What is the common symptom for muscular dystrophy?

Muscular dystrophy is primarily characterized by progressive muscle weakness due to the degeneration of muscle fibers. This condition affects the ability of muscles to function properly, leading to a noticeable decline in strength over time. Unlike blindness, growth retardation, or heart palpitations, which are symptoms associated with other medical conditions, muscle weakness is the hallmark indicator of muscular dystrophy. The weakening of muscles can affect mobility, posture, and overall physical function, making it a key symptom that helps in diagnosing the disorder.
