The research deals with the theoretical analysis of the causes for occurring back pain as well as the investigation of the factors predetermining back stability, ways of prophylaxis and rehabilitation. The hypothesis stating that the back pain will decrease after the back stability training programme has been formulated. The research methods: questionnaire-based survey, experiment, testing, statistical analysis of research results (descriptive analysis of frequencies, averages, standard deviations). By the Spearman’s correlation coefficient, the linear dependence of the variables was estimated. The data was considered as reliable when p < 0.01; and p < 0.05. 18 women working at Šiauliai University took part in the research. The surveyed were selected by the non-probability way of group formation. The experimental group (EG) encompassed women complaining about the back pain, and the control group (CG) consisted of those not experiencing the back pain as an indicator of external factors that can impact appearance of the back pain. The empirical part deals with the changes of the back pain and waist muscles’ endurance when applying the back stability training programme. Research results: 1. During the experiment, we have estimated that the back pain of the EG participants had decreased after the back stability training programme, the functional capacities increased (r = 0.725, p <0.05). The CG participants did not complain about back pains at the beginning of the research; however, at the end of the research, some participants noted that the back pain occurred and functional capacities decreased (intensity of the pain was 1.87 points, r = 0.712, p = 0.031) 2. After comparison of static endurance of side muscles of both CG and EG participants before the programme, the endurance of the CG participants’ muscles was higher than of the EG participants; however, after the programme, the endurance of the EG participants’ muscles increased (p< 0.05). For the CG participants, the asymmetry between the right and left side waist muscles was estimated as well as decrease of endurance of back muscles which can be the cause for the back pain to appear. 3. Before the programme, the results of waist stability tests (by using the device “Stabilizer”) of both EG and CG participants showed that back and abdominal deep muscles ensuring back stability were insufficiently enduring. After the back stability training programme, the EG participants’ endurance of these muscles increased (p< 0.05), and the results of the CG participants changed very slightly, not reaching the set norm; we may suppose that improperly trained muscles do not perform the function of core stabilisation, the increase of back pain can be possible. |
