Limb-girdle muscular dystrophy is a group of rare inherited conditions that cause progressive weakness and wasting of the muscles around the shoulders, upper arms, thighs, and hips. It usually starts in childhood, adolescence, or early adulthood and slowly worsens over time. It is caused by genetic changes that affect proteins needed for muscle structure and function. Common symptoms include difficulty walking, climbing stairs, and lifting objects, with gradually worsening muscle weakness. There is no cure, but physiotherapy and supportive care can help manage symptoms and maintain mobility.

A CPK (creatine phosphokinase) level of 968 is moderately elevated and indicates that there is ongoing muscle fibre damage, which is expected in limb-girdle muscular dystrophy (a condition that causes progressive muscle weakness and wasting around the shoulders and hips). This level reflects muscle breakdown rather than a specific stage of severity. It does not directly indicate how strong or weak your muscles are or how quickly the condition is progressing. Your doctor will interpret this result along with your symptoms, muscle strength, and changes in CPK levels over time.
