However, the lower extremities are prone to deep vein thrombosis (DVT) and swelling after surgery, thereby delaying recovery. In this study, we investigated the preventive effects of fondaparinux sodium (FS) and low-molecular-weight heparin (LMWH) on DVT of the lower extremity after THA.Methods: Firstly, 60 patients who underwent THA at the First Affiliated Hospital of Wannan Medical College from March 2020 to December 2020 were included. Next, the patients were randomly divided into an LMWH group (n = 30) and an FS group (n = 30). Then, the indexes related to DVT were compared between both groups.Results: Specifically, the differences in baseline data, such as age, gender and body mass index (BMI), between the two groups were not statistically significant. The postoperative weight bearing time of patients in the FS group was much shorter than that in the LMWH group.Conclusion: Subcutaneous injection of FS not only exhibits superior effects to LMWH in preventing DVT after THA but also has a correlation with reducing the risk of thrombosis and improving patient symptoms.","PeriodicalId":16430,"journal":{"name":"Journal of musculoskeletal & neuronal interactions","volume":"24 2","pages":"185-191"},"PeriodicalIF":1.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11145315/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141199829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrodiagnostic (EDX) testing is considered the gold standard for CTS diagnosis. Classification systems exist that categorize CTS severity based on EDX findings. This investigation evaluated EDX findings across consecutive CTS severity categories within existing classification systems and consolidated classifications.Methods: This retrospective study analyzed 665 hands from 468 patients undergoing EDX testing for suspected CTS. Complete classification systems and consolidated classifications were evaluated for discrimination capability across consecutive CTS severity categories based on EDX findings. Additional analysis evaluated the relationship of sex and age factors and CTS severity.Results: Consolidated classifications demonstrated superior discrimination capability between consecutive CTS severity categories regardless of classification system used. Demographic factors significantly influenced EDX findings and categorization of CTS severity.Conclusions: This study underscores the value of consolidated classifications for enhancing discrimination between consecutive CTS severity categories based on EDX findings. Demographic factors should be considered when interpreting EDX findings for the purpose of categorizing CTS severity. Future research should refine existing classification systems and explore additional factors influencing CTS severity used to inform medical management.","PeriodicalId":16430,"journal":{"name":"Journal of musculoskeletal & neuronal interactions","volume":"24 2","pages":"216-227"},"PeriodicalIF":1.9,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11145321/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141199822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated whether motor unit (MU) recruitment and firing property, which are important for muscle exertion, have altered in serratus anterior of the individuals with scapular dyskinesis.Methods: Asymptomatic adults with (SD) and without (control) scapular dyskinesis were analyzed. Surface electromyography (sEMG) waveforms were collected at submaximal voluntary contraction of the serratus anterior. The sEMG waveform was decomposed into MU action potential amplitude (MUAPAMP), mean firing rate (MFR), and recruitment threshold. MUs were divided into low, moderate, and high thresholds, and MU recruitment and firing properties of the groups were compared.Results: High-threshold MUAPAMP was significantly smaller in the SD group than in the control group. The control group also exhibited recruitment properties that reflected the size principle, however, the SD group did not. Furthermore, the SD group had a lower MFR than the control group.Conclusions: Individuals with scapular dyskinesis exhibit altered MU recruitment properties and lower firing rates of the serratus anterior; this may be detrimental to muscle performance.
