Abstract:

Objective To explore the effects of different frequencies of whole body vibration training on the balance and walking function of stroke patients. Methods A total of 60 hospitalized stroke patients from January 2018 to June 2019 were included and randomly divided into 15 Hz group（n = 30）and 30 Hz group（n = 30）. Both groups received routine rehabilitation training. Additionally ，the 15 Hz group received 15 Hz whole body vibration training and the 30 Hz group received 30 Hz whole body vibration training for 6 weeks. Before and after training，the berg balance scale（BBS）was used to assess the patient′s balance function，and the weight⁃bearing time，step length，pace，and functional ambulation category（FAC）were used to assess the patient′s walking function. Results The BBS scores of the two groups after training were significantly higher than those before training（P < 0.05），and the 30Hz group was significantly better than the 15 Hz group（P < 0.05）. The weight⁃ bearing time，step length，pace，and FAC classification of the two groups after training were significantly increased than before training（P < 0.05），and the 30 Hz group was significantly better than the 15 Hz group（P < 0.05）. Conclusion Both 15 Hz and 30 Hz whole body vibration training can improve the balance and walking function of stroke patients，and the effect pf 30 Hz whole body vibration training is better than that of 15 Hz training.
