Do current upper limb orthotic classification systems help clinicians choose and design effective orthoses? A scoping...

Orthosis (orthotic) fabrication is an essential part of the treatment plan for many upper extremity conditions.

We aim to comprehensively identify the current body of evidence about the purpose, structure, scope, and application of available orthotic classification systems. Our secondary aim was to know if the current classification systems can be used as a decision guide for clinicians.

A scoping review.

A scoping review of research studies identified through data-based and gray literature was conducted to determine studies that addressed classification systems of the orthosis (orthotic) in the hand and upper limb. Two investigators screened study titles and abstracts and did the data extraction. To do a comprehensive review, all the hand therapy associations were contacted and asked to share their specific orthosis classification system. To answer our second aim, we discussed our findings with the experts in a panel.

Twelve different classification systems were identified, which were developed with different aims. Five classification systems classified orthosis based on their function (n = 5, 50%); one based on therapeutic goals and proposed a decision algorithm. Two of the proposed systems were aimed at helping in decision-making or offering an algorithm for therapists to help them choose the proper orthosis. The expert panel process identified that the current classification systems could not help clinicians select proper orthosis for their patients.

There are different classification systems which were developed with various aims. However, none of those can help clinicians make informed decisions about appropriate orthosis choices for their patients.
