It is a major source of disability, particularly due to dyspnoea, which affects one in three patients. Around 400,000 patients are registered under long-term conditions (ALD), and 200,000 receive home-based respiratory support. The most severe cases fall under the category of chronic respiratory failure-a term also applicable to other respiratory or neuromuscular diseases.\n\nWalking Exposes Physical Limitations In patients with respiratory failure, walking rapidly induces disabling dyspnoea, as it may represent their maximal effort. This severely limits autonomy and quality of life. To improve exercise tolerance, clinicians rely on pulmonary rehabilitation (exercise reconditioning, bronchodilators, oxygen therapy). When these measures are insufficient, mobility aids such as scooters or electric scooters may help, although they have limitations (cost, bulkiness, muscular deconditioning).\n\nThe Six-Minute Walk Test (6MWT): A Key Tool The 6MWT is a standardised test that assesses walking distance, dyspnoea, heart rate, and oxygenation. It is used to evaluate the severity and prognosis of respiratory failure and to measure response to treatment. It is integrated into prognostic indices and criteria for assessing the effectiveness of rehabilitation. The only non-standardised parameter remains the type of footwear worn.\n\nResearch Hypothesis Some so-called \"active\" sports shoes enhance walking by design-through cushioning, rocker soles, and rigid inserts-which store and return impact energy to assist propulsion. We hypothesise that wearing such shoes could improve walking performance in COPD patients, as reflected by a greater distance on the 6MWT. If confirmed, this simple and low-cost solution could meaningfully improve the daily lives of many patients.",[82,83,84],"Chronic Obstructive Pulmonary Disease (COPD)","Dyspnoea","Exercise Intolerance",[86,87,83,88,89,90,91,92,93,94,95],"COPD","Six-Minute Walk Test","Active Footwear","Gait","Biomechanics","Pulmonary Rehabilitation","Stair Climbing","Oxygen Saturation","Exercise Capacity","Respiratory Disability","NOT_YET_RECRUITING","2026-02-25",{"date":99,"type":100},"2026-03-03","ACTUAL",{"date":102,"type":76},"2026-04-01",{"date":104,"type":76},"2027-04-01",{"name":5,"class":6},1]
