About this study

Official title: Acute Effect of Photobiomodulation Therapy on Quadriceps Muscle Strength in Patients With Chronic Kidney Failure on Hemodialysis: a Crossover Randomized Clinical Trial

Chronic kidney disease (CKD) consists of kidney damage and progressive and irreversible loss of kidney function. The aim of this study is to evaluate the acute effect of different doses of photobiomodulation therapy on quadriceps isometric muscle strength, pain and muscle fatigue of lower limbs and to establish the ideal dose for patients with CKD on hemodialysis. Patients will be submitted to application of photobiomodulation therapy in the quadriceps muscle. Immediately after, the maximum isometric strength test of the quadriceps will be performed.

Read the detailed description

Chronic kidney disease (CKD) consists of kidney damage and progressive and irreversible loss of kidney function. In the most advanced stage of the disease the patients require hemodialysis (HD) and present alterations such as: sarcopenia, cardiovascular disorders, increased systemic inflammation, muscle weakness and fatigue. These factors negatively affect the individual's functionality, impacting the increase in hospitalization and mortality rates. Photobiomodulation (FBM) has shown positive results in different populations on improving performance during exercise, reducing fatigue and markers of muscle damage. The aim of this study is to evaluate the acute effect of FBM therapy on quadriceps muscle strength, pain and muscle fatigue in patients with CKD on HD and to establish the ideal therapeutic dose. Patients will be submitted to application of four applications with different doses of FBM (30J, 60J, 90J and placebo) in the quadriceps muscle, in random order and one week interval between them for washout. Patients and evaluators will be blinded to the intervention protocol. The following assessments will be performed prior to FBM: subjective perception of exertion (by modified Borg scale), muscle fatigue (by analysis of blood lactate) and pain perception (by numeric pain scale). After the FBM application, the maximum isometric strength test of the quadriceps will be performed by dynamometry. Immediately after performing the strength test, all assessments will be repeated.

What participants receive

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

  • PhotobiomodulationOther

    Also called Low level laser therapy

    It will be applied a dose of laser radiation through a cluster with four diodes, wavelength of 830 nm and power of 800mW (200mW/diode), HTM® (model Fluence MAXX, São Paulo, Brazil). For application, the patient will be positioned in a sitting position and the treatment will be performed with the fixed probe in contact with the skin at an angle of 90º, using the continuous emission mode. The therapy will be applied to the quadriceps muscle, bilaterally.

What is being measured

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

  1. Maximal isometric muscle strength of the quadriceps

    Maximal isometric muscle strength of the quadriceps will be assessed by dynamometry.

    Measured: Immediately after the aplication of photobiomodulation therapy.

Secondary outcomes (3)
  1. Muscle pain of lower limbs

    Muscle pain of lower limbs will be assessed by the numeric pain scale (NPS). Zero means no pain and 10 maximum pain.

    Measured: Baseline and immediately after the dynamometry.

  2. Fatigue

    Fatigue of lower limbs by the modified Borg subjective perceived exertion scale Modified Borg (Borg Scale). Zero means no effort or fatigue and 10 maximum effort or fatigue.

    Measured: Baseline and immediately after the dynamometry.

  3. Fatigue

    Fatigue of lower limbs by blood lactate dosage.

    Measured: Baseline, immediately after dynamometry, at 3 and 6 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing Photobiomodulation in people with Renal Insufficiency, Chronic and Renal Dialysis, run by Federal University of Health Science of Porto Alegre 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 5 inclusion and 13 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 13 Nov 2023. 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. 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?

Maximal isometric muscle strength of the quadriceps (time frame: Immediately after the aplication of photobiomodulation therapy.). 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 13 Nov 2023.
