The slump test, a screening tool for neuropathic pain
Urban, Lawrence Michael
This study investigated the utility of using a neurodynamic test, the Slump test by itself and with qualifiers to identify neuropathic pain (NeP). The study utilized a control group and a low back pain group. The low back pain group was pre-diagnosed as NeP or non neuropathic pain (NNP) by an experienced clinician using an accepted diagnostic examination. A slump test was performed recording knee ROM, pain location and verbal pain descriptors followed by Quantitative Sensory Testing (QST). Various versions of the slump test were compared to the pre test diagnosis. Sensitivity, specificity and likelihood ratios were calculated. The conventional slump test was shown to be a sensitive and moderately specific screening test for NeP. Including whether pain extended below the knee dramatically increased specificity. QST revealed localized cold sensation hyposensitivity, widespread cold pain hyposensitivity and suggestions of increased thresholds of pressure pain levels.
