OBJECTIVES: The purpose of this study was to identify the effects of aerobics and aquarobics exercise programs on elders' leg muscle strength, balance and walking ability in elders. The participants of the study were 21 elders; 11 of them participated in the aerobics exercise program and 10 of them participated in the aquarobic exercise program. METHODS: Both of the participants practiced for 10 weeks. The data were analyzed with using two-way ANOVA with repeated measures on the last factor. RESULTS: The results were summarized as follows: First, the main effect of exercise programs(aerobics x aquarobics) and the interaction effect between the exercise programs and the leg muscle strength were not significant. Second, the participants' static balance of the aquarobics exercise program increased more than that of the aerobics exercise program. Third, the participants' dynamic balance of the aquarobics exercise program increased more than that of the aerobics exercise program. Fourth, the main effect of exercise programs and the interaction effect between the exercise programs and the increase in gait speed were not significant. Fifth, the participants' step length of aquarobics exercise group increased more than that of the aerobics exercise program. All of the participants' leg muscle strength, static balance, dynamic balance, gait speed and step length increased after the both of two exercise programs. And, more importantly, the positive effect of the aquarobics exercise program on static balance, dynamic balance and step length was stronger than that of the aerobics exercise program. CONCLUSIONS: These results suggest that the aquarobics exercise program be more effective exercise on elders' balance and walking ability than the aerobics exercise program.

Cubitus varus is a complex three-dimentsional deformity. In addition to deformity on varus-valgus plane, internal torsion of distal humerus is frequently combined. Also limitation of flexion-extension could be associated in some patients. Surgical correction of the cubitus varus after skeletal maturity, could have some different clinical course from those of growing children. However there have been few papers dealing with the surgical treatment of cubitus varus in adults. From May 1988 to December 1993, 23 patients who were older than 17 years of age, had correc- tive osteotomy for cubitus varus considering its three planes of the deformity at Seoul National University Hospital. To prevent serpentine deformity medial displacement of distal fragment was also combined during operation. The avereage age was 26 years(17-47), and the average follow-up after the operation was 1 year and 6 months(6 months-3 years). The presumed diagnosis of initial injury deduced from history and preoperative radiograms, was supracondylar fracture in 19 cases(86.4%). Others were lateral condylar fracture of humerus in two, and fractures associated with elbow dislocation in two. The average age at the time of initial injury was 8 years(2-14), and average delay from occurrence of deformity to the operation, were 13 years. Tardy ulnar nerve palsy was associated in 3 cases(13.6%). The preoperative average angle of cubitus varus was 26 degrees(16-45), flexion contracture 11 degrees(-5

Rectus sheath hematoma of the abdominal wall is a well-recognized, but uncommon condition, caused by a tear in an epigastric vessel and characterized by sudden onset of severe abdominal pain and palpable mass. In most cases, a precipitating cause can be demonstrated. Causes include external trauma, strenuous activities, coughing, lifting, sneezing, vomiting, straining while urinating or defecating, golfing, pregnancy and the puerperium, anticoagulation therapy, infection, chronic diesase, arteriosclerosis, hypertension, prior paracentesis or laparotomy, inadequate hemostasis or excessive retraction in surgery, and idiopathy. Unfortunately, the correct diagnosis often is missed, and the hematoma is found only during an exploratory laparotomy. Treatment should be conservative in most instances. Although the mortality rate for patients with rectus sheath hematoma is low, the condition may be fatal if the volume of the hemorrhage is large and if treatment is delayed. Hence, it should be included in the differential diagnosis of any patient who presents to the emergency department with acute onset of abdominal pain. Our purpose is to familiarlize emergency physicians with the pathophysiology, the diagnosis, and the treatment of rectus sheath hematoma. We describe a patient with fatal rectus sheath hematoma presenting to the emergency department and give a review of the literature.

OBJECTS: Thls study was designed to assess muscle tensions while working at a YDT workstation with surface electromyography (SEMG). METHODS: Variables texted were desk height, monitor positon on the desk, distance from edge of the desk to the keyboard. Eleven female volunteers working in the tele-com munication company were seated at an ergonomically adjusted workstation. They were assigned to a task of typing for 5 minutes and were given a 10 minutes resting with hands in their lap. For the initial experiment, the desk height was fixed to standard desk height(65.0 cm) recommended by ANSI and latter adjusted to a higher desk height (72.8 cm) for this study such that the subjects experienced slight elevation of shoulders. The monitor position initially at the center on the desk and latter left site of the desk (45o from monitorneck axles). The keyboard was positioned to an optimal distance (15 cm from the desk edge) and an abnormal distance (30 cm). Five muscle groups (paraspinal muscles, upper trapezium muscle, supraspinatus muscle, infraspinatus muscle, and rhomboid muscle) were selected for the study. The data of SEMG were analyzed by 2x2x2xs mixed factorial design. RESULTS: The results were as follows: 1. SEMG activity recorded from the paraspinal muscles were significantly higher when the angle of the monitor adjusted to 45 degree from the center of the desk.. 2. SEMG activity recorded from the upper trapezius/supraspinatus/infraspinatus muscles were significantly higher when the hight of the desk was elevated from the recommended height.3. SEMG activity from the rhomboid muscle showed no significantiy difference in all test conditions. CONCLUSIONS: The results of thls study confirm that the helght of a VDT workstation and the angle of the monitor are risk factors of upper extremity cumulative trauma disorders. Also SEMG would be useful for measuring muscle activities during workstation assessment.

PURPOSE: In contracted bladder of various etiologies, if many of conservative managements fail, a surgical treatment seems to be the only therapeutic approach. We tried to evaluate the long term results of aug mentation cystoplasty including the postoperative complication and the degree of satisfaction in patients. MATERIALS AND METHODS: From 1989 to 1988, augmentation cystoplasties had been performed in 11 patients with contracted bladder of various etiologies. We reviewed the patients' medical records including the result of urodynamic examinations, retrospectively. Postoperative follow-up periods were 9 to 114months (mean:61months). Patients were interviewed by telephone. RESULTS: Urinary frequency, nocturia, dysuria and suprapubic pain were improved in all patients, but dysuria persisted in one patient with tuberculous cystitis. Clean intermittent catheterization (CIC) was done in there of 11 patients due to large volume of residual urine. The volume of residual urine was 200-300ml in one with hyperreflexic neurogenic bladder, and 100-200ml in two with interstitial cystitis. Self voiding was possible in 8 patients with residual urine volume less than 90ml. Almost all patients were very satisfied symptomatically in the telephone survey. There were no significant complications which required surgical revision. CONCLUSIONS: It is concluded that augmentation cystoplasty could be an excellent method of treatment for selective patients with contracted bladder, who have not improved symtomatically by medication or conservative management.
