Abstract: | Treatment for breast cancer patients includes surgical removal of the tumor followed by chemotherapy. Chemotherapy frequently results in difficult to manage symptoms that threaten compliance with the therapy. Symptoms include fatigue, declines in functional ability, muscle wasting, and a decreased quality of life. Preparing the body to tolerate a stressful event such as chemotherapy has been termed "prehabilitation". This case study determined the efficacy of introducing aerobic training 1 week prior to and continuing through 8 weeks of chemotherapy on fatigue and functional ability in a 42-year-old newly diagnosed breast cancer patient. The patient participated in a supervised and home-based walking program. Fatigue during daily activities and functional ability (12-minute walk, ascending and descending stairs, sit to stand, getting to and rising from the floor, 30-second bicep curl) were measured before and after exercise training. Results indicate that 5 of 7 functional measures demonstrated improvement, ranging from 23.4- 54.5%. In addition, fatigue while performing activities of daily living, as well as following the performance of the functional tasks, was reduced. The findings of this case study indicate that fatigue can be decreased and functional ability can be improved as a result of aerobic training initiated 1 week before and continued throughout chemotherapy. This case study presents a novel approach to introducing exercise prior to and continued during 8 weeks of chemotherapy in a way that may reduce the cumulative effects of this stressor. |
