The reliability of the thickness measurement of the lumbar multifidus (LM) using real-time ultrasonography (US) was determined in only the superficial fiber of the lumbar multifidus (SM). However, previous studies have not examined the reliability of the deep fiber of the LM (DM). The purpose of this study was to determine the intrarater and the interrater reliability of the thickness measurements of DM using US. Eleven healthy males participated in the study. The thickness of the DM was measured with an US in the prone position. Reliability was examined using intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and the Bland and Altman plot. ICC(3,1) was used to calculate the interarater reliability of the thickness measurement of DM using the values from both the first and second test sessions. Additionally, ICC(3,1) was used to calculate the intrarater reliability of the measurements over two days using the measurements obtained in test session 1 and test session 2. The results of this study were as follows: 1) the ICC(3,1) value for interarater reliability was .94 in the first test session, and .93 in the second test session. 2) the ICC(3,1) values for intrarater reliability of the measurements over two days was .90 in both the first examiner and the second examiner The intrarater reliability and interrater reliability of the DM measurements, obtained via the US protocol used in this research was excellent. Therefore, we conclude that the thickness measurement of the DM obtaioned from the US protocol used in this research would be useful for clinician assessment of the thickness of the DM

The lumbrical muscles contribute to the intrinsic plus position, that is simultaneous metacarpophalangeal (MCP) flexion and interphalangeal (IP) extension. The strength of the lumbrical muscles is necessary for normal hand function. However, there is no objective and efficient method of strength measurement for the lumbrical muscles. In addition, previous studies have not investigated the measurement of the cross-sectional area (CSA) of the lumbrical muscles using ultrasonography (US) and the relationship between lumbrical muscle strength in the intrinsic plus position and the CSA. Therefore, the purpose of this study was to identify the measurement method of the CSA of the lumbrical muscles using US and to examine the relationship between maximal isometric strength and the CSA of lumbrical muscles. Nine healthy males participated in this study. Maximal isometric strength of the second, third, and fourth lumbrical muscles was assessed using a tensiometer in the intrinsic plus position which isolated MCP flexion and IP extension. The CSA of the lumbrical muscles was measured with an US. The US probe was applied on the palmar aspect of the metacarpal head with a transverse view of the hand in resting position. There was no significant difference between maximal isometric strength of the lumbrical muscles, but the fourth lumbrical muscle was stronger than the others. The CSA of the lumbrical muscles was significantly different and the fourth lumbrical muscle was significantly larger than the second lumbrical muscle. There was moderate to good correlation between maximal isometric strength and the CSA of the lumbrical muscles. Therefore, we conclude that maximal isometric strength of the lumbrical muscles was positively correlated to the CSA of the lumbrical muscle in each finger, while the measurement of the CSA of the lumbrical muscles, using US protocol in this study, was useful for measuring the CSA of the lumbrical muscles.

The purpose of this study was to compare EMG activity for pectoralis major myscle during shoulder movement with various abduction angle and rotation position in supine position. Fifteen healthy subjects were recruited for this study. All subjects performed shoulder horizontal adduction holding a 2kg dumbbell in shoulder abduction 40°, 70°, 90°, 130°, 160° with shoulder neutral, internal rotation(IR), and external rotation(ER). Surface EMC activity was recorded from pectoralis major clavicle part and pectoralis major sternum part for 5 seconds and EMG activity was normalized to the value of maximal voluntary isometric contraction (%MVIC). Dependent variable were examined with 3 (Neutral, IR, ER) x 5(40°, 70°, 90°, 130°, 160°) analysis of variance with repeated measures. THe EMG activity of pectoralis major muscle was significantly different between shoulder abduction angles and between shoulder rotation positions(p<.05). The highest value of EMG activity of pectoralis major sternum pars among shoulder abduction angles was in 130° and 90° in that order. According to the rotation degree, shoulder ER showed the highest value and IR showed the lowest value in both muscle parts. these results suggest that shoulder abduction 70°, 90°, 130° will be effective during manual muscle testing(MMT) and strengthening exercise for pectoralis major muscle. It is also supposed that shoulder ER is the efficient posture for strengthening of pectoralis major muscle.

N/A Objectives: 80-90% of the cases of hepatocellular carcinoma(HCC) are associated with cirrhosis. Hepatitis B virus(HBV) is known as a major etiologic factor of HCC and about 10% of Koreans are HBV carriers. And the prevalence of HCC is high in Korea. Early detection of HCC is important for the better treatment especially in the patients with cirrhosis who usually have the decreased functional hepatic reserve. Risk factors for the hepatocellular carcinoma in the korean patients with cirrhosis were evaluated. Methods: Risk factors for hepatocellular carcinogenisis such as age, sex, ascites, alcohol, HBsAg, anti-HCV, AFP, ICG R(15) and risk score were investigated among the 176 patients with cirrhosis and HCC(group I) and 72 patients with cirrhosis(group II) and compared between the two groups. Results: 1) No age difference was noted between group I and group II. 2) Male to female sex ratio were 5.7: 1 and 2.4: 1 for group I and II in each(p<0.01) and the frequency of HCC among cirrhosis was higher in male than female sex(p<0.01). 3) Both HBsAg and anti-HCV positivity were significantly higher in group I than in group II (p<0.01 and p<0.05 respectively). 4) The frequencies of Child-Pugh A, elevated AFP, elevated ICG R(15) and the frequency of super-high risk patient were higher in group I than in group II(p<0.01). 5) The frequency of alcoholic patients was significantly higher in group II than in group I (p<0.05) but no difference was noted between HBsAg positive group I and group II patients. 6) The frequency of abnormal AST with the level of below 100IU was not significantly different between group I and group II. 7) The frequency of the patients with ascites was higher in group II than in group I (p<0.01). Conclusion: Risk factors for hepatocellular carcinogenesis in korean patients with cirrhosis are male, Child-Pugh A, HBsAg positivity, anti-HCV positivity, absence of ascites, higher AFP, lower ICG R15 and higher platelet count.

Guillain-Barre syndrorne occur rarely as complications of chronic active hepatitis. Only one case of serologically documented chronic active hepatitis B has been reported with Guillain-Barre syndrorne, in Korea. Guillain-Barre syndrome is characterized as an acute, symetrically progressive, inflammatory polyneuropathy. There is often a history of an antecedent infection, usually from a non specific disease of the upper respiratory tract. Occassionally, the syndrome follows a specific disease, usually Cytomegalovirus and Ebstein-Barr virus, influenza A, B. We present a case of Guillain-Barre syndrome associated with chronic active hepatitis B and treated with interferon a-Iib. Neurological symptoms and liver function tests were improved after inter- feron therapy with Hbe Ag/Anti-Hbe seroconversion. (Korean J Gastroenterol 1996; 28:451 - 456)
