[Blood-flow restricted walking exercise as rehabilitation for a patient with chronic knee osteoarthritis].

In this case report, a 75-year-old woman with symptomatic knee osteoarthritis completed nine weeks (27 sessions, nine supervised) of blood-flow restricted (BFR) walking exercise without any discomfort and a 100% training adherence. BFR walking was well tolerated by the patient and resulted in improvements in functional capacity: 30-sec. sit-to-stand, timed up and go, 40-m walk test, and stair climb test. However, no positive changes were noted for maximal knee extensor and knee flexor strength or in Knee Osteoarthritis Outcome Scores.
