Which measurement would suggest a significant limitation in hip flexion?

1. 47 degrees of abduction

2. 10 degrees of extension

3. 129 degrees of flexion

4. 23 degrees of external rotation

The correct answer is: 47 degrees of abduction

The measurement that indicates a significant limitation in hip flexion is 10 degrees of extension. Normal hip flexion is typically measured from a neutral position to how far the hip can flex, which is generally around 120 to 140 degrees in most individuals. When the hip is assessed, a limited extension measurement suggests that the hip is not able to attain the range of motion needed for proper flexion. In the context of the provided choices, a measurement of 10 degrees of extension implies that the individual may not have adequate hip flexion, as the limited extension can restrict the hip's ability to flex fully. This limitation likely affects functional movements and athletic performance, reaffirming that a measurement significantly below a normal range may impair mobility. The other options primarily reflect movements that do not directly measure hip flexion. For instance, 47 degrees of abduction, 129 degrees of flexion, and 23 degrees of external rotation do not suggest inherent limitations in flexion. Instead, they may indicate other aspects of hip joint function that are considered within a range of normal variability.
