Randomized Controlled Trial of Weight Training and Lymphedema in Breast Cancer Survivors

Rehana L. Ahmed, William Thomas, Douglas Yee, Kathryn H. Schmitz

PURPOSE: Lymphedema is a common condition that breast cancer survivors face. Despite a lack of supporting evidence from prospective observational studies, occupational and leisure time physical activity are feared to be possible risk factors for lymphedema onset or exacerbation. We examined effects of supervised upper- and lower-body weight training on the incidence and symptoms of lymphedema in 45 breast cancer survivors who participated in the Weight Training for Breast Cancer Survivors study.

METHODS: Participants were on average 52 years old, 4 to 36 months post-treatment, and had axillary dissection as part of their treatment. Thirteen women had prevalent lymphedema at baseline. The intervention was twice-a-week weight training over a period of 6 months. Lymphedema was monitored at baseline and 6 months by measuring the circumference of each arm, and by self-report of symptoms and clinical diagnosis.

RESULTS: None of the intervention-group participants experienced a change in arm circumferences 2.0 cm after a 6-month exercise intervention. Self-reported incidence of a clinical diagnosis of lymphedema or symptom changes over 6 months did not vary by intervention status (P = .40 and P = .22, respectively).

CONCLUSION: This is the largest randomized controlled trial to examine associations between exercise and lymphedema in breast cancer survivors. The results of this study support the hypotheses that a 6-month intervention of resistance exercise did not increase the risk for or exacerbate symptoms of lymphedema. These results herald the need to start reevaluating common clinical guidelines that breast cancer survivors avoid upper body resistance activity for fear of increasing risk of lymphedema.

Effects of Pilates Exercises on Shoulder Range of Motion, Pain, Mood, and Upper-Extremity Function in Women Living with Breast Cancer: A Pilot Study

Keays, KS, S. R. Harris, J. M. Lucyshyn and D. L. Macintyre

BACKGROUND AND PURPOSE: The purpose of this study was to examine the effects of Pilates exercises on shoulder range of motion (ROM), pain, mood, and upper-extremity (UE) function in women who had been treated for breast cancer. Participants: The participants were 4 women who had undergone axillary dissection and radiation therapy for stage I to IV breast cancer. METHODS: A nonconcurrent, multiple-baseline, single-subject research design was used to examine the effects of Pilates exercises on the 4 outcomes. RESULTS: Visual analyses of the data suggest a modest effect of the Pilates exercise program in improving shoulder abduction and external rotation ROM. Statistically significant improvement in shoulder internal and external rotation in the affected UE was shown for the one participant with pre-existing metastatic disease. The improving baselines seen for pain, mood, and UE function data made it impossible to assess the effects of Pilates exercises on those outcomes. No adverse events were experienced. DISCUSSION AND CONCLUSION: Pilates exercises may be an effective and safe exercise option for women who are recovering from breast cancer treatments; however, further research is needed.

Effect of Exercise on Upper Extremity Pain and Dysfunction in Head and Neck Cancer Survivors: A Randomized Controlled Trial.

McNeely, ML, M. B. Parliament, H. Seikaly, et al.

BACKGROUND: Shoulder pain and disability are well recognized complications associated with surgery for head and neck cancer. This study was designed to examine the effects of progressive resistance exercise training (PRET) on upper extremity pain and dysfunction in postsurgical head and neck cancer survivors. METHODS: Fifty-two head and neck cancer survivors were assigned randomly to PRET (n = 27) or a standardized therapeutic exercise protocol (TP) (n = 25) for 12 weeks. The primary endpoint was change in patient-rated shoulder pain and disability from baseline to postintervention. Secondary endpoints were upper extremity strength and endurance, range of motion, fatigue, and quality of life. RESULTS: Follow-up assessment for the primary outcome was 92%, and adherence to the supervised PRET and TP programs were 95% and 87%, respectively. On the basis of intention-to-treat analyses, PRET was superior to TP for improving shoulder pain and disability (-9.6; 95% confidence interval [95% CI], -16.4 to -4.5; P = .001), upper extremity strength (+10.8 kg; 95% CI, 5.4-16.2 kg; P < .001), and upper extremity endurance (+194 repetitions x kg; 95% CI, 10-378 repetitions x kg; P = .039). Changes in neck dissection impairment, fatigue, and quality of life favored the PRET group but did not reach statistical significance. CONCLUSIONS: The PRET program significantly reduced shoulder pain and disability and improved upper extremity muscular strength and endurance in head and neck cancer survivors who had shoulder dysfunction because of spinal accessory nerve damage. Clinicians should consider the addition of PRET in the rehabilitation of postsurgical head and neck cancer survivors.
