There is little difference between 6mm and 8mm fasciotomy. There is only a gap of 22 mm between 6mm and 8mm fasciotomy, but fasciotomy has a good maintenance and relaxation effect on small parts such as forearm, fingers, neck, joints and ankles. For large area muscles, it can improve the nerve perception of body surface muscles and increase the efficiency of muscle training. There is little difference in different regions, and the effect is the same.
