What is a common sign of skin breakdown from an ill-fitting orthosis?

Localized redness is a common sign of skin breakdown from an ill-fitting orthosis. This occurs because improper fitting can lead to increased pressure and friction in specific areas of the skin. When skin is subjected to mechanical stress, it can become irritated, leading to inflammation and visible redness. This redness indicates that the skin is reacting to the pressure, which may eventually progress to more severe conditions such as blistering or ulceration if not addressed promptly.

In contrast, while increased skin elasticity, persistent itching, and excessive moisture can occur in various dermatological conditions, they are not specific indicators of skin breakdown related to orthotic use. Increased skin elasticity generally relates to skin condition rather than pressure stress. Persistent itching may suggest skin irritation or an allergic reaction but is not a definitive sign of breakdown. Excessive moisture, while it can affect skin integrity, does not directly indicate that an orthosis is ill-fitting or causing localized injury.
