Abstract: Background: The most common complication following breast cancer intervention surgery is a lack of shoulder function of the affected side, which has been linked to a decrease in quality of life. Presently, few reports are available that examine the benefits of a limited active, rehabilitative shoulder program to assist this population during their recovery period (6-9 months). \n \nHypothesis: Implementing a specific active exercise program (9 weeks) for breast cancer survivors, 6-9 months post-surgery will improve this populations perceived quality of life, perceived shoulder function, improve their observational posture, decrease lymphedema and improve their active shoulder range of motion. \n \nStudy Design and Methods: This study was approved by York Universitys Human Participants Review Sub-Committee and Mount Sinais Toronto Academic Health Sciences Network. The exercise program targeted muscle range of motion, strength, endurance and included the following exercises: static pectoralis stretch, active shoulder lateral raises with internal rotation, bent over row and standing push-ups. The exercise program was progressive (an increase of 5 repetitions per week) and was the same four exercises for each participant within the study. All participants (n=6) were assessed at baseline, four weeks post-baseline and eight weeks post-baseline. Only baseline measurements and final assessment were analyzed for the overall true effect of the exercise intervention. Outcome measures included: Quality of Life questionnaires (EORTC QLQ-C30, QLQ-BR23 and DASH), clinical postural evaluation, measurement of lymphedema (by a cloth measuring tape) and range of motion using a standard manual goniometer. \n \nResults: Upon the completion of the study, participants found a perceived improvement in the social functioning scale, with a mean change from baseline to final assessment: 58.0-77.7 (t=-2.91, p=0.03, SD 11.79), and pain scale, with a mean from baseline to final assessment: 41-22 (t=3.80, p=0.01, SD11.79). Furthermore, participants perceived an improvement in their shoulder function in approximately 20% of the DASH questionnaire items and clinically, the participants shoulder range of motion made a relevant improvement from baseline to final assessment. \n \nConclusion: The implementation of an active and daily exercise program was statistically significant and clinically relevant in the perceived improvement of quality of life, both a perceived and an observational improvement in shoulder function for breast cancer survivors 6-9 months post-surgery.
