Flashcards

Peripheral Joint Mobilization

Manual therapy technique used to improve joint movement and reduce pain by manipulating the joint capsule, ligaments and surrounding tissues.

Open Pack Position

Joint position where the joint capsule and ligaments are most relaxed, allowing easier movement and reducing stress on the tissues.

Grade I Joint Mobilization

Small amplitude oscillatory movements at the beginning of the joint's range of motion.

Grade II Joint Mobilization

Large amplitude oscillatory movements in the middle of the joint's range of motion, stopping before major tissue restriction.

Mobilization with Stretch vs. Passive Stretch

Mobilization with stretch combines joint mobilization with a stretch, targeting restrictions and increasing range more efficiently. Passive stretches only lengthen soft tissue.

Study Notes

Peripheral Joint Mobilization Advantages

  • Mobilization with stretching is more beneficial than passive stretching alone.

Terminology

  • Caudal: Located towards the tail end.
  • Dorsal: Located on the back.
  • Volar: Located on the palm side (hand) or sole (foot).

Open Pack Positions

  • Shoulder:
    • Abduction (Abd) 55 degrees, Horizontal Adduction (H Add) 30 degrees (in the plane of the scapula).
    • Convex-humerus, concave-glenoid.
  • Hip:
    • Flexion (Flx) 30 degrees, Abduction 30 degrees, slight External Rotation (ER).
    • Convex-femur, concave-acetabulum.
  • Knee (patello-femoral):
    • Extension
    • Convex-patella, concave-tibia.
  • Knee (tibio-femoral):
    • Flexion (Flx) 25 degrees.
    • Convex-femur, concave-tibia.
  • Ankle:
    • Plantar Flexion (PF) 10 degrees.
    • Convex-talus, concave-tibia and fibula.

Grade I-IV Mobilization

  • Grade I:
    • Small amplitude oscillatory movement at the beginning of the range of motion.
  • Grade II:
    • Larger amplitude oscillatory movement in the mid-range of motion. Does not reach the first restriction.
  • Grade III:
    • Large amplitude oscillatory movement from the mid-range to end range, into tissue resistance.
  • Grade IV:
    • Small amplitude oscillatory movement at the end range of motion.
  • Grade I and II Benefits:
    • Primarily for pain modulation.
    • Unloads and decompresses.
    • Often used with stretching.
    • Stimulates synovial fluid to nourish cartilage.
    • Maintains joint play in the face of limited ROM and often used as the first treatment to understand joint restrictions (Grade II).
  • Grade III and IV Benefits:
    • Used to increase range of motion.
    • Stretches joint structures and increases joint play.
