"Adult Spinal Muscular Atrophy" is a medical condition that affects the nerves and muscles, leading to muscle weakness, atrophy, and degeneration. However, there are some opposite terms that can be used to describe someone who is free of this debilitating condition. These include "healthy," "able-bodied," and "strong," denoting that the person is physically fit and able to perform daily activities without hindrance. Conversely, the antonyms of Adult Spinal Muscular Atrophy can also be used to describe the absence of symptoms, such as "normal," "vibrant," and "energetic," indicating that the person does not experience weakness, fatigue, or pain associated with this condition.
