Outline of Final Research Achievements

Sensor and analysis techniques with the aim of diagnosis support system could be proposed. Signals of bending and stretching through pin type probe forced on the skin can be converted to electrical signals. From the knee joint it was also included signal of up to 18 kHz. Healthy knee, the sport knee, and the signal of knee OA knee there is a characteristic, confirmed the possibility of the diagnosis from this feature. Before and after the treatment of knee OA there is a signal change, it has been correlated with the therapeutic effect.
These factors occurred sliding surface between the tibia and femur, the surface morphology was also confirmed experimentally be involved.
