Vacuum-assisted suspension systems provide better suspension than non-vacuum systems, but data are limited on whether they improve physical activity levels and quality of life for people with amputation.
To compare the physical activity and quality of life levels of people with transtibial amputation using PIN/LOCK suspension system or vacuum-assisted suspension systems with those of able-bodied controls and to investigate parameters associated with physical activity levels.
A cross-sectional observational study.
Fifty-one people with amputation and 51 controls participated. The International Physical Activity Questionnaire Short Form and Short Form 36 were used to measure the physical activity and quality of life, respectively.
The total physical activity and Short Form 36 scores were significantly lower in the participants with amputation than the controls. There were no significant differences between the two types of suspension systems in terms of physical activity levels and quality of life. The vacuum-assisted suspension system users reported significantly more bodily pain on the Short Form 36 questionnaire than the controls ( = 0.003). The only parameter that correlated significantly with the total physical activity was the Short Form 36 physical functioning subscale ( = 0.302, = 0.031).
Contrary to our expectations, vacuum-assisted suspension system users compared to PIN/LOCK users did not report greater levels of physical activity or improved quality of life or levels closer to comparable controls.
A better understanding of the effects of different prosthetic suspension systems on physical activity and quality of life may help clinicians when prescribing prostheses, as well as setting appropriate prosthetic expectations. This study suggests that vacuum-assisted suspension systems and PIN/LOCK suspension systems provide equal benefit to users with regards to physical activity and quality of life.
真空辅助悬吊系统比非真空系统提供更好的悬吊效果，但关于它们是否能提高截肢者的身体活动水平和生活质量的数据有限。
比较使用PIN/LOCK悬吊系统或真空辅助悬吊系统的胫部截肢者与健全对照者的身体活动和生活质量水平，并研究与身体活动水平相关的参数。
一项横断面观察性研究。
51名截肢者和51名对照者参与研究。分别使用国际体力活动问卷简表和健康调查简表36来测量身体活动和生活质量。
截肢参与者的总身体活动量和健康调查简表36得分显著低于对照者。两种悬吊系统在身体活动水平和生活质量方面没有显著差异。真空辅助悬吊系统使用者在健康调查简表36问卷上报告的身体疼痛明显多于对照者（P = 0.003）。与总身体活动量显著相关的唯一参数是健康调查简表36的身体功能分量表（P = 0.302，P = 0.031）。
与我们的预期相反，与PIN/LOCK使用者相比，真空辅助悬吊系统使用者并未报告更高水平的身体活动或改善的生活质量，或更接近可比对照者的水平。
更好地了解不同假肢悬吊系统对身体活动和生活质量的影响，可能有助于临床医生在开具假肢处方以及设定适当的假肢期望时提供帮助。这项研究表明，在身体活动和生活质量方面，真空辅助悬吊系统和PIN/LOCK悬吊系统为使用者提供了同等的益处。
