Use of kinematic algorithms to distinguish people with chronic non-specific low back pain from asymptomatic subjects: A validation study.

Abstract: Objective: To determine whether kinematic algorithms can distinguish subjects with chronic non-specific low back pain from asymptomatic subjects and subjects simulating low back pain, during trunk motion tasks. Design: Comparative cohort study. Subjects: A total of 90 subjects composed 3 groups; 45 chronic non-specific low back pain patients in the CLBP group; 45 asymptomatic controls people in the asymptomatic controls group. 20/45 subjects from the asymptomatic controls group composed the CLBP simulators gro… Show more

“…Estimation of the required sample size was calculated on the basis of the minimal detectable change 95% of the primary outcome measure (KA-R and KA-S) 20 with a desired power of 0.80 and an α level of .05; we have obtained an estimation of the sample size in each group from 16 patients. Similarity of baseline measures between groups (T0) was assessed using a Student t test.…”

“…This multidimensional aspect of pain requires that measurement of pain should include not only subjective ratings, but also psychological and neurophysiological events related to pain perception. Accordingly, research on cognitive pain has been conducted using several approaches and tools such as questionnaires (Pagé et al, 2015;Traeger et al, 2016), Quantitative Sensory Tests (QST) (Cruz-Almeida and Fillingim, 2014;Cámara et al, 2016), genetic factors (Diatchenko et al, 2005;Ablin and Buskila, 2015;Ultsch et al, 2016), patterns of physical activity (Hidalgo et al, 2012(Hidalgo et al, , 2014Paraschiv-Ionescu et al, 2012), EEG (Pinheiro et al, 2016), neuroimaging (Davis et al, 2012;Schmidt-Wilcke, 2015), and more recently functional near-infrared spectroscopy (fNIRS) (Lopez-Martinez et al, 2018.…”
