The IPPaM Study - Does Light-Therapy Reduce Osteoarthritis Knee Pain and Aid Willingness to Exercise?

Osteoarthritis of the knee joint

Associate Professor Liisa Laakso is testing the effectiveness of a new light-emitting adhesive patch that shines red and blue light to the knee joint and thigh muscle. Ten participants apply four “light patches” to the leg for 30 minutes a day for two weeks. Ten other participants receive no light therapy.

On several occasions throughout the study the researchers ask participants to do simple physical tests, and answer questionnaires about their pain and other symptoms.

Prof. Laakso aims to recruit 20 people to the study from the Mater Hospital Brisbane Physiotherapy waitlist.

Information from this study will inform the development of future research.
