Hypotonia refers to decreased muscle tone, resulting in unusual floppiness. It can occur as an isolated condition (benign congenital hypotonia) or as a symptom of progressive disorders like muscular dystrophy or cerebral palsy. Typically identified in infancy, hypotonia affects muscle resistance and can impact motor development. The condition may be present from birth or develop over time. Treatment approaches vary based on the underlying cause and often focus on improving muscle strength and motor skills through targeted therapies.
