Joint Motion Concepts and Terminology Flashcards

1
Q

What is Osteokinematic Motion?

A

Directions the bones move when motion occurs
AKA: “Physiologic Motions”
-Visible motion during voluntary movement
- Typically described as movement around a specific joint axis and within a particular joint plane

Q

What is Arthokinematic motion?

A

motion between the joint surfaces during movement
AKA “accessory motions or joint play”
- The motion that should occur within the joint to allow normal range of motion (osteokinematic) to occur
- Invisible and involuntary

Q

What is the Convex on Concave rule?

A

Convex surface moving on fixed concave surface: Roll and Glide accessory motions occur in the OPPOSITE direction
- Movement of bone is in OPPOSITE direction to movement of joint (glide)

Q

What is the Concave on Convex rule?

A

Concave surface moving on fixed convex surface:
Roll and glide accessory motions occur in the SAME direction
- Movement of the bone is in the same direction as movement of joint surface

14
Q

What is Open- Packed (loose)?

A
  • Ligaments and capsule in position of greatest laxity
  • joint surfaces are maximally separated
  • Minimal congruency between joint surface
  • Proper position to assess joint play and to mobilize

Q

What is Close- Packed position?

A
  • Ligaments and capsule are taut
  • Joint surfaces are maximally contacted
  • Maximal congruency between joint surface
  • Position of maximal stability
  • POOR position to assess joint play or to mobilize.

Q

What is End- Feel?

A

The sensation you “Feel” in the joint as it reaches the end of the range of motion

  • it assesses the quality of motion
  • Assists in identifying pathology
17
Q

What are “normal” End- feels?

A

Bone to bone, Soft- Tissue approximation, and Tissue Stretch

18
Q

What is bone to bone end feel?

A

Hard, unyielding sensation; painless

Example: Elbow Extension

19
Q

What is soft tissue approximation?

A

Soft, yielding compression

Example: Muscle contact with elbow or knee flexion

20
Q

What is Tissue stretch?

A

Hard or firm (springy) type of movement with a slight give
- Feeling of springy or elastic resistance
Example: Shoulder rotation, knee extension

21
Q

What are abnormal end feels?

A

Capsular (hard and soft capsular), Muscle Spasm, and Bone to bone, springy block, empty

22
Q

What is capsular end feel?

A

Similar to tissue stretch, but occurs early in motion. There are two subdivisions (Hard and Soft)

23
Q

What is Hard Capsular End feel?

A

Hard or firm end feel, thicker feeling than normal tissue stretch

  • Abrupt onset after smooth, friction- free movement
  • Seen in chronic conditions
24
Q

What is Soft Capsular End feel?

A

Boggy, very soft, mushy end feel typically accompanied joint effusion

  • Stiffness early in range and increases until end range
  • Seen in acute conditions
25
Q

What is an abnormal muscle spasm end feel?

A

Sudden and hard end feel; dramatic arrest in movement accompanied with pain; usually due to subconscious effort to protect an injured joint or structure

26
Q

What is bone to bone abnormal end feel?

A

Hard, unyielding sensation similar to normal bone to bone
-Restriction occurs before normal end range is expected
Example: Osteophyte formation

27
Q

What is Springy Block abnormal end feel?

A

Also a firm end feel, similar to tissue stretch

  • Restriction occurs before normal end range is expected
  • Usually has a rebound effect indicating internal derangement in the joint (i.e., meniscal tear)
28
Q

What is empty abnormal end feel?

A

No mechanical resistance, but considerable pain is produced by movement

29
Q

What is a capsular pattern?

A

characteristic pattern of motion restriction when joint capsule is involved (contracted)

  • Unique pattern for each joint
  • Often inconsistent, but may be helpful

Examples: Glenohumeral joint: ER limited more than ABD, limited more than IR
Hip- FLEX limited more than ABD, limited more than IR
