Post-surgery Muscle Preservation and Pain Reduction Through Blood Flow Restriction Training in Orthopedic Spinal Surgery
Sponsor: University Hospital, Bonn
Summary
This project investigates the effects of the Blood-Flow-Restriction (BFR) training method on postoperative muscle atrophy and pain after spinal surgery. Two groups are formed for this purpose. The intervention group receives a everyday BFR training during the postoperative stay at an individually measured occlusion pressure of 60-80%. The control group performs sham-BFR training at a fixed occlusion pressure of 20mmHg. The examinations are carried out before and several times after the operation (longest follow-up: 6 months). Among other things, muscle mass, muscle strength, pain perception and quality of life are assessed using questionnaires.

Interventions
Blood-Flow-Restriction Training
For the pBFR intervention, the Personalized Tourniquet System for Blood Flow Restriction from Delfi Medical Innovations Inc. (Vancouver, Canada) were used. The cuffs were applied to both lower extremities as far proximally as possible and were connected to the control device. Before starting the training program, the individual LOP was measured of both lower limb in a restring, laying position by the control device. The Intervention-Group performed the training at 80% of their individual LOP. The training was performed alternately on both lower extremities. The time intervals were set at five minutes occlusion and five minutes rest. Each leg received five intervals of BFR-induced occlusion training, resulting in a total 50 minutes of daily training. During the entire training period, the patient was in a resting position, laying in the hospital bed.
Sham-BFR
For the sham-BFR intervention, the Personalized Tourniquet System for Blood Flow Restriction from Delfi Medical Innovations Inc. (Vancouver, Canada) were used. The cuffs were applied to both lower extremities as far proximally as possible and were connected to the control device. Before starting the training program, the individual LOP was measured of both lower limb in a restring, laying position by the control device. The Control-Group was trained with a fixed pressure of 20 mmHg, independent of their individual LOP. The training was performed alternately on both lower extremities. The time intervals were set at five minutes occlusion and five minutes rest. Each leg received five intervals of BFR-induced occlusion training, resulting in a total 50 minutes of daily training. During the entire training period, the patient was in a resting position, laying in the hospital bed.
