Symptom 7: Muscle Weakness – Losing Strength
Muscle weakness, medically referred to as hypotonia, is another symptom that people with spinocerebellar ataxia might experience. This symptom arises from the cerebellum’s degeneration, leading to diminished muscle control and reduced strength.
In the early stages of SCA, the muscle weakness might be subtle and might not even affect day-to-day activities. Individuals might notice a slight reduction in their grip strength or find it slightly harder to open jars or carry heavy objects. However, these changes might be so subtle that they’re easily dismissed or attributed to natural aging.
As the condition progresses, however, the muscle weakness becomes more pronounced. It might become harder to climb stairs, stand up from a sitting position, or perform tasks that require a firm grip. The muscle weakness can also lead to reduced endurance, making individuals tire more quickly during physical activities.
Furthermore, the muscle weakness isn’t confined to the limbs. Individuals with SCA might also experience weakness in their facial muscles, leading to a lack of facial expressiveness. They might find it harder to smile, frown, or show surprise, which can impact their ability to communicate nonverbally.
Despite the challenges that muscle weakness poses, physical therapy can be beneficial in managing this symptom. Regular, guided exercise can help maintain muscle strength and function, improve endurance, and enhance overall physical wellbeing. However, any noticeable decline in muscle strength should be discussed with a healthcare professional to determine its cause and devise an appropriate management plan. (7)
