← Human Body & HealthA patient experiences a ruptured Achilles tendon during a basketball game. Which compensatory biomechanical adaptation is most likely to occur acutely to maintain propulsion?
A)Increased plantarflexion force in affected leg
B)Decreased hip extension on the contralateral side
C)Reduced dorsiflexion range during stance phase
D)Greater reliance on hip flexors for push-off✓
💡 Explanation
When the Achilles tendon ruptures, plantarflexion is severely impaired; therefore, propulsion relies more on hip flexors to compensate. The body uses alternative strategies because the normal ankle plantarflexion mechanism is disrupted, rather than enhancing already compromised plantarflexion or reducing dorsiflexion, or affecting the contralateral leg.
