Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependentupon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicularseparation with several static and dynamic operative procedures with or without primary ligament replacement.Methods: 47 patients with acute Rockwood type III, IV, an...

Wind tunnel to Atmospheric Mapping (WAM) is a methodology for scaling and testing a static aeroelastic wind tunnel model. The WAM procedure employs scaling laws to define a wind tunnel model and wind tunnel test points such that the static aeroelastic flight test data and wind tunnel data will be correlated throughout the test envelopes. This methodology extends the notion that a single test co...

background: to validate the persian version of the simple shoulder test in patients with shoulder joint problems.   methods: following beaton`s guideline, translation and back translation was conducted. we reached to a consensus on the persian version of sst. to test the face validity in a pilot study, the persian sst was administered to 20 individuals with shoulder joint conditions. we enrolle...

Identifying loads that maximize mechanical power is important because training at such loads may optimize gains in dynamic athletic performance. The purpose of this study was to examine correlations between measures of external mechanical power output and internal mechanical joint power output across different loads during a weightlifting exercise. Ten subjects performed 3 sets of the clean exe...

Broad allometric studies of the musculoskeletal system have frequently sought to explain how locomotor variables have been influenced by body mass. To examine animals that vary widely in body mass, these studies have included taxa that differ in their locomotor adaptations and phylogenetic relatedness. Because these sources of diversity could obscure the effects of body mass, this study was des...

background: the optimal position of the condyle in glenoid fossa is a fundamental question in dentistry. there is no quantitative standard for the optimal position of mandibular condyle in the glenoid fossa in our population. the purpose of this study is to assess the position of the condyle by cone beam computed tomography (cbct) images in patient with normal function of temporomandibular join...
