Feasibility of Breathwork Intervention With Older Adults After Knee Surgery

Postoperative complications after surgical procedures, including following total knee arthroplasty (TKA), have a negative impact on the health and well-being of surgical patients. Older adults (≥65 years) are particularly vulnerable to postoperative complications and their associated morbidities due to the biological aging process. Older adults comprise nearly half of surgical patients worldwide, and this number is expected to increase in the next 10-20 years as the aging population continues to grow. TKA is the most common procedure undergone by older adults, and the rate of TKA procedures is also expected to rise. Despite perioperative guidelines and protocols to prevent postoperative complications, the prevalence of postoperative complications following TKA is approximately 12%. Given these statistics, millions of older adults undergoing TKA may be at risk for postoperative complications and their associated morbidities in the coming decades. Therefore, additional interventions are needed to combat postoperative complications in this population. The body's natural response to surgery, also known as the surgical stress response (SSR), contributes to postoperative complications through complex mechanisms involving the autonomic nervous system (ANS). Increased sympathetic nervous system (SNS) activity, or the body's fight-or-flight response, causes dysregulation in feedback systems that regulate the stress response, potentially leading to poorer outcomes. Interventions, such as breathwork, that induce the parasympathetic nervous system (PNS), or the body's rest-and-digest response, have been shown to balance the ANS, regulate stress biology, and improve outcomes. This study will examine the feasibility of adding a breathwork intervention (Box Breathing), compared to an attention control, to standard perioperative care for older adults undergoing TKA. This study will also examine the proof of concept that Box Breathing, compared to an attention control, may help regulate the SSR by assessing an objective measure of stress-related biology, diurnal cortisol rhythm, and gathering self-report information on pain, anxiety, depression, and quality of recovery following TKA.

Advancing Family Wellbeing Through a Massive Open Online Intervention: The LightBEAM Program

Early childhood is a critical period for developmental outcomes, and the parent-child relationship plays a vital role in shaping cognitive and social development. However, elevated parental distress (e.g., depression, anxiety, anger) can disrupt healthy relationships, increasing the risk of negative child outcomes such as difficult temperaments, altered cognitive development, and socio-emotional challenges. Despite the well-documented effects of untreated parental distress, Canadian families face significant barriers to accessing timely and effective mental health support. To address this gap, our team developed BEAM, an app-based program that provides parenting and mental health resources. BEAM includes expert-led videos, online forums, progress monitoring, and peer-coaching sessions. Clinical trials to date evaluating BEAM have shown promising results, demonstrating reductions in parent depression, anxiety, and harsh parenting practices. Building on BEAM's success, we have developed the LightBEAM program, which aims to expand these supports into a scalable, accessible, massive online open intervention (MOOI) to reach a larger number of families across Canada, particularly in underserved areas or those on waitlists for individualized services. LightBEAM has the potential to support parental mental health, fostering healthier child and family development while addressing barriers to traditional mental health care. This trial involves a pre-post randomized trial design with primary aims of (1) assessing feasibility and acceptability metrics of LightBEAM including recruitment/retention, sustainability, satisfaction, and unmet needs, (2) examining the efficacy of LightBEAM versus waitlist control at improving family and mental health outcomes, and (3) determine for whom LightBEAM is more or less effective at engaging with and addressing mental health needs. This trial will evaluate the feasibility and effectiveness of LightBEAM with a sample of up to 300 parent participants with a child aged 18-107 months. Co-parents of parent participants are permitted to participate in the study as well but are not included in this sample of 300 parent participants. Study participants will complete 12 weeks of psychoeducation modules in the BEAM app. The LightBEAM program will consist of four different components; weekly parenting and mental health videos, weekly progress tracking, a group forum, and exercises designed to reinforce skills learned through the video content. Assessments of parent and child symptoms will occur at pre-test before LightBEAM begins (T1), immediately after the last week of the LightBEAM intervention (post-test, T2), and 6-month follow-up (T3). The LightBEAM program offers a promising solution to addressing elevated parental mental health symptoms, parenting stress, and related metrics of child well-being. By adapting BEAM, an evidence-based parenting and mental health app, into LightBEAM, a large-scale online intervention, the present trial aims to provide accessible mental health support for Canadian families. LightBEAM could reach families in remote areas with limited services, offer interim support during waitlists, or function as a self-referral program.
