Long-term Observation in Patients with Duchenne Muscular Dystrophy with Early Introduction of a Standing Program...

Area of Science:

• Neurology
• Orthopedics
• Pulmonology

Background:

• Duchenne muscular dystrophy (DMD) is a progressive genetic disorder impacting muscle strength.
• Scoliosis and pulmonary dysfunction are common complications in DMD patients.
• Early intervention strategies are crucial for managing DMD progression.

Purpose of the Study:

• To investigate the impact of an early-introduced standing program on patients with Duchenne muscular dystrophy.
• To assess the effectiveness of knee-ankle-foot orthoses (KAFO) in managing scoliosis progression in DMD.
• To evaluate the influence of a standing program on ambulation duration and pulmonary function in DMD.

Main Methods:

• Retrospective observational study of 41 DMD outpatients (aged 15-20 years).
• Standing program introduced using KAFO for patients with ankle dorsiflexion < 0°.
• Comparison between patients completing, discontinuing, and not using the standing program.

Main Results:

• The standing program with KAFO was significantly associated with a smaller Cobb angle at age 15.
• Significant correlations observed between ankle dorsiflexion, non-ambulatory period, Cobb angle, and forced vital capacity.
• Patients completing the standing program showed delayed ambulation loss, slower scoliosis progression, and reduced pulmonary dysfunction compared to the non-standing group.

Conclusions:

• Early implementation of a standing program using KAFO may prolong ambulation in DMD patients.
• This intervention shows potential in mitigating scoliosis progression and pulmonary decline in DMD.
• Standing programs represent a valuable therapeutic approach for managing Duchenne muscular dystrophy complications.
