7 Essential NPTE Study Tips for Understanding Open vs Closed Packed Positions
· based on the channel Typical PT
Key takeaways
- Open packed position is also known as loose packed position with maximum joint play.
- Closed packed position features maximum joint congruency and ligament tension, providing joint stability.
- Open packed vs closed packed positions differ in joint stability and congruency essential for NPTE questions.
- Recognizing terminology and joint positions improves accuracy on NPTE musculoskeletal questions.
- Typical PT channel offers targeted NPTE study strategies for orthopedic and joint positions.
Understanding Open and Closed Packed Positions for NPTE Success
Open packed and closed packed positions are critical concepts in NPTE musculoskeletal questions. Open packed position, also called loose packed position, refers to the joint position where there is the greatest amount of joint play and minimal ligament tension. In contrast, closed packed position is where the joint surfaces are maximally congruent, ligaments are taut, and the joint is most stable. Knowing these differences helps you quickly identify correct answers on the NPTE.

1. Define Open Packed Position Clearly
The open packed position is the position of a joint where the joint capsule and ligaments are lax, allowing the greatest freedom of movement and joint play. For example, the knee’s open packed position is about 25 degrees of flexion, where the joint surfaces are not fully congruent. This position is important for joint mobilization techniques and is often tested in NPTE musculoskeletal questions to assess your understanding of joint mechanics.
2. Recognize Closed Packed Position Characteristics
Closed packed position is when the joint surfaces fit together perfectly, ligaments are tight, and the joint is mechanically stable. For instance, full knee extension is the closed packed position for the knee joint. This position limits joint play and is commonly referenced in NPTE questions related to joint stability and injury mechanisms.
3. Compare Open vs Closed Packed Positions
Key differences include:
- Open packed allows maximal joint play; closed packed allows minimal.
- Open packed has loose ligaments; closed packed has taut ligaments.
- Open packed is less stable; closed packed is the most stable joint position.
- Understanding these contrasts helps in distinguishing scenarios described in NPTE orthopedic questions.
4. Apply Joint Position Knowledge to NPTE Musculoskeletal Questions
Many NPTE questions require you to identify which joint position is being described or which position is optimal for treatment techniques like mobilizations. Knowing that open packed positions are used for joint play and mobilization, while closed packed positions are for joint stability, will guide your answers.
5. Use Terminology Clues to Answer Questions Efficiently
NPTE questions often use terms like "maximum congruency," "ligament tension," or "joint play." Recognizing these phrases helps you link them to closed or open packed positions without hesitation. Practice with NPTE-style questions to familiarize yourself with this language.
6. Memorize Common Joint Positions for Major Joints
Some common open and closed packed positions include:
- Shoulder: Open packed at 55° abduction and 30° horizontal adduction; closed packed at full abduction and external rotation.
- Elbow: Open packed at 70° flexion and 10° supination; closed packed at full extension.
- Wrist: Open packed at neutral with slight ulnar deviation; closed packed at full extension.
- Memorizing these specific positions enhances your recall during the exam.

Questions & answers
What is the difference between open packed and closed packed joint positions?
Open packed position is where the joint capsule and ligaments are lax, allowing maximum joint play, while closed packed position features maximum joint congruency and ligament tension, resulting in joint stability.
Why is it important to know open and closed packed positions for the NPTE?
Understanding these positions helps you answer musculoskeletal questions accurately, especially those related to joint stability, mobility, and orthopedic treatment techniques.
Can you give an example of an open packed position in a major joint?
Yes, for the knee joint, the open packed position is approximately 25 degrees of flexion, where the joint surfaces have maximal play and minimal ligament tension.
How can I best prepare for NPTE questions on joint positions?
Practice recognizing terminology clues in questions, memorize common open and closed packed positions for major joints, and use study materials like those from Typical PT for targeted review and practice.
