Medical and assistive systems
Exoskeletons and the support they provide during a specific task
Separate powered clinical systems from passive workplace support and read fit, task coverage and outcome claims with their conditions.
An exoskeleton applies support through a structure worn on the body. Its usefulness depends on where that support acts, how the device fits and which movement the person needs to make. A walking-assistance system and a shoulder-support device should not share an undifferentiated performance claim.
Compare the mechanism and the intended setting
Ekso Bionics describes EksoNR as a powered rehabilitation system for supported standing and walking with clinical supervision. Its clinical product range also distinguishes therapy equipment from personal-use arrangements. Each named device needs its own eligibility and operating documentation. [1]
The company's EVO is a different example. Its product page describes passive upper-body support with springs, no batteries and load transfer toward the hips. Changing spring arrangements changes support within the documented configuration. These mechanical features do not by themselves establish a measured reduction in workplace injuries. [2]

| Example | Documented role | Evidence still needed for a claim |
|---|---|---|
| EksoNR | Powered clinical standing and walking assistance | Relevant patient group, treatment comparison and clinical outcome |
| Ekso EVO | Passive support for chest-level and overhead work | Fit and task-specific assessment, including effects beyond the supported posture |
Observe the whole movement sequence
For an illustrative overhead assembly task, the worker reaches for a part, raises a tool, completes the operation, lowers the arms and moves to another position. Support during the raised-arm phase answers only part of the operational question.
A workplace assessment should include the full sequence and ordinary access needs. Record interference with other equipment and the process for putting on and removing the device. Use the responsible specialist's approved assessment rather than extending the load or exposure to test a limit.
A clinical evaluation similarly needs to retain the support arrangement and supervision. Movement accomplished while wearing a device should not be described as unassisted movement without it.
A mechanical change and a health outcome need separate evidence
Imagine a hypothetical laboratory task in which a measured muscle-activity signal falls from an arbitrary normalized value of 100 to 80 during one movement. The relative decrease is 20% for that signal and condition. It is not a 20% reduction in injury risk, pain or time off work.
This calculation uses invented values to explain the claim boundary. A clinical or occupational outcome requires its own measurement, comparison and follow-up. It cannot be calculated directly from an unrelated mechanical or electrical signal.
Ask whether another part of the task becomes harder or whether a different body area carries additional demand. These questions guide the assessment; this article does not claim a particular effect for either named product.
Keep fitting and support work in the evaluation
For an operational record, separate device setup, active use, adjustments, removal and cleaning. A hypothetical 30-minute task with five minutes of preparation and three minutes of removal occupies 38 minutes before other support work. That arithmetic describes time allocation, not a clinical dose or worker-productivity result.
The wearer should be able to report discomfort or interference through the agreed procedure. Device settings and suitability belong with the qualified team and the manufacturer's instructions. A general size range does not replace an individual fit assessment.
A useful comparison ends with a defined task and the evidence for that task. Keep medical rehabilitation, personal mobility and workplace support in distinct records. Their goals and approval conditions differ even when the devices share the exoskeleton name.
