The Effect of Static Ergocycle on Cardiorespiratory Endurance in Early Ambulatory Duchenne Muscular Dystrophy Patient: A Case Report

Abstract

Duchenne muscular dystrophy (DMD) is a debilitating genetic disorder affecting approximately 1 in 3600-6000 live male births, resulting from mutations in the dystrophin gene. This case report describes a 5-year-old boy in the early ambulatory stage of DMD, presenting with characteristic symptoms such as difficulty to stand, muscle weakness, accidental falls, and impaired motor skills.

The patient underwent a multidisciplinary approach involving medical and rehabilitative interventions to improve quality of life and delay disease progression. The rehabilitation program included physical activities, stretching exercises, and environmental optimization.

The spirometry and 6-Minute Walk Test (6MWT) revealed restrictive lung patterns and reduced exercise capacity. The patient's adherence to corticosteroid treatment, ongoing monitoring, and comprehensive rehabilitation strategies are crucial for maintaining optimal muscle function, and enhancing overall QoL. Pulmonary function evaluation and management are also emphasized, given the common association of pulmonary complications with mortality in DMD.
