In assessing normal range of motion, what is the typical limit for wrist extension?

The typical limit for wrist extension is indeed 70-80 degrees. This range reflects the normal anatomical limits of the wrist joint, which is crucial for various functional tasks involving the hand and arm.

Understanding the normal range of motion is essential for clinicians in order to assess joint function accurately. A wrist extension of 70-80 degrees allows for optimal wrist mobility and contributes to effective hand positioning for activities such as grasping and manipulating objects.

This specific range also provides a benchmark against which deviations from normal can be measured, allowing healthcare professionals to identify potential limitations or pathologies that may affect a patient's functional abilities. Assessing and maintaining this range is particularly important in rehabilitation settings, where restoring full wrist function can significantly impact a person's quality of life and independence.
