Goniometry of Ankle joint

Ankle goniometry

Type of joint: Hinge joint with one degree of freedom. The axis of motion is obliquely oriented in the transverse plane and passes along a line that connects two points just distal to tips of the malleoli. The movements of plantarflexion and dorsiflexion occur at this joint.

Ankle Dorsiflexion

Planes/axis of movement: Motion occurs in the sagittal plane around a coronal axis.

Range of motion:

โ€ข 0 degrees to 20 degrees

Goniometric alignment:

โ€ข Axis: Center over the lateral aspect of the lateral malleolus

โ€ข Stationary arm: Align with the lateral midline of the fibula, siting the fibular head

โ€ข Moving arm: Align with the lateral midline of calcaneus

Stabilization: The tibia and fibula must be stabilized by the clinician (or on a supporting surface if the subject is in supine or prone) to prevent hip or knee motion

Substitutions: The subject may try to flex the knee or hip to gain more range of motion or avoid pain during testing.

Ankle Plantarflexion

Planes/axis of movement: Motion occurs in the sagittal plane around a coronal axis.

Range of motion:

โ€ข 0 degrees to 45 degrees

Stabilization: The tibia and fibula must be stabilized by the clinician (or on a supporting surface if the subject is in supine or prone) to prevent knee or hip motion.

Substitutions: The subject may try to extend the knee or hip to gain more range of motion during testing.
