neurodevelopmental disorders helps standardize clinical postural interventions, reduce the risk of musculoskeletal deformities, and support stratified, individualized rehabilitation management.
