Key features
SmartCuffs 4.0 uses individualized limb occlusion pressure calibration and multiple pressure modes. The manufacturer describes continuous, intermittent and resting BFR modes for different training and rehabilitation applications.
- Provides individualized pressure calibration rather than a one-size-fits-all setting.
- Wireless design with built-in pumps simplifies setup.
- Multiple BFR modes allow different training and recovery approaches.
- Bluetooth connectivity supports control and tracking through the SmartCuffs app.
How it fits into your recovery
BFR is most useful during a specific rehabilitation or training block. Renting means you can follow that block properly without owning a system you will not need afterwards.
| Guided rehabilitation | Directed by a provider or qualified professional |
|---|---|
| Low-load strength work | When heavy loading is not appropriate yet |
| De-loading joints | During rehabilitation from a joint injury |
| Structured training programs | Where BFR is already part of the plan |
What renting this actually looks like
Five stages, and a person at Caliber involved in four of them. This is the part that separates us from buying a box online.
Request
You pick the equipment and rental period and send a request. Nothing is charged at this point.
Prepare
We check the motor, the controller and every strap, then set the unit to a neutral starting range.
Deliver
Delivered and assembled in the room you will actually use it in, usually beside a bed or sofa.
Use
Most people run two to three sessions a day. Your provider sets your settings. We leave a quick-start card with setup steps and when to stop.
Return
Call or text to extend weekly, or book a pickup. We collect from your door.

Use only with appropriate guidance
Blood flow restriction is specialized equipment. Use SmartCuffs 4.0 according to the manufacturer's directions and under the guidance of a physician, physical therapist or other qualified professional. Review the manufacturer's contraindications and stop-use warnings before beginning a session.
Before it reaches you
The cuffs are charged, inspected and function-tested before delivery. Every rental set is cleaned between rentals, and the required accessories and manufacturer instructions are checked before it leaves Caliber.
Targeted Recovery
Most people rent the Kinetec Spectra Knee CPM alongside the Breg Polar Care Wave. Together they are priced as a set.
