In index MCP anterior/volar glide joint mobilization, what is the loose-packed position of the MCP joint?

Explanation:
The main idea is that the loose-packed (resting) position of a joint is where the capsule and ligaments are most lax, allowing the greatest ease of movement and access for gliding. For the metacarpophalangeal joints, this lax position occurs at about 20 degrees of flexion. At this angle the joint surfaces are not held tightly together, so accessory glides—like the anterior/volar glide used to improve flexion—can occur with less resistance. In contrast, near-full extension tightens the capsule and ligaments, creating a more stable, closed-packed situation that limits glide. So, the index MCP joint’s loose-packed position is roughly 20 degrees of flexion.
