Effects of whole body vibration training on cardiorespiratory fitness and quality of life in patients with subacute stroke:A randomized controlled trial

Background Cardiorespiratory fitness reduction is potentially related to function/structure,and activity of the stroke patients may be associated with increased risk of cardiovascular disease. Whole body vibration(WBV)training is an efficient alternative therapy for neurological conditions. However,no study has investigated the effects of WBV training on cardiorespiratory fitness in patients with subacute stroke. This single-blinded randomized controlled trial was conducted to assess the effects WBV training on cardiorespiratory fitness and quality of life in individuals with subacute stroke. Methods Thirty-three people with subacute stroke(66.56±5.25 years)were enrolled from 87 patients initially screened(25 patients were excluded by inclusion/exclusion criteria,13 patients for other reasons,16 patients declined participation). Participants were randomly assigned to the low-intensity WBV group(LWBV),high-intensity WBV group(HWBV)and a control group(No WBV).All participants of low-and high-intensity WBV group were exercised on a vibration platform,and the control group performed the same exercise without WBV. Outcome measurements included oxygen uptake(VO_2)rate and walking distance during the 6-Minute Walk Test(6 MWT),and quality of life(Short-Form 12 Health Survey,SF-12). The measurements were performed by a researcher at baseline and immediately after the 8-week WBV intervention period. Results Statistical analysis revealed a significant time effect for VO_2 rate and walking distance achieved during 6 MWT,and the SF-12 physical composite score domain in all three groups after the 8-week treatment period(P0.05). However,the effects of time by group interactions were not significant for any of the VO_2 and walking distance during 6 MWT,and quality of life(P0.05). Conclusions The addition of the 8-week WBV program to the leg exercise protocol is not more effective in enhancing cardiorespiratory fitness and quality of life than leg exercises alone in subacute stroke patients with mild to moderate motor impairments.[S Chin J Cardiol 2019;20(3):131-140]     

下肢步行机器人用于C-D级脊髓损伤患者步行训练的疗效研究

正脊髓损伤后主要功能缺陷是步行功能障碍~([1]),因此,步行功能恢复是脊髓损伤患者康复的重要方面,特别是C-D级脊髓损伤患者,由于这类患者大部分双下肢均残存有部分肌肉力量,但常因肌力不足、肌痉挛等因素的影响,导致无法步行或步态的异常。在目前的康复治疗中,主要是通过给予肌力训练、牵伸训练、站立训练、平衡训练等一系列治疗后,患者功能条件允许,才进行步行、步态训练。为了寻找更好的训练方法,部分有条件的医院,会运用运动平板训练。但是,由
