- To diagnose muscle diseases, such as muscular dystrophy, myositis, and polymyositis.

- To evaluate muscle weakness and fatigue, especially if the cause is unknown.

- To monitor the progression of muscle diseases and assess the effectiveness of treatment.

- To identify any abnormalities in the muscle tissue, such as inflammation, infection, or tumors.

- To study muscle structure and function in healthy individuals and athletes.

- To obtain muscle tissue for research purposes, such as studying the effects of aging, exercise, and nutrition on muscle health.
