Wheelchair research includes both qualitative and quantitative approaches, primarily focuses on functionality and skill performance and is often limited to short testing periods. This is the first study to use the combination of a performance test (i.e. wheelchair propulsion test) and a multiple-day mobility assessment to evaluate wheelchair designs in rural areas of a developing country.
Test the feasibility of using wheel-mounted accelerometers to document bouts of wheeled mobility data in rural settings and use these data to compare how patients respond to different wheelchair designs.
A quasi-experimental, pre- and post-test design was used to test the differences between locally manufactured wheelchairs (push rim and tricycle) and an imported intervention product (dual-lever propulsion wheelchair). A one-way repeated measures analysis of variance was used to interpret propulsion and wheeled mobility data.
There were no statistical differences in bouts of mobility between the locally manufactured and intervention product, which was explained by high amounts of variability within the data. With regard to the propulsion test, push rim users were significantly more efficient when using the intervention product compared with tricycle users.
Use of wheel-mounted accelerometers as a means to test user mobility proved to be a feasible methodology in rural settings. Variability in wheeled mobility data could be decreased with longer acclimatisation periods. The data suggest that push rim users experience an easier transition to a dual-lever propulsion system.
轮椅研究包括定性和定量方法，主要侧重于功能和技能表现，且测试期往往较短。这是第一项结合性能测试（即轮椅推进测试）和多日移动性评估来评估发展中国家农村地区轮椅设计的研究。
测试使用轮式加速度计记录农村环境中轮式移动数据的可行性，并利用这些数据比较患者对不同轮椅设计的反应。
采用准实验性的前后测试设计，以测试本地制造的轮椅（推轮和三轮车）与进口干预产品（双杠杆推进轮椅）之间的差异。使用单向重复测量方差分析来解释推进和轮式移动数据。
本地制造的轮椅和干预产品在移动次数上没有统计学差异，这可以用数据中的高变异性来解释。在推进测试方面，与三轮车使用者相比，推轮使用者在使用干预产品时效率显著更高。
在农村环境中，使用轮式加速度计作为测试用户移动性的方法被证明是可行的。通过更长的适应期可以降低轮式移动数据的变异性。数据表明，推轮使用者更容易过渡到双杠杆推进系统。
