Frozen shoulder (FS) rarely occurs before age 40 and typically affects ages 50 to 70. Women are more commonly affected than men. Frozen shoulder is classified into primary and secondary, where primary frozen shoulder is due to the presence of attachments around the joint capsule and secondary frozen shoulder is due to sprains, strains, tendinopathy, tendon tear or bursitis. This study, conducted at Mutiara Sukma Mental Hospital NTB in September-October 2022, aimed to evaluate the effectiveness of physiotherapy interventions on a 64-year-old patient with frozen shoulder, mental disorders, and diabetes, using a case study approach. Interventions included Infrared therapy and TENS (Transcutaneous Electrical Nerve Stimulation) for pain reduction and muscle relaxation, as well as Neuromuscular Taping (NMT) for enhanced lymphatic drainage and pain relief. Assisted active movements and free active movements were also applied to maintain and improve joint range of motion and muscle strength. The results showed significant improvements in pain reduction and increased range of motion and shoulder function, with pain evaluation using the Numerical Rating Scale (NRS) and Shoulder Pain and Disability Index (SPADI) indicating positive progress during therapy sessions. This underscores the benefits of combined physiotherapy interventions in treating frozen shoulder, especially in patients with comorbid mental disorders.","PeriodicalId":19392,"journal":{"name":"Nucleus","volume":"1 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139273082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To find out in detail the existing problems, a business process analysis is needed which is outlined in the picture. The method used is field observation, while the tools used are BPMN (Business Process Modeling Notation). The result of this research is a model that describes business processes with standard notation that is easy to understand. With this model, it will be able to display the availability of raw materials, both incoming raw materials and outgoing raw materials, as well as overall raw material availability reports.
