Clinical Biomechanics Practice Test 2026 – Comprehensive Exam Prep

The term that refers to any degree of relaxation away from the close packed position is "open packed." The concept of open packed refers to a joint position that allows for more movement and flexibility compared to a close packed position, where the joint surfaces are maximally congruent and provide stability.

In an open packed position, the ligaments and capsule are less taut, allowing for greater ranges of motion and accessibility for movement. This is important in biomechanics as it facilitates activities such as stretching and joint mobilization. Understanding the difference between open packed and close packed positions is crucial in clinical settings, as it influences rehabilitation and the treatment of musculoskeletal conditions.
