As the static balancing ability of the body is physiologically so complicated, that it is not easy to appraise it objectively and quantitatively. The aim of this study is to asses the motion of the gravity center of the body, using the body-balance analyzer (MGC-O1A, TOSHIBA), and to evaluate the validity of its use in the physical testing system.
The trace of the motion of the gravity center of 30 second duration, while the subject standing quietly on the sense-table with his eyes closed and his toes 60 degree opened, was drawn on the chart sheet and its length (L) was calculated electronically.
Preliminarily, 14 healthy men and women, whose ages ranged from 21 to 48 years old, were subjected to the test six times every day for ten consecutive days. The L values of 60 time measurements of each subject showed a slightly eccentric distribution with the coefficient variation of 20% on the average, but the coefficient variations of logarithmic value of L were small and they were between 2.4 and 6.0%. There was no significant difference between the L in the morning and that in the afternoon. Well-trained subjects seemed to show the smaller L values than the not-trained, but the latter some-times had little values, which might perhaps tell the existance of some predispositional ability for body balancing. Half of the subjects showed a“training effect”; L became smaller as the experimental day went on.
The L values of 2212 male and female subjects, age of those ranging from 19 to 83 years old, who performed the general physical testing, were then analyzed. The distribution of L was that of a “logarithmic normal”and it's geometric mean value was 210.8cm per 30 seconds, where the range of ± 1 S.D. was 149.0-298.3. It seemed that L increased with aging, only with a very low correlation coefficient (r : 0.14) . And there was no significant difference in L values between male and female. Although the multivariate analyses, in which L was set as the object variable, was performed, the correlation between L and the other physical abilities (muscular strength, power, agility, flexibility. and VO₂max) was very low (r : lower than 0.12) .

Purpose: Aluminum potassium sulfate and tannic acid (ALTA; Zion, Mitsubishi Pharma Corp.) is an effective sclerosing agent for internal hemorrhoids. ALTA therapy with a rectal mucopexy (AM) is a new approach for treating hemorrhoidal prolapse. This study compared the early postoperative outcomes of AM surgery with Doppler-guided transanal hemorrhoidal dearterialization and mucopexy (DM) in patients with third-degree hemorrhoids. Methods: AM surgery was performed on 32 patients with grade III hemorrhoids and was compared with a cohort of 22 patients who underwent DM surgery in a previous randomized controlled trial. Results: The pain scores during defecation were significantly lower in the AM patients beginning 4 days after surgery. The total use of analgesics 2 weeks postoperatively was significantly lower in the AM patients than in the DM patients (3.5 tablets [range 1.6–5.5] vs. 7.6 tablets [range 3.3–11.9], P=0.04). The length of operation, blood loss, and incidence of postoperative complications were significantly lower in the AM patients than in the DM patients. During 12 months follow-up, recurrence of prolapse occurred in 1 patient who underwent AM surgery. Conclusion AM surgery is effective, with lower complication rates and postoperative analgesic requirements, and is a less invasive treatment for patients with grade III hemorrhoids compared to DM surgery.

Purpose: External rectal prolapse (ERP) is frequently associated with other pelvic disorders, such as enterocele, rectocele, and perineal descent. Evacuation proctography makes it possible to visualize the development of such anatomical abnormalities. The aim of this study was to identify the variables that would predict associated abnormalities in patients with ERP. Methods: Between February 2010 and August 2019, 124 female patients with ERP, who were evaluated using proctography were included in this study. Enterocele was diagnosed when the extension of the loop of the small bowel was located between the vagina and rectum. A significant rectocele was defined as >20 mm in diameter. Multivariate analysis was used to establish which morphological parameters best predicted the presence of enterocele or rectocele. Results: Sixty-five patients had ERP alone, while 59 patients (47.6%) had additional findings on proctography. The most frequently associated abnormality was enterocele with 48 of the patients (38.7%) having this condition. Rectocele was detected in 17 of the 124 patients (13.7%). The median length of the ERP was 30 mm (range, 7 to 147 mm). The results of the stepwise multiple regression analysis showed that a history of hysterectomy and the length of the ERP were significantly associated with the presence of enterocele. The analysis showed that the longer the prolapse, the higher the incidence of enterocele. A history of hysterectomy was also significantly associated with the presence of rectocele. Conclusion Patients with ERP often have associated anatomical abnormalities and should be investigated thoroughly before planning surgical treatment.
