Zusammenfassung

Hintergrund

Ziel der Studie war die Untersuchung der posturalen Kontrolle während externer über die Füße eingeleiteter Störungen bei Patienten mit chronischem nichtspezifischem Rückenschmerz (CNRS). Zudem wurde der Einfluss der visuellen Information (Augen offen vs. Augen geschlossen) auf die posturale Kontrolle untersucht.

Material und Methoden

Es wurden 8 Patienten mit CNRS (Alter: 40±12 Jahre; Body Mass Index, BMI: 23±2 kg/m2) ohne degenerative Bandscheibenerkrankung der Wirbelsäule (Befund der Magnetresonanztomografie) und 12 gesunde Vergleichspersonen (Alter: 28±7 Jahre; BMI: 21±3 kg/m2) untersucht. Mittels Oberflächenelektromyografie (OEMG) wurde die posturale Kontrolle bei 5 Rumpf- und 5 Beinmuskeln sowie einem Beckenmuskel bei distalen lateralen Störungen analysiert.

Ergebnisse

Gesunde (Mittelwert ± Standardabweichung: 96,42±64,77 µV) zeigten im Vergleich zu Patienten mit CNRS (56,29±39,63 µV) eine signifikant (F=6,00; p<0,05) größere erste Maximalamplitude der muskulären Reflexantwort des M. gluteus medius während externer Störungen im aufrechten Stand. Beide Gruppen zeigten für ausgewählte Beinmuskeln ein signifikant größeres Integral der ersten Reflexantwort bei geschlossenen Augen im Vergleich zu offenen Augen.

Schlussfolgerung

Patienten mit CNRS zeigen eine veränderte reflektorische Antwort des M. gluteus medius, welche mit einer verminderten Beckenstabilisierung einhergehen könnte.

Altered hip muscle activation in patients with chronic non-specific low back pain

Abstract

Background

The aim of this study was to examine postural control in patients with chronic non-specific low back pain (CNRS). Furthermore the influence of visual information (eyes open versus eyes closed) was analyzed.

Material and methods

A total of 8 patients with CNRS and 12 healthy control subjects were examined. Surface electromyography (SEMG) recordings were made from 5 trunk and 5 lower limb muscles as well as one hip muscle during application of distal lateral perturbation.

Results

Healthy controls (mean ± standard deviation: 96.42±64.77 µV) showed a significantly higher maximum amplitude of the gluteus medius muscle in comparison to patients with CNRS (56.29±39.63 µV). Furthermore activation of several lower limb muscles was found to be dependent on visual information.

Conclusion

Patients showed an altered reflex response of the gluteus medius muscle which could be associated with reduced hip stability.
