The benefit of exercise for breast cancer-treated women is well documented. However, studies of cardiovascular fitness training for women with breast cancer-related arm lymphedema are rare. The purpose of this study was to investigate the effects of intensive pole walking on arm lymphedema in women treated for breast cancer. Thirty-five women with unilateral lymphedema were included and twenty-three completed an eight-week exercise intervention consisting of pole walking 3-5 times per week, for 30-60 min, at 70%-80% of their maximum heart rate, preceded by a two-week control period. Measurements of arm lymphedema (water displacement method), body weight, cardiovascular fitness (sub-maximal bicycle ergometer test) and subjective assessments (disability of the arm, shoulder and hand (DASH) questionnaire; heaviness and tightness using a visual analogue scale (VAS); and well-being) were performed before the control period and before and after the exercise intervention. The results indicated a significant reduction in total arm volume of the lymphedema arm (p = 0.001), in lymphedema absolute volume (p = 0.014) and lymphedema relative volume (p = 0.015). Significant decreases of heart rate (p = 0.004), DASH score (p = 0.053) and rating of tightness in the arm (p = 0.043) were found. Positive and negative influences on well-being were reported. The conclusion of this study is that pole walking is feasible for breast cancer-treated women with arm lymphedema.
Arm lymphedema is a well-known side effect of breast cancer treatment. Studies of the effect of physical exercise on arm lymphedema are very rare. The purpose of this study was to investigate the influence of pole walking on breast cancer-related arm lymphedema when using a compression sleeve. Twenty-six women with unilateral arm lymphedema took part in a clinical study of pole walking on one occasion, 4 kilometers for 1 hour. Measurements were made before, immediately after, and 24 hours later. Results revealed no changes in total arm volume of the swollen arm, measured with water displacement method, or in subjective assessments of heaviness and tightness in the affected arm using visual analogue scale. Immediately after pole walking, a temporary increase in total arm volume of the healthy arm (P=0.037) was found. Twenty-four hours later, no differences were found compared to the measurements before walking. The median for perceived exertion immediately after pole walking, measured with Borg scale, was 11 ("fairly light"). The results suggest that a controlled, short-duration pole-walking program can be performed by patients with arm lymphedema, using a compression sleeve, without deterioration of the arm lymphedema.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
