Prognostic Factor Research of Sensory Profiles in Development of Central Sensitization

Vrije Universiteit Brussel102 enrolled

Overview

A longitudinal observational cohort study to investigate the value of prognostic factors, here sensory profiles , and others, in the development of central sensitization in the low back pain population. A type 2 prognostic factor research following the PROGRESS framework. Sensory profiles are identified a prognostic factors which can predict the development of central sensitization in the low back pain population.

After performing an univariable linear regression analyses the regression model predicts the dependent variable, central sensitization, significantly, and the models are significant prediction factors of the development of central sensitization. In unadjusted analyses, all four sensory profiles were significantly associated with the development of central sensitization (P\<0.001). After adjusting for pain, disability, age, and duration of low back pain, baseline sensory profiles remained significant predictors of central sensitization. On the other hand, all other predictor variables did not contribute to the prediction of central sensitization.

Outcomes

Primary Outcomes

Central Sensitization Inventory score

The validated questionnaire Central Sensitization Inventory which scores on a 5 point scale ranging from 0-100. A higher score indicated a higher degree of central sensitization.

Time frame: 12 weeks

Adolescent/Adult Sensory Profile score

Adolescent/Adult Sensory Profile measures 4 sensory profiles (sensation avoiding, sensation sensitive, sensation seeking, low registration) on ad 5 point scale, and is validated in the low back pain population. Scores range from 15-60 points per variable. A higher score means a higher degree of sensitivity for the specific sensory profile.

Time frame: 0 weeks

Secondary Outcomes

Numeric Pain Rating Scale score

Numeric Pain Rating Scale measures experienced level of pain, which consist of one question ranging van 0 (no pain)-10 (most extreme pain imaginable).

Time frame: Baseline (0 weeks)

Pain Disability Index score

The Pain Disability Index evaluates the effect on seven life-related domains. Each domain is measured by 1 question, with a total of 7 questions, on an 11 point scale, from 0 (no disability) to 10 (completely disabled). Previously established reliability and internal consistency are acceptable in patients with chronic pain.

Time frame: Baseline (0 weeks)

age

The included age (years) ranged from 18-60 score. A higher age indicates a worse prognoses of low back pain.

Time frame: Baseline (0 weeks)

duration of low back pain

Duration of low back pain was assessed in weeks. The included duration of low back pain ranged from 0-6 weeks. A longer duration is not better or worse.
