Trial summary

Non-specific low back pain is defined as a pain with no specific vertebral-related cause, such as infectious disease, tumor, osteoporosis, fracture, structural abnormality, inflammatory disease, radicular compressive syndrome or cauda equine syndrome. Non-specific low back pain is a common disease in many countries. Read more about this study

About this study

Official title: Immediate Effects of a Spinal Lumbar Manipulation on the Threshold Pressure Pain and the Postural Control in Subjects With Non-specific Low Back Pain

Non-specific low back pain is defined as a pain with no specific vertebral-related cause, such as infectious disease, tumor, osteoporosis, fracture, structural abnormality, inflammatory disease, radicular compressive syndrome or cauda equine syndrome. Non-specific low back pain is a common disease in many countries. This musculoskeletal disorder is costly to public health systems. Therefore, the use of manual therapies is important in the treatment of this disease and studies show the effectiveness of this type of therapy.

Spinal manipulation is applied in manual therapies such as Osteopathy, Chiropractic and Physical Therapy and is widely used for acute and chronic non-specific low-back pain. There is moderate evidence that spinal manipulation is superior to sham spinal manipulation for improving short-term pain and function in chronic and acute non-specific low back pain. However the therapeutic mechanisms involved in this procedure are not well understood. Furthermore, while the high velocity and low amplitude spinal therapy has been shown to be effective in reducing pain and improving functional capacity in subjects with non-specific low back pain, the effect on postural variables have not been investigated. Therefore, the aim of this study is to evaluate the acute effect of lumbar manipulation on pain and postural variables.

Twenty-four individuals with non-specific low back pain will be randomly allocated to two groups. The intervention group will receive high velocity and low amplitude spinal therapy, while the control group will receive sham manipulation. Immediately before and after the respective manipulation protocol, both groups will be evaluated regarding pain level, using a visual-analogue scale and algometer, and postural variables, using center of pressure displacement measured with the aid of a force plate. While the patient and therapist manipulator will be aware of the protocol applied in each case, the evaluator will be blind. A statistical treatment will be used to compare the results.

Read the detailed description

Mean and standard deviation are calculated for each variable of postural control, as well as the values obtained in the measurement of pain using the numeric pain rating scale and algometry data.

t-test or Mann-Whitney test will be used to compare data before and after the manipulation protocol.

Multiple One-Way ANOVAs will be used to compare the manipulation protocol, for each dependent variable: effects of pain and center of pressure displacement.. Statistical analysis will be conducted with a confidence interval of 95%, α value of 5%, p value of ≤ 0.05.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HVLA ManipulationOther

    Intervention Group who receives a high velocity and low amplitude (HVLA) lumbar manipulation. A manual procedure also known as high velocity and low amplitude lumbar spinal manipulation are delivered for the subjects in the side lying position. The lumbar segment more restrict (mobility restriction) will be the target region for the manipulative procedure.

What is being measured

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

  1. pressure pain threshold assessment (algometer)

    An algometer will used to assess the pressure pain threshold at baseline and following the intervention

    Measured: Within one day

Secondary outcomes (3)
  1. Clinical Prediction Rule

    Variables which encompass the clinical prediction rule: symptoms lower than 16 days, Fear Avoidance-Beliefs Questionnaire lower than 19 in the work subscale, segmental lumbar hypermobility test in prone decubitus, internal hip rotation higher than 35 degrees and symptoms that don't pass the knee.

    Measured: Within one day

  2. Center of pressure displacement

    A force platform will be used to measure the displacement of the center of pressure (COP) in the anterior-posterior direction at baseline and following the intervention

    Measured: Within one day

  3. Subjective pain assessment

    Visual-analogue scale will be used to obtain a subjective assessment of pain at baseline and following the intervention

    Measured: Within one day

Questions about this trial

What is this clinical trial studying?

A study testing HVLA Manipulation in people with Low Back Pain, run by Federal University of Rio Grande do Sul at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pressure pain threshold assessment (algometer) (time frame: Within one day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02312778, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2015.
