title: Quantitative measure of muscle strength and size in chronic alcoholism: an early indication of tissue damage.
abstract: We measured quadriceps strength and thickness in 101 male alcoholic patients and in 58 controls in order to investigate the force-size relationships of skeletal muscle in an alcoholic population. The relationship of these parameters with the duration of alcoholism, nutritional status and biochemical and haematological markers of heavy chronic alcohol use was investigated. Alcohol consumption of more than 42 standard drinks (420 g alcohol) per week for at least 5 years is associated with muscle weakness and wasting. There was no evidence of under-nutrition in these alcoholic subjects and muscle wasting occurred independently of peripheral neuropathy, a history of muscle pain, abnormalities of liver enzymes and elevation of mean red cell corpuscular volume. Quantitation of muscle size and strength in heavy drinkers may provide a useful early indicator of health impairment in alcoholics.
