This study explores the effectiveness of community-based exercise programs for individuals with spinal cord injury (SCI) following hospital discharge. Given the rising incidence of SCI, particularly in South Korea, and the associated long-term disabilities, the necessity for comprehensive post-discharge rehabilitation is paramount. The study focuses on a pilot randomized multicenter double-blind controlled trial, targeting SCI patients who have completed inpatient rehabilitation and are living in the community. The primary aim is to evaluate the impact of structured exercise programs on physical fitness, functional capacity, and overall recovery. The research introduces the SpinalFit program, a community-based intervention designed to enhance muscle strength, cardiopulmonary endurance, and mobility through a combination of aerobic and resistance training. This program addresses the critical need for safe and effective rehabilitation options outside the hospital setting, utilizing circuit training with resistance bands and body-weight exercises tailored to each participant's capacity. The study also investigates barriers to physical activity in the community for SCI patients and the potential role of community exercise centers in bridging this gap. Preliminary findings from this pilot trial are expected to provide valuable insights into optimizing exercise regimens for SCI patients, informing future large-scale studies and contributing to improved post-discharge rehabilitation strategies.
