musculoskeletal objectives Flashcards
Abduction
Moving a limb away from the midline of the body.
Adduction
Moving a limb toward the midline of the body.
Extension
Straightening a limb at a joint, increasing the angle between bones.
Flexion
Bending a limb at a joint, decreasing the angle between bones.
Rotation
Moving a body part around its axis (e.g., turning the head side-to-side).
Plantarflexion
Pointing the toes downward, like pressing a gas pedal.
Dorsiflexion
Pulling the foot upward, opposite of plantarflexion.
What is the TMJ?
The articulation between the mandible and temporal bone.
Where can the TMJ be felt?
In the depression anterior to the tragus of the ear.
What functions does the TMJ permit?
Speaking and chewing.
What are the three motions of the TMJ?
- Hinge action (open and close jaws)
- Gliding action (protrusion and retraction)
- Gliding side-to-side movement.
What should be assessed during TMJ palpation?
Crepitus (crackling sound) or pain with motion or palpation.
What is the purpose of both Phalen and Tinel tests?
To assess for carpal tunnel syndrome by evaluating the function of the median nerve.
How is the Phalen test performed?
Ask the person to hold both hands back-to-back while flexing the wrists to 90 degrees for 60 seconds.
What is a normal Phalen test result?
No symptoms (numbness or tingling) in the hand.
How is the Tinel sign performed?
Tap (percuss) directly over the median nerve at the wrist.
What is a normal Tinel sign result?
No symptoms (tingling or pain) are felt when percussing the nerve.
What is a positive result for either test?
Tingling, numbness, or pain over the median nerve distribution (thumb, index, middle, and part of the ring finger).
What do positive Phalen and Tinel tests indicate?
Both suggest carpal tunnel syndrome.
How do the tests differ?
Phalen test assesses symptoms after prolonged wrist flexion, while Tinel sign identifies irritability of the median nerve by direct percussion.
What is Genu Varum?
A condition where the legs curve outward, creating a bow-legged appearance: _ _/.
What is Genu Valgum?
A condition where the knees come inward, creating a knock-kneed appearance: _/ _. The Disknees
What are non-synovial joints?
Joints where bones are united by fibrous tissue or cartilage.
What are examples of non-synovial joints?
Immovable: Skull sutures
Slightly movable: Vertebrae.
What are synovial joints?
Joints where bones are separated by a joint cavity and enclosed, allowing free movement.
What fills the joint cavity in synovial joints?
Synovial fluid, which lubricates the joint for smooth movement.
Example of a synovial joint?
The knee joint.
