Not Applicable

Not yet recruiting

• Conditions: Osteoarthritis of the Knee
• Interventions: Other: Low impact immersion; Other: High intensity aquatic physiotherapy; Other: Conventional aquatic physiotherapy

• Registration Number: NCT05610696
• Lead Sponsor: Federal University of Health Science of Porto Alegre

Brief Summary

The aim of this study is to evaluate the effects of different modalities of aquatic physiotherapy on the biochemical and functional behavior of patients with knee's Osteoarthritis.

Detailed Description

The subjects will be informed about the study and its potentials risks and sign the informed consent. The sample will be submitted to three different modalities of AF interventions: (a) low impact immersion, (b) conventional aquatic physiotherapy and (c) high intensity aquatic physiotherapy. The functional variables of flexibility, pain, joint volume will be evaluated before and immediately after each intervention whereas the biochemical variables will be evaluated from the analysis of peripheral blood following times: baseline moment (immediately before the intervention), moment 1 (immediately after the intervention), and moment 2 (24 hours after the intervention).

Arm && Interventions

Group	Intervention	Description
Low impact immersion	Low impact immersion	This intervention will use the principles of Ai Chi, a model defined as a low-intensity aquatic exercise strategy
High intensity aquatic physiotherapy	High intensity aquatic physiotherapy	In this intervention, high-impact exercises will be performed, with maximum movement speed, twice time of the medium-intensity protocol
Conventional aquatic physiotherapy	Conventional aquatic physiotherapy	In this intervention, medium impact exercises will be performed, with a comfortable movement speed.

Primary Outcome Measures

Name	Time	Method
Biochemical variables over time	Baseline moment (immediately before the intervention), moment 1 (immediately after the intervention) measured in all interventions in mg/mL	Variations in the concentration of Metalloproetinase

Secondary Outcome Measures

Name	Time	Method
Muscle strength over time	Baseline moment (immediately before the intervention), moment 1 (immediately after the intervention) measured in all interventions.	Measured by dynamometer to assess knee extension strength. Results expressed in kg of force.
Degree of pain over time	Baseline moment (immediately before the intervention), moment 1 (immediately after the intervention) measured in all interventions.	Performed using the visual analogue pain scale, from a scale graduated from zero to 10, in which zero corresponds to cases without pain and 10 corresponds to the worst imaginable pain.
Edema over time	Baseline moment (immediately before the intervention), moment 1 (immediately after the intervention)	Performed based on the measurement of the circumference of the affected knee. Result expressed in centimeters
Flexibility over time	Baseline moment (immediately before the intervention), moment 1 (immediately after the intervention) measured in all interventions.	Assessed by measuring the amplitude of the active and passive movement for the knee flexion and, for that, a conventional goniometer will be used. Result expressed in degrees
