Increasing the range of motion at joints by using both active and passive stretching is known as:

The process of increasing the range of motion at joints through a combination of active and passive stretching is best described by proprioceptive neuromuscular facilitation, commonly referred to as PNF stretching. This technique involves both stretching and contracting the muscle group being targeted. The active component is where the individual actively engages the muscle, while passive elements can involve a partner or an external force to assist in the stretch. This combination is effective in enhancing flexibility and improving overall joint mobility, making it a valuable method in rehabilitation and athletic training.

In contrast to PNF stretching, dynamic stretching entails moving parts of the body through a full range of motion in a controlled manner, often used as part of a warm-up routine. Isometric stretching focuses on muscle contractions without changing the muscle length, which does not significantly increase the range of motion. Ballistic stretching involves bouncing or jerking movements to force the muscle beyond its normal range, which can lead to injury if not done carefully. These differences underscore why PNF stretching is the correct term for the described method.
