Which of the following is considered a disadvantage of using AMDs?

The correct answer highlights that one significant disadvantage of using Assistive Mobility Devices (AMDs) is the potential for high maintenance costs. Maintaining these devices can involve regular servicing, replacement parts, or adjustments to ensure they function correctly and safely over time. This ongoing financial commitment may pose a burden for some users or their families, especially if they rely heavily on the device for mobility.

While other options discuss potential concerns related to AMDs, they do not universally apply to all devices or may not be as significant as maintenance costs. For instance, some AMDs are designed for outdoor use as well, and their suitability can vary depending on the model and the user's needs. The impact on physical activity levels or transportability might also differ widely based on the type of device and individual circumstances. Thus, the financial aspect of maintenance stands out as a common and often unavoidable disadvantage associated with AMDs.
