Abstract

Aim: The aim of this quantitative study was to gather primary data to investigate whether an oscillatory technique applied to the lumbar spine has a short-term effect on pain pressure threshold (PPT) measurements of the lumbar erector spinae (LES) muscles. Design: A randomised controlled single-blind, non-cross over, unmatched experimental study. The experiment was conducted on a population of 50 asymptomatic students randomly recruited from the European School of Osteopathy. Participants were randomly divided into 2 groups of equal size, Experimental and Control. Method: The technique, consisting of a series of oscillations induced in the lumbar spine only, was applied to the Experimental group for 3 minutes. The Control group was required to lay down for the same duration. Data collection consisted of PPT measurements on 6 different locations on the lumbar paraspinal muscles, using a Wagner Force Dial FDK 40 analogue algometry. The readings were taken before and after the intervention by a second practitioner, which allowed for single-blind design. Ethical approval to conduct the study was obtained from the ESO Research Ethics Committee. Databases used: ScienceDirect SwetsWise, PubMed, Google Scholar, Academic Search Premier, CINAHL, JADA, IJOM, Elsevier-Science Journals Collection, etc. Search terms used: oscillatory OR harmonic AND technique AND osteopathy; oscillations AND manual AND therapy; lumbar AND paraspinal OR erector AN spinae AND muscles AND harmonic OR oscillatory; pain AND threshold AND measurements; pain AND pressure AND threshold; pain AND perception AND osteopathy; algometry AND osteopathy; algometry AND reliability OR validity. Hypotheses: The following on e-'tailed hypotheses were looking for a statistically significant decrease in PP I` of the LES in the treatment group after an oscillatory technique, compared to the control group. Experimental hypothesis: The application of an oscillatory technique to the lumbar spine will significantly decrease the pain pressure threshold measurements of the lumbar erector spinae muscles. Null hypothesis: The application of an oscillatory technique to the lumbar spine will NOT produce a significant difference in the pain pressure threshold measurements of the lumbar erector spinae muscles. Results: No significant statistical difference was found between the two groups overall. The perimental hypothesis hence had to be rejected in favour of the null hypothesis. Analysis: A Wilcoxon's Signed Rank Test was used to analyse the change in PPT respectively for the Control and Experimental groups, followed by a Mann-Whitney U test to compare the difference between the two groups. Discussion: The implications of this study for osteopathic medicine with regards to low back pain being the most prevalent complaint for which symptomatic individuals consult a primary care physician were discussed, as well as the extent to which the use of the oscillatory technique may thus be indicated in osteopathic treatment.Conclusion: This study concluded that application of the oscillatory technique to the lumbar spine did to show a local short term effect on PPTs. Suggestions were made for further research, as well as advice on limiting the possibility of future error.
