A Study and Development of an Orthosis for Patients with Knee Osteoarthritis

Abstract

This study comprised the investigation of knee osteoarthritis pathology and orthotic application problems among knee osteoarthritis patients and the development of knee osteoarthritis orthotic. The study applied mixed methodology including qualitative and quantitative method. Primary and secondary causes of knee osteoarthritis were investigated. Quality Function Deployment (QFD) was applied in the analysis of customer needs. The research population. Medical personnel and Rehabilitation 3 agencies. The research samples were 20 participants comprised of osteoarthritis experts and patients. Product planning matrix in House of Quality (HOQ) matrix was applied in finding relationships between the customer needs and the technical specifications. Part characteristics for the design and development of knee osteoarthritis were analyzed by applying the product technical specifications for design deployment in House of Quality (HOQ). The findings indicated five part characteristics with significance scores higher than 5% the then create a draft by the Terms subassembly (Sketch Design) began developing the draft to select products, together with physical exercise equipment for patients with osteoarthritis. And process for making effective use. Found to have an appropriate level of work is in motion, sleeping, sitting, standing, with the angle at 0-100.
