ObjectiveTo evaluate effects of caregiver's education program on their satisfaction, as well as patient functional recovery, performed in addition to daily conventional rehabilitation treatment.MethodsThree hundred eleven subjects diagnosed with first-onset stroke and transferred to the Department of Physical Medicine and Rehabilitation of Inha University Hospital were surveyed. In 2015, caregivers attended an education program for acute and subacute stroke patients. Patients who received an additional rehabilitation therapy were assigned to the experimental group (n=81), whereas the control group (n=100) consisted of transfer cases in 2014 with only conventional treatment. The experimental group was classified by severity using the Korean version of the National Institutes of Health Stroke Scale (K-NIHSS), which was administered to all 181 subjects, in addition to, the Korean version of the Mini Mental Status Examination (K-MMSE), a Modified Barthel Index (K-MBI), and the Berg Balance Scale (K-BBS). Caregiver satisfaction and burden before and after education programs were assessed using the Canadian Occupational Performance Measure (COPM), as well as family burden and caregiver burnout scales.ResultsNo significant intergroup difference was observed between initial K-NIHSS, K-MMSE, K-BBS, K-MBI scores, and times from admission to transfer. Those with moderate or severe strokes under the experimental condition showed a more significant improvement than the control group as determined by the K-NIHSS and K-BBS, as well as tendential K-MMSE and K-MBI score increases. Satisfaction was significantly greater for family members and formal caregivers of patients with strokes of moderate severity in the experimental group.ConclusionThe caregiver's education program for stroke subjects had a positive outcome on patients' functional improvement and caregiver satisfaction. The authors believe that the additional rehabilitation therapy with the education program aids patients to achieve functional improvements for an optimal return to social life.
ObjectiveTo clarify the relationship of the initial radiologic and a biomechanical parameter at first clinical visit, and define the effectiveness of modified insole, following insole fitting in children with flexible flatfoot.MethodsChildren aged less than 13 years with flexible flatfoot were enrolled. The total number of subjects was 66 (33 boys, 33 girls). The subjects were divided into 5 subgroups, based on age: 1–2, 3–4, 5–6, 7–9, and 10–12 years. The mean time period between the initial & final examination for their resting calcaneal stance position angle (RCSPA) was 24 months. Radiography quantified the deformity by measuring angles, including the talometatarsal angle, the metatarsal angle, and the calcaneal pitch angle.ResultsFrom the angles measured on radiographs, only the talometatarsal angle showed a statistically significant correlation to the initial RCSPA (r=-0.578 for right side, r=-0.524 for left side; p<0.01). The mean RCSPA improved in all subgroups of subjects following insole fitting. Moreover, in children younger than 7 years, the improvement in RCSPA from the insole fitting was greater compared to children aged 7 years and older.ConclusionThe insole has additionally beneficial effects in all populations younger than 13 years. However, there might exist a hidden effect of normal structural pedal alignment during growth accompanied with bony maturation and developmental process. To date, it is controversial whether the treatment of flexible flatfoot is necessary in the vast majority of cases, or simple observation and advice to parents would suffice.
ObjectiveTo evaluate the effects of early regular exercise and to assess the electrophysiological and histopathological findings of the rat tail nerve in relation to the timing of exercise training for swimming exercise in rats with diabetic neuropathy.MethodsWe used 70 Sprague-Dawley male rats, and the experimental group comprised 60 rats, and the control group comprised 10 rats. Diabetes was induced by intraperitoneal injection of streptozotocin. Blood glucose concentrations were measured in tail vein blood samples. The experimental group was divided into 6 subgroups according to insulin treatment and swimming exercise: group 1, diabetic control; group 2, insulin treated; group 3, insulin untreated with early swimming exercise; group 4, insulin treated and early swimming exercise; group 5, insulin treated and late swimming exercise; and group 6, insulin untreated with late swimming exercise. Sensory and motor nerve conduction studies were performed weekly up to the 13th week using rat tail nerves. The effect on structural diabetic neuropathy was assessed by morphometry and ultrastructural examination of the rat tail nerve fiber at the 14th week.ResultsAn exercise effect was observed in the insulin treated groups, but it was not observed in the insulin untreated groups. The sensory nerve conduction study in the rat tail revealed significantly prolonged latency and decreased amplitude in groups 1 and 6, and a further delay was observed in group 5 when compared to group 4. Decreased thickness of myelin was found in groups 1 and 6 through morphometry.ConclusionEarly regular exercise programs in addition to conventional insulin treatment may retard the progression of diabetic peripheral neuropathy.
With concern for new renewable energy sources rising, the offshore wind turbine energy market is growing. In order to install offshore wind turbines safely in a harsh environment, jack-up rigs need to be used. Recently, a WTIV(Wind Turbine Installation Vessel), which has a self-propelling system, was developed to replace traditional jack-up rigs. Since the jack-up rig works at 60 meters of depth in offshore and the seafloor is composed mostly of soft clay and sand, it is necessary to conduct a stability examination for ground subsidence before using it. This study conducts an improved numerical analysis of the effect of jack-up rig loading on the soft ground by using FLAC3D considering consolidation theory. This includes analyzing the amount of subsidence when applying different cases of surchargings. It can be concluded that the mid-loading method has an advantage as regards clay layers and the pre-loading method has an advantage as regards sand layers.
