- Abstract
- Background: L3 is often looked at as the centre of gravity of the body due to its role in linking the lower extremity to the torso via the psoas muscle and the crura of the diaphragm. However, research papers on that subject are lacking, especially experimental studies. This suggests there is a significant gap in research as osteopaths in training are being taught to see this Keystone as playing a major role in viewing the body as a whole. Aims and Objectives: the aim of this study is to answer the question of whether L3 plays a role as a centre of gravity in the human body. The objective of this study is to determine whether a High Velocity Thrust (HVT) of L3 affects the balance of an individual in comparison to proprioceptive exercise. Hypothesis and null hypothesis: H1: HVT of L3 significantly affects sway. H1o: HVT of L3 does not significantly affect sway' H2: Proprioceptive exercises significantly affect sway. H20: Proprioceptive exercises do not significantly affect sway. H3: There is a significant difference between the HVT and exercise groups in the effect on sway. H3o: There is no significant difference between the HVT and exercise groups in the effect on sway.Design: Matched control study Method: Participants included willing ESO students from allyears. Candidates were invited to volunteer verbally after having received and read an information form detailing the experimental process. The lnclusion and Exclusion criteria were based of Stoddard's relative and absolute contraindications for manipulation (2001 ).The allocation of groups was made via a matched control approach therefore the first 14 participants were chosen at random and the following 14 were selected based on their matchinq characteristics rnith the first group. Statistical tests were run with a significance levei of Scn and a confidence of 95%. At the beginning of the experiment, participants were asked to stand on a balance board to take three measurements of balance (sway). The exercise group then had three weeks of autonomous exercising while the HVT group were followed by an osteopath in their fourth year of training to receive an osteopathic manipulation on the L3 once a week for three weeks. At the end of the three weeks, participants were asked to step once more on the balance board for a final three measurements. Results: 28 participants were analysed for baseline characteristics and outcome measures using Analyse-lT 3.9 add-on software to test the experimental hypotheses and to analyse the data. The ANOVA test showed no statistical difference in balance either within or between groups as the p-value was 0.2224, hence larger than the 5% significance level. Conclusion: The present study shows that manipulating the L3 vertebra compared with exercise did not prove to be statistically significant in terms of affecting balance (sway). Further research is needed over a longer period of time and on a more varied subject pool.
