Floor-Lift Series Pulmonary Rehabilitation for COPD: Short- and Long-Term Outcomes in a North African Setting

Plain-language summary

Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and functional disability, with pulmonary rehabilitation (PR) representing one of the most effective non-pharmacological interventions. However, access to conventional PR programs remains extremely limited in many regions, particularly in North Africa, where resources, infrastructure, and patient adherence pose major challenges. The Floor-Lift Series (FLS) program was developed as a culturally adapted, equipment-free, and low-cost PR alternative. It is based on progressive floor-to-stand transitions - movements deeply integrated into daily routines and familiar in the local cultural context - to enhance feasibility and adherence. This prospective quasi-experimental study will evaluate both the short-term and long-term effects of the FLS program in COPD patients with baseline muscle dysfunction limiting their ability to rise from the floor. The short-term phase involves a 9-week intervention combining supervised and home-based training in three progressive stages (initial, intermediate, and consolidation). The long-term phase includes follow-up assessments at 18 months to evaluate sustained adherence and maintenance of clinical and functional improvements. The primary outcome is the completion rate, defined as achieving ≥22 daily floor-lift repetitions during the final intervention phase and maintaining adherence at long-term follow-ups. Secondary outcomes include changes in dyspnea (mMRC), exertional effort (Borg CR10), disease impact (CAT), mobility (Timed Up and Go), flexibility (fingertip-to-floor distance), exercise capacity (6-minute walk test and 1-minute sit-to-stand test), and the composite BODE index. Safety and psychosocial factors influencing adherence will be monitored throughout the study. The trial aims to provide evidence for a scalable, culturally relevant rehabilitation model for COPD management in resource-limited settings.
