Sciatic Nerve Causing Plantar Fascitis? by Motion Stability

In the Journal of Orthopaedic Research – September 2006, Coppieters MW, Alshami AM, Babri AS, et al measured the strain and excursion of the sciatic, tibial and plantar nerves with a modified straight leg raise (SLR) test. By bending the ankle into dorsiflexion first before raising the leg, nerve movement at the ankle, particularly the tibial nerve was greatly increased. Clinically, the diagnosis of ‘plantar fascitis’ can be caused by multiple sources, one being sensitization of the tibial nerve which is a branch of the sciatic nerve. Thanks to Dr. Coppieters, as well as other neurodynamic specialists like Michael Shacklock MAppSc, DipPhysio, we now know that movement of nerves occurs greatest where joints move first, a concept called ‘neurodynamic sequencing’. By sensitizing the tibial nerve through the SLR test, or even a slump test (picture shown) we can differentially diagnose plantar fascitis as a peripheral nerve disorder.

I just came back from Seattle, WA for the American Academy of Orthopaedic Manual Physical Therapist (AAOMPT). The confrence was focused on pain, primarily on the new pain sciences that reserachers are beginning to unravel the multiple factors involved in chronic pain. Thanks to all the presenters for sharing your knowledge to help our clinical outcomes!

In patient care with complaints of recurring low back pain and sciatica. Patients need to consider that even though pain subsides down the leg through rest or interventions. That the sciatic nerve can become adhered through intraneural edema. And similar to a stiff elbow after removing a cast off it due to a fracture, the elbow may not be as painful but will be very stiff. Likewise, a reduction in symptoms down the leg, does not necessarily mean that the sciatic nerve is mobile. Thorough testing for nerve mobility, that is asymptomatic but could be asymmetrical to the unaffected side, at least from my clinical opinion, could be a factor to recurring sciatica and low back pain.
