Orthoses

Textiles and structural reinforcement

A knitted orthosis differs from a splint with a rigid frame. Stays, inserts and moulded components may supplement a textile body. Their presence, position and materials contribute to the construction. The flexibility of the outer covering therefore does not fully describe the rigidity of the assembly. A strap closure and a tubular sleeve are also different presentations, with their own sizing characteristics. Colour and fabric appearance cannot alone identify the internal support or the distribution of reinforcement.

Joints and movement-control components

Some orthoses contain a hinge or movement-control elements, while others use a non-articulated structure. These features differ from a simple lateral stay. The word hinged does not imply unrestricted adjustment for every purpose. Adjustable components belong to a defined design and intended use. The frame, hinge points, straps and reinforcement therefore provide concrete ways to distinguish the structure and geometry of an orthosis. This keeps equipment information distinct from the decisions made by the professionals responsible for the individual care plan.

Anatomical coverage, side and size

A wrist, thumb or knee orthosis is not simply a different size of the same support. Coverage and contact points differ. Some designs are side-specific, while others are constructed for either side. Sizing may depend on a circumference or length defined for the particular model. Two products labelled medium therefore do not establish the same measurements across every orthosis family. The relevant body area, measurement convention and declared laterality are separate parts of the specification.
