General information about equipment and published research for lab, clinic and supply staff. It is not medical advice and does not describe how to use a treadmill with any patient.
Short answer
A treadmill for rehab is a treadmill used for a medical purpose such as restoring movement or rebuilding muscle. In the United States, the FDA does not treat it as a separate “rehab” product. A mechanical treadmill is a Class I device under 21 CFR 890.5370, and a powered treadmill is a Class I device under 21 CFR 890.5380. Trial evidence on treadmill training is condition-specific; the main review covered stroke only.
Definition and scope
The FDA’s exercise-equipment regulations describe devices “intended for medical purposes, such as to redevelop muscles or restore motion to joints or for use as an adjunct treatment for obesity.” Both regulations name the treadmill as an example: “a mechanical treadmill” under 890.5370 (nonmeasuring exercise equipment) and “a powered treadmill” under 890.5380 (powered exercise equipment). The words “rehab” or “rehabilitation” do not define a separate category; what places a treadmill in these regulations is its intended medical purpose.
This page covers the equipment’s regulatory identity and the published trial evidence for treadmill training. It does not cover protocols, speeds, durations or patient selection, which belong to a treating clinician.
How the FDA classifies treadmills
The two regulations sit next to each other in the physical medicine devices part of the Code of Federal Regulations (21 CFR Part 890). The openFDA device classification database, checked 2026-10-31, lists the matching product codes.
| Type | Regulation | FDA product code | Class | Premarket notification |
|---|---|---|---|---|
| Mechanical treadmill | 21 CFR 890.5370 | IOG, “Treadmill, Mechanical” | I (general controls) | Exempt from 510(k), subject to the limitations in 890.9 |
| Powered treadmill | 21 CFR 890.5380 | IOL, “Treadmill, Powered” | I (general controls) | Exempt from 510(k), subject to the limitations in 890.9 |
The database also holds product code PKS, “Exerciser, Non-Measuring For Stroke Rehabilitation,” under 890.5370 (Class I), defined as non-measuring exercise equipment “intended for medical purposes of facilitating stroke rehabilitation and maintaining or increasing range of motion.” It shows that the regulator does use the word rehabilitation in a device definition, but inside the same exercise-equipment regulation rather than as a separate treadmill category.
Mechanical versus powered
The regulatory dividing line is whether the device is powered. A mechanical treadmill (IOG) falls under 890.5370 and a powered treadmill (IOL) under 890.5380. Related exercise devices in the same family include parallel bars (IOE), powered parallel bars (IRR), and powered exercisers (BXB). Class I means general controls apply; none of these codes is flagged as life-sustaining in the database.
What trials show about treadmill training
The most-cited synthesis is the Cochrane review by Mehrholz and colleagues, “Treadmill training and body weight support for walking after stroke” (2017 update, PubMed PMID 28815562). It pooled 56 trials with 3,105 participants (mean age 60) in inpatient and outpatient settings. Its scope is stroke only, and the results should not be read across to other conditions.
| Outcome (mean difference) | Treadmill training overall | Treadmill with body weight support |
|---|---|---|
| Walking velocity | 0.06 m/s (95% CI 0.03 to 0.09); 47 trials, 2,323 participants; moderate-quality evidence | 0.03 m/s (95% CI -0.05 to 0.10); 12 trials, 954 participants; low-quality evidence |
| Walking endurance | 14.19 m (95% CI 2.92 to 25.46); 28 trials, 1,680 participants; moderate-quality evidence | 21.64 m (95% CI -4.70 to 47.98); 10 trials, 882 participants; low-quality evidence |
For the body-weight-support column, the confidence intervals include zero, so the review did not find a statistically significant effect at the end of the scheduled follow-up. In the 38 studies (1,571 participants) in which people could already walk independently at the start, walking velocity improved by 0.08 m/s (95% CI 0.05 to 0.12).
Where it matters for labs, clinics and supply lists
- Classification on supply lists. A treadmill intended for medical purposes is a Class I exercise device under 890.5370 or 890.5380. Records that name the regulation and product code (IOG or IOL) are easier to reconcile with FDA data than a generic “rehab treadmill” line.
- Mechanical or powered. The distinction in the regulation maps to different product codes, so asset registers should record which one applies.
- Evidence claims. Material that describes a treadmill’s clinical benefit should be traced to a study population. The review above concerns people after stroke and measured walking speed and endurance, not every outcome.

Common misunderstandings
“Rehab treadmill” is a separate FDA category
It is not. The FDA codes treadmills as mechanical (IOG) or powered (IOL) exercise equipment, and the regulation applies where the intended use is medical.
Body weight support always adds benefit
In the 2017 Cochrane review, treadmill training with body weight support did not show a significant effect on walking velocity or endurance at the end of the scheduled follow-up, and the evidence was rated low quality.
Treadmill training makes people independent walkers
The review found that treadmill training did not increase the chance of walking independently (risk difference -0.00, 95% CI -0.02 to 0.02; 18 trials, 1,210 participants; low-quality evidence).
FAQ
What is a treadmill for rehab?
A treadmill used for medical purposes such as redeveloping muscles or restoring motion to joints. The FDA classifies mechanical treadmills under 21 CFR 890.5370 and powered ones under 21 CFR 890.5380, both Class I.
Did the review find adverse events with treadmill training?
The Cochrane review reported that adverse events and dropouts were not more frequent with treadmill training and were not judged clinically serious. Whether training suits a particular person is a decision for their clinician.
Does the evidence apply beyond stroke?
The review covered stroke only, so its figures should not be applied to other conditions.
