The Validity of Neurodynamic Tests in the Lower Limb Part 2 Straight Leg Raise and Slump Test

“The impact of neurodynamic testing on the perception of experimentally induced muscle pain” Coppetiers et al 2005

Again, similar to the LAI et al 2012 paper, this paper sought to look at the Validity of the Straight Leg Raise and Slump test. Similarly it could really only look at the SPECIFICITY of the tests. So they injected saline into the Tibialis Anterior muscle on 15 people and performed the SLR on them. They injected saline into the soleus muscle in 10 people and performed a neurodynamic slump. Again like the LAI 2012 study they took the SLR and Slump to just short of stretch sensation (Again was this enough to implicate the nerve ?)

For the slump test, they added each component in turn and performed it 3 times on each participant – 1st time prior to the injection and then 2 post injection tests. There was a tendenccy for pain to decrease with time – this was either due to dispersion of the saline with movement or due to stimulation of joint and ligament afferents which cause spinal and supraspinal effects on pain. They nicely justified the range to which they took patients into the neurodynamic test by stating that this equalled the range of movement at which point symptoms were elicited in a group of symptomatic patients with LBP +/- ipsilateral leg pain.

In this study they did not find a significant increase in pain score in either Slump or SLR which like the LAI study may add some weight to the SPECIFICITY of these two neurodynamic tests.
