Subtalar Jt

Question 1

Calcaneal Inversion

Answer 1

(0 – 10 or 15 degrees)
Another means of reporting the normal range of motion is to state that “most individuals have two to three times more inversion than eversion.”

Question 2

Calcaneal Inversion Positioning

Answer 2

• Prone at edge of table, neutral hip rotation, foot off end of table
• Normal End Feel: Firm (due to tissue tension on the lateral aspect)

Question 3

Goniometer-Calcaneal Inversion

Answer 3

USE Broad-arm (ruler) goniometer

• Fulcrum/ Axis: posterior aspect of the ankle at the midpoint between the malleoli (no boney reference other than the malleoli)

• Stationary Arm: posterior midline of the lower leg (no boney reference)
• Moving Arm: posterior midline of the calcaneous

Question 4

Calcaneal Eversion

Answer 4

(0 – 5 degrees)
Another means of reporting the normal range of motion is to state that “most individuals have two to three times more inversion than eversion.”

Question 5

Calcaneal Eversion Postioning

Answer 5

• Patient position, goniometer and goniometer alignment is the same as for subtalar joint, hindfoot, rearfoot, calcaneal inversion.
• Normal End Feel: Hard (due to contact between the calcaneus and the floor of the sinus tarsi) or Firm (due to tissue tension on the medial aspect)
