Summary

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.

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.

Conditions

• Renal Insufficiency, Chronic
• Renal Dialysis

Interventions

Type	Name	Description
OTHER	Photobiomodulation	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.
