Empirical practical evaluation instrument for thermoplastic materials for orthoses

Abstract

Introduction: After the advent of low-temperature thermoplastics, their prevalence in the manufacture of orthoses for upper limbs has been identified by several authors. The understanding of their properties by occupational therapists and other professionals working in this field is important in the process of selecting the thermoplastic, which follows a logic to match the material’s characteristics to the desired function for each orthosis. Objectives: Systematize the characteristics of low-temperature thermoplastics and, from that, develop an instrument for carrying out practical empirical tests with the materials, to establish criteria for their handling and evaluation. Method: Exploratory study consisting of the creation of testing procedures and, consequently, the development of a qualitative assessment instrument that values the practical experience of the professional who handles the material and evaluates each requirement. Results: The created instrument includes 14 material characteristics, accompanied by a definition, a procedure with recommendations for the practical testing, and a field for filling in response alternatives. Conclusions: The instrument considers important characteristics to be verified during the evaluation of materials and can direct the professional’s observations and records, aiding in clinical decision-making. This will be important to improve the quality of orthoses and other assistive technology devices made with these thermoplastics. In addition, the systematization of the practical evaluation of thermoplastic materials can assist in the development of health studies and research involving materials for orthoses.
