Goniometry (Knee and Ankle) Flashcards
Knee goniometer alignment

- Dist. Arm: lateral malleolus
Knee Flexion ROM
0-130/140º
Knee Extension ROM

*(0-5/10º in children)
Knee Flexion positioning and stablization
- Supine with a towel under ankles
- Bring leg up to 90º hip flexion
- Hold hip position with one hand and flex lower leg toward butt.
- Stabilize the femur
Knee flexion end feel
(End Feel is soft but might be firm because of tension in quad muscles)
Knee extension positioning and stabilization
- Measured at starting position of knee flexion
- Stabilize the femur
Knee extension end feel
Firm
Ankle goniometer alignment for flexion

- Prox. Arm: head of fibula, using lateral midline
- Dist. Arm: parallel to lateral aspect of 5th metatarsal
Ankle goniometer alignment for extension
- Fulcrum: Lateral aspect of lateral malleolus
- Prox. Arm: head of fibula, using lateral midline
- Dist. Arm:parallel to lateral aspect of 5th metatarsal
Ankle goniometer alignment for eversion (tarsal)

Plantarflexion positioning
- Sitting with knee flexion to 90º
- Making sure ankle is in 0º inversion/eversion
- Can also be done in supine or prone for a non-weight bearing position
Dorsiflexion positioning
- Sitting with knee flexion to 90º
- Making sure ankle is in 0º inversion/eversion
- Can also be done in supine or prone for a non-weight bearing position
Talar Inversion positioning
- Sitting with knee flexion to 90º
- Lower leg on edge of a supporting surface
- Hip should be in 0º abduction, adduction, and rotation
Talar eversion positioning
- Sitting with knee flexion to 90º
- Lower leg on edge of a supporting surface
- Hip should be in 0º abduction, adduction, and rotation
Ely Test (Rectus Femoris length evaluation) Testing Plane
Sagittal
Ely Test (Rectus Femoris length evaluation) Testing Position
Prone with both feet off the end of the table.
Ely Test (Rectus Femoris length evaluation) Limb Position
Knees and hips begin at 0 degrees.
Ely Test (Rectus Femoris length evaluation) Stabilization
Stabilize the hip; do not allow the hip to flex.
Ely Test (Rectus Femoris length evaluation) Testing Motion
- Flex the knee by lifting the lower leg off the table;
- the end of ROM is when resistance is felt from the anterior thigh and further knee flexión causes the hip to flex.
Ely Test (Rectus Femoris length evaluation) Goniometer Alignment
- Fulcrum: lateral epicondyle of the femur
- Proximal Arm: lateral midline of femur (greater trochanter for reference)
- Distal Arm: lateral midline of fibula (lateral malleolus as reference)
Ely Test (Rectus Femoris length evaluation) Interpretation
Normal: knee can be flexed at least 90 degrees

Firm
Distal Hamstring Length Test (passive knee extension) Testing Plane
Sagittal
Distal Hamstring Length Test (passive knee extension) Testing Position
Supine with the hip on the side being tested in 90 degrees of flexion and 0 degrees of ABD/ADD/Rotation.
Distal Hamstring Length Test (passive knee extension) Stabilization
Femur
Distal Hamstring Length Test (passive knee extension) Testing Motion
- Extend the knee to the end of ROM.
- The end of testing motion is when resistance is felt from tension in the posterior thigh and further knee extension causes the hip to extend.
Distal Hamstring Length Test (passive knee extension) Goniometer Alignment
- Fulcrum: lateral epicondyle of the femur
- Proximal Arm: lateral midline of the femur (greater trochanter as reference)
- Distal Arm: lateral midline of the fibula (lateral malleolus as reference)

Gastrocnemius Length Test (supine non-weight bearing) Testing Plane
Sagittal
Gastrocnemius Length Test (supine non-weight bearing) Testing Position
Supine
Gastrocnemius Length Test (supine non-weight bearing) Limb Position
knee extended and foot in 0º inversion/eversion
Gastrocnemius Length Test (supine non-weight bearing) Stabilization
Weight of hand on knee to hold extension
Gastrocnemius Length Test (supine non-weight bearing) Testing Motion
Dorsiflex the ankle to the end of ROM.
Gastrocnemius Length Test (supine non-weight bearing) Goniometry Alignment
- Fulcrum: lateral aspect of lateral malleolus
- Proximal Arm: lateral midline of fibula, using head of fibula
- Distal Arm: parallel to lateral aspect of 5th metatarsal
Gastrocnemius Length Test (supine non-weight bearing) Interpretation
- Normal ROM values during knee extension in non-weight bearing position ranges from 10-20 degrees
- Measurements in weight bearing are greater than non weight bearing
