Differential Diagnosis and Medical Screening


Screening for the presence of disease has always been an important part of a comprehensive physical therapy evaluation. However, in this era of direct access to patients, a general knowledge of various disease processes and knowing when to refer a patient to their physician for further evaluation and testing is critically important. In fact, many states and medical insurance companies require that physical therapists who see patients directly, attend continuing education coursework in Differential Diagnosis evaluation techniques. One of the goals of the APTAs Vision 2020 is that every state in the US will enact Direct Access legislation by the year 2020. This course will increase your confidence and ability to evaluate and treat patients independently. Differential Diagnosis and Medical Screening: Essentials for Direct Access covers the various elements that must be considered in the Medical Screening of patients, including components of a comprehensive medical history, Red Flag signs and symptoms for the various body regions, research findings on clinical predictive rules for various orthopedic complaints, and provides an overview of pharmacology and imaging studies. Lab components will focus on UE and LE neural tension testing, special diagnostic tests for spine and extremity orthopedic conditions, and heart/lung/abdominal screening examinations. This intermediate level course is designed for and is taught by practicing clinicians. As such the subject matter was chosen for clinical relevance, as opposed to being presented from an academic or purely medical perspective. It contains information useful for therapists in any practice setting where patients with multiple medical conditions and/or medications are encountered, such as hospitals, nursing homes, home care, and outpatient clinics with complex orthopedic and neurologic caseloads. The provided course book includes the powerpoint slides used in this presentation, a Medical History questionnaire template, and concludes with a series of patient case studies designed to bring together the various components covered in the course. This course will provide therapists with a solid foundation in differential diagnosis, which is crucial when dealing with complex patient issues and when seeing patients as the primary care provider.
