Eversion Stress Test |
Examination type |
Ligamentous Stability |
Patient & Body Segment Positioning |
The patient is short sitting at the edge of the
table with the ankle in a neutral planter flexion to eversion
positioning. |
Examiner Position |
The examiner, sitting in front of the athlete, will stabilize
the lower leg with one hand by grasping the tibia and grasp the
calcaneus while holding the foot in neutral with the other hand. |
Tissues
Being Tested |
deltoid ligament |
Performing the Test |
Knee is bent 900 and gastrocnemius is relaxed. The
heel is held from below by one hand while the other hand holds
the lower leg. The hand on the heel is placed somewhat inferior
medial and is used to push the calcaneus and talus into eversion
while the other hand grips the lower leg laterally and pushes
medially. |
Positive Test |
The talus tilts excessively as compared with the uninjured side
or pain is produced. |
Interpretation |
If the injured ankle is more loose when
passively everted then a Ligamentous sprain to the medial side
is prevalent |
Common errors in
performing exam |
Bad hand placement, absence of proper medical
history, not performing the test in neural, plantarflexion and
dorsiflexion to stress each deltoid ligament.
|
Factors possibly
resulting in misinterpretation |
If the examiner dose not perform the test with
proper hand placement or passive ankle movement then
misinterpretation can become a factor. |
