Goniometry (Knee and Ankle) Flashcards
Knee goniometer alignment
- Fulcrum: lateral femoral epicondyle
- Prox. Arm: greater trochanter
- Dist. Arm: lateral malleolus
Knee Flexion ROM
0-130/140º
Knee Extension ROM
0º
*(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
- 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 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)
- Fulcrum: anterior aspect of ankle between malleoli
- Prox. Arm: ant. Midline of lower leg using tibial tuberosity
- Dist. Arm: ant. Midline of 2nd metatarsal
Ankle goniometer alignment for inversion (tarsal)
- Fulcrum: anterior aspect of ankle between malleoli
- Prox. Arm: ant. Midline of lower leg using tibial tuberosity
- Dist. Arm: ant. Midline of 2nd metatarsal
