The Effect of Blood Flow Restriction Method in Patellar Instability

Официальное название

The Effect of Blood Flow Restriction Applied to the Extensor Muscles on Muscle Architecture and Strength, Knee Pain, and Functions in Minor Patellar Instability

Обзор

The blood flow restriction method, the effects of which have been frequently investigated in the literature in recent years, can produce muscle hypertrophy with low-intensity load and can be easily tolerated through to low mechanical stress, seems to be an exercise approach that can be used in the recovery of strength in cases with minor patellar instability and can contribute to the recovery of functional capacity without delay.

Подробное описание

Patellar instability is defined as disruption of normal movement of the patella in the trochlear groove, symptomatic, medial-lateral displacement. Patients with patellar instability may not be able to tolerate high-intensity quadriceps exercises in the early period of strengthening programs due to pain symptoms, and therefore strength recovery may be delayed. However, it is important to restore muscle strength, especially vastus medialis obliquus strength, as early as possible in patellar instability. The blood flow restriction method, the effects of which have been frequently investigated in the literature in recent years, can produce muscle hypertrophy with low-intensity load and can be easily tolerated through to low mechanical stress, seems to be an exercise approach that can be used in the recovery of strength in cases with minor patellar instability and can contribute to the recovery of functional capacity without delay.
