This study evaluated the functionality and wear comfort of five types of ready-made lumbar support braces by conducting in-depth interviews and surveys of eight middle-aged women in their 40s and 50s with a history of lumbar disorders. The number and arrangement of stays, as well as the height and material of the brace, significantly affected comfort and fixation. Lumbar support braces with two or four stays offered exceptional fixation and compression due to the appropriate number and placement of stays in these devices. Brace 3 exhibited excellent body conformity and comfort, although its fixation was relatively limited. The highly rigid brace 5 effectively relieved pain but restricted movement, making it uncomfortable for daily use among those experiencing moderate pain. The participants suggested improvements such as minimizing contact with sensitive areas (e.g., the chest and pelvis), using mesh materials with superior breathability and flexibility, incorporating four or more stays into braces, and employing Velcro fastenings. They also highlighted the need for design considerations based on gender, age, and pain severity, as well as clear usage guidelines for suitable conditions and pain levels for each product.
