ABSTRACT
OBJECTIVE: To compare the convenience and effectiveness of the existing lumbosacral orthoses (LSO) (classic LSO and Cybertech) and a newly developed LSO (V-LSO) by analyzing postoperative data. METHODS: This prospective cohort study was performed from May 2019 to November 2019 and enrolled and analyzed 88 patients with degenerative lumbar spine disease scheduled for elective lumbar surgery. Three types of LSO that were provided according to the time of patient registration were applied for 6 weeks. Patients were randomized into the classic LSO group (n=31), Cybertech group (n=26), and V-LSO group (n=31). All patients were assessed using the Oswestry Disability Index (ODI) preoperatively and underwent plain lumbar radiography (anteroposterior and lateral views) 10 days postoperatively. Lumbar lordosis (LS angle) and frontal imbalance were measured with and without LSO. At the sixth postoperative week, a follow-up assessment with the ODI and orthosis questionnaire was conducted. RESULTS: No significant differences were found among the three groups in terms of the LS angle, frontal imbalance, ODI, and orthosis questionnaire results. When the change in the LS angle and frontal imbalance toward the reference value was defined as a positive change with and without LSO, the rate of positive change was significantly different in the V-LSO group (LS angle: 41.94% vs. 61.54% vs. 83.87%; p=0.003). CONCLUSION: The newly developed LSO showed no difference regarding its effectiveness and compliance when compared with the existing LSO, but it was more effective in correcting lumbar lordosis.
ABSTRACT
OBJECTIVE: To determine correlation of the Korean version of Falls Efficacy Scale-International (KFES-I) with other gait and balance parameters through exercise program in older men. METHODS: Between July 2015 and April 2018, 50 men of 103 participants in an exercise program for preventing falls who aged over 60 years, completed the evaluation before and after the program, had fear of falling (FOF), and could walk independently as an outpatient were enrolled retrospectively. The program comprised lower extremities and core muscle strengthening exercises following stretching exercises twice a week for 8 weeks. FOF using the KFES-I, Berg Balance Scale (BBS), Modified Barthel Index (MBI), stair up and gait categories in MBI (MBI-gait), and Timed Up and Go test (TUG) were evaluated. Quantitative gait and balance parameters were measured by gait analysis, posturography, and isokinetic dynamometer. They were compared before and after the program. Moreover, correlations of KFES-I with other parameters were examined. RESULTS: Fifty participants were enrolled. After the program, significant improvements were noted in right stride length (p=0.013) in gait analysis, MBI (p=0.012), BBS (p<0.000), TUG test (p<0.000), and KFES-I (p<0.000) scores. KFES-I was significantly correlated with MBI (r=-0.35, p=0.013), and MBI-gait (r=-0.341, p=0.015). CONCLUSION: Risk of falls could be significantly improved through exercise. KFES-I had significant correlations with MBI-gait parameters. Participants showed increases in gait and balancing ability on quantitative measurements through exercises. Therefore, regular stretching, strengthening, and balancing exercises may help prevent falls in older people.
ABSTRACT
Effects of the ethanol extract of Cichorium intybus (CIEE) on the immunotoxicity of ethanol (EtOH) were investigated in ICR mice. Mice were divided into four groups, and CIEE at dose of 300 mg/kg was orally administered to mice daily for 28 consecutive days, and normal mice were given vehicle. Mice treated with EtOH were given freely with 20% w/v EtOH solution. The results of this study are summarized as follows: The combination of CIEE and EtOH showed significant increases in the circulating leukocytes and the relative weights of liver, spleen and thymus, as compared with those in mice treated with EtOH alone. However, the body weight gain was not affected. Splenic plaque forming cells (PFC) and hemagglutination (HA) titers to sheep red blood cells (SRBC), and the secondary IgG antibody response to bovine serum albumin (BSA) were markedly enhanced by CIEE plus EtOH treatment as compared with the treatment of EtOH alone. In mice receiving the combination of CIEE and EtOH when compared with EtOH alone-treated mice, there were also significant increases in delayed-type hypersensitivity (DTH) reaction, phagocytic activity, natural killer (NK) cell activity and cell proliferation as well as interferony (IFN-gamma) secretion. In the case of interleukin-4 (IL-4) content, however, an insignificant induction observed by CIEE plus EtOH treatment. These findings indicate that the immunotoxicity induced by EtOH is significantly restored or prevented by CIEE treatment.
