About this study

A two-armed randomized controlled clinical trial with blind assessments and a follow-up period of 4 weeks is developed. The aim of this study is to investigate the effects of the combination of heat and TENS (HeatTENS device) on pain in people with chronic low back pain. A sample of 70 patients will be recruited. Following baseline measurements, subjects will be randomly allocated to the experimental or the control group. The experimental group will be asked to use the device on a daily basis, 30 minutes per day. The control group will have no device. After 4 weeks of FU, measurements will be repeated.

Read the detailed description

Drop out:

If subjects drop out, due to any kind of reason, a new participant will be included in order to obtain the predetermined number of participants. Data collected from the participant that dropped out will be deleted and not taken into account in the further analysis.

Analysis of the samples:

Sample size is based on data from (Dailey et al. 2013). Researchers found a significant difference in the reduction of movement-evoked pain (pain during the 6 minutes' walk test (6MWT)) ((4.0 ± 2.5) on a 0-10 VAS) when compared to no TENS (5.0 ± 2.6) (p<0.05) in patients with primary fibromyalgia.

In this study the response within each subject group was normally distributed. If the true difference in the experimental and control means is 1.0, effect size is calculated to be 0,2 (by means of G*Power version 3.1.9.3). 29 experimental subjects and 29 control subjects need to be included to be able to reject the null hypothesis that the population means of the experimental and control groups are equal with probability (power) 0.8. The Type I error probability associated with this test of this null hypothesis is 0.05. To take into account a 15% loss of data sample size is inflated up to 33 per group (n/0.85). Sample size is augmented by 10% per potential confounding factor (i.e. age and sex). The total sample size to be recruited will be 70 subjects.

Statistical analysis:

The person to conduct the statistical analyses will be Lynn Leemans (Human Physiology and Anatomy (KIMA), Vrije Universiteit Brussel).

An intention-to-treat analysis will be performed so that the integrity of the randomization is ensured. Normality will be checked via the Shapiro-Wilk test.

To ensure good balance of participant characteristics in each group at baseline, stratification is used. Changes in differences between both treatment groups after the intervention period (at 4w) will be analyzed using repeated measures ANOVA for the following variables: sensitivity to movement-evoked pain, quality of life, pressure pain thresholds, temporal summation and conditioned pain modulation.

If the modulus of the partial correlation of potential confounding factors age and sex with the primary outcome values equals minimum 0.3, these covariates of prognostic values will be added as covariates in the ANOVA model.

As a secondary analysis, a linear regression analysis will be used with the following dependent factors: BMI, and as independent factors: sensitivity to movement-evoked pain, pressure pain thresholds, temporal summation, conditioned pain modulation, fear avoidance beliefs and quality of life.

Significance value for all tests will be set at p < 0.05. All analyses will be performed using SPSS 20 for Mac.

Quality control and quality assurance:

All electronic data will be stored on the shared drive of a university computer, which is encrypted; and on a password protected laptop belonging to the principal researcher (Lynn Leemans). Transfer of data will only be done if essential.

All anonymised data will be stored for up to four years to allow for access before publication, and may be required at a later date for further analysis and auditing. All personal data, including health questionnaires and signed consent forms, will be destroyed within 12 months of the study finishing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Movement Evoked Pain

    Pain that is experienced in response to a physical task. Participants will perform 5 physical tasks (= 1) grasping toes with fingertips in a sitting position; 2) forward bending from standing; 3) picking up paper from standing; 4) long-sitting from supine and 5) lifting a 5kg box from floor to table). Participants will provide a pain rating on a 11 points Numeric Rating Scale (NRS) with the endpoints no pain" (0) and "excruciating pain" (10)

    Measured: Change from Baseline Movement Evoked Pain after treatment and at 4 weeks

Secondary outcomes (8)
  1. 5 minute walk test (5MWT)

    Subjects need to walk as far as possible in 5 minutes

    Measured: Change from Baseline 5MWT after treatment and at 4 weeks

  2. Pressure Pain Threshold (PPT)

    This measures deep tissue hyperalgesia, defined as the point at witch the pressure sensation turned into pain.

    Measured: Change from Baseline Pressure Pain Threshold after treatment and at 4 weeks

  3. Temporal summation (TS)

    This is used to evaluate (endogenous) pain facilitation. Temporal summation is induced trough 10 pressure pulses with a hand held algemener (Somedic AB, Farsta, Sweden) at the Pressure Pain Threshold intensity. Patients will rate their pain level at the first, 5th and 10th pulse. Participants will provide a pain rating on a 11 points Numeric Rating Scale (NRS) with the endpoints no pain" (0) and "excruciating pain" (10)

    Measured: Change from Baseline Tempral Summation after treatment and at 4 weeks

  4. Conditioned pain modulation

    This is used to evaluate the ability of the brain to moderate pain. In Conditioned pain modulation, a painful stimulus produces a decrease in pain outside the area of the applied stimulus. The mechanism behind it can be described as "pain inhibits pain". To induce pain and therefore trigger CPM response, participants put their hand in cold water for 2 minutes. Patients need to rate their level of pain (applied stimulus) on a 11 points Numeric Rating Scale (NRS) with the endpoints no pain" (0) and "excruciating pain" (10)

    Measured: Change from Baseline Conditioned pain modulation after treatment and at 4 weeks

  5. Fear Avoidance Beliefs Questionnaire- work

    Catastrophic thoughts and believes in chronic pain patients

    Measured: Change from Baseline Fear Avoidance Beliefs Questionnaire after treatment and at 4 weeks

  6. Quality of life (SF-36)

    Quality of life, due to their low back pain, experienced by the patients will be evaluated

    Measured: Change from Baseline Quality of Life after treatment and at 4 weeks

  7. Central sensitization inventory

    To report signs of central sensitization and its overlapping symptoms

    Measured: Change from Baseline Central sensitization inventory after treatment and at 4 weeks

  8. Body composition and Body Mass Index (BMI)

    These two assessments are used to evaluate overweight and obesity in chronic low back patients. Body composition will be described in percentages of fat and muscle (%). Weight (in kilograms) and height (in meters) will be assessed as well and will be combined to report BMI in kg/m^2. The ViVa body composition monitor (OMRON) will be used for these measurements. Accepted classification for overweight and obesity by BMI: <18.5 = underweight; 18.5-24.5 = normal; 25.0-29.9 = overweight and >30.0= obesity.

    Measured: Change from Baseline Body composition and BMI at 4 weeks follow up
