<P> Palpation is the process of using one's hands to examine the body, especially while perceiving / diagnosing a disease or illness . Usually performed by a health care practitioner, it is the process of feeling an object in or on the body to determine its size, shape, firmness, or location (for example, a veterinarian can feel the stomach of a pregnant animal to ensure good health and successful delivery). </P> <P> Palpation is an important part of the physical examination; the sense of touch is just as important in this examination as the sense of sight is . Physicians develop great skill in palpating problems below the surface of the body, becoming able to detect things that untrained persons would not . Mastery of anatomy and much practice are required to achieve a high level of skill . The concept of being able to detect or notice subtle tactile signs and to recognize their significance or implications is called appreciating them (just as in general vocabulary one can speak of appreciating the importance of something). Nonetheless, some things are not palpable, which is why additional medical tests, such as medical imaging and laboratory tests, are often needed to make a diagnosis . However, many other problems are palpable . Examples include pulses, abdominal distension, cardiac thrills, fremitus, and various hernias, joint dislocations, bone fractures, and tumors, among others . </P> <P> Palpation is used by physicians, as well as chiropractors, massage therapists, physical therapists, osteopaths and occupational therapists, to assess the texture of a patient's tissue (such as swelling or muscle tone), to locate the spatial coordinates of particular anatomical landmarks (e.g., to assess range and quality of joint motion), and assess tenderness through tissue deformation (e.g. provoking pain with pressure or stretching). In summary, palpation might be used either to determine painful areas and to qualify pain felt by patients, or to locate three - dimensional coordinates of anatomical landmarks to quantify some aspects of the palpated subject . </P> <P> Palpation is typically used for thoracic and abdominal examinations, but can also be used to diagnose edema and to measure the pulse . It is used by veterinarians to check animals for pregnancy, and by midwives to determine the position of a fetus . </P>
