How Reflex Works

A guided session at home, measured on the device, reviewed by the care team.

The short version

Rehab happens at home. Reflex goes there.

Most of the work of recovering from knee surgery happens between appointments, in a living room, alone. Reflex is built for that stretch: it guides the session, records what actually happened, and hands the care team something better than a recollection at the next visit.

The device is worn on the leg, weighs less than five pounds, and runs its exercises from a simple on-board interface. Nothing has to be set up on a phone or a laptop for a session to start.

The Recovery Loop

Four steps that repeat for as long as the program runs

Step 1

Prescribed and set up

The care team puts a program on the device: which exercises, through what range, how often. The patient takes it home ready to use.

Step 2

Guided sessions

Reflex walks the patient through each exercise step by step, with difficulty that adapts as recovery progresses. No interpretation of a printed handout required.

Step 3

Measured on the device

Range of motion, strength, adherence and progress are tracked continuously as the session runs, then sent over WiFi.

Step 4

Adjusted remotely

The clinician reviews what came back and changes the program without waiting for the next appointment, or bringing the patient in for one.

The device

What is on the leg

Reflex is a robotic knee brace, not a tracker strapped to one. It moves with the exercise rather than only counting it.

  • Under five pounds
  • Simple on-board interface, no phone required to run a session
  • WiFi enabled, for monitoring and remote program changes
  • Telehealth enabled biometric monitoring
  • FDA Listed

Used Under a Clinician’s Direction

Reflex supports a rehabilitation program. It does not replace one.

A Reflex program is set by the treating clinician, and the exercises, ranges and progression stay theirs to decide. What the device changes is how much of the recovery they can see, and how quickly they can act on it.

Reflex is FDA Listed. Listing is a registration step with the U.S. Food and Drug Administration, and it is not the same thing as a clearance or an approval. Nothing on this site should be read as medical advice, or as a claim about the outcome of any individual recovery.
