This non-randomized controlled quasi-experimental study evaluates the effectiveness of an integrated medical-surgical and physiotherapy community-based care model for pregnant women with chronic diseases. Eligible pregnant women aged 18 years or older and enrolled before 20 weeks of gestation are allocated to either an intervention group receiving coordinated multidisciplinary care plus individualized physiotherapy or a control group receiving standard antenatal care. The intervention includes standardized clinical pathways, care coordination, self-management education, community linkages, and physiotherapy exercises tailored to gestational age, chronic disease type, and baseline functional assessment. Outcomes are assessed at baseline, delivery, and 6 weeks postpartum and include maternal complications, neonatal outcomes, quality of life, treatment adherence, patient satisfaction, healthcare utilization, and maternal physical-function indicators.
