The aim: to evaluate the application of ergonomic efficiency, educating primary school students writing skills after upper extremity injuries. Work tasks: 1.Evaluate the effectiveness of ergonomic writing positions writing quality. 2.Rate finger muscle strength and manual dexterity before and after rehabilitation. 3.Investigate felt pain while writing the change after rehabilitation. 4.Identify statistically significant abnormal physical indicators of the impact of the quality of writing . Methods. A total number of 64 patients with a dominant hand injury and writing skills disorders, of which 41 (64 percent) boys and 23 (36 percent) girls took part in the research. Research methods. The study took place in the public institution of Vilnius University Hospital Branch, Children's Hospital, since 2014, December to the year of 2016, January. The patients were divided into two groups - a control group, that has subjected occupational therapy treatment, and the research group in which occupational therapy procedures were the subject to the application of ergonomic writing positions and principles and presentation of visual material on the table work ergonomics. In the research group participated 32 (50%) of children in the control - 32 (50%). Subjects were tested twice. The studies of the patients’ writing skills were evaluated by" Writing Skills Test; manual dexterity assess - Purdue pegboard test; the fingers muscular strength measuring - Hydraulic finger pinch strength meter, to assess pain - Wong-Baker scale. Data analysis was performed using the statistical analysis of the “R Commander 3.0.2 i386.” and “Excel 2013” program. Results. After rehabilitation in the study writting skils between group compared with the control significantly (p <0.05) improved: the choice of instruments, paper direction, detention pens, pens compression, letter formation, letter writing direction. The evaluation damaged sleight of hand, the analysis of groups of test pins average performance, it was found that the control group, a result of improved average 1,98 towers, improvement in the study group averaged 2.95. After analyzing the results of the test groups turret average it was found that the control group, a result of improved average of 1.62 seconds, an improvement in the study group averaged 2.21 seconds. Summarizing all the muscle force measurements showed that a statistically significant difference between the groups (p> 0.05). Before the rehabilitation of a three measurements of the rate of the control group reached the 1 investigation, after rehabilitation –3. In research before rehabilitation - none researched after rehabilitation - the third. After analyzing the results of pain in both groups after rehabilitation pain decreased. It was found that the change between the groups is statistically significant (p <0.05). It was found that the quality of writing and felt pain there is a strong correlation. The linear regression equation showed that the writing quality is inversely proportional to pain. The pain is felt in the higher and the lower writing skills. Conclusions 1.Ergonomic factors have affected 7 of 10 writing evaluation criteria. Ergonomic writing positions are effective in education of children’s writing skills. 2.The assessment of manual dexterity in the study group to get slightly better results. It can be assumed that better results were ergonomic posture. 3.Results of the pain feel experimental group after occupational therapy sessions differed significantly compared to the control group. Ergonomic elements of customization and ergonomic to reduce muscle tension and joint load. 4.Based on the results it was established as a pain affects the quality of writing. The results reflect inversely proportional influence: decreasing pain felt while writing is improving. A reduction in perceived pain ergonomic positions and indirectly affected by the quality of writing. |
