Purpose: This study was to evaluate the effect of cranio-cervical flexion based trunk stabilization exercise on gross motor function and posture alignment change in children with spastic cerebral palsy. Design: Randomized Controlled Trial. Methods: Twenty-six children participated in this study. All subjects were randomly assigned to either the Cranio-Cervical Flexion Based Trunk Stabilization Exercise (CCFTS) group (n=13) or the Trunk Stabilization Exercise (TS) group (n=13). In both groups were trained general physical therapy for 10 minutes, in the CCFTS group was trained cranio-cervical flexion based trunk stabilization exercise for 20 minutes and in the TS group was trained trunk stabilization exercise for 20 minutes. The training was provided 2 times a week during 8 weeks. All subjects were measured with the Gross Motor Function Measure (GMFM) and Cranio-Vertebral Angle (CVA) before and after intervention. Results: The results showed that the CCFTS have increased significantly in GMFM (B, C, D and E-dimension) and CVA, and the TS group have increased significantly in GMFM (B, C D and E-dimension). In particular, the CCFTS group improved significantly than TS group in GMFM (B, C and D-dimension) and CVA. Therefore, the cranio-cervical flexion based trunk stabilization exercise improved gross motor function and posture alignment in children with spastic cerebral palsy. Conclusion: These results suggest that cranio-cervical flexion based trunk stabilization exercise is feasible and suitable for individuals with a spastic cerebral palsy and can be used in addition to conventional physical therapy.

PURPOSE: This study aimed to investigate the benefits of thoracic manipulation and the trunk stability exercises on spine trunk flexibility and the pain index of chronic low back pain patients. METHODS: The study included 44 patients suffering from chronic low back pain. The participants were divided into two groups: the first group was assigned for trunk stability exercises (TSE), and the second group was randomly assigned TSE and thoracic manipulation at the same time (TSE+TM). Both groups carried out each assigned treatment thrice a week for 8 weeks. The study outcome was based on assessment of spine trunk flexibility and the pain index. Spine trunk flexibility was measured by spine flexion and extension through a range of motion and thoracic cage circumference. The pain index was measured using a visual analog scale (VAS). RESULTS: Spine flexion and extension range of motion showed a significant difference within each group and between the groups before and after the treatment. The measurement of the thoracic cage circumference also showed a notable difference within each group and between the groups before and after the treatment. There was no change in the pain index. CONCLUSION: These results indicate that thoracic manipulation with the trunk stability exercises is an efficient treatment for improving the spine trunk flexibility and soothing pain for chronic low back pain patients.

Background: The purpose of this study was to identify the effects of underwater and ground proprioceptive neuromuscular facilitation lower extremity pattern exercise on trunk control and lower extremity muscle activity of chronic stroke patients. Design: Pretest-posttest design: single blind. Methods: The subjects were 28 patients (experimental group, n=14 or control group, n=14) diagnosed with chronic stroke. The experimental group performed underwater proprioceptive neuromuscular facilitation lower extremity pattern exercise. The control group performed ground proprioceptive neuromuscular facilitation lower extremity pattern exercise. Training was conducted once a day for 30 minutes, five days per week for six. Trunk control was measured using the Trunk Impairment Scale. Lower extremity muscle activity was measured using surface electromyography. Results: As a result of comparison within groups, the experimental and control group showed significant difference for trunk control after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in trunk control than the control group (p<0.05). In comparison within groups, the experimental group showed significant difference for lower extremity muscle activity after the experiment (p<0.05). In comparison between two groups, the experimental group showed more significant difference in lower extremity muscle activity than the control group (p<0.05). Conclusion: Based on these results, underwater proprioceptive neuromuscular facilitation lower extremity pattern exercise effectively improved the trunk control and lower extremity muscle activity of chronic stroke patients.

Purpose: This study investigated the effects of trunk muscle activity with power grasping during one leg stance. Methods: Twenty-eight subjects participated in this study. Subjects were divided into two groups, one that performed power grasping, and another that did not. An investigator measured the activities of a subject's trunk muscle such as internal oblique (IO), external oblique (EO), erector spinae (ES), and gluteus medius (GM) while a subject was doing one leg stance. Results: An independent t-test was used to analyze trunk muscle activities with power grasping during one leg stance between the experimental group and the control group. Only the EO activity differed significantly between groups (p<0.05). Conclusion: The results indicate that one leg stance with power grasping affected trunk muscle activity. Therefore, this is a useful method for providing lumbar spine stability.

Membrane type LNG Carriers are characterized by their special structures such as trunk deck above upper deck. It is necessary to introduce an appropriate structure arrangement taking into account transition of the trunk deck to the upper deck or deckhouse in fore and aft parts. The transition area at aft part -from trunk deck to the deckhouse - is to be specially considered because of high longitudinal stresses applied at the area. This study has been carried out to tackle the transitional structure problem in design stage This paper deals with not only mesh size of FE models for scantling evaluation and fatigue assessment but also technical issues regarding fatigue assessment.

A sectional analysis of trunk-lid carried out by using the equilibrium approach based on the force balance together with geometric relations and plasticity theory. In computing a force balance equation, it is required to define a geometric curve approximating the shape of sheet metal at any step of deformation from the interaction between the die and the deformed sheet. The trunk-lid panel material is assumed to possess normal anisotropy and to obey Hill's new yield criterion. Deformation of each section of trunk-lid panel is simulated and composed to get the three-dimensional shape by using CAD technique. It was shown that the three-dimensional shape composition of the two-dimensional analysis.
