Development of Normative Ultrasound Databases of Tongue Surface Configuration Clinical Trials Information presented on Clinical Trials Search isn't designed to be a substitute for certified healthcare advice, travels to or professional assistance using a genuine medical doctor. We are not physicians. Always confer with your dr. about Development of Normative Ultrasound Databases of Tongue Surface Configuration conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Development of Normative Ultrasound Databases of Tongue Surface Configuration Clinical research trials and Development of Normative Ultrasound Databases of Tongue Surface Configuration medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as Development of Normative Ultrasound Databases of Tongue Surface Configuration. Development of Normative Ultrasound Databases of Tongue Surface Configuration Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a Development of Normative Ultrasound Databases of Tongue Surface Configuration clinical trial. Participants frequently get the best healthcare available for their Development of Normative Ultrasound Databases of Tongue Surface Configuration condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

Development of Normative Ultrasound Databases of Tongue Surface Configuration



Development of Normative Ultrasound Databases of Tongue Surface Configuration

For Condition: Healthy,Speech Disorders
Status: Completed
Sponsor(s): Warren G Magnuson Clinical Center (CC) ,
Synopsis: Our past ultrasound research has indicated a need for baseline normative tongue data against which to compare our disordered speech populations. Subjects with normal speech and hearing who represent different ages and sexes, will be studied with respect to tongue shape and movement patterns. Recently developed parameters such as curve fitting, curve averaging, and polar coordinates will be used to create baseline data categories. In addition, new parameters and improved instruments will be developed as previously to produce a data base which can be used across disciplines.
