Abstract

Purpose: Blood Flow Restriction Therapy (BFRT) is a rehabilitation technique that seems to elicit hypertrophy gains similar to heavy resistance training. Despite increased popularity of BFRT, the extent it is used in physical therapy (PT) is unknown. The purpose of the study was to examine the knowledge, and utilization, of BFRT by practicing Physical Therapists (PTs).


Methods:  PTs were recruited to complete an online survey on their knowledge and use of BFRT.


Results: From 159 participants, it was found that 88.1% (n=140) of participating PTs had heard of BFRT, with age and gender disparities, though only 38.6% (n=54) reported using BFRT on a patient. There was a significant difference between male and female PTs knowledge (98% vs 81%, p < 0.001) and use (48% vs 24%, p = 0.016) of BFRT. 98% of PTs who reported using BFRT indicated it was beneficial or very beneficial for their patients.


Conclusions: There were apparent gaps between PTs knowledge of BFRT and inclusion in practice, though most of these clinicians would be open to consider use of BFRT. Nearly all BFRT practitioners believed it was efficacious and will continue using it. Education and training of PTs could improve utilization of BFRT and, perhaps, ultimately clinical outcomes.
