Plantar Flexion

Plantar flexion: A sagittal plane joint action of the ankle that results in the foot pointing away from the body or downward. It is a decrease in the angle between the calcaneus and the posterior aspect of the tibia.

  • Opposing Joint Action: Dorsiflexion
  • Plane of Motion: Sagittal
  • Direction Bias: Down
  • Note: Joint actions may be referred to as "osteokinematic motions" or "osteokinematic joint actions" to differentiate them from "arthrokinematic motions " (e.g., spin, glide, roll, compression, and distraction).
