Summary

The objective of the study is to measure and analyse the effect of a spinal mobilisation intervention on muscle tissue quality in people with lower back pain. The mobilisation intervention will be compared to a control with participants taking part in both conditions for a factorial, within-subject repeated measures study. The study will analyse lumbar muscle response to the manual intervention and analyse the potential influence of anthropometric measures of participants. The study hypothesises a decrease in lumbar stiffness post the intervention, compared to the control session.

Detailed description

Various types of spinal manual therapies have been common practice for many years, particularly for treatment of lower back pain. Spinal mobilisation is a specific technique within spinal physiotherapy, often used as a treatment for lower back pain. This is despite limited objective evidence of the effect on muscle tissue quality. The objective of this study is to measure and analyse the acute effect of a spinal mobilisation intervention on muscle tissue quality in people with lower back pain. The intervention consists of the mobilisation of the lumbar spine for 30 minutes, at a specific rate and pressure. This will be performed by a chartered physiotherapist. This will be tested with 40 participants with lower back pain. This was the recommended sample size given by G Power for a medium effect size, a power of 0.95 and alpha level of 0.05. Participants will take part in an intervention and a control condition. Lumbar muscle response will be measured for stiffness, tone and elasticity immediately before and after the intervention and the control. The control session consists of lying still for the 30 minutes. Results for both sessions will then be compared. A myometer (MyotonPRO) will be used to assess the change in lumbar muscle objectively. This is a non-invasive, handheld device with many reliability studies on its functionality. Analysis will consider the degree of muscle response with individual covariates involved. This includes gender, height, weight, waist circumference, BMI and level of back pain (discerned by score on Oswestry Disability Index). The results will compared in 2-way repeated measures, within participant ANOVA for significant differences between conditions and time. Anthropometric measures will be analysed in separate ANOCOVAs to determine any significant factors contributing to level of change.
