Preventing Progressivity in Becker Muscular Dystrophy Patient: A Rare Case Report

Introduction: Becker muscular dystrophy (BMD) is a genetic disease caused by mutation of the dystrophin gene due to defects in the Xp21.2 chromosome and inherited by X-linked recessive. BMD is a slowly progressive weakness from proximal muscle. BMD patients are rarer than duchenne muscular dystrophy (DMD). Case Description: An 18-year-old male came with weakness in both legs, mainly at the base of the thigh. The symptoms have been felt for the last three years and progressively for the last two years. He felt a change in walking style and difficulty standing from a sitting position. He denied any family history. Examinations found increased creatine kinase (CK) and electromyography (EMG) showed myopathy in the right femoral nerve. Patient took vitamins daily, done exercise therapy and neuromuscular electrostimulation (NMES) once a week. Conclusion: Diagnosing BMD is not only from history taking and physical examination but also necessary to consider CK levels and myopathy on EMG, even though genetic testing or muscle biopsy could not be done. Until now there is no guideline related to BMD therapy programs, further research is expected to discuss BMD therapy program in detail.
