What is the primary purpose of performing range-of-motion exercises?

1. To tire the resident

2. To improve circulation and flexibility

3. To restrict movement for recovery

4. To reduce the need for physical therapy

The correct answer is: To improve circulation and flexibility

The primary purpose of performing range-of-motion exercises is to improve circulation and flexibility. These exercises help maintain or enhance the mobility of the joints, which is essential for overall physical functioning. By encouraging movement through the full extent of joint motion, these exercises promote better blood flow, reduce stiffness, and prevent the loss of muscle strength. Improved circulation is particularly important for residents who may be less mobile due to illness or disability, as it can aid in the distribution of nutrients and the removal of waste products from the tissues. Enhancing flexibility through range-of-motion exercises also aids in preventing injuries and maintaining a higher quality of life for individuals. This is especially crucial for those at risk of developing conditions such as contractures, which can result from prolonged inactivity. By regularly performing these exercises, caregivers can support their residents' physical health and well-being.
