Study participants 36 subjects diagnosed with non-specific chronic low back pain, which will be divided in two groups with 18 subjects in each: experimental group, which will be submitted to placebo + exercise shortwave diathermy and the control group to do active + exercise shortwave diathermy. There will be 12 one-hour sessions twice a week. The subjects will apply Shortwave Diathermy for 20 minutes, followed by Pilates mat.

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.

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.
Placebo Comparator: Pilates and Shortwave placebo
In this group the patients will receive 20 minutes of short wave placebo application. The equipment will keep the timer on and the intensity will remain at zero. The patient will be informed that the dose is subsensory and therefore there will be no perception of the passage of the short waves through the body.The application will be performed with two coplanar plates in parallel, arranged on the right and left side of the lumbar region, maintaining a distance of 5 to 10 cm between them, with the patient lying in the dorsal decubitus position
Device: Pilates and Shortwave placebo
Pilates exercises and application of the device without produce thermal effects
Active Comparator: Pilates and Shortwave active
In this group the patients will receive 20 minutes of application of the Shortwave Active continuous mode (thermal effect), with vigorous local thermal sensation.The application will be performed with two coplanar plates in parallel, arranged on the right and left side of the lumbar region, maintaining a distance of 5 to 10 cm between them, with the patient lying in the dorsal decubitus position
Device: Pilates and Shortwave active
Pilates exercises and application of the device producing thermal effects

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
Change in pain through Pain visual analogue scale
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
Scale with 11 centimeters is used for evaluate pain intensity, being "0" no pain and "10" the worst possible pain
Before the treatment, up to 3, 6 and 18 weeks
Change in pain through The McGill pain questionnaire
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
It is organized in four categories: sensory, affective, evaluative and mixed, with 20 subcategories and 78 words descriptors of pain, describing the quality of pain. The pain evaluation index is the sum of the values added, and each word chosen in each dimension is the maximum score of each category: Sensory = 34, Affective = 17, Evaluative = 5, Mixed = 11, Total = 67.
Before the treatment, up to 3, 6 and 18 weeks

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
Functional disability
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
The Rolland and Morris Questionnaire, validated in Brazil, will quantify the functional limitations caused by low back pain. The questionnaire is composed of 24 questions related to normal activities of daily living, in which each affirmative answer corresponds to a point. The final score is determined by the sum of the values obtained. Values close to zero represent the best results (lower limitation), and values close to 24 the worst results. Values above 14 points are considered as a severe spinal impairment.
Before the treatment, up to 3, 6 and 18 weeks
Patients' perceptions of their health-related quality of life: The Short-Form Health Survey questionnaire (SF-36)
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
The Short-Form Health Survey questionnaire (SF-36) will assess the health-related quality of life of patients. This instrument contains 36 questions grouped into eight areas: functional capacity (10 items), physical aspects (2 items), pain (2 items), general state of health (5 items), vitality (4 items), social aspects (2 items), emotional (3 items) and mental health (5 items). The values in each domain vary from 0 to 100 and, more indicate a better quality of life.
Before the treatment, up to 3, 6 and 18 weeks
Perception of global effect
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
Evaluates the level of perception of patient recovery through a Scale Numbers of 11 points comparing the onset of symptoms at the beginning of treatment in relation to the last days. It varies from -5 to +5, being -5: extremely worse; zero: no modification; and +5: fully recovered, with the highest score representing greater recovery.
Before the treatment, up to 3, 6 and 18 weeks
Emotional Functioning
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
It will be evaluated by the Brazilian version of the Visual Analog Scale for anxiety. Analogic visual scale for anxiety is a horizontal line of 100 mm in length. The tip left without anxiety and the right tip means worse anxiety.
Before the treatment, up to 3, 6 and 18 weeks
Depressive Symptom
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
It will be evaluated by the Brazilian version of the Beck Depression Inventory, a self-assessment measure of depression. It is a questionnaire with 21 items whose intensity ranges from 0 to 3 points. Largest scores indicate more depressive symptoms.
Before the treatment, up to 3, 6 and 18 weeks
Symptoms and adverse events
Time Frame: Before the treatment, up to 3, 6 and 18 weeks
The record of the symptoms and adverse events that occurred during the established behavior will be captured passively through spontaneous reports of the patient. The active catch will use a questionnaire with a record of the duration and intensity of the adverse symptom reported by the patient. You will then be asked to the patient graduates the certainty of their affirmations according to a Likert scale (being 1 not certain and 5 total certainty).
Before the treatment, up to 3, 6 and 18 weeks
Patient Satisfaction: The MedRisk scale
Time Frame: Patients will be evaluated up to 6 weeks
The MedRisk scale consists of 20 items, 10 items related to the therapist-patient interaction; 8 items involving evaluation of the infrastructure and work organization of the physical therapy clinic and 2 items that are considered as global evaluation of the treatment. The patient elects level of satisfaction in each item by selecting a Likert scale ranging from 1 "completely disagree" to 5 "agree completely" or through an option "not applicable", with high scores representing high satisfaction.
Patients will be evaluated up to 6 weeks
