Effects of Mediterranean Diet on Recovery Outcomes in Postoperative Physiotherapy Patients

Thesis Abstract

The recovery outcomes of postoperative physiotherapy patients are significantly influenced by nutritional intake, yet the specific impact of dietary patterns, particularly the Mediterranean diet, remains inadequately explored within surgical rehabilitation contexts. This study aims to investigate the effects of adherence to the Mediterranean diet on recovery metrics among postoperative physiotherapy patients, with objectives including assessing nutritional behavior, evaluating physical and functional recovery parameters, and identifying potential mediating factors such as inflammation markers and pain levels. Employing a mixed-methods design, the research integrates quantitative analysis of clinical and biochemical data with qualitative insights into patient experiences. The study population comprises 150 adult postoperative patients undergoing physiotherapy at two tertiary hospitals over a twelve-month period, selected through stratified random sampling to ensure representativeness across age, gender, and surgical procedure types. Data collection instruments include validated dietary assessment questionnaires (Mediterranean Diet Adherence Screener), standardized functional recovery scales (e.g., Functional Independence Measure), biochemical assays measuring inflammatory cytokines (CRP, IL-6), and patient interviews. Quantitative data will be analyzed using descriptive statistics, multiple regression analysis to examine relationships between diet adherence and recovery outcomes, and repeated-measures ANOVA to evaluate changes over time. Thematic analysis will be applied to qualitative data to contextualize patient perspectives on dietary impact on recovery. It is hypothesized that higher adherence to the Mediterranean diet correlates positively with faster functional recovery, reduced inflammation, and lower pain scores. It is also expected that dietary adherence mediates the relationship between nutritional intake and recovery outcomes. The study seeks to fill a critical gap by providing empirical evidence on how specific dietary patterns influence postoperative rehabilitation, and how these effects can be integrated into clinical practice. Expected findings include statistically significant associations between Mediterranean diet adherence and improved physical function, decreased serum inflammatory markers, and enhanced patient-reported outcomes. Such results would substantiate the role of nutrition in optimizing physiotherapy recovery and inform dietary guidelines for postoperative care. The contribution of this research lies in advancing the understanding of diet-recovery dynamics within physiotherapy, emphasizing an integrative approach combining nutritional and rehabilitative strategies. The main conclusion will underscore the importance of adopting the Mediterranean diet as a complementary intervention in postoperative physiotherapy protocols. Recommendations will focus on incorporating dietary counseling into physiotherapy programs, developing tailored nutritional interventions, and training physiotherapists on nutrition-related factors affecting recovery. The study also advocates for longitudinal research to assess long-term impacts of dietary modifications and calls for policy initiatives promoting nutritional education among postoperative patients. Overall, this research promises to expand the evidence base supporting diet-based interventions in functional recovery, fostering holistic models of postoperative rehabilitation grounded in interdisciplinary collaboration.
