After the first part on traumatic conditions, in this review, the authors aim to discuss the applicability of ultrasound imaging for nontraumatic muscle disorders in the daily clinical/academic practice. While trying to summarize the whole spectrum (e.g., myofascial pain syndrome, inflammatory diseases, neuromuscular disorders), special emphasis will be given to sarcopenia, which is, by far, the most challenging clinical condition in the era of “aging world.” Of note, rehabilitation with regard to the exemplified problems will also be briefed throughout.
