Muscle biopsies from the descending portion of the trapezius muscle were studied in 9 healthy subjects and in 10 patients with localized chronic myalgia related to static load during repetitive assembly work for 16 (10-31) years, with 10 (4-26) months of sick leave at the time of biopsy. Both categories showed isolated atrophic muscle fibers and occasional abnormal fibers with internally situated nuclei, some variation in fiber diameter, and fiber splitting. Fibers with a "moth-eaten… CONTINUE READING
