Factors Affecting Clinical Decision Making for Blood Flow Restriction Training in Pediatric and Adolescent Patients Following Anterior Cruciate Ligament Injury.
Nicholas Giampetruzzi, Lauren S Butler, Jennifer Prue and 1 others
Most PTs let pain level, knee swelling, and time from surgery drive their BFRT decisions in kids and teens after ACLR, but 55% won't use it on younger patients and only half have a rule for when to stop.
There is no consensus on timing or discontinuation criteria.
Key findings
1Pain was the strongest practical barrier: 88% would use BFRT at a pain rating of 1–3/10, 64% at 4–6/10, but only 19% at greater than 6/10, even though 71% said pain influenced their decision.
255% of PTs would not use BFRT on younger patients; among those, 90% cited patient tolerance concerns and 79% cited fear or anxiety, while only 15% raised open growth plates as a worry.
3Only 52% had defined criteria for stopping BFRT. Among those, limb symmetry index thresholds were scattered: 18% stopped at >70% LSI, 37% at >80%, and 33% at >90%, with no single standard.

What it does not show
The survey instrument had no reliability or content-validity analysis, so it is unclear whether all respondents interpreted the vignettes the same way. Recruitment ran through BFRT continuing-education channels and social-media snowballing; 70% of respondents had taken formal BFRT coursework and 66% of those took it through a single provider (Owens Recovery Science), so the sample skews toward PTs already invested in BFRT. The vignettes did not specify the BFRT cuff system, width, or pressure, and did not include any physeal-stress monitoring protocol, so responses may reflect assumptions rather than actual practice. The survey captured what PTs said they would do, not what they actually do, and could not probe the clinical reasoning behind each choice. Convenience and snowball sampling limit how far the findings can be generalised to all PTs treating pediatric ACLR.
Declared interests
The three survey developers were all BFRT-certified (two through Owens Recovery Science, one through Smart Tools). The survey was distributed through continuing-education providers, and 66% of respondents who had taken BFRT coursework had taken it through Owens Recovery Science. No separate funding or conflict-of-interest declaration appears in the text provided.
The easy way to misread this
Do not read these percentages as evidence about what BFRT should or should not do in a given patient. This is a survey of what PTs say they would do, not a test of BFRT's effect on strength, pain, or recovery. The sample is also heavily skewed toward PTs who already use BFRT (70% had formal training), so the 'consensus' you see here is the consensus of a self-selected, trained subgroup, not of the profession as a whole.
