Osteoarthritis (OA) of the Knee, Muscle Atrophy
Conditions
Brief summary
The present study investigates the effects of blood flow restriction training on muscular recovery during out-patient rehabilitation after elective total knee arthroplasty
Detailed description
The present study evaluated the impact of blood flow restriction training in the context of three-week outpatient rehabilitation following TKA, in accordance with the guidelines of the German Pension Insurance System. The in-rehabilitation and post-rehabilitation muscle status, strength, knee functionality, impairments in daily life and subjective pain perception were measured.
Interventions
PROCEDURESham-BFR
The exercise protocol for the operated leg (with sham pressure of 20mmHg) consisted of four sets with 75 repetitions (reps) in total (1. Set: 30 reps, 2.-4. Set: 15 reps) with 30% of the individual one-repetition maximum for each exercise and were performed five times per week during the three-week outpatient rehabilitation.
PROCEDUREBlood Flow Restriction Training
The exercise protocol for the operated leg (with a BFR pressure of 60% of the LOP) consisted of four sets with 75 repetitions (reps) in total (1. Set: 30 reps, 2.-4. Set: 15 reps) with 30% of the individual one-repetition maximum for each exercise and were performed five times per week during the three-week outpatient rehabilitation.
