    Abstract:
    To study motor function quantitatively in alcoholic liver cirrhosis muscle strength, liver function, peripheral nerve function, and nutrition were assessed in 24 patients. Isokinetic strength of flexion and extension at elbow, wrist, hip, knee, and ankle and of shoulder abduction and adduction was evaluated and compared with findings in 24 matched healthy subjects. Degree of liver disease was assessed with the Child-Pugh score and the galactose elimination capacity (GEC). Nutritional status was evaluated with an estimation of lean body mass (LBM) from 24-hour urinary creatinine excretions. Peripheral nerve function was evaluated with neurological symptom and disability scores, nerve conduction studies, and quantitative sensory tests summed to obtain a neuropathy rank-sum score (NRSS) for each patient. Combined muscle strength at hip, knee, ankle, shoulder, elbow, and wrist were weakened with 34% (P < .005), 35% (P < .001), 35% (P < .01), 34% (P < .01), 29% (P < .01), and 29% (P < .02), respectively. The median Child-Pugh score was 7 (range, 5-12), and the median duration of alcohol abstinence was 90 days (range, 5-960 days). After multiple linear regression analysis including LBM, Child-Pugh score, GEC, duration of alcohol abstinence, and NRSS, only LBM was correlated to the strength at the knee (r=.79; P < .0001) and at the ankle (r=.63; P < .01). It is concluded that muscle strength is weakened substantially in alcoholic patients with liver cirrhosis and that weakness is related to the severity of malnutrition but not to the severity of liver disease, duration of alcohol abstinence, or neuropathy.
