Run the Supervision-Ratio Test
Rehabilitation robotics covers gait training, upper-limb therapy, and assistive mobility systems. These act on a patient, which places them inside the regulated device category rather than the facility equipment category.
The Bot Scout supervision-ratio test asks the question that decides clinic economics: how many patients can one therapist supervise on this device simultaneously, safely, and within the evidence base. A device that still requires one therapist per patient may improve therapy quality without changing throughput at all, and those are different business cases.
In the United States these systems are regulated by the FDA as medical devices, with each clearance tied to a specific intended-use statement covering defined conditions and patient groups.
| Evaluation | Question to answer | Who owns it | Failure if skipped |
|---|---|---|---|
| Clearance and intended use | Which conditions and patients are covered? | Regulatory and clinical lead | Off-label use without coverage |
| Clinical evidence | Which population was studied? | Therapy leadership | Evidence assumed to transfer |
| Supervision ratio | How many patients per therapist? | Clinic management | No throughput change despite capital spend |
| Setup time | Minutes to fit and configure per patient | Therapy staff | Session time consumed by setup |
| Patient fit | Height, weight, and impairment range | Clinical assessment | A device many patients cannot use |
| Service | Response time against session schedule | Biomedical engineering | Cancelled sessions during downtime |
Evidence Does Not Transfer
Clinical evidence is tied to defined conditions, severity ranges, and time-since-injury windows. A device with strong results for one population is not thereby supported for another, and vendors are rarely asked to state the boundary plainly.
Setup time is the quiet throughput killer. A device needing fifteen minutes of fitting per patient in a forty-minute session has consumed nearly half the appointment before therapy begins.
The wider category framing is in the medical robots hub and the classification boundary in the medical robot definition guide.
- Read the clearance and its intended-use statement for the exact model.
- Ask which population the clinical evidence actually covers.
- Establish the safe supervision ratio in writing.
- Time patient setup and subtract it from the session length.
- Check the patient size and impairment range the device supports.
Access and the Patient Experience
Adoption depends on patients as much as clinicians. A device that is uncomfortable, slow to fit, or intimidating will be declined, and a declined device delivers no outcomes regardless of its evidence base.
Assistive and care-support systems that do not act on a patient sit in a different category with a different owner, as covered in the robot nurse guide.

Bottom Line
Rehabilitation robots are judged on documented outcomes for a defined population at a workable supervision ratio. Verify the clearance, the evidence boundary, and the setup time before the capital case.
Establish the safe supervision ratio and per-patient setup time in writing before comparing devices.
FAQs
What are rehabilitation robots used for?
Gait training, upper-limb therapy, and assistive mobility. These act on a patient, which places them in the regulated medical device category.
Do rehabilitation robots increase clinic throughput?
Only if one therapist can safely supervise more than one patient at a time within the evidence base. Many devices improve therapy quality without changing throughput.
Does evidence for one rehabilitation device apply to another population?
No. Evidence is tied to defined conditions, severity ranges, and time-since-injury windows, and does not transfer to other patient groups without its own studies.
What is commonly overlooked when buying a rehab robot?
Per-patient setup time. A device needing fifteen minutes of fitting inside a forty-minute session consumes much of the appointment before therapy starts.
