At the end of this lab class:
You will be able to conduct basic assessment of the ankle and foot.
Basic Assessment of the Lower Leg, Ankle and Foot
Welcome to Lab Class 10!
In this labclass you will learn how AROM and PROM is performed for all possible movements of the ankle and foot.
It is important to realize that the ankle consists of two different joints:
- The talocrural joint is a hinge joint and the place where plantar flexion and dorsiflexion occur.
- The subtalar joint is considered a hinge joint as well, but the axis around which the joint is moving runs oblique. The possible movements at this joint are: inversion (a combination of plantar flexion, adduction and supination) and eversion (a combination of dorsiflexion, abduction and pronation)
In this video you will learn how AROM is performed for all possible movments of the ankle and foot:
After AROM, you want to passively assess the range of motion of the ankle and foot.
It is crucial that you check for compensations during the movements and that you fixate properly.
In this video you will learn how PROM is performed for all possible movements of the ankle and foot:
The capsular pattern for the talocrural joint is plantarflexion before dorsiflexion.
For more detailled information about the capuslar patterns of subtalar joint as well as the MTP and IP joints click here
The normal values for ankle range of motion are:
After you have assessed active and passive range of motion you would continue with resisted isometric muscle testing:
1) Practice the basic assessments of the ankle. Pay attention to move in one plane only. Can you think of a functional way to assess ankle dorsiflexion?
2) Examine a fellow student walking barefoot. Which movements occur at the ankle throughout stance phase? Write them down and share your answers in the Google Drive or Forum.
Preparation for next week:
1) Grab a skeleton and locate important bony landmarks. Try to palpate the different bones of the foot on a fellow student.
