截肢后,许多人变得不那么活跃,感到孤独和失去独立。了解与低体力活动水平和参与度相关的因素可能有助于定义关键干预措施,这些干预措施可以支持假肢使用者,使他们能够过上更加活跃和融入社会的生活方式。这项纵向观察研究旨在评估身体活动之间的关系,社区参与,假肢配合,使用动态测量法的舒适度和用户满意度,在柬埔寨建立的下肢假肢使用者队列中进行3D扫描和问卷调查。
20名参与者(5F:15M,九经股,十一个经胫骨,招募24-60岁和截肢后3-43岁)。他们完成了一份问卷,其中包括他们的人口统计数据,社区参与,在研究开始时,假肢的满意度和舒适度,三至六个月后。在研究开始和结束时,对他们的假肢接受腔和残肢进行了3D扫描。加速度计嵌入在假肢的小腿上,收集十周的活动数据。
参与者平均每天4470步(743-7315步/天),大部分醒着的时间都戴着假肢,平均13.4小时/天(4.5-17.6小时/天)。活动和磨损小时数的自我报告测量值与这些加速度计数据相关(分别为Spearman的rho=0.59和rs=0.71)。更活跃的参与者每天佩戴假体的时间更长(Pearsonr=0.73),并且对承窝配合更满意(rs=0.49)。较长的残肢与更好的社区参与(rs=0.56)和舒适度(rs=0.56)相关。自我报告的社区参与与一个人的活动水平无关(rs=0.13),或他们的假体舒适度(rs=0.19),活动对个人的重要性之间只有微弱的相关性,以及他们参与的频率(rs=0.37)。总体舒适度的简单0-10量表没有提供足够的细节来了解所经历的不适的类型和严重程度。
在确定下肢截肢的人群中,感知和测量的活动水平之间的关联与插座满意度相关。样本量小意味着这些相关性应该谨慎解释,但它们表明了值得进一步研究的变量,以了解柬埔寨假肢使用者社区参与和体育活动的障碍,以及可能在其他设置中。
After amputation, many people become less active, feel lonely and lose independence. Understanding the factors associated with low physical activity levels and participation could contribute to defining key interventions which can support prosthesis users so they can live a more active and socially included lifestyle. This longitudinal observational study aims to assess relationships between physical activity, community participation, prosthetic fit, comfort and user satisfaction using actimetry, 3D scans and questionnaires in a Cambodian cohort of established lower limb prosthesis users.
Twenty participants (5F:15M, nine transfemoral, eleven transtibial, 24-60 years old and 3-43 years since amputation) were recruited. They completed a questionnaire which included their demographics, community participation, prosthesis satisfaction and comfort at the start of the study, and between three and six months later. Their prosthetic sockets and residual limbs were 3D scanned at the start and end of the study. Accelerometers were embedded under the cosmesis on the shank of the prosthesis, to collect ten weeks of activity data.
Participants averaged 4470 steps/day (743-7315 steps/day), and wore their prosthesis for most waking hours, averaging 13.4 h/day (4.5-17.6 h/day). Self-reported measures of activity and hours of wear correlated with these accelerometer data (Spearman\'s rho rs = 0.59, and rs = 0.71, respectively). Participants who were more active wore their prosthesis for more hours/day (Pearson r = 0.73) and were more satisfied with socket fit (rs = 0.49). A longer residual limb correlated with better community participation (rs = 0.56) and comfort (rs = 0.56). Self-reported community participation did not correlate with a person\'s activity level (rs = 0.13), or their prosthesis comfort (rs = 0.19), and there was only weak correlation between how important the activity was to an individual, and how often they participated in it (rs = 0.37). A simple 0-10 scale of overall comfort did not provide enough detail to understand the types and severity of discomfort experienced.
Associations between perceived and measured activity levels correlated with socket satisfaction in this cohort of people with established lower limb amputations. The small sample size means these correlations should be interpreted with caution, but they indicate variables worthy of further study to understand barriers to community engagement and physical activity for prosthesis users in Cambodia, and potentially in other settings.
