In this episode of The Clinical Minute, Sam Brouillette, CP, CFo, and SPS Manager of Clinical Education gives a quick overview of the latest Quattro microprocessor knee app update.
You may have received an update notification through the Quattro app. If you did not receive the notification, you can find the update in the Tools settings.
Before the update, calibration consisted of the following three steps:
Step 1: Quattro unloaded
- Knee out to the side and fully extended.
- Calibrates minimum for load and torque sensors.
Step 2: Knee loaded (Single Limb Support)
- Quattro automatically locks flexion, allows full extension.
- Middle light illuminates white.
- Ensure patient is standing single limb support upright, not leaning forward or backward.
- Calibrates maximum for load sensor.
Step 3: Walking with knee locked
- Select Ready after patient takes first prosthetic step to start the timer.
- Calibrates maximum for torque sensor.
- If the patient scuffs the toe or stops and/or turns, it may take an excessive number of steps and patient may not be able to complete calibration.
The New Update
Step 1: (Unchanged) Quattro unloaded
- Knee out to the side and fully extended.
- Calibrates minimum for load and torque sensors.
Step 2: Knee Loaded (Double Limb Support)
- Quattro automatically locks flexion, allows full extension.
- Middle light illuminates white.
- Ensure patient is standing with equal load on both limbs, not leaning forward or backward.
- Calibrates maximum for load sensor.
Step 3: Walking
- Quattro unlocks after READY button pressed.
- Allows walking with knee bending.
- Step Detect Counter.
- Can be calibrated with minimal consistent steps.
