Effect of Blood Flow Restriction Training on Patient With Anterior Cruciate Ligament Reconstruction

Summary

This study investigates the effects of plyometric training with blood flow restriction on muscular strength, quadriceps thickness and knee joint function in patients with muscle weakness and atrophy (quadriceps muscle and hamstring muscle) after anterior cruciate ligament reconstruction. Persons who completed a 12-week routine rehabilitation program after anterior cruciate ligament reconstruction will be included in the study. In the study group, plyometric exercises will be performed with blood flow restriction in the operated side for 8 weeks. In the control group, the same plyometric exercises will be performed without any application.

Conditions

• Anterior Cruciate Ligament Injuries
• Atrophy
• Muscle Weakness

Plyometric exercise with blood flow restriction

Blood flow restriction training is an exercise protocol based on the method of limiting blood flow with external pressure by pneumatic tourniquet from the proximal of the muscle to be strengthened. Blood flow restriction (Occlusion) during pliometric exercises for 8 weeks, a pneumatic tourniquet (Kaatsu Master) proximal to the thigh will be applied to each patient within a safe pressure range. The pressure to be applied to the patient will be calculated with the following formula described in the literature. Pressure = 0.5 x (systolic blood pressure) + 2 x (thigh circumference) + 5 Application will be done for a maximum of 15 minutes, then rest for 10-15 minutes and other exercises will continue. Plyometric training with blood flow restriction. Jump in functional squat system (30+15+15+15= 75 rep) Lunge jump (30 rep) Side jump (30 rep) Box jump (15 rep) Exercises to be added after 4 weeks; Square jump (15 rep) One leg hop (15 rep)
