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.

Detailed Description

Chronic low back pain may be associated with pathoanatomical, neurophysiological, physical, psychological and social factors. Treatments that relieve the symptoms of these patients are of great importance to improve the quality of life of these individuals. Thus, this study aims to evaluate the effects of transcranial direct current stimulation combined with Pilates based exercise on chronic low back pain. This is a randomized clinical trial that will be composed of men and women between 18 and 65 years of age, with a history of low back pain for more than 12 weeks and a minimum pain intensity equal to 3 cm on the numerical pain scale. The volunteers will be randomized into two distinct groups: stimulation + exercise group (EG - will perform a Pilates based exercise protocol combined with transcranial direct current stimulation) and sham stimulation + exercise group (SG - will perform the same exercise program combined with sham stimulation). The interventions, regardless of the group, will be carried out three times a week for four weeks. Participants will be submitted to three assessments: the first (T0) will be performed before the treatment protocols; the second (T1) will be performed after the four weeks of intervention; and the third (T2) will be a follow-up one month after the end of the treatment protocol. Pain sensation, functional performance, central sensitization, quality of life, pressure pain threshold, global impression of change, adverse events and medication use will be evaluated. For the statistical analysis, a mixed model ANOVA will be performed for the inter and intragroup comparison, with Tukey's post hoc, considering a significance level of 5%.

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.

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: Stimulation + exercise group
30-minute exercise program (based on Pilates method) combined with active transcranial direct current stimulation.
Device: Transcranial direct current stimulation
Exercise protocol + application of active direct current stimulation for 30 minutes.
SHAM_COMPARATOR: Sham stimulation + exercise group
This arm will perform the same procedures of experimental group but the stimulator will be turned off after 30 seconds and the volunteers will not receive current for the rest of the session.
Device: Sham Transcranial direct current stimulation
Exercise protocol + application of simulation of direct current stimulation for 30 minutes. The stimulator will be turned off after 30 seconds and the volunteers will not receive current for the rest of the session.

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
Pain intensity
Time Frame: Change from baseline in pain intensity at four weeks after intervention and 1 month of follow-up
Pain intensity measured by numerical pain rating scale (11 points scale)
Change from baseline in pain intensity at four weeks after intervention and 1 month of follow-up
Functional performance associated to back pain
Time Frame: Change from baseline in functional performance at four weeks after intervention and 1 month of follow-up
Functional performance associated with low back pain measured by Roland Morris Disability Questionnaire (24 itens)
Change from baseline in functional performance at four weeks after intervention and 1 month of follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pressure pain threshold
Time Frame: Change from baseline in pressure pain threshold at four weeks after intervention and 1 month of follow-up
Pressure pain threshold measured by pressure algometer.
