Digital and Interactive Health Interventions Minimize the Physical and Psychological Impact of Breast Cancer, Increasing Women’s Quality of Life: A Systematic Review and Meta-Analysis

SIMPLE SUMMARY: The development of digital and virtual devices for therapeutic purposes has been widely studied in recent years. There is a growing scientific interest in analyzing the effects of digital and interactive health interventions (DIHIs) in the management of different neurological and musculoskeletal pathologies, as well as breast cancer (BC). DIHIs include the use of a wide variety of virtual reality devices, as well as smartphone apps and games, to reduce the impact of BC signs and symptoms on women. In the present review, we assessed the effect of DIHIs, in comparison to conventional interventions or usual care, on improving the motor control and function of the upper extremities affected by lymphedema after BC surgery, including pain, anxiety, depression, and different dimensions of quality of life. In addition, we investigated which type of DIHI was more useful for women with BC: virtual reality devices or smartphone apps. ABSTRACT: Digital and interactive health interventions (DIHIs), such as virtual-reality-based therapy (VRBT) and smartphone-app-based therapy (SABT), may be useful for reducing the impact of the signs and symptoms of breast cancer (BC) in women. The aim of this meta-analysis was to explore the effect of DIHIs on improving pain, anxiety, depression, quality of life (QoL), and upper extremity (UE) disability-related lymphedema in women with BC. Methods: We searched PubMed Medline, Web of Science, Scopus, CINAHL, Physiotherapy Evidence Database, and SciELO for the period ending February 2022. We included studies that assessed the effect of DIHIs on UE motor disability, pain, anxiety, depression, and QoL in women with BC. The effect size was calculated using Cohen’s standardized mean difference (SMD) and its 95% confidence interval (95% CI). Results: Twenty studies providing data from 1613 women with BC were included. With respect to UE disability, DIHIs increased flexion (SMD, 1.92; 95%CI: −1.16, 2.68), abduction (SMD, 1.66; 95%CI: 0.91, 2.42), external rotation shoulder range of motion (SMD, 1.1; 95%CI: 0.36, 1.85), UE function (SMD, −0.72; 95%CI: −1.31, −0.13), and handgrip strength (SMD, 0.4; 95%CI: 0.21, 0.59). DIHIs reduced pain (SMD, −0.8; 95%CI: −1.31, −0.26), anxiety (SMD, −1.02; 95%CI: −1.71, −0.34), and depression (SMD, −1.57; 95%CI: −3.1, −0.08). Finally, DIHIs increased overall health (SMD, 0.6; 95%CI: 0.31, 0.89). Conclusions: Right at the end of therapy, DIHIs are effective at improving UE function, pain, anxiety, depression, and QoL in women with BC. VRBT has a greater effect than SABT for the assessed outcomes.
