palpaatsioon

Palpation is a fundamental diagnostic method used in medicine and various other fields, involving the examination of the body by touch. It is a systematic process where a trained individual uses their hands and fingers to assess the size, consistency, texture, temperature, moisture, location, and movement of body parts, tissues, or organs. This technique is crucial for detecting abnormalities, such as lumps, swelling, tenderness, or changes in normal anatomical structures.

In medicine, palpation is a core component of the physical examination. Doctors use it to feel for pulses, assess muscle tone, identify enlarged organs, detect hernias, and evaluate the condition of joints and bones. The pressure applied during palpation is carefully controlled to avoid causing pain or discomfort to the patient while still gathering sufficient information. Different parts of the hand and fingers may be used depending on the specific assessment being performed. For instance, the fingertips are sensitive for detecting fine details, while the palm can be used for broader assessments of swelling or vibration.

Beyond healthcare, palpation finds applications in fields like massage therapy, physical therapy, veterinary medicine, and even in some crafts where tactile feedback is essential for quality control or understanding material properties. The effectiveness of palpation relies heavily on the practitioner's experience, training, and sensory acuity, as well as their knowledge of normal anatomy and physiology.
