This may enable more children to receive assistance before experiencing significant failure, which may, in turn, result in fewer children who need intensive and expensive special education services. In the United States, the 2004 reauthorization of the Individuals with Disabilities Education Act permitted states and school districts to use RTI as a method of identifying students with learning disabilities. RTI is now the primary means of identification of learning disabilities in Florida. The process does not take into account childrens individual neuropsychological factors such as phonological awareness and memory, that can inform design instruction. By not taking into account specific cognitive processes, RTI fails to inform educators about a students relative strengths and weaknesses Second, RTI by design takes considerably longer than established techniques, often many months to find an appropriate tier of intervention. Third, it requires a strong intervention program before students can be identified with a learning disability. Lastly, RTI is considered a regular education initiative and consists of members of general education teachers, in conjunction with other qualified professionals. Occupational therapists (OTs) in particular can support students in the educational setting by helping children in academic and non-academic areas of school including the classroom, recess and meal time. They can provide strategies, therapeutic interventions, suggestions for adaptive equipment, and environmental modifications. OTs can work closely with the childs teacher and parents to facilitate educational goals specific to each child under an RTI and/or IEP.
The best response to fibrinolytic drugs is within a couple of hours, before the fibrin meshwork of the thrombus has been fully developed. Organization and recanalization involves the ingrowth of smooth muscle cells, fibroblasts and endothelium into the fibrin-rich thrombus. If recanalization proceeds it provides capillary-sized channels through the thrombus for continuity of blood flow through the entire thrombus but may not restore sufficient blood flow for the metabolic needs of the downstream tissue.
