Bewegungskontrolldysfunktion als Subgruppe von unspezifischen Rückenschmerzen

«Erworben im Rahmen der Schweizer Nationallizenzen (http://www.nationallizenzen.ch)»Schmerzen des untere Rückens sind meist unspezifisch, d. h. es gibt keinen spezifischen medizinischen Grund für die Schmerzen. Eine Subgruppierung unspezifischer Rückenschmerzen wurde deswegen als einer der wichtigsten Forschungsschwerpunkte genannt. Eine mögliche Subgruppe ist die Bewegungskontrolldysfunktion, bei der der Patient seine Bewegungen nicht bewusst kontrollieren kann. Eine Testbatterie wurde entwickelt und validiert, um diese Patientengruppe zu untersuchen und zu behandeln. Sie besteht aus 6 Bewegungstests und wurde als reliabel bewertet. Mit diesem Testverfahren können Personen mit Rückenschmerzen zuverlässig von gesunden Personen unterschieden werden. Ebenfalls untersucht wurde der Zusammenhang mit der Körperwahrnehmung. Dabei zeigte sich, dass Zweipunktdiskriminationsfähigkeit mit der verschlechterten Bewegungskontrolle des Rückens korreliert. Eine Fallserienstudie (n=38) ergab, dass diesen Patienten mit spezifischen Übungen gut geholfen werden kann. Da es in dieser Studie keine Kontrollgruppe gab, kann jedoch eine Kausalität nicht hergestellt werden. Low back pain (LBP) is in most cases non-specific, meaning that there is no clear medical cause for the problem. Subgrouping of these patients has been declared as one of main research areas of LBP. One possible subgroup of LBP is movement control dysfunction which means that patients cannot actively control movements of the lower back. A test battery consisting of six movement control tests was created to examine this dysfunction and was found to be reliable. The test battery can discriminate between patients with LBP and healthy controls. It was also shown that patients with movement control deficits have a distorted body image which can be measured with two-point discrimination tests. In a case series study (n = 38) patients with movement control dysfunction could be extensively improved in their disability, pain and function. However, as there was no control group in the study no causal conclusions can be drawn

Movement control exercise versus general exercise to reduce disability in patients with low back pain and movement control impairment. A randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>Non-specific low back pain (NSLBP) in subacute and chronic stages can be treated effectively with exercise therapy. Research guidelines recommend evaluating different treatments in defined subgroups of patients with NSLBP. A subgroup of patients with movement control impairment (MCI) improved significantly on patient specific function and disability in a previous case series after movement control exercises.</p> <p>Methods/Design</p> <p>In a randomised controlled trial (RCT) we will compare the effectiveness of movement control and general exercise in patients with MCI. 106 participants aged 18 - 75 will be recruited in 5 outpatient hospital departments and 7 private practices.</p> <p>Patients randomly assigned to the movement control exercise group will be instructed to perform exercises according to their MCI. The general exercise group will follow an exercise protocol aimed at improving endurance and flexibility. Patients in both groups will receive 9 - 18 treatments and will be instructed to do additional exercises at home.</p> <p>The primary outcome is the level of disability assessed using the patient specific functional scale (PSFS) which links the perceived pain to functional situations and is measured before treatment and at 6 and 12 months follow-up. Secondary outcomes concern low back pain related disability (Roland Morris questionnaire, RMQ), graded chronic pain scale (GCPS), range of motion and tactile acuity.</p> <p>Discussion</p> <p>To our knowledge this study will be the first to compare two exercise programs for a specific subgroup of patients with NSLBP and MCI. Results of this study will provide insight into the effectiveness of movement control exercise and contribute to our understanding of the mechanisms behind MCI and its relation to NSLBP.</p> <p>Trial registration</p> <p>Current Controlled Trials <a href="http://www.controlled-trials.com/ISRCTN80064281">ISRCTN80064281</a></p

Specific or non-specific exercises for patients with low back pain and movement control impairment : what works?

Low back pain (LBP) is a common disease. In most cases the cause of the pain is unknown. If the pain is related to altered movement patterns, a movement control impairment (MCI) can be diagnosed. Regular, specific or non-specific exercises over one year can improve function and pain in patients with LBP and MCI. The exercises are instructed by a physiotherapist in 9–18 treatments. This is followed by a home-exercise program twice or more times per week for the following year. Patients identified increased confidence, easily understandable exercises and a combination of exercises with self-initiated physical activity as motivational strategies to keep up with the home-exercises

Construct Validity and Validity to Change of the Patient- Specific Functional Scale in Patients with Shoulder and Low Back Pain: A Clinimetric Study

Background: Patient-specific and condition-specific measures are widely used in clinical practice and research to measure disability or change over time. While condition-specific outcome measures comprise a range of restrictions generally relevant for all patients, the Patient-Specific Functional Scale measures restrictions chosen by the individual patient. Objectives: Based on the hypothesis that patient-specific and conditionspecific scales deliver comparable results when used on group level. The aim of this study was to test for floor and ceiling effects, to evaluate construct validity and validity to change of the Patient-Specific Functional Scale when compared to condition-specific outcome measures. For this purpose, two datasets from patients with shoulder pain and low back pain were analyzed. Methods: Patient-Specific Functional Scale scores were compared to the Shoulder Pain and Disability Index and the Roland Morris Disability Questionnaire at 4 time-points using stem-and-leaf-plots and correlations using Pearson’s r. Hypothesis-driven correlation levels for data interpretation were predefined, with r ≥0.75=high, r ≥0.5=moderate, r ≥0.25=low. Results: Patient-Specific Functional Scale floor effects were comparable to condition-specific outcome measures in both samples. At none of the timepoints did the Patient-Specific Functional Scale correlate with the conditionspecific outcome measures in the expected manner. Conclusion: Hypotheses regarding expected ranges of correlation between the Patient-Specific Functional Scale and the condition-specific outcome measures for construct validity and validity to change were not met. While the use of the Patient-Specific Functional Scale in a clinical context has its advantages, the measure is not recommended for group-level evaluations
