Which of the following is a clinical manifestation of hypotonicity in Cohen syndrome?

Weak muscle tone is a clinical manifestation of hypotonicity in Cohen syndrome. Hypotonicity, or decreased muscle tone, leads to a lack of resistance to passive movement of the limbs. In individuals with Cohen syndrome, this hypotonicity contributes to difficulties in motor control and coordination.

In the context of Cohen syndrome, decreased muscle tone can affect various aspects of physical development and functioning, including motor skills and posture. Recognizing this manifestation is essential for forming management strategies that may include physical therapy and supportive care to improve muscle strength and overall function.

Other conditions related to hyperactivity or exaggerated reflexes, increased sensitivity, or changes in limb proportions do not align with the characteristics of hypotonicity, making them less relevant in the context of Cohen syndrome.
