To investigate the feasibility of a knee proprioception evaluation using a dynamometer as a tool for evaluating proprioception of the lower extremities in patients with incomplete spinal cord injury (SCI), and to explore its usefulness in predicting the ambulatory outcome. A total of 14 SCI patients (10 tetraplegic, 4 paraplegic; all AIS D) were included in this study. The passive repositioning error (PRE) and active repositioning error (ARE) were measured with a dynamometer, along with tibial somatosensory evoked potential (SSEP) and abductor hallucis motor-evoked potential (MEP). Ambulatory capacity was assessed with the Walking Index for Spinal Cord Injury II (WISCI-II), both at the time of the proprioception test (WISCI_i) and at least 6 months after the test (WISCI_6mo). The PRE showed a negative correlation with WISCI_i (r=-0.440, p=0.034) and WISCI_6mo (r=-0.568, p=0.010). Linear multiple regression showed the type of injury, lower extremities motor score, MEP, and PRE accounted for 75.4% of the WISCI_6mo variance (p=0.080). Proprioception of the knee can be measured quantitatively with a dynamometer in patients with incomplete SCI, and PRE was related to the outcome of the ambulatory capacity. Along with the neurological and electrophysiological examinations, a proprioception test using a dynamometer may have supplementary value in predicting the ambulatory capacity in patients with incomplete SCI.

To investigate the predictive value of enhanced-magnetic resonance imaging (MRI) and fluoroscopic factors regarding the effects of transforaminal epidural steroid injections (TFESIs) in low back pain (LBP) patients with lumbosacral radiating pain. A total of 51 patients who had LBP with radiating pain were recruited between January 2011 and December 2012. The patient data were classified into the two groups ‘favorable group’ and ‘non-favorable group’ after 2 weeks of follow-up results. The favorable group was defined as those with a 50%, or more, reduction of pain severity according to the visual analogue scale (VAS) for back or leg pain. The clinical and radiological data were collected for univariate and multivariate analyses to determine the predictors of the effectiveness of TFESIs between the two groups. According to the back or the leg favorable-VAS group, the univariate analysis revealed that the corticosteroid approach for the enhanced nerve root, the proportion of the proximal flow, and the contrast dispersion of epidurography are respectively statistically significant relative to the other factors. Lastly, the multiple logistic regression analysis showed a significant association between the corticosteroid approach and the enhanced nerve root in the favorable VAS group. Among the variables, MRI showed that the corticosteroid approach for the enhanced target root is the most important prognostic factor in the predicting of the clinical parameters of the favorable TFESIs group.
