Descrição detalhada
This study is a placebo controlled Randomized Clinical Trial (RCT) in which the primary outcome is to determine whether Extracorporeal Focused Shock Wave Therapy (ESWT) reduces knee pain comparing the VAS at baseline and one month after the end of the treatment. Function assessment and progression of pain along the treatment are the secondary outcomes. Function will be assessed with the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC), the Lequesne's Algofunctional Questionnaire for Osteoarthritis of Knee (Lequesne) and the Timed up and Go (TUG).
The ESWT applications will be performed once a week for four consecutive weeks, the patients will be assessed for pain and function before the beginning of the treatment and one week after every application of the ESWT.
The treatment groups will be randomized. The allocation of the patients is sealed and will not be disclosed to the patients nor to the evaluators.

Armas e Intervenções
Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: Extracorporeal Shock Waves
Focused shock waves delivered by an electromagnetic generator with a focus of 5.0cm deep on the affected knee in three different positions.
A total of 7000 pulses will be delivered on a weekly session for four weeks.
|
Patients receive instructions for physical activities for strengthening of femoral quadriceps and stretching of hamstring muscles.
|
|
Comparador Falso: Sham Extracorporeal Shock Waves
Sham focused shock waves delivered by an electromagnetic generator on the affected knee in three different positions.
A total of 7000 pulses will be delivered on a weekly session for four weeks.
A foam will be placed in the probe as to stop the energy to be transmitted to the patient's knee, so no focused shockwaves will be delivered.
