studies of patients with non specific low back pain and movement control dysfunctions are of great interest. Future research could also address whether there is a differencebetween the range of motion in negative and positive tests to see if these patients also have a hypermobility as it could be hypothesized by a clinical instability. Table 1 gives an overview of the reliability studies published before. Similarly, extension movement control is assessed in the tests "pelvic tilt "rocking all four forwards" and "prone knee bending" where the subject should extend the hip while the lumbar spine is stabilized. It is assumed that MC can be inferred from movement behaviour exhibited with the six tests. The ES (d) is the difference of the means divided by the mean standard deviation of the groups. Patients with chronic LBP have significantly more positive tests than those with acute or subacute LBP. 1992, 5 (4 383-9. This is the first study demonstrating a significant difference between patients with LBP and subjects without back pain regarding their ability to actively control the movements of the low back. The face validity of the six direction specific tests in this study (see Figures 1 2 ) is supported by the following considerations. 16 examined ten movement control tests for the back. The aim of this study was to determine whether the number of positive tests out of six active MC tests was different in patients with a wide time range (acute, sub-acute and chronic) of diagnosed LBP compared with healthy controls and to determine the effect. EdB was involved in the planning of the study, methodological considerations, and critically revised the manuscript for its content. Van Dillen. Movement Control, clinical Instability, neural Control System, back Pain Problem. A copy of the written consent is available for review by the Editor in Chief of this journal. Inclusion criteria for patients were non-specific low back pain (nslbp and to have been referred to physiotherapy by a physician due to the back pain. Criteria were discussed and typical dysfunctions were presented. In the past, kinesiopathologic movement patterns in the lumbar spine have been investigated and described 1 5, resulting in the publication of both reliability and validation studies of the examination procedures used. Choosing the level of significance as alpha.05 and power (beta.80) for testing Ho: Group1 Group2 versus H1: Group1Group2, the required sample size for group testing would be 99 cases per group for an effect size of.5. It appears that the longer the symptoms of LBP last, the worse the movement control becomes.

This might have introduced a major bias in the results as the clinicians may have been influenced in their judgments by their expectations.Figure 3 Number of positive tests in the two groups.
