Late-initiated Blood Flow Restricted Rehabilitation Exercises After Total Knee Replacement

Mit akar kideríteni a vizsgálat

This trial will investigate the effectiveness of applying low-load blood flow restricted exercise 12 months after receiving a total knee replacement to achieve a functional capacity-level similar to healthy peers. Participants will be allocated to either an exercise group performing a sit-to-stand exercise 4/weekly with concurrent partial restriction of the blood flow to the limbs or a usual care.

• home-based BFREA vizsgált kezelés

  Patients in the home-based BFRE group will be carefully instructed in how to perform the exercise program with four weekly sessions for 12 weeks (48 training sessions within an 84-day period). Each session will consist of one lower-limb resistance training exercise: sit-to-stand from a \~43 cm high chair. The exercise will consist of four rounds interspaced by a 30-seconds rest pause. The first, second, and third round will consist of 30, 15, 15 repetitions, while the fourth round will be performed until volitional fatigue. The patients will be instructed to perform both the eccentric and concentric contractions at a steady 2-sec pace with, preferably, no time for relaxation in the transition from eccentric to concentric phase (i.e. the bottom is only "kissing" the chair before reversing the movement upwards). When a patient can perform more than 25 repetitions in the last round, they are encouraged to add external resistance corresponding to around 5 kg.

  Patients in the control group will performed the same tests 12 months after surgery and 15 months after surgery as the intervention home-based BFRE group.
