Which factor is crucial for ensuring the longevity of an orthotic device?

Regular cleaning and maintenance are essential for ensuring the longevity of an orthotic device. This practice helps prevent the buildup of dirt, sweat, and bacteria, which can deteriorate the materials over time and lead to premature wear and tear. Moreover, regular inspections during maintenance can identify any signs of damage or wear, allowing for timely repairs that can extend the life of the device. Proper care ensures that the orthotic continues to function effectively, providing consistent support and protection to the user.

While other factors might seem relevant, they do not contribute as significantly to the longevity of the device. Keeping the device in the dark does not necessarily protect it from environmental damage, and using it only during therapy sessions may not correlate with maintenance or care. Frequent design changes can also disrupt the user's adaptation to the device and may not promote longevity but could instead lead to inconsistencies or discomfort. Thus, focusing on regular cleaning and maintenance is the most critical factor for the longevity of an orthotic device.
