[Factors Modulating Motor Function Changes in Stroke Patients During Inpatient Neurological Rehabilitation]. / Welche Faktoren beeinflussen die motorischen Funktionsveränderungen bei Schlaganfall-Patienten während einer neurologischen Rehabilitationsbehandlung?

ABSTRACT

PURPOSE: To identify factors that have an impact on the degree of functional improvements in stroke patients during inpatient neurological rehabilitation. METHODS: Retrospective analysis of 398 stroke patients who participated in an inpatient Phase C rehabilitation (Barthel index between 30 and 70 points). We correlated changes in 3 physiotherapeutic assessments (transfer from sitting to standing; transfer from bed to (wheel)chair; climbing stairs) and 3 occupational therapeutic assessments (eating/drinking; dressing of the upper part of the body; object manipulation) with the factors age, gender, Barthel-Index at admission, time since stroke, length of stay in inpatient rehab, number and extent of therapies and ischemic versus hemorrhagic stroke. In addition, a stepwise regression analysis was performed. RESULTS: The patient group showed significant improvements in all assessments. Length of stay in inpatient rehab and number/extent of therapies correlated with improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, and dressing of the upper part of the body. Number/extent of therapies also correlated with eating/drinking. Barthel-Index at admission was negatively correlated with transfer from sitting to standing, transfer from bed to (wheel)chair, and dressing of the upper part of the body. No correlation between changes of motor functions and age or gender or type of stroke (ischemic versus hemorrhagic) was found. Patients<3 months after stroke showed stronger improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, dressing of the upper part of the body, and object manipulation than patients>6 months after stroke. However, patients<3 months after stroke also stayed 10 days longer in inpatient rehab. The stepwise regression analysis identified the number of physiotherapies and Barthel-Index at admission as the most important factors for changes in transfer from sitting to standing and transfer from bed to (wheel)chair, number of physiotherapies and time since stroke for climbing stairs, number of occupational therapies for eating/drinking, number of occupational therapies and time since stroke for dressing the upper part of the body and number of occupational therapies and length of inpatient rehab for object manipulation. CONCLUSION: In stroke patients, a higher number of therapies is associated with greater improvements of motor functions. Age, gender and type of stroke have no relevant impact on changes of motor functions during inpatient rehabilitation.
