10 Signs of Muscular Dystrophy: Recognizing Muscle Weakness Early
Muscle weakness is often the first noticeable symptom of muscular dystrophy. It can manifest in various ways, affecting different muscle groups. Early signs may include difficulty standing up from a seated position, frequent falls, or trouble climbing stairs. Over time, these symptoms may progress, leading to more pronounced challenges in movement and coordination.
Children with muscular dystrophy might exhibit delayed motor milestones, such as walking later than peers. Adults may notice gradual weakening in their arms, legs, or back.
Common Signs of Muscle Weakness
1. Difficulty Rising from the Floor: Individuals may struggle to stand up without using their hands for support, a phenomenon known as Gowers’ sign.
2. Frequent Tripping or Falling: Weakness in the leg muscles can lead to instability and an increased likelihood of falls.
3. Toe Walking: Some children walk on their toes due to tight heel cords, a possible early sign of muscle degeneration.
4. Enlarged Calves: Pseudohypertrophy, where calf muscles appear larger due to fat and connective tissue replacing muscle, is a common indicator.
5. Muscle Pain and Stiffness: Discomfort or stiffness in muscles, especially after physical activity, may signal underlying issues.
6. Fatigue: Excessive tiredness, even after minimal exertion, can be a sign of muscle weakness.
7. Delayed Motor Skills: Children may take longer to reach milestones like sitting, crawling, or walking.
8. Difficulty Running or Jumping: Weakness in the legs can make activities like running or jumping challenging.
9. Poor Posture: Weak back muscles may lead to an exaggerated curvature of the spine.
10. Breathing Difficulties: In advanced stages, weakened respiratory muscles can cause shortness of breath.

When to Seek Help
If multiple signs are observed, consulting a healthcare professional is advisable. Early diagnosis can lead to better management of symptoms. Physical therapy, assistive devices, and lifestyle adjustments may help maintain mobility and independence.
