Over the past 3 years, the pandemic has caused isolation, mental trauma, stress, financial losses, and various health complications in individuals. Recent reports have stressed the sufferings of the physically abled population. However, we should not neglect the challenges faced by the disabled population, which were more severe in many ways due to their dependency on others at various levels. The strategies implemented to contain the virus have further aggravated their sufferings and made it even worse because health care priorities were skewed toward public-centered care. As a result, it is difficult to determine the extent of care the disabled population received during the pandemic. Moreover, a single-centered study reports that amputations in India increased by 54.1% compared with those during the prepandemic era. This indicates the need for special attention to the physically disabled community, especially persons with movement disabilities. These individuals are partially dependent and have the potential to make significant contributions to the gross domestic product if included in the human resources pool. The Indian government had launched various initiatives to improve their living status. But delays in policy implementation, reduction in budget allocation, and the ongoing pandemic have derailed the efforts. For these reasons, this article emphasizes several challenges in movement disability care. In addition, it makes recommendations for improving the quality of life of persons with movement disabilities. These include collaboration, creating start-up businesses, applying state-of-the-art logistics, establishing a technological ecosystem, raising public awareness, accessing high-quality care, and using contemporary medical devices.</p>","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":"616-622"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71488061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, evidence of construct validity of the Houghton scale was established by the Spearman rho correlation with the Brazilian translation of the Prosthetic Limb Users Survey of Mobility and with the Physical Function (PF) and Emotional Well-being subdomains of the Medical Outcomes Study 36-Short Form Health Survey.</p><p><strong>Results: </strong>Seventy-one volunteers were recruited for the study. The sample consisted mainly of men (70.4%) with a mean age of 50 ± 12 years. The primary cause of amputation was traumatic (53.5%), and most participants (54.9%) had a transtibial amputation. The Houghton questionnaire correlated strongly with the Brazilian translation of the Prosthetic Limb Users Survey of Mobility questionnaire (rho: 0.74, p < 0.01) and weakly with the PF and Emotional Well-being of the 36-Short Form Health Survey (rho: 0.06 and rho: 0.22, respectively, p > 0.05).</p><p><strong>Conclusion: </strong>This study showed evidence of convergent construct validity of the Houghton questionnaire to measure and classify functional use of lower limb prostheses, with great value to clinical practice. Additional work is needed to assess other measurement properties in different samples.</p>","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":"546-550"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139913950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
