Indego by Parker Hannifin: 12.3 kg, 4 h battery, FDA/CE. A procurement spotlight on what the datasheet reveals and what it hides.

Checked for sourced parameters, internal links and prohibited claims.
The Indego is a strong candidate when you need a lightweight, modular powered exoskeleton for supervised gait training or personal mobility, with documented FDA and CE certification. It is less suitable if your programme requires stair negotiation, published assist torque figures, or a transparent capital price before commitment. This spotlight uses the ExoSelect database to separate what Parker Hannifin publishes from what a buyer must verify directly.
Parker Hannifin lists the Indego as a modular lower-limb exoskeleton built from carbon fibre and aluminium. The modular hip, thigh and shank sizes are a practical advantage for clinics fitting multiple patients, though the datasheet does not state how many discrete sizes exist or the adjustment range per segment. The system offers four degrees of freedom, two control modes (intuitive movement and therapist-controlled gait), and joint position and force sensors. Connectivity includes Bluetooth and session data logging, which supports billing and outcome reporting. The battery is lithium-ion, swappable, and charges in 2.5 hours. Certifications are FDA and CE, with the standard IEC 60601-1 cited. Clinical evidence is described as peer-reviewed gait training studies, but no specific study names or endpoints are given in the database.
The table below uses only specifications present in the ExoSelect database. Where a value is missing, it is marked Unknown or Not disclosed.

Indego stands out for its low weight and high user weight limit. It is the only system in this set with a 113 kg capacity, which may suit a broader patient demographic. However, it lacks the published 40 Nm assist torque of EksoNR and HAL, and it does not offer the 12 degrees of freedom or 80 kg lift support of Atalante X. The trade-off is clear: Indego prioritises portability and modular fitting over maximum assistive force or multi-joint support.
Three parameters are missing or unverified in the database, and each has direct procurement consequences.
Additionally, the datasheet does not specify the number of modular sizes, the adjustment increments, or the maximum user weight for each configuration. These details affect fitting time and patient throughput. The warranty is 12 months, but service level agreements, spare parts availability and training costs are not listed. Lead time is described as "contact regional distributor", which introduces uncertainty for planned deployments.
Do not choose the Indego if your clinical protocol requires stair training or if you need documented assist torque to satisfy internal biomechanical review. The datasheet states that sit-to-stand and level walking are supported, with clinical assessment required for stairs, and it does not publish torque. If your patients regularly exceed 195 cm in height, the Indego will not fit, whereas EksoNR covers up to 193 cm and HAL up to 190 cm, so neither is better for very tall users. If you need a system that provides lift support for sit-to-stand transfers, the Indego is rated not applicable, while Atalante X offers 80 kg. Finally, if you require a fixed capital price before board approval, the undisclosed pricing and regional variability make Indego a harder sell than a system with a published list price, though none in this dataset disclose prices.
Start with patient anthropometry. The Indego covers 155–195 cm and up to 113 kg, which is a wider weight range than the other systems here. If your caseload includes heavier patients, Indego is the only option in this set. Next, consider the therapy model. The two control modes (intuitive movement and therapist-controlled gait) suggest it can be used for both active-assisted and passive training, but the datasheet does not quantify the assistance levels. Ask for a demonstration of the therapist interface and the session data logging export format. Battery swapping is supported, and 2.5-hour charge time means a spare battery can keep a clinic running through a full day. The 12.3 kg weight is light enough for one therapist to transport, but check the carry handle and folding mechanism if you plan to move between rooms. Certifications are FDA and CE, which covers North America and Europe; if you are in Asia-Pacific, confirm local registration, as the regions listed are only North America and Europe.

The database does not disclose price, training costs, service contracts or spare parts pricing. This is a significant gap for total cost of ownership modelling. The 12-month warranty is standard across the systems compared, but what happens after 12 months is unknown. The swappable battery is a plus, but the cost of additional batteries is not listed. Clinical evidence is described as peer-reviewed gait training studies, but without specific citations, you cannot assess the strength of evidence for your patient population. Request the list of publications and the endpoints measured. Also ask about the availability of loaner units during service, as downtime can disrupt therapy schedules.
113 kg, according to the ExoSelect database. This is the highest among the active medical exoskeletons compared here.
The datasheet states sit-to-stand and level walking are supported, with clinical assessment required for stairs. It does not claim stair training as a standard feature.
The regions listed are North America and Europe. Availability in Asia-Pacific is not disclosed; contact Parker Hannifin for regional registration status.
For a direct comparison with the EksoNR, see the EksoNR product page. To evaluate the Indego against other medical exoskeletons, visit the medical exoskeleton category page. To request a documented torque specification or a price band, use the inquiry form and ask for the peak assist torque at the hip and knee, the number of modular sizes, and the post-warranty service contract terms.
