Knee Osteoarthritis, Motor Control, Risk of Falls and Virtual Reality

The goal of this clinical trial is to learn about knee osteoarthritis, functionality, and risk of falls in community-dwelling adults aged 60 years and older. The main questions it aims to answer are: * What are the characteristics of a community-dwelling population over 60 years and older in terms of knee osteoarthritis, functionality, and risk of falls? * Does an intervention with virtual reality lower knee osteoarthritis symptoms, raise functionality and prevent falls in community-dwelling adults aged 60 years and older, compared to a control group receiving conventional physiotherapy treatment based on therapeutic exercise? Participants will: * Answer questionnaires. * Perform physical laboratory tests through a camera-based motion capture system. * Execute task-based exercises in a virtual environment through virtual reality. Researchers will compare community-dwelling adults aged 60 years and older who execute task based exercises in a virtual environment through virtual reality and community-dwelling adults aged 60 years and older receiving conventional physiotherapy treatment based on therapeutic exercise to see if virtual reality improves knee osteoarthritis symptoms, functionality, and lowers fall risk.
