Summary

This project aims to investigate the feasibility of a low load (LL) isokinetic knee flexor and extensor strength training (ST) protocol under blood flow restriction (BFR) conditions in early postoperative total knee arthroplasty patients.

The intervention consists in testing an experimental strengthening protocol in the Leukerbad Clinic. 12 participants will be recruited and the intervention will last approximatively 3 weeks and will consist in 3 weekly ST.

The collected data will then be analysed and interpreted to define if such an intervention is feasible or not.

PROCEDURE

Low Load Strength Training under Blood Flow Restriction

The first training includes one initiation/warm up set and two sets of normal training. Every set lasts 60 seconds and the patient is asked to bend and stretch the knee with a standard speed of 20°/s. From the second to the ninth training, the patient will have one warm up set plus three trainings sets. The speed of execution will be increased every training. The 20-40% range of the 1RM will be applied according to the values of the theoretical maximal strength. If no strength progression is observed in the three last training sessions, the speed of execution will automatically be increased by 15°/s. In order to keep the training intensity low and to not overload the knee, participants will be instructed to control the intensity with the Borg CR10. The volunteers will have to keep their efforts between 2/10 and 4/10. They will also be asked to stay in the range defined thanks to the theoretical maximal strength shown by the screen.
