Serial static orthoses are remolded periodically as PROM improves. When is this most appropriate?

• A. When immediate full ROM is required.
• B. When there is no expectation of ROM improvement.
• C. When used with dynamic components.
• D. When gradual increases in ROM are expected.

Answer: (D)

Serial static orthoses work by holding the joint at end-range and progressively increasing that end-range as tissues lengthen. The goal is to produce gradual tissue creep and improved ROM, so you remold the device to a new, greater end angle when PROM shows improvement. This approach is best when you expect steady gains in ROM over time—such as after stiffness from injury or surgery, where the tissues can lengthen with consistent, static stretching. If ROM is needed immediately at full range, or if little to no improvement is anticipated, serial static would not be the most appropriate choice.
