Final answer:
Gowers' maneuver is typically seen in Duchenne's muscular dystrophy, a condition marked by progressive muscle weakness where Gowers' sign indicates weakness of the proximal muscles. It is not commonly associated with myasthenia gravis, which involves autoimmune blocking of acetylcholine receptors on muscle cells.
Step-by-step explanation:
Gowers' maneuver or sign is typically seen in neuromuscular disorders, specifically in conditions like Duchenne muscular dystrophy (DMD). When asked which neurologic condition typically displays Gowers' maneuver among the options provided, the correct answer is D. Duchenne's muscular dystrophy. Gowers' sign is a medical sign that indicates weakness of the proximal muscles, namely those of the lower limb. Patients with this condition use their hands and arms to "walk" up their own body from a squatting position due to lack of hip and thigh muscle strength. It is not commonly associated with myasthenia gravis, which is a neuromuscular disorder characterized by the immune system blocking acetylcholine receptors on muscle cells, leading to progressive muscle weakness and fatigue. This autoimmune response results in symptoms like drooping eyelids and general muscle weakness. Other options, such as myasthenia gravis, multiple sclerosis, Huntington's disease, and myotonic dystrophy, do not typically demonstrate the Gowers' sign.
