Now FDA cleared
Because for a child, walking is more than getting around.
What Trexo Theo is
Trexo Theo is a wearable robotic exoskeleton that moves a child's legs through a real gait cycle, over the ground, at their own pace. Not a simulation of walking. Walking.
One device, fitted to your child, used at home, outdoors and in clinic under the supervision of a certified companion or therapist.
Every step is intentional
Clinical evidence
Real-world walking. Published experience.
171
participants enrolled
171 children and young adults enrolled in a six-month observational study of Trexo use at home and in the community, with device use tracked month by month.
Six-month observational study · ages 1–24
150
min/week, median
In a 12-week family-led program, 15 completers walked a median 150 minutes and about 7,500 steps per week. Parents also reported progress toward individual goals.
Single-group program · ages 4–23
99%
median walking time
In a single-session study of 15 participants, a median 99% of robotic walking time met the threshold for physical activity: at least light activity, measured by heart rate.
Single-session measurement · ages 5–24
These observational and single-group studies include ages 1–24, many under 12, and varied diagnoses. The US indication is ages 12 and older with cerebral palsy. Individual results vary.

Steps aren't just distance. They're dose.
Updated live from the Trexo fleet. One trip around the Earth is measured along the equator: about 50 million steps.
Adapts to your child
Theo is configured to each child's ability and goals. From kids who can already initiate steps to those who need full support, the same device adjusts mode, accessories and assistance.
For kids who can already initiate steps. Theo follows their movement and completes the stride, so the effort is theirs and the steps add up.
For kids who need significant help to walk. Theo provides the structure and part of the drive, and the assistance level moves as they do.
For kids who cannot bear weight or step on their own. Theo carries the work of walking while they stay upright, moving over real ground.
For clinicians
Every session records steps, speed and assistance, so over-ground gait training becomes something you can track, adjust and document. One device serves a caseload across four sizes and the full range of support.

Why we built it
Manmeet Maggu and his nephew Praneit, the inspiration behind Trexo.
Individual experiences are not a prediction of another child's results.
“Watching Praneit take his first steps using our device was an incredibly proud moment for us.”
Trexo started as two engineers building a device for one child. Today, kids in a Trexo have taken well over a hundred million steps, and the same device is now cleared for families and clinics across the United States.
FAQ
Short answers first. Our US team can go deeper on any of them.
Ask us something elseYes. Trexo Theo received 510(k) clearance from the FDA. The full Indication for Use is printed at the bottom of this page.
Trexo Theo is indicated for patients 12 years and older with cerebral palsy. It is a prescription device: a physician orders it and our clinical team confirms fit, sizing and any contraindications before delivery.
Yes. Theo is intended for community use under the supervision of a trained companion, usually a parent, who completes Trexo's companion certification. The same device is used in clinics under a certified therapist.
In the US, Theo is currently cleared for ages 12 and up with cerebral palsy. If your child falls outside that, talk to our team: we can tell you what's possible today and keep you informed as the indication evolves.
Four sizes, fitted to hip-to-knee and knee-to-floor length and adjustable as your child grows, up to 150 lb. Your child's therapist takes the measurements during the assessment and our clinical team confirms the size before the device is built. The sizing chart shows the ranges.
Most families walk several times a week. A session is set up by the certified companion or therapist: mode, assistance level, speed and prompts are configured to the child, and every step is recorded.
