What are the risks and considerations for using an exoskeleton?

While a number of benefits are associated with exoskeleton use, there are also factors to consider prior to using the device in therapy or for the long term.

Robotic exoskeletons are generally safe when used with discretion. However, there are some risks associated with its use. Mild adverse effects that have been reported in research include: skin redness, small abrasions (i.e., scrapes), mild joint swelling, and mild bruising. Additionally, like other simple orthotics and braces, falls and fractures have been identified as a risk. It is suggested (weak evidence) that family and friends of exoskeleton users should be trained to deal with emergency situations, such as falls or the exoskeleton shutting off unexpectedly.

While exoskeleton home use may seem promising, there are some limitations. These include:

• Slow walking speeds, which may not be ideal for everyday activities.
• High costs to purchase the device.
• Lack of availability of community-based exoskeletons.
• Limited capacity or poor efficiency in moving on uneven surfaces (e.g., hills, steps) or complex movements (turning, side-stepping, backwards walking).
• Being prone to water damage (they are not waterproof).
