Physical Therapy for Depression Quality of Life (Pilot Study Protocol)

This project employs a concurrent nested mixed-methods pilot study with quantitative dominance to evaluate a physical therapy intervention program for adults with Major Depressive Disorder (MDD) within a short-stay psychiatric unit. The quantitative component utilizes a quasi-experimental pre-post design, while the qualitative aspect employs a narrative design through focus groups. Intervention Protocol: The physical therapy intervention will be delivered by trained physical therapists in twice-weekly, 45-minute sessions tailored to the participant's length of hospital stay (anticipated 3-6 weeks). Each session will systematically incorporate: Active Joint Mobility: A series of gentle, controlled movements targeting major joints to maintain or improve their range of motion. Progressive Strength Training: Low-to-moderate intensity exercises utilizing the participant's own body weight and progressive resistance elastic bands, focusing on key muscle groups. Balance Enhancement: A structured set of exercises designed to improve stability and reduce the risk of falls, with the difficulty level adapted to each individual's functional capacity. Relaxation Techniques: Progressive muscle relaxation exercises will be implemented at the conclusion of each session to facilitate physical and mental relaxation. Integrated Health Education: Concurrent with the exercise program, participants will receive brief, integrated health education. This component will cover: The physiological and psychological links between physical activity and mental well-being. The specific benefits of the exercises within the program concerning mood, physical function, and overall quality of life. Practical strategies for incorporating and maintaining physical activity as part of their lifestyle post-discharge. Methods for self-monitoring physical activity levels and mood changes to enhance self-efficacy. Information regarding available community resources and physical activity programs that participants can access after leaving the hospital. Qualitative Data Collection Protocol: Separate focus groups will be conducted with: Patients with MDD: These discussions will explore their lived experiences with MDD, their perceptions of the overall management of their condition during hospitalization, and their specific experiences with the physical therapy intervention program, including any perceived barriers and facilitators to participation and benefit. Healthcare Professionals: Focus groups with the multidisciplinary team (including medical, nursing, and other allied health staff) from the short-stay psychiatry unit will focus on their perspectives regarding the integration of physical therapy into the standard care pathway for patients with MDD, their observations of patient engagement and response to the intervention, and any perceived barriers and facilitators to its implementation within the clinical setting. Focus groups will be guided by semi-structured question guides, audio-recorded with informed consent, and transcribed verbatim. Data collection will continue until thematic saturation is achieved. Thematic content analysis will be employed to identify key patterns and insights from the narratives. Data Analysis Approach: The quantitative data, collected at baseline and post-intervention, will be analyzed using appropriate statistical methods for pre-post comparisons in a single group design. Descriptive statistics will summarize the sample characteristics and outcome measures at each time point. Inferential statistics will be used to assess the magnitude and statistical significance of changes in the primary and secondary outcome measures following the intervention. The qualitative data from the focus groups will be analyzed using thematic content analysis. Transcripts will be independently coded by two researchers, with codes grouped into subcategories and subsequently into overarching themes through a process of iterative refinement and consensus. Measures to ensure the trustworthiness of the qualitative data, such as data and investigator triangulation, will be employed. Finally, a mixed-methods approach will be used to integrate the quantitative findings on the program's potential efficacy with the rich contextual data obtained from the qualitative component, providing a more comprehensive understanding of the intervention's impact and feasibility.
