Resumen

Skeletal muscle abnormalities occur in some patients with scleroderma and manifestations can vary from mild to severe. The incidence or prevalence of muscle involvement has been documented in several published series of patients.^{10 Clements P.J., Furst D.E., Campion D.S. , y al. Muscle disease in progressive systemic sclerosis Arthritis Rheum 1978 ; 21 : 62-71 [cross-ref]

The clinical manifestations and laboratory findings for the muscle abnormalities in scleroderma patients have been well characterized by a number of investigators. Many scleroderma patients, however, do not undergo complete evaluations for muscle dysfunction because the symptomatic weakness may be mild or because of concerns over severe skin involvement, which can complicate procedures such as electromyography or muscle biopsy. New noninvasive procedures such as MR imaging, P-31 magnetic resonance spectroscopy, and near infrared spectroscopy provide unique quantitative data that may be useful not only in the characterization of the disease but also in therapeutic decisions and long-term management of these patients.

Although muscle involvement in scleroderma is usually described as mild,^{40 Seibold J.R. Scleroderma Textbook of Rheumatology. Philadelphia: WB Saunders (1993).
