August 12, 2026 updated by: Pablo Hernandez-Lucas, University of Vigo

Effect of an Intervention Based on Back School in an Aquatic Environment on Non-specific Low Back Pain: Randomized Controlled Trial

A controlled and randomized clinical trial will be conducted, in which scores on dependent variable measures will be compared before and after the intervention, both in the experimental group (EG) (individuals who will attend the in an aquatic program based on the back school) and in the control group (CG) (individuals who will not attend the in an aquatic program based on the back school). The experimental procedure will follow the recommendations of the CONSORT and TidIER guidelines. The study protocol will be approved by the Research Ethics Committee of the University of Vigo. This study will be conducted under the Declaration of Helsinki (2013 version). Participants will sign a written informed consent after being informed of the benefits and risks of the research. Participants in the EG will participate in an aquatic program based on the back school. This program will follow the recommendations of the biopsychosocial model of chronic pain and will be conducted in an aquatic environment. The intervention will be carried out by physiotherapists in a sports centre. The duration of the intervention will be six weeks, with a frequency of two sessions per week, totalling 12 sessions of 45 minutes each. Of all the sessions, 10 will have a practical focus and the other two will have a theoretical focus.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 18-65 years of age.
  • With non-specific low back pain for at least three months, with pain intensity (30-70 on a VAS).

Exclusion Criteria:

  • History of cancer, spine infection, rheumatologic diseases, history of spine fracture, history of trauma, red flag signs including unwanted weight loss (exceeding 10 percent of the total body weight) in the past six months and fever, history of psychological disease and history of spine surgery, radiculopathy, anatomical and congenital disturbance.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Aquatic program based on the back school
Participants will undertake a back school-based program. This program will follow the recommendations of the biopsychosocial model of chronic pain and will be conducted in an aquatic environment. The intervention will be carried out by physiotherapists in a sports center. The duration of the intervention will be six weeks, with a frequency of two sessions per week, totaling 12 sessions of 45 minutes each. Of all the sessions, 10 will have a practical focus (centered on trunk exercises) and the other two will have a theoretical focus (providing education on pain and risk factors for low back pain).
Behavioral: Aquatic program based on the back school
Participants will undertake a back school-based program. This program will follow the recommendations of the biopsychosocial model of chronic pain and will be conducted in an aquatic environment. The intervention will be carried out by physiotherapists in a sports center. The duration of the intervention will be six weeks, with a frequency of two sessions per week, totaling 12 sessions of 45 minutes each. Of all the sessions, 10 will have a practical focus (centered on trunk exercises) and the other two will have a theoretical focus (providing education on pain and risk factors for low back pain).
No Intervention: Control
They will continue with their usual lifestyle.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Tampa Scale Of Kinesiophobia.
Time Frame: Through study completion, an average of 2 months.
This scale measures kinesiophobia. The total scale score ranges from 11 to 44, where 11 means no kinesiophobia and 44 means severe kinesiophobia.
Through study completion, an average of 2 months.
Visual Analogue Scale.
Time Frame: Through study completion, an average of 2 months.
The visual analogue scale is a widely used tool to measure pain. The patient is asked to indicate the intensity of the pain they perceive (most commonly) along a horizontal line from 0 millimetres (minimum value) to 100 millimetres (maximum value), and this score is then measured from the left edge, the higher the value in millimetres the more pain.
Through study completion, an average of 2 months.
Roland Morris Disability Questionnaire.
Time Frame: Through study completion, an average of 2 months.
The Roland Morris Disability Questionnaire Scoring is a 24-item patient-reported outcome measure that inquires about pain-related disability resulting from LBP. Items are scored 0 if left blank or 1 if endorsed, for a total Roland Morris Disability Questionnaire score ranging from 0 to 24; higher scores represent higher levels of pain-related disability.
Through study completion, an average of 2 months.
Short-Form Health Survey-36.
Time Frame: Through study completion, an average of 2 months.
Short-Form Health Survey was used to measure quality of life.The Short-Form Health Survey-36 explores people's physical and mental health. It consists of 36 items that assessed eight dimensions of health status: social function, physical function, emotional role, physical role, mental health, vitality, physical pain, and general health. Scores ranged from 0 (worst health status) to 100 (best health status).
Through study completion, an average of 2 months.
