View attachment 46778View attachment 46779We take a percussion massager, set it to mode 2 (the frequency should not exceed 25-30 Hz), and apply the percussion massager to the side indicated by the red line. This is necessary to avoid cartilage injury. We follow the black lines for chondrogenesis and length growth.Low-frequency vibrations increase the thickness of the cartilage growth zone and stimulate the formation of a new cartilage matrix without significantly increasing osteogenesis, increasing the metabolic activity of chondrocytes, supporting the synthesis of type II collagen, reducing the apoptosis of chondrocytes, and increasing the expression of SOX9 and BMP-2(Unfortunately, the studies are only in vitro, so this technique is only a hypothesis. However, considering how the leg bones elongate due to other mechanical stimuli, it is likely that vibrations have a good potential)
