For Effective Safe & Convenient BFR consider which type of cuff that fits You or Your clients the best.

The cuff shape and width is important for comfort, to reduce mechanical shearing during exercise and more efficient transmission of pressure…

Thighs comes in various sizes and shapes. Though, most are conically i.e., tapered, particularly in muscular or plumper individuals which would best match the cone shape of the Leg Cuff V3. On the other hand, slender – less muscular or longer thighs would also have a decent fit with the V2’s.

The V3 can be adjusted to the shape of the limb by an arc-shaped design that, when attached correctly allows for a customizable fit by a an adjustable smaller diameter distally compared to proximally.

This design simply allows the user to adapt the shape of the cuff to a wider range of thigh shapes:

The narrowing triangle velcro-strap allows the proximal and distal circumferences to be adjusted, allowing the cuff to conform to a variety of cones, to accommodate different thigh shapes, as shown in the figure above (2. image).

You can test the fit during attachment before inflation by placing 4 fingers between the cuff and the thigh distally and proximally, aiming for similar tightness.

Final Considerations.

The Leg Cuff V3 is a state-of-the-art designed variable-contour cuff developed to better match different thigh shapes, and thereby provide more efficient pressure distribution, which enables less pressures to be used.

V3 is a single bladder cuff designed to safely restrict blood flow as either full occlusion i.e., 100% Limb Occlusion Pressure (LOP) or to decrease blood flow (40-90% LOP) by applying evenly distributed circumferential pressure around the thigh.

The internal stiffener helps direct the pressure exerted by the bladder inward towards the thigh, and helps maintain the cuff in a stable position during exercise. The nylon stabilizer is used during cuff attachment and helps prevent the cuff from shifting on the thigh during exercise.

As a rule of thumb, the V2 is designed to fit optimally on cylindrically aka. straight thighs. V3 which is contoured in order to form a cone during attachment, would probably be a better fit for approximately >70% of people. And remember, both Cuffs are applicable for thigh sizes 45->85 cm.
