Effect of Whole-body Vibration Combined with Task Oriented Training on Muscle Strength, Balance, and Gait in Stroke Patients with Hemiplegia: A Pilot Randomized Controlled Trial

Abstract

The current study aimed to evaluate the effects of whole-body vibration combined with task-oriented training on muscle strength, balance, and gait in stroke patients with hemiplegia. In total, 24 stroke patients were included in this study. All participants were randomly assigned to either the whole-body vibration combined with task-oriented training group (n=12) or the whole-body vibration group (n=12). The WBVMT group underwent training (8 sets) for 30 min a day, 5 times per week for 4 weeks. Meanwhile, the WBV group underwent training (8 sets) for 30 min a day, 5 times per week for 4 weeks. Both groups received standard rehabilitation physical therapy for 60 min a day, 5 times a week for 4 weeks. In all participants, the scores for the hip extensor (HE) and knee extensor (KE) muscle strength, Five Times Sit-to-Stand (FTSTS) Test, limit of stability (LOS), Timed Up and Go (TUG) Test, Berg Balance Scale (BBS), 10-Meter Walk Test (10MWT), and 6-Min Walk Test (6MWT) were evaluated before and after the intervention. The WBVMT and WBV groups had a significant increase in the scores for HE and KE strength, FTSTS test, LOS, TUG test, BBS, 10MWT, and 6MWT (p<0.05). In particular, the WBVMT group had a significantly greater improvement than the WBV group in terms of KE muscle strength and TUG test, BBS, 10MWT, and 6MWT scores (p<0.05). WBVMT improved muscle strength, balance, and gait in stroke patients with hemiplegia.

Zusammenfassung

Ziel der aktuellen Studie war es, die Auswirkungen von Ganzkörper-Vibrationen (whole body vibration WBV) in Kombination mit aufgabenorientiertem Training auf Muskelkraft, Gleichgewicht und Gang bei Schlaganfallpatienten mit Hemiparese zu untersuchen. Insgesamt wurden 24 Schlaganfallpatienten in diese Studie eingeschlossen. Alle Teilnehmer wurden zufällig entweder der Gruppe „Ganzkörper-Vibration kombiniert mit aufgabenorientiertem Training“ (WBVMT; n=12) oder der Gruppe „Ganzkörper-Vibration“ (WBV; n=12) zugeordnet. Die WBVMT-Gruppe erhielt 30 min pro Tag ein Training zu je 8 Sätzen, 5 Mal pro Woche über 4 Wochen. Die WBV-Gruppe trainierte in dieser Zeit parallel 4 Wochen lang 5 Mal pro Woche 30 min pro Tag je 8 Sätze. Beide Gruppen erhielten eine Standard-Rehabilitationsphysiotherapie, jeweils 60 min pro Tag, 5 Mal pro Woche über 4 Wochen. Bei allen Teilnehmern wurden vor und nach der Intervention die Werte für die Muskelkraft des Hüftstreckers (HE) und des Kniestreckers (KE), der 5x Sit-to-Stand-Test (FTSTS), die Stabilitätsgrenze (LOS), der Timed-Up-and-Go-Test (TUG), die Berg-Balance-Skala (BBS), der 10-Meter-Gehtest (10MWT) und der 6-Min-Gehtest (6MWT) ausgewertet. Die WBVMT- und WBV-Gruppen zeigten beide einen signifikanten Anstieg der Werte für HE- und KE-Stärke, FTSTS-Test, LOS, TUG-Test, BBS, 10MWT und 6MWT (S.<0,05). Die WBVMT-Gruppe zeigte jedoch eine signifikant stärkere Verbesserung als die WBV-Gruppe in Bezug auf KE-Muskelkraft und TUG-Test, BBS, 10MWT und 6MWT (S.<0,05). [...]. WBVMT verbesserte die Muskelkraft, das Gleichgewicht und den Gang bei Schlaganfallpatienten mit Hemiplegie.
