Participation is voluntary and participants have full legal capacity and understand the nature, scope, importance and consequences of the investigation;

diagnosed knee osteoarthritis stages (radiography), clinically screened and confirmed beforehand

Exclusion Criteria

1. medication modifying pain perception and proprioception in the last 48 hour
2. Serious diseases that affect participants quality of life (psychological, neurological, cardiopulmonary, endocrine or metabolic)
3. Pregnancy or breastfeeding
4. acute inflammation of the knee joint

Study & Design

• Study Type: interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
knee joint sounds are measured before and after both interventions using vibroarthrography (acoustic sensors, amplitude in dB and frequency in Hz), sensors are placed at the medial tibial plateau and the patella

Secondary Outcome Measures

Name	Time	Method
acute knee pain (before measurement, during pre-measurement, during intervention, during post-measurement and after measurement) using Visual Analogue Scale (VAS) (score of 10 cm)
