Background:~Patients with chronic low back pain (CLBP) frequently present with kinesiophobia. Recent high quality studies reported a moderate to strong evidence of associations between a greater degree of kinesiophobia and greater levels of pain, greater levels of disability and poorer quality of life. However, there are paucity of studies in associating kinesiophobia to muscle endurance and position sense in patients with CLBP.~Objective:~The primary aim of the study is to compare the impact of kinesiophobia on lumbar extensor endurance, position sense in patient with CLBP and asymptomatic individuals. Secondarily, to examine the association between kinesiophobia and lumbar extensor endurance, position sense, pain intensity and functional ability in patients with CLBP. Thirdly to assess the degree of association with various factors on CLBP, lumbar endurance and position sense.~Material and Methods:~This case-control study will have 200 patients with CLBP and 400 controls. Kinesiophobia will be assessed with Tampa Scale for Kinesiophobia. Lumbar endurance will be assessed with Soren's lumbar extensor test and lumbar position sense with neutral and target lumbar re-positioning tests. Secondarily, the pain intensity will be assessed with visual analog scale, functional ability with patient-specific Functional Scale in patients with CLBP. Kinesiophobia, lumbar endurance, and joint position sense will be compared between patients and controls. Kinesiophobia scores will be correlated with lumbar extensor endurance and proprioception joint position errors, pain intensity, and functional ability. Simple and multiple binary logistic regression will be used to determine crude and adjusted Odd's Ratio for kinesiophobia, lumbar position sense and kinesiophobia, lumbar endurance.
Though large body of evidence reported association between pain and kinesiophobia, there are paucity of studies in associating kinesiophobia to muscle endurance and position sense in patients with Chronic lower back pain [CLBP]. To the best of Investigator's knowledge, till date there is no studies assessing the relationship between kinesiophobia and endurance and position sense in subjects with CLBP. Therefore, the current study aims to compare the impact of kinesiophobia on lumbar extensor endurance, position sense in patient with CLBP and asymptomatic individuals.
