About this study

Official title: Effectiveness of Hamstring Muscle Dry Needling in Patients With Chronic Mechanical Low Back Pain of Non-specific Origin

This study evaluates the treatment of hamstrings in the management of patients with mechanical low back pain of non-specific origin. Half of the participants will received the application of a dry needle technique in the most hyperalgesic areas of the muscle, while the other half will received the same technique in areas not hyperalgesic.

Read the detailed description

Shortening of the hamstrings could be related to low back pain.Therefore, the treatment of these muscles may improve pain.

The dry needling technique seems to improve the extensibility of the muscles. This technique seems to be more effective when is applied in the most hyperalgesic areas related to the participant's pain.

In order to demonstrate this hypothesis, the investigators will check if the dry needling technique produces the same effects when is applied in other areas of those same muscles

What participants receive

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

  • Dry needling in hamstring muscle trigger pointsOther

    Also called intramuscular stimulation of muscle

    Participants with nonspecific mechanical low back pain will be assessed for the hamstring muscle. Subsequently, the most sensitive areas associated with the shortening of the muscle will be located and the technique will be applied to this area.

  • Dry needling in hamstring muscle not trigger pointsOther

    Participants with nonspecific mechanical low back pain will be assessed for the hamstring muscle. Subsequently, the most sensitive areas associated with the shortening of the muscle will be located and the technique will be applied out of this area.

What is being measured

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

  1. Low back pain

    The investigators use a Visual Analog Scale (VAS) to determine the intensity of the patient with blowback pain.The VAS is a 100-mm line, oriented horizontally, with one end representing "no pain" and the other end representing "worst pain." Subjects will be asked to rate their current pain with a mark on the scale.

    Measured: Change from Baseline Pressure Pain Threshold at 3 months

Secondary outcomes (3)
  1. Disability with Oswestry Disability Index

    The Oswestry Disability Index (ODI) is a questionnaire used by clinicians and researchers to quantify disability for low back pain.The self-completed questionnaire contains ten topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel.Each topic category is followed by 6 statements describing different potential scenarios in the patient's life relating to the topic. The patient then checks the statement which most closely resembles their situation. Each question is scored on a scale of 0-5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). Zero is equated with no disability and 100 is the maximum disability possible

    Measured: Change from Baseline disability at 3 months

  2. The extensibility of the hamstring muscle

    The extensibility of the hamstring muscle will be measured by the popliteal or active knee extension (AKE) test, with the patient supine on the stretcher, with the contralateral limb in extension, will placed with the hip at 90 degrees of flexion.

    While maintaining this position, the clinician tries to extend the knee. Limitation of knee extension is measured with a goniometer in degrees.

    Measured: Change from Baseline disability at 3 months

  3. Pressure Pain Threshold

    The PPT serves to determine the sensitivity of hiperalgesic focus. The investigators will done it with one algometer. A lower threshold is a worse result. A higher threshold is a better result.

    Measured: Change from Baseline Pressure Pain Threshold at 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Dry needling in hamstring muscle trigger points and Dry needling in hamstring muscle not trigger points in people with Low Back Pain, run by University of Alcala at 2 sites in Spain.

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 4 inclusion and 7 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 25 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Spain. 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. Some participants in this study may receive a placebo. 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?

Low back pain (time frame: Change from Baseline Pressure Pain Threshold at 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Oct 2023.
