A smart knee brace that brings post-surgery physical therapy back home — at the right angle, for the right duration, under your physiotherapist's remote watch. The patient is no longer alone, the clinician is no longer blind.
After knee surgery, 70% of recovery depends on the physical therapy patients perform at home. Yet there is no tool to measure form, and no eye to verify it.
Existing CPM devices are bulky, expensive, and clinic-bound; they offer only passive motion. Conventional braces are "dumb" — no feedback at all. Pain scales like the VAS are subjective — just a number in the patient's head.
A medical neoprene brace augmented with a dual-IMU motion array, secure wireless connectivity, and three signal LEDs. The system measures knee angle in real time, signals correctness through color, and streams session data to the physiotherapist.
The motion is within the target angle range. A silent confirmation is given; the screen prompts "keep going". The patient continues with confidence.
Angle is out of range or speed is too high. A short vibration accompanies the alert; the patient corrects posture immediately.
The exercise set is finished. A steady blue light holds for three seconds; session data is delivered to the clinician's dashboard.
One sensor sits near the vastus lateralis (thigh), the other near the peroneus longus (calf). The system continuously tracks the knee angle between -90° (full flexion) and 0° (full extension).
PROTOTYPE · ITU FACULTY OF TEXTILE TECHNOLOGIES & DESIGN
"Knee not held straight" — angle outside target range
"Knee straightened" — 0° target reached
20-second hold achieved — set finished successfully
"Knee bent at 90°" — -90° target reached
20× lighter than a CPM device, far more intelligent than a conventional brace. Data flows. Movement is learned.
Two synchronised inertial sensors on thigh and calf capture knee kinematics in real time.
Encrypted data flow links the brace to the patient app and clinician dashboard.
±1° accuracy at 44 Hz sampling, from full extension to full flexion.
Patella-open neoprene brace plus electronics — 20× lighter than CPM units.
Patent, peer-reviewed publication, and a TRL 6 prototype — all together. Science is an inseparable part of our brand identity.
