Psychological Predictors of Pain and Disability in Patients With Chronic Low Back Pain After Manual Therapy

Enrolling by invitation · Not applicable

Conditions studied: Low Back Pain, Disability Physical, Manual Theapy

In brief

Low back pain has been reported to cause more disability than any other musculoskeletal health condition worldwide. About eight out of ten people will experience back pain at least once in their lifetime. The parameters that are usually evaluated in a low back pain condition are pain, functional disability and range of motion of the lumbar spine. There are studies that associate psychological conditions (self-efficacy, kinesiophobia, catastrophology, depression, anxiety) with pain and functional disability in patients with low back pain. However, the ability of psychological factors to predict progression after a program of physical therapy or therapeutic methods is not well studied. The main purpose of this study is to investigate the predictive potential of psychological factors in the improvement of pain and functional disability after a manual therapy physiotherapy program in patients with chronic low back pain. A secondary purpose is to investigate the predictive potential of psychological factors in the improvement of pain and functional disability following a program of Pain Neuroscience Education (PNE) in patients with chronic low back pain. In addition, as a secondary purpose, it will be to investigate the effect of combining manual therapy therapy with PNE compared to manual therapy alone in patients with chronic low back pain. This study will involve 60 people aged 18-65 with chronic low back pain, who will be randomly divided by lots into 2 groups of 30 people. The 1st group (30 people) will be treated with manual therapy based on Maitland's principles (interview, evaluation, mobilization), without any use of physiotherapy machines, but with the use of personalized exercises. The 2nd group (30 people) will do the same as group 1 and additional volunteers will participate in before, in a training program in Pain Neuroscience Education (PNE). The total number of sessions that each volunteer will receive will be 6, the duration of each session will be about 45 minutes, the frequency of the sessions will be 2 times a week and the total duration of the intervention will be 3 weeks. The associations between psychological states and clinical characteristics (pain, disability and range of motion) will be carried out with the Pearson or Spearman correlation coefficient depending on whether the data are parametric or not. Multiple regression models will also be created with predictive factors for psychological states and a predictive variable for each of the clinical parameters. The significance level will be set to p=0.05.
