What are the common symptoms of proximal muscle weakness and how is it typically diagnosed?

Common symptoms of proximal muscle weakness include difficulty standing up from a seated position, climbing stairs, and lifting objects. It can also lead to a waddling gait and frequent falls.

Proximal muscle weakness is typically diagnosed through a combination of physical examination, medical history review, blood tests to check for muscle enzyme levels, electromyography (EMG) to assess muscle function, and imaging studies such as MRI or CT scans to evaluate muscle and nerve health.
