Käsialueet

Käsialueet refers to a concept in Finnish that translates to "hand areas" or "palmar regions." In the context of medicine and anatomy, it specifically denotes the parts of the hand that are in contact with a surface when the palm is placed flat. This typically includes the palm itself, the thenar eminence (the fleshy part at the base of the thumb), and the hypothenar eminence (the fleshy part at the base of the little finger).

The term is often used in discussions related to physical examinations, ergonomics, and the assessment of hand function. For instance, a doctor might ask a patient to place their hands flat to assess grip strength or to identify areas of pain or swelling. In ergonomics, understanding the contact areas of the hand is crucial for designing tools, workstations, and protective equipment that minimize strain and prevent injuries.

The surface area covered by the käsialueet can vary depending on the size and position of the hand. Factors such as age, sex, and individual anatomy can influence these dimensions. Understanding these areas is also relevant in fields like physiotherapy and occupational therapy, where specific exercises or treatments might target these regions to improve mobility, strength, or sensation.
