“…A recent review and retrospective analysis demonstrated concerns with using estimation formulas in the lower body (Loenneke et al 2015, Yamada et al 2023. Previous estimation equations were not developed on individuals with arterial occlusion pressure over 300 mmHg.…”

“…Estimation equations could potentially remedy this issue as well as help those who do not have access to the necessary equipment to measure arterial occlusion pressure (Jessee et al 2016, Loenneke et al 2015. However, these estimation equations may be limited by the equipment used to derive them (Yamada et al 2023). Due to the upper pressure limit (300 mmHg) of the cuff inflator system (Hokanson rapid inflation system), the equation is not accurate when the individual's arterial occlusion pressure is greater than 300 mmHg (Yamada et al 2023).…”

Blood flow restriction pressures are set relative to the lowest pressure needed to occlude blood flow with that specific cuff. Due to pressure limitations of some devices, it is often not possible to occlude blood flow in all subjects and apply a known relative pressure in the lower body with a 5 cm wide cuff. Objective: To use a device capable of generating high pressures (up to 907 mmHg) to create and validate an estimation equation for the 5 cm cuff in the lower body using a 12 cm cuff.Approach: 170 participants had their arterial occlusion pressure (AOP) with a 5 cm and 12 cm cuff and their thigh circumference measured in their right leg. The sample was randomly allocated to a prediction group (66%) and validation group (33%). Thigh circumference and 12 cm AOP were used as predictors. A Bland-Altman plot was constructed to assess agreement between measured and predicted values. Main results: The mean difference (95% confidence interval) between the observed (336.8 mmHg) and the predicted (343.9 mmHg) 5 cm AOP was 7.1 (-11.9, 26.1) mmHg. The 95% limits of agreement were -133.6 to 147.8 mmHg. There was a negative relationship between the difference and the average of predicted and measured 5 cm AOP (B= -0.137, p=0.000043). Significance: Although this was the first study to quantify AOP over 600 mmHg with a 5 cm cuff, our equation is not valid across all levels of pressure. If possible, larger cuff widths should be employed in the lower body.
