Gastrocnemius Tightness - Everything You Need To Know - Dr. Nabil Ebraheim

Educational video describing tightness of the Gastrocnemius muscle.
Dorsiflexion of the ankle is limited with tightness of the gastrocnemius muscle. The gastrocnemius muscle spans across the knee joint. The gastrocnemius muscles relaxes with flexion of the knee and this improves the ankle dorsiflexion.
Silfverskiold knee flexion test: this knee flexion test measures the range of ankle dorsiflexion with the knee flexed and the ankle straight. More ankle dorsiflexion with the knee flexed indicates gastrocnemius tightness.
Achilles tightness: with Achilles tendon tightness or contracture, ankle dorsiflexion is the same with knee extension and flexion. The degree of dorsiflexion does not change regardless of the knee position involving tightness of the Achilles tendon.
