Research conclusions
BLOOD
(1) Blood flow restriction, combined with low-intensity quadriceps training, can effectively improve the knee extensor muscle strength and girth of patients with ACLR.(2) Blood flow restriction, combined with low-intensity quadriceps training, can help reduce the difference between the affected and normal sides of the knee joint of ACLR patients and improve knee function, which can accelerate the patients’ rehabilitation process and help them enter the next rehabilitation cycle as soon as possible.(3) The level of compression has a clear effect on the muscle strength, circumference, bilateral knee joint differences, and knee function recovery of patients during mid-term ACLR. If we do not consider the discomfort involved in the process of pressure training, the maximum benefit can be achieved by choosing an 80% AOP compression intensity for quadriceps femoris training.
