Blood Flow Restriction for Upper Limb Rehabilitation in People With Multiple Sclerosis. A Randomized Controlled Trial (BFRT-EM)

"The experimental group will perform a low-intensity strengthening program (20% 1RM) in combination with the BFRT system consisting of the following exercises: palmar flexion and dorsal flexion; ulnar deviation and radial deviation; pronation and supination; elbow flexion and extension, performing 4 sets of 30/15/15/15 repetitions as usual in this type of interventions.~Once the first exercise has been completed, a rest of 3 - 4 minutes should be taken depending on the fatigue perceived by the patient. Subsequently, the other two exercises will be performed following the scheme already outlined.~Taking into account the scientific evidence concerning the safety and adverse effects linked to the BFRT system, it is determined that the pressure applied in the experimental protocol will be 60% of the TRP of each subject, following the recommendations that locate the effective pressure between 50 - 80% of the TRP of each subject."

The control group will perform a conventional muscle strengthening protocol consisting of the following exercises: palmar flexion and dorsal flexion; ulnar deviation and radial deviation; pronation and supination; elbow flexion and extension, with a dumbbell at 70% of 1RM, performing a total of 4 sets of 8 - 12 repetitions each, avoiding muscle failure in each set.
