Breast cancer is the most common cancer for Canadian women. Of the women who will have a mastectomy each year in Canada, one in five will elect to have breast reconstruction. However, the significant benefits for body-image, self-esteem, sexuality, and quality of life are tempered by post-treatment shoulder dysfunction for many. As a means to decrease shoulder morbidities in breast cancer survivors (BCS), this study will introduce a mobile application (app)-based shoulder rehabilitation program as an option to improve functional outcomes of the shoulder, for those who have had breast reconstruction.
The percentage of Canadian women surviving at least 5 years beyond initial diagnosis is currently approaching 90% and many of these women are choosing to have breast reconstruction following mastectomy. Potential sequelae from both mastectomy and all types of breast reconstruction surgeries can result in various functional limitations. The most common adverse effect from breast cancer surgery is shoulder morbidity, having both short and long-term consequences for survivors, and evidence suggests women who undergo breast reconstruction are at even higher risk of developing shoulder problems. Shoulder/arm pain, reductions in strength, and limitations in range of motion (ROM) are some of the common physical issues plaguing BCS, often for years after the initial treatment. Fibrosis of the direct area of the target tissue is a common finding post radiation therapy, specifically of the anterior chest/ pectoralis and axilla regions in BCS and most noticeable starting six months post-surgically. The researchers' interest in the feasibility of a shoulder rehabilitation mobile app for post-surgical BCS is to improve access to rehabilitation (including education, exercises, and remote support with a physical therapist, PT) for these women, allowing for better functional outcomes which could translate into decreased reliance on medical care, improved quality of life (QoL), and ability to participate in life roles.

Shoulder Range of Motion (ROM)
ROM measurements of both shoulders (flexion, extension, abduction, internal and external rotation) will be taken post-operatively, via the downloaded app on each participant's phone, and by visual examination of the research assistant (registered, licensed PT) during the virtual assessment via Zoom. These ROM measures, taken at the beginning of the intervention (week one), mid-intervention (week four), and end of intervention (week eight) will be used as a guide for exercise progression throughout the intervention. The measurements will also be used in our data analysis to understand changes in shoulder ROM from the beginning of the intervention to the end of intervention.
Time frame: At start of the study, at 4 weeks into the study and again at the end of the study (8 weeks into the study).
Quick Disability of Arm, Shoulder and Hand (Quick DASH)
The Quick DASH is an 11-item questionnaire measuring perceived upper extremity functional ability as well as symptoms on a 5-point scale from 1 (no difficulty) to 5 (unable) (Budtz, 2018). The Quick DASH is quick and easy to administer and to score, and has been used to measure shoulder function in the BCS population in previous studies (Chan et al., 2020; Duymaz et al., 2019; Lang et al., 2020). Data from this questionnaire will be used to better understand changes in upper extremity functional ability and symptoms from the start to end of intervention.
Time frame: At start of the study, at 4 weeks into the study and again at the end of the study (8 weeks into the study).
Visual Analogue Scale (VAS)
The VAS is a tool measuring intensity of symptoms from 0 (no pain) to 10 (worst pain). Each participant will be asked to rate their current shoulder pain on the continuum of this tool and this rating will be used to understand the level of shoulder pain of each participant on the day of assessment. Pain levels from start of intervention, to mid-intervention (at four weeks), to end of intervention (at eight weeks), will be analyzed using continuous ordinal regression or normal-distribution methods (t-test, linear regression) depending on the data collected, and to best understand significance of changes in pain levels from beginning to end of the intervention (Heller et al., 2016). Because of its simplicity and ease of use, it can be administered broadly across a wide variety of populations and can be presented in multiple ways, targeting certain populations of interest (Wewers et al., 1990).
Time frame: At start of the study, at 4 weeks into the study and again at the end of the study (8 weeks into the study).
Fatigue Assessment Scale (FAS)
The FAS is a 10-item questionnaire, that measures fatigue symptoms on a 5-point scale from "Never" (1) to "Always" (5). Although the development and use of most fatigue scales, including the FAS, have been disease specific, most often they have been developed to assess fatigue in people with cancer (Hjollund, 2007). The FAS will be analyzed similarly to the VAS to best understand significance of changes in fatigue levels from beginning to end of intervention.
Time frame: At start of the study, at 4 weeks into the study and again at the end of the study (8 weeks into the study).
Short Form 36 (SF-36)
The SF-36 is a 36-question survey aimed at measuring quality of life (QoL). This tool has been well researched and highly used in all populations, including healthy and disease specific populations (Ware et al., 1992), as well as in research (Ware et al., 1992; Lins et al., 2016). Reliability of the SF-36 is good for several diagnoses, including adult survivors of childhood cancer (Reulen, 2006). As the SF-36 measures both physical and mental health, research suggests its use in combination with other outcome measures when assessing overall QoL (Lins et al., 2016), hence the inclusion of other outcome measures as described above.
Time frame: At start of the study, at 4 weeks into the study and again at the end of the study (8 weeks into the study).
