Increase in Lower Limb Strength After Multimodal Pain Therapy in Patients With Low Back Pain
Abstract Study DesignProspective Study DesignObjectivesThe aim of the present study was to evaluate the efficacy of a multimodal pain therapy (MPM) regarding the objective parameter muscle strength of segment-dependent lower limb muscle groups before and after such a treatment. Methods52 patients with a history of low back pain and/or leg pain received standardized multimodal pain management. Strength of segment indicating lower limb muscles were assessed for each patient before and after ten days of treatment by handheld dynamometry. ResultsOverall strength increased significantly from 23.6kg ± 6.6 prior to treatment to 25.4 ± 7.3 after treatment, p≤0.001. All muscle groups significantly increased in strength with exception of great toe extensors. ConclusionDespite lower basic strength values at the beginning of treatment, all investigated muscle groups, with the exception of the great toe extensors, showed a significant increase of overall strength after completion of the multimodal pain management concept. Increased overall strength could help with avoiding further need of medical care by supporting patients’ autonomy in daily life activities, as well as maintaining working abilities. Thus, our study is the first to show a significant positive influence on lower limb strength in patients with low back pain after a conservative MPM program.
