Joint pain (osteoarthritis) can be very disturbing activity and degrade performance because if it is exposed to be difficult to cure. Now the researchers can detect whether someone has the risk of joint pain to test the sound knee.

Osteoarthritis occurs when cartilage in the joints ‘sag’ and can affect any joint in the body. This joint disorder most commonly affects the hands, hips, knees, back and neck.

When osteoarthritis occurs in the knee, the cartilage that covers the ends of the bones of the knee joint is damaged. It can get worse, if the cartilage does not exist then the bones rub directly with the bone, which eventually led to tremendous pain for the patient.

Currently, there is no cure for osteoarthritis conditions, but there are few to prevent it such as weight loss or exercise can prevent stiffness. In extreme cases, surgery may be considered as a solution.

Researchers recently unveiled a prototype device that can detect knee joint pain in osteoarthritis early alias.

Researchers at the Universities of Lancaster and Central Lancashire to develop acoustic devices to scan the sound in the knee which may indicate deterioration of the knee joint at an early stage.

“Basically we have found a way to measure the noise from the joints by simple repetitive movements, which is sitting and standing,” says Professor John Goodacre of the University of Lancaster, as reported by BBC News, Sunday (18/07/2010).

Researchers found with this prototype instrument, the sound knee has its own characteristics. Characteristics of normal with a damaged knee will be detected in his voice, unfortunately not explained clearly the sound difference.

This inspired the creation of tools from industry acoustic instruments that are used to detect wear and tear. For example, to detect wear and damage in the sleeve bearing the burden of the dock.

“If we can really make a difference or if it believes that change can occur even before symptoms develop, then this will pave the way for a variety of approaches,” adds Prof. Goodacre.

When osteoarthritis has been detected early, it can at least be a change in lifestyle management, use of preventer medication or other treatment.

Professor Goodacre hope this device can later be developed into an inexpensive and practical tools, in order to use doctors and clinics to diagnose and monitor osteoarthritis.
