Pre-post design; before and after vibration intervention.
To explore effect of a focal, self-applied upper extremity (UE) vibration intervention on UE spasticity for individuals with tetraplegia. The secondary objectives were to explore the acceptability and ease of use of this intervention.
Specialty rehabilitation center in Georgia, USA.
Eleven participants each completed one session of focal, self-applied vibration to the UEs. UE spasticity was measured using the Modified Ashworth Scale (MAS). UE function was measured using the Box & Block (B&B) test which measures the effectiveness of grasp, transport, and release. These measurements were taken pre-intervention, immediately post-intervention, and 20 min post-intervention. Participants also self-reported the acceptability and usability of the intervention, their perception of change in their spasticity and completed the Qualities of Spasticity Questionnaire.
In the full group analysis of the spasticity measures, no significant effects were found. Subgroup analysis, however, indicated participants with higher spasticity demonstrated significantly more change on the MAS than the lower spasticity group. Analysis did not reveal any impact of the intervention on UE function as measured by the B&B. Ten out of eleven participants indicated that they agreed or strongly agreed that the intervention would be valuable to have at home.
Participants with higher spasticity demonstrated decreased spasticity after focal UE vibration, although there was no clear effect on grasp, transport and release function. Participants were satisfied with the intervention; most were able to use it independently and indicated it would be a valuable home intervention.
前后对照设计；振动干预前后。
探讨针对四肢瘫痪患者的局部、自我施加的上肢振动干预对上肢痉挛的影响。次要目的是探讨该干预措施的可接受性和易用性。
美国佐治亚州的专业康复中心。
11名参与者每人完成了一次针对上肢的局部、自我施加振动治疗。使用改良Ashworth量表（MAS）测量上肢痉挛程度。使用箱块测试（B&B）测量上肢功能，该测试衡量抓握、搬运和释放的有效性。这些测量在干预前、干预后立即以及干预后20分钟进行。参与者还自我报告了干预措施的可接受性和可用性、他们对痉挛变化的感知，并完成了痉挛质量问卷。
在对痉挛测量的全组分析中，未发现显著效果。然而，亚组分析表明，痉挛程度较高的参与者在MAS上的变化明显大于痉挛程度较低的组。分析未发现干预对B&B测量的上肢功能有任何影响。11名参与者中有10名表示他们同意或强烈同意该干预措施在家中会很有价值。
痉挛程度较高的参与者在局部上肢振动后痉挛程度降低，尽管对抓握、搬运和释放功能没有明显影响。参与者对该干预措施感到满意；大多数人能够独立使用它，并表示这将是一种有价值的家庭干预措施。
