近年來台灣女性的乳癌發生率逐漸增加，隨著醫療技術的進步，病人的存活率因而大大提高。如何增進乳癌患者術後的生活品質成了亟須重視的新課題。傳統上，為避免術後淋巴水腫的發生或是惡化，對於患側上肢的提重有諸多限制，但長久下來，隨著肌力顯著下降，造成病人生活上的功能障礙及諸多不便。本文的個案是一位51歲的女性，在2008年11月作7乳癌切除手術，在2009年8月開始接受物理治療。我們使用個案處理模式，檢查發現其上肢肌力有普遍性的不足，而上肢淋巴水腫已達穩定的階段。使用針對乳癌患者訂定的「全面國際功能、障礙和健康分類核心組合」來做分析，分析本個案在「活動和參與」所面臨的主要問題為「拿物品」及「做家事」，而其主要限制因素為肌力的不足。近年來，逐漸有文獻研究報告指出，在監控以及安全保護之下，給予緩慢漸進式的重量訓練，不僅不會增加肢體水腫，可以減輕淋巴水腫的症狀，也可以增加肌力，提高乳癌患者生活品質。因此，在文獻對乳癌患者重量訓練的正向證據支持之下，我們將重量訓練應用於此個案，幫助其增加肌力，減少生活上主要功能障礙。

The incidence of breast cancer and the survival rate of breast cancer patients are both increasing in recent years. The issue of how to improve function and quality of life of these patients is becoming important. Traditionally, in order to prevent the occurrence of lymphedema of the upper extremity, carrying heavy objects and strengthening exercise are prohibited. Patients' muscle strength may deteriorate and resulted in functional impairment. Our report case is a 51-year-old female of breast cancer. From the "Comprehensive ICF Core Set for Breast Cancer", we identified her major limited "Activity & Participation" being "Lifting and carrying objects" and "Doing Housework". With further analysis of her "body structure and function", "environment" and "personal factor", the major limiting factors of her "Lifting and carrying objects" and "Doing Housework" are insufficient of muscle strength. Recently, several studies have shown that under close monitoring, slowly progressive weight training had no significant effect on limb swelling and could reduce lymphedema symptoms, increase muscle strength, and improve quality of life. Based on the evidences from the literature revealing benefits of weight training to breast cancer survivors, we have applied weight training program to our patient to improve her muscle strength and diminish her functional impairment.
