Primary Objective:
To evaluate the impact of a structured, post-operative exercise programme on patient-reported and functional outcomes following DIEP flap breast reconstruction.
Secondary Objectives:
* To examine the effects of the exercise programme on upper and lower limb strength, body composition (BMI, fat and muscle mass, bone density), and functional recovery.
* To evaluate the influence of exercise on post-operative complication rates, length of hospital stay and time to return to daily activities.
* To explore changes in psychological health and body image perception using validated questionnaires.
* To assess adherence, feasibility, and safety of the structured exercise programme within a breast reconstruction population.
* To perform an exploratory health-economic analysis comparing the costs and potential healthcare savings associated with the intervention versus standard care.
