Summary

An interventional study aimed at verifying the effect of sacroiliac joint blockage on changes in piriformis muscle tension. The study was conducted on 40 subjects, both male and female. Physical therapy methods were used to diagnose muscle tension as a diagnostic tool, along with a visual analogue scale. The intervention was performed using manual mobilisation techniques commonly used in clinical practice. The effectiveness was verified using the same physical therapy diagnostic tool as at the beginning. The entire research process is time-consuming, taking up to 1 hour per examinee.

Detailed description

Objectives: The main aim of this study is to summarise current knowledge about the relationship between functional joint blockage and chained muscle spasm. To verify the relationship between sacroiliac joint blockage and piriformis muscle using combined therapy as a diagnostic tool, where the main parameter monitored will be the intensity of piriformis muscle irritability before and after sacroiliac joint mobilisation. Methods: Measurements will be taken on a group of 40 subjects. The research sample consists of people aged 18-60, randomly divided into an experimental and a control group. All subjects underwent an initial palpation examination of the piriformis muscle, during which the level of pain was determined on a numerical pain scale. All subjects then underwent measurement of the piriformis muscle's irritability threshold using the "Beauty-line device 4000 Topline" device. The experimental group then underwent therapeutic intervention in the form of sacroiliac joint mobilisation using the "Cluster of Lasslet" technique. This was followed by 30 minutes of relaxation. The control group received no therapeutic intervention and only 30 minutes of relaxation between the initial and final examinations. Both groups then underwent the same final examination as at the beginning. The investigators expect a change in piriformis muscle hypertonicity after sacroiliac joint mobilisation, including a reduction in pain in this muscle, at a statistical significance level of 5%.
