Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The lumbal multifidus muscle may be imaged by ultrasound, CT and MRI. Ultrasound is only suitable for superficial muscles and the resolution is low, which will lead to inferior tissue discrimination. CT and MRI have a highter resolution and therefore good tissue discrimination. Given the radiation exposure of CT, MRI is the most appriorate method for this study. The measurements will be performed by manually drawing the circumference of the muscle. Software will calculate the cross sectional area. Fat infiltration will be divided according to standard criteria: - Normal/mild (fat infiltration 10% and 50% of the cross sectional area) The functional cross-sectional area (FCSA) of the muscle will be calculated to quantify the condition of the muscle. The FCSA is the cross sectional area of the muscle isolated from fat. | — |
Secondary
| Measure | Time frame |
|---|---|
| To quantify the level of functional (ADL) limitations caused by low back pain, all participants will fill in validated questionaire at the time they undergo the MRI scans: the Roland-Morris Disability Questionnaire (RDQ) and the Patiënt Specifieke Klachten (PSK). Fysiotherapie MTG uses these questionaire for all patients. | — |
