Lecture on Joint Positions in Therapy

Introduction

• Discussion on joint positions and their implications in therapy.
• Mention of resources: assessment ebook and mobile app.

Key Joint Positions

Close-Packed Position (CPP)

• Definition: Occurs at one extreme of joint movements.
• Characteristics:
  • Concave surface is in complete congruence with the convex surface.
  • Capsule and ligaments are under maximal tension.
  • Joint surfaces are tightly compressed.
  • Most stable joint position; minimal room inside the joint.
  • Joint cannot be separated by traction.
• Use in Therapy:
  • Joint mobilizations cannot be performed in this position.
  • Useful for fixing a joint to move an adjacent joint (e.g., hip in CPP for SI joint examination).

Maximum Loose-Packed Position (MLPP)

• Definition: Exact opposite of the close-packed position.
• Characteristics:
  • Joint under least stress; capsule most relaxed.
  • Minimal congruence and contact between articular surfaces.
  • Maximum space inside the joint; optimal joint lubrication.
  • Bones can be drawn apart by traction.
• Clinical Relevance:
  • Preferred by patients with serious inflammation.
  • Used to assess joint play, traction, mobilizations, and manipulations.

Resting Position

• Definition: Position where all muscles crossing the joint are maximally relaxed.
• Note: Different from MLPP.

Importance for Physiotherapists

• CPP and MLPP Knowledge:
  • Crucial for effective joint mobilizations and manipulations.
  • Different positions stress different parts of the joint capsule.

Resources & Further Learning

• A table overview of CPP and MLPP for various joints (available via download link).
• Additional video recommendation:
  • Understanding joint capsule stress in different positions using the concave-convex rule.

Conclusion

• Encouragement to utilize and benefit from the video content in professional practice.
• Call to action: Like, comment, subscribe, and connect on social media platforms (Facebook, Instagram, physio tutors).

This summary captures the essential points regarding joint positions in therapy and their practical implications for physiotherapists. The distinction and understanding of different joint positions like CPP and MLPP are pivotal for proper assessment and treatment.
