4 Classification and designation
4.1 Classification
4.1.1 By morphological changes
Finger orthoses are classified into dynamic finger orthoses and static finger orthoses according to changes of their positions and shapes of fingers during use.
4.1.2 By functions
Finger orthoses are classified into fixed (protective) finger orthoses, orthopaedic finger orthoses, compensatory finger orthoses, and limited-position (antispasmodic) finger orthoses according to their functions.
4.2 Designation
4.2.1 Composition of designation
The designation of a finger orthosis consists of a part code, a function code, a company abbreviation, a design serial number and an improvement serial number. Its composition form is shown in Figure 1.
4.2.2 Part code
The part code of the orthosis is denoted by FO.
4.2.3 Function code
"Fixed (protective)" is represented by the English letter F, "orthopaedic" by O, "compensatory" by C, and "limited-position (antispasmodic)" by L.
4.2.4 Company abbreviation
The abbreviation of a company is determined by the company itself.
4.2.5 Design serial number
The design serial number is represented by two Arabic numerals.
4.2.6 Improvement serial number
The improvement serial number is represented by an English letter, A, B, C... in turn. The original design has no letters, and the first improvement is marked with A, and so on.
Example 1: FO-O-XXXX-01: AN originally designed orthopaedic finger orthosis with a company abbreviation of XXXX and a design serial number of 01.
Example 2: FO-F-XXXX-02-A: A fixed (protective) finger orthosis improved for the first time, with a company abbreviation of XXXX, and a design serial number of 02.
