This pattern of symptoms is consistent with muscle fatigue in SMA, which is different from constant muscle weakness. With SMA, you may start an activity feeling fine but then experience a measurable decline in muscle function over time - like being able to stand initially but then needing to sit after a short period.

This pattern of symptoms is consistent with muscle fatigue in SMA, which is different from constant muscle weakness. With SMA, you may start an activity feeling fine but then experience a measurable decline in muscle function over time - like being able to stand initially but then needing to sit after a short period. SMA can cause both perceived fatigue (feeling exhausted) and muscle fatigue (decreasing muscle power during activity). This means you might feel tired overall and notice your muscles becoming progressively weaker during activities, even if you start out feeling strong. This pattern often shows up during repetitive daily activities. While these symptoms align with SMA characteristics, it's important to have proper medical evaluation to confirm the cause of your symptoms. Your healthcare provider can use specific tools to assess your fatigue patterns and determine appropriate management strategies.
