What is a positive Silfverskiold test? The test used to determine Gastrocnemius contracture This article refers to permanent shortening of muscles, tendons, or ligaments. For short-term contraction of muscles, see Muscle contraction. A muscle contracture is a permanent shortening of a muscle or joint. It is usually in response to prolonged hypertonic spasticity in a concentrated muscle area, such as is seen in the tightest muscles of people with conditions like spastic cerebral pals…Contracture
What is the Silfverskiöld test?
The Silfverskiöld test differentiates gastrocnemius tightness from an achilles tendon contracture by evaluating ankle dorsiflexion with the knee extended and then flexed. It measures the dorsiflexion (DF) of the foot at the ankle joint (AJ) with knee extended & flexed to 90 degrees.
Why don't doctors just ignore the Silfverskiold test?
They don't just blindly ignore it. Second, the Silfverskiold test determines the degree to which muscle contraction restricts range of motion at the ankle. This restricted range of motion can cause various problems with the foot.
Is the Silfverskiöld test underappreciated in the diagnosis of gastrocnemius contracture?
This study demonstrates that if the Silfverskiöld test is not performed correctly, the diagnosis of an isolated gastrocnemius contracture could be underappreciated.
What does a positive test for dorsiflexion mean?
It measures the dorsiflexion (DF) of the foot at the ankle joint (AJ) with knee extended & flexed to 90 degrees. The test is considered positive when DF at the AJ is greater with knee flexed than extended. The test is performed with the patient seated or in supine.
What is a Silverskold test?
What is the Silfverskiold Test? Silfverskiold Test is used to evaluate the contracture of the ankle joint whether it's caused by gastrocnemius muscle contracture or by the Achilles tendon contracture. It measures the dorsiflexion of the foot at the ankle joint with knee extended and flexed to 90 degrees.
How do you test for gastrointestinal tightness?
The diagnosis of gastrocnemius tightness is primarily clinical using the Silfverskiold test, which shows an equinus deformity at the ankle with the knee extended but that disappears with the knee flexed.

Then ask your patient to bring one knee to his chest and to hold it afterwards.
How do you test for ankle dorsiflexion?
Lift your foot up and move it around. As you can see and feel, it can move in several different directions. If you point your toes like a ballerina, that is called ankle plantarflexion. If you pull your toes and foot towards your knee, that is ankle dorsiflexion.
How is contracture treated?
Nonsurgical options include:wearing open-back shoes, such as clogs.taking nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin IB) or aspirin (Bufferin)icing the bump for 20 to 40 minutes per day to reduce swelling.getting ultrasound treatments.getting a soft tissue massage.wearing orthotics.More items...
What is a bone contracture?
Deformity - contracture. A contracture develops when the normally stretchy (elastic) tissues are replaced by nonstretchy (inelastic) fiber-like tissue. This tissue makes it hard to stretch the area and prevents normal movement.
What causes fingers to draw up?
Dupuytren's (du-pwe-TRANZ) contracture is a hand deformity that usually develops over years. The condition affects a layer of tissue that lies under the skin of your palm. Knots of tissue form under the skin — eventually creating a thick cord that can pull one or more fingers into a bent position.
What is the normal range of dorsiflexion?
The normal range for ankle joint dorsiflexion was established as 0 degrees to 16.5 degrees nonweightbearing and 7.1 degrees to 34.7 degrees weightbearing.
What is dorsiflexion important for?
Dorsiflexion as you run puts your foot in an ideal position to absorb the shock of the landing and tenses your muscles to spring forward into the next stride. This allows a reduced ground contact time per stride, allowing you to run faster and more efficiently.
What does good dorsiflexion look like?
Share on Pinterest Dorsiflexion is the movement of the foot upwards, so that the foot is closer to the shin. For a movement to be considered dorsiflexion, the foot should be raised upward between 10 and 30 degrees.
Purpose
The Silfverskiöld test commonly used to identify isolated gastrocnemius contracture associated with several foot and ankle pathologies was first described by Nils Silfverskiöld . The Silfverskiöld test differentiates gastrocnemius tightness from an achilles tendon contracture by evaluating ankle dorsiflexion with the knee extended and then flexed.
Technique
It measures the dorsiflexion (DF) of the foot at the ankle joint (AJ) with knee extended & flexed to 90 degrees. The test is considered positive when DF at the AJ is greater with knee flexed than extended.
Evidence
Inter- and intrarater reliability testing of the clinical Silfverskiöld test : ICC values of 0.230 to 0.791. poor inter- and intrarater reliability.
Craig Payne Moderator
There are theoretically no normal values as general there is a subject specific normal values that probably vary substantially from person to person.
