Heel pain and neural tension?
I am confused by a patient I saw today who complains of sharp, I/T (L) heel pain ( posterior-medial on palpation)when sit for >½ hour, it eases immediately when she stands up and walks or if she stretches her calf muscles. She has had this pain the last 2 weeks, after being treated for left knee pain (bad OA and patella femoral pain, worsened after fall 2/12 ago) and LBP (LBP started 1 month ago, but has longstanding back pain and stress #'s (not seen xray yet and patient didn't know where) and reports having Osteoporosis. She states that when heel pain gets bad, her LBP starts.
I initially thought lumbar referred pain due to aggravating behavior, but when tested Lx AM's I only reproduced LBP. (Could not do OP's due to fear of stressing spine too much)
When i did SLR LBP was reproduced very early in range ( 15 deg) bilaterally and DECREASED with passive dorsiflexion (???)
No heel pain was reproduced.
I found stiffness in her subtalar joint, and when i distracted her Calcaneous on Talus her pain was abolished (from 5/10).
I am confused about her neural tension result, and why dorsiflexion also reduces her heel pain.
I would like to perform a neuro examination on her next visit and also do a gentle PAIVM examination of her lx spine to just clear any chance of referred pain.
What's her diagnosis?
I am currently thinking that her stiff subtalar joint is causing the plantar fascia pain, and by mobilising the joint we can reduce the compression from tight gastrocks/soleus and plantar fascia- but shouldn't the pain increase when she does active dorsiflexion?
Any comments to this??

You discovered neural mobilization?
Hi Keen,
Do not be confused there. The results are quite normal for those who use neurodynamics’ stuff.
You have done a neural mobilization (gentle stretching of nerves/neural tissues) and pain was normally reduced.
A LBP may produce side effects at distance and you’re not confused with a sciatica case which is quite similar and you know that a sciatica may produce foot problems!
Re: You discovered neural mobilization?
So are you saying it's likely to be a Lx referred problem even though no heel pain was brought on by stressing the lumbar spine, or are you suggesting it's the sciatic nerve which has adverse neural tension? and why the improvement with added dorsiflexion in SLR position?

Re: You discovered neural mobilization?
Hi Keen,
You said that a SLR was painful. A SLR test is a neural test which often/ever produces a tension over the sciatic nerve. But a nerve is a physical entity which has limited elastic properties.
But if you stretch lightly the sciatic nerve, you give a bit ROM to the nerve and reduce immediately pain. It is why you got quick improvement with dorsi-flexion.
Here is an visual explanation with a flash animation.

So, you may have no pain at heel when provoking lumbar spine but pain when doing a SLR where sciatic nerve is already near its limits.
