RESUMO

OBJECTIVE: To determine the sensitivity and specificity of the clinical diagnostic tests of subacromial impingement syndrome. METHODS: The systematic review comprised search on PubMed, PEDro, Cochrane Library and Google Scholar databases. For prospective cohort studies published in peer-reviewed English-language journals without any time limit, at least fully describing one clinical test. Only studies with free full text available were included. Data extracted included sensitivity and specificity for each clinical test, and variations were sorted out by the 3 reviewers by discussion. RESULTS: Of the 4137 studies identified, 2951(71.3%) were on PubMed, 119(2.9%) PEDro, 5(0.1%) Cochrane Library and 1062(25.7%) Google Scholar. After screening out all the studies that did not match the detailed inclusion criterion, 3(0.07%) studies were selected for review; 1(33.3%) each done in Spain, Turkey and France. Overall, there were 181 aged 15-82 years; 85(47%) males and 96(53%) females. Supraspinatus palpation test had a sensitivity of 92%, while the modified Neer test had specificity of 95.56% in terms of ruling out subacromial impingement syndrome. CONCLUSIONS: Supraspinatus palpation and modified Neer tests were found to be the most effective in the diagnosis of subacromial impingement syndrome.

RESUMO

Cellulose is world's most abundant, renewable and recyclable polysaccharide on earth. Cellulose is composed of both amorphous and crystalline regions. Cellulose nanocrystals (CNCs) are extracted from crystalline region of cellulose. The most attractive feature of CNC is that it can be used as nanofiller to reinforce several synthetic and natural polymers. In this article, a comprehensive overview of modification of several natural and synthetic polymers using CNCs as reinforcer in respective polymer matrix is given. The immense activities of CNCs are successfully utilized to enhance the mechanical properties and to broaden the field of application of respective polymer. All the technical scientific issues have been discussed highlighting the recent advancement in biomedical and packaging field.
