Abstract

The mastectomy bra (M-bra) serves as an essential rehabilitative product for individuals who have undergone breast cancer surgery. This study aimed to develop an ergonomic design method for M-bras that addresses both the physiological and psychological needs of post-mastectomy breast cancer patients. Over 270 M-bras with diverse design options were collected from online markets, and more than 100 post-mastectomy patients participated in an online survey to rank their preferences regarding eight M-bra components and 19 design options. An orthogonal experimental design was applied to reduce the vast array of design combinations to 20 M-bra test samples. The Pleasure-Arousal-Dominance (PAD) emotion model and the Self-Assessment Manikin (SAM) scale were then used to collect PAD scores from 40 patients evaluating these test samples. Extreme difference analysis was conducted to evaluate the significance of the M-bra components and identify combinations that generated the highest and lowest PAD levels. Based on the PAD scores, 11 samples were categorized as "delighted" or "relaxed" M-bras due to their positive emotional polarity. Linear regression analysis showed strong correlations between the design options and PAD scores, with R² values of 0.962 for P, 0.819 for A, and 0.949 for D. A backpropagation neural network was developed to predict PAD values for various M-bra design options, achieving prediction errors of 8.06% for P, 6.15% for A, and 13.29% for D, demonstrating satisfactory performance given the subjective nature of the evaluations.

基于情绪测量的乳房切除胸罩人体工学设计

乳房切除术胸罩（M-bra）是乳腺癌术后患者必不可少的康复产品。本研究旨在开发一种符合人体工程学的胸罩设计方法，以满足乳腺癌切除术后患者的生理和心理需求。研究人员从网上市场收集了 270 多种不同设计方案的 M 型胸罩，并对 100 多名乳腺癌术后患者进行了在线调查，以了解他们对 8 种 M 型胸罩组件和 19 种设计方案的偏好程度。采用正交实验设计将大量设计组合减少到 20 个 M-bra 测试样本。然后使用愉悦-烦恼-主导（PAD）情绪模型和自评量表（SAM）收集了 40 名患者对这些测试样本的 PAD 评分。通过极差分析来评估 M-bra 成分的重要性，并确定产生最高和最低 PAD 水平的组合。根据 PAD 分数，11 个样本因其积极的情绪极性而被归类为 "愉悦 "或 "放松 "M-bra。线性回归分析表明，设计方案与 PAD 分数之间具有很强的相关性，P 的 R2 值为 0.962，A 为 0.819，D 为 0.949。我们开发了一个反向传播神经网络来预测各种 M-bra 设计方案的 PAD 值，P 的预测误差为 8.06%，A 的预测误差为 6.15%，D 的预测误差为 13.29%，考虑到评价的主观性，其表现令人满意。
