Fig. 4From: Possibilities and limits of using gyroscopic sensors in the diagnosis of progression of osteoarthritis and femoroacetabular impingement syndromeMagnitude scalogram of CWT of five footsteps of one subject with arthritis stage 2. The magnitude is represented by the color, where blue represents low magnitude and yellow represents high magnitude. More blue dots (minima of the spectrum) are emerging in the spectrum, which represent emerging resonances caused by crepitus, but it is still difficult to distinguish them from stage 1 arthritisBack to article page
