Mulders click and Sullivan’s Sign are two ways that help confirm Morton’s Neuralgia. They are both very useful because anyone can perform them very easily right at home. Mulder’s performed by squeezing the foot with one hand from side to side and trying to press on the site of the presumed neuroma; this should elicit a “clicking” sound.
How to Perform Mulder’s Click Test
- Squeeze the toes from side to side
- Press from both the top and bottom with the other hand to try to move the neuroma.
- Am for the interspace between the metatarsal heads.
- It doesn’t always click, but if it does- then the neuroma is that much more likely
Sullivan’s Sign shows a splaying of the 3rd and the 4th toes both on X-ray and when just looking at the foot normally. The thinking behind this is that if there is a big ball of tissue in between the toes, that they will look a little bit more spread out; which in some case is true. Both Sullivan’s sign and Mulders click are very easily performed at home; while both are not guaranteed tests, if positive they very highly indicate that a Morton’s Neuralgia may be present.
Other Tests to check for Morton Neuralgia
- Sullivan’s Sign.
- Xray to check for splaying.
Morton’s Neuralgia does not always show these tests!
Just because Sullivan’s sign or Mulders sign were not present does not mean that you don’t have a Morton’s Neuroma or neuralgia pain. The best way to diagnose this disorder is still clinical results!
- Do you have numbness, burning or tingling?
- Do you ever hear a clicking sound?
- Do you ever feel like there is a pebble in your foot?
- Does it ever feel like your socks are bunched up?
- Does massaging your foot ever make it feel better?
