The flagship instrumentIn validation
Reach
Reach is a movement-tracking instrument for stroke recovery… a precise, camera-based system that watches the hand and arm work, counts what matters, and turns the long repetition of rehabilitation into measured, motivating progress, at home, on an ordinary laptop.
01
The problem it addresses
Inpatient rehabilitation works, and the field understands why: clinician guidance, structured repetition, immediate feedback, and sustained motivation form a loop that drives recovery. At home, most of that scaffolding disappears. The exercises continue, but the feedback, the measurement, and the encouragement do not… and at-home recovery suffers for it.
Reach is built to supply exactly that missing layer: precise movement feedback, visible progress, structured repetition, and motivation engineered into every session… the elements of the inpatient loop that clinicians have not been able to send home with their patients.
02
How it works
Reach uses on-device computer vision to track hand, finger, and arm movement through a standard webcam… no wearables, no special hardware. It measures the work at the level that matters: individual finger extension, grip and release, range of motion, reach-and-return.
It is exact about quality, not just quantity. Repetitions count only when the movement is done well, and the system watches for the compensations, like trunk lean, that quietly undermine recovery. Sessions are recorded as structured progress over time.
All processing happens on the device. No video leaves the machine.
A sea of signals, and a light to navigate it by… the instrument thesis, painted.
03
Built with clinicians, in a real cohort
Reach is being developed in collaboration with neuroscience and rehabilitation researchers and clinicians (described here, not named, until consents clear), whose guidance shapes what the instrument measures and how progress is presented. That validation is in progress.
The collaboration is real, and it runs in layers. Reach was independently evaluated by a neuroscience research lab at a Canadian university and pulled into its work; its measurement is being validated against the gold-standard motion-capture and hand-tracking reference standards those labs use to study movement; there is a clinical pathway through a hospital stroke unit; and the whole effort runs under a research-ethics protocol, inside a national neuroscience research network, with a structured validation vehicle underway. A growing team builds it across multiple systems.
That is the standard the instrument is being built and validated to: clinical-grade, taken all the way to full clinical and regulatory compliance. Not a finished clinical claim yet, the bar it is held to.
The instrument is grounded in recovery science: the well-established evidence that feedback, repetition, and motivation are central to motor recovery.
04
The hope layer, built in
Recovery is not only mechanical. People stall when they cannot see that the work is working, and they keep going when they can… and when they know someone else made it through. Reach is being built so that progress is visible and so that encouragement has a place in the loop: the lived truth that someone who has walked this road can carry someone who is still on it.
Hope and belief are not decoration here. They are a designed part of the instrument, held to the same honesty as everything else… grounded, never a promise of cure. Reach never claims belief changes the disease, only the fight, the showing-up, and the work that recovery is made of.
05
Built from inside recovery
Reach’s founder is doing this rehabilitation himself. The exercises the instrument tracks are real, prescribed ones… refined daily against the lived reality of recovery, not a hypothesis about it. That is not a story attached to the product. It is the design process.
06
Where Reach stands
Where it stands today: an active prototype, in deep development and validation, being taken all the way to full clinical and regulatory compliance. A working build already tracks real prescribed rehabilitation on an ordinary laptop, with access opened deliberately to clinicians and researchers, not to the public. It is not a shipped or certified product yet. The founder's own daily rehab is the first test case.
In validation: independently evaluated by a neuroscience research lab at a Canadian university and pulled into its work, validated against the gold-standard motion-capture and hand-tracking reference standards those labs use, with a clinical pathway through a hospital stroke unit, under a research-ethics protocol, inside a national neuroscience research network, built by a growing team across multiple systems.
On the roadmap: the rest of the road to full clinical and regulatory compliance, and the rest of the healing-tools suite built around it. Each is named here as it becomes real… honest about which is which.
07Posture
What this is, precisely
- Reach is an independent Lighthouse instrument, part of the healing-tools suite, developed in the open.
- It is not a medical device, and it does not diagnose, treat, or replace professional rehabilitation. It is built to work alongside a care team, supporting the at-home practice between sessions.
- Processing is on-device and privacy-first: the camera feed is analysed locally, and no video leaves the machine.
Reach is built to work alongside professional care, never in place of it. Decisions about rehabilitation belong with you and your care team.
Reach is the first proof of the Lighthouse thesis at its hardest test: that hope can be engineered… that belief can be built into an instrument precise enough to matter.
