Flexion refers to a specific type of movement in which a joint decreases the angle between two connected body parts. For example, when you bend your elbow or knee, you are performing flexion. This action is often measured in degrees to quantify the angle change during movement and helps assess joint function during physical activities.
Understanding flexion is important for health because it plays a critical role in everyday movements such as walking, running, and sitting. Proper flexion can help maintain joint health and mobility, while limited flexion may indicate injury or stiffness in the muscles or joints. Monitoring flexion can be essential in physical therapy and rehabilitation practices to ensure recovery and improve overall physical performance.
In the human body, flexion occurs at various joints, including the knees, elbows, hips, and wrists. Each of these joints allows for different ranges of motion, which are essential for performing daily tasks. For instance, the knee joint's flexion is vital for activities like climbing stairs or squatting. Without adequate flexion, movement becomes restricted, leading to difficulties in mobility and increased risk of injury.
Overall, flexion is a fundamental movement that affects many aspects of physical health and activity. Recognizing its importance helps in understanding body mechanics and the role of joints in facilitating movement.
