Checked for sourced parameters, internal links and prohibited claims.
Overground gait training exoskeletons are powered or hybrid lower-limb devices used in neurorehabilitation to help patients practise walking over ground under therapist supervision. This FAQ answers the procurement questions that datasheets rarely address: which specifications are actually disclosed, which are missing, and how those gaps affect your purchase decision.
Overground gait training means walking practice on level ground, ramps or slopes rather than on a treadmill. All five systems in this database support level walking; EksoNR and Atalante X explicitly support ramps or slopes. Stair training is not supported by EksoNR or Atalante X; Indego, HAL Lower Limb and ExoMotus M4 require clinical assessment for stairs. The relevant systems are EksoNR (Ekso Bionics), HAL Lower Limb (Cyberdyne), Atalante X (Wandercraft), Indego (Parker Hannifin) and ExoMotus M4 (Fourier Intelligence).
| System | Drive | Weight | Speed | Assist torque | Lift support | Battery life | Certifications |
|---|---|---|---|---|---|---|---|
| EksoNR | Active | 23.6 kg | 1.1 km/h | 40 Nm | Not applicable | 4 h | FDA, CE |
| HAL Lower Limb | Hybrid | 17 kg | 1.5 km/h | 40 Nm | Not applicable | 3 h | CE medical, ISO 13485 |
| Atalante X | Active | 65 kg | 2.5 km/h | Unknown | 80 kg | 4 h | CE medical |
| Indego | Active | 12.3 kg | 2 km/h | Unknown | Not applicable | 4 h | FDA, CE |
| ExoMotus M4 | Active | 23.5 kg | 1.2 km/h | Unknown | Not applicable | 3 h | NMPA, CE |
All values from ExoSelect database; “Unknown” means the maker does not disclose the figure.
Three parameters are consistently missing or unverified across this dataset, and each changes the procurement calculus:
Two further gaps matter for deployment: HAL Lower Limb is offered as a lease or treatment programme rather than a capital purchase, which changes the accounting treatment; and lead times are only specified for EksoNR (8–12 weeks), with the others listed as programme-dependent or contact-maker.
Do not choose a system from this group if your procurement requires a published capital price, a disclosed peak assist force, or a fixed lead time before contract signature. None of the five vendors discloses price or peak assist force, and only EksoNR publishes a lead time. If your clinic needs stair training, exclude EksoNR and Atalante X outright—both state stairs are not supported. If you need a light device for mobile or home-adjacent use, Atalante X at 65 kg is a fixed installation, not a portable unit; Indego at 12.3 kg is the lightest in this set. If you operate in North America and require FDA clearance, HAL Lower Limb (CE medical, ISO 13485) and ExoMotus M4 (NMPA, CE) do not carry FDA in this dataset. Buyers who cannot accept undisclosed torque should restrict shortlisting to EksoNR or HAL Lower Limb until the other makers provide documented figures.
Certification is not uniform. EksoNR and Indego hold FDA and CE, covering North America and Europe. HAL Lower Limb holds CE medical and ISO 13485 but is listed for Japan, Europe and Asia-Pacific—not North America. Atalante X holds CE medical and is listed for Europe and North America. ExoMotus M4 holds NMPA and CE and is listed for Asia-Pacific, Europe and the Middle East. All five cite IEC 60601-1; Atalante X additionally cites ISO 13482. Confirm that the specific configuration you order carries the mark required in your jurisdiction—the database lists system-level certifications, not configuration-level ones.
The database records published stroke and spinal cord injury rehabilitation studies for EksoNR, clinical studies in stroke, SCI and neuromuscular conditions for HAL Lower Limb, clinical studies in neurological rehabilitation for Atalante X, peer-reviewed gait training studies for Indego, and clinical rehabilitation studies in China for ExoMotus M4. These are evidence categories, not outcome claims. Buyers should request the underlying publications and check patient populations, comparator groups and follow-up periods before treating any of them as procurement evidence.
Start with the parameters that are disclosed: weight, speed, battery life, certifications and height/user weight ranges. Then issue a documented parameter request for the three unknowns—peak assist force, peak assist torque (where unknown) and price—to every shortlisted vendor. Use the EksoNR product page and the Indego product page as reference points because they carry the most complete disclosed datasets in this group. Compare battery swap and charge time against your daily patient throughput: EksoNR and Indego both offer 4 h battery life and 2.5 h charge with swappable batteries; HAL Lower Limb offers 3 h and 2 h charge; Atalante X offers 4 h and 3 h charge; ExoMotus M4 offers 3 h and 2 h charge. For a full category view, see the medical exoskeleton category.
EksoNR and HAL Lower Limb each have a completeness score of 92 in the database, the highest in this group. Both disclose assist torque (40 Nm), weight, speed, battery and certifications; neither discloses peak assist force or price.
No. Indicative price is undisclosed for all five systems. EksoNR, Atalante X and ExoMotus M4 are quoted by the maker or regional distributor; Indego pricing depends on regional reimbursement and configuration; HAL Lower Limb is often offered as a lease or treatment programme.
None of the five lists stair training as supported. EksoNR and Atalante X state stairs are not supported; Indego, HAL Lower Limb and ExoMotus M4 require clinical assessment for stairs. Overground gait training in this dataset means level ground and, for EksoNR and Atalante X, ramps or slopes.
Request a documented peak assist force and peak assist torque figure from Ekso Bionics, Cyberdyne and Wandercraft before you shortlist, and use the ExoSelect inquiry desk to log which vendors respond with numbers versus which defer to a sales call. That single comparison will tell you more about a vendor's procurement transparency than any brochure.
