Patient's question:
Your friend's child has been diagnosed with pseudohypertrophic muscular dystrophy. At first, the posture for lifting the eyes was correct, and around the age of one, they had already started learning to walk, but they always walked unsteadily. Teaching them to walk was also unstable, and climbing even one step of the stairs was very tiring, taking a long time to do so. Hello, what is the cause of pseudohypertrophic progressive muscular dystrophy?Doctor's answer:
The pseudohypertrophic form is inherited in an X-linked recessive manner, affecting males while females are carriers. It typically manifests in early childhood, characterized by delayed walking age, slow gait, and a tendency to fall, with difficulty getting back up after a fall. Most cases involve calf muscle hypertrophy, with relatively strong muscle strength in the initial stages. The gluteus medius muscle becomes fatigued, causing the pelvis to sway up and down; the Achilles tendon contracts, preventing the heel from touching the ground; the psoas muscle fatigues, leading to an anterior abdominal protrusion, a tilted head backward, and a waddling gait.
