目的：为临床医生和轮椅使用者提供数据，以比较四种不同超轻型轮椅型号的耐用性、强度、稳定性和成本效益，并将本研究的结果与已发表的轻型轮椅的研究结果进行比较。设计：对不同制造商的四种轮椅型号（总共 12 种轮椅）进行标准测试和成本效益分析。结果：超轻型之间的疲劳寿命和价值（每美元等效周期）存在显着差异（p 小于或等于 0.05）轮椅经过测试。对于最不稳定和最稳定的配置，后向稳定性倾斜角度也存在显着差异（p 小于或等于 0.05）。向前和横向稳定性没有差异。超轻型轮椅（1,009,108 次循环）的疲劳寿命显着（p 小于或等于 0.05）高于之前报道的轻型轮椅（187,370 次循环）。轻型轮椅的平均价格为每美元 210 次循环，而超轻型轮椅每美元平均为 673 次循环。轻型和超轻型轮椅的疲劳寿命值差异有统计学意义（p小于或等于0.05）。结论：测试的四种超轻型手动轮椅型号的疲劳寿命和值存在差异。这表明超轻型手动轮椅的质量并不完全相同。超轻手动轮椅的疲劳寿命和价值明显高于之前报道的远轻手动轮椅。这表明超轻型轮椅的质量可能比轻型手动轮椅更高。临床医生和消费者应认真考虑选择超轻手动轮椅来满足他们的轮椅移动需求。(C) 1999 年，由美国康复医学会和美国物理医学与康复学会提出。
Objectives: To provide data for clinicians and wheelchair users to compare the durability, strength, stability, and cost effectiveness of four different ultralight wheelchair models, and to compare the results of this study with those published for lightweight wheelchairs.Design: Standards testing and cost-effectiveness analysis of four wheelchair models from different manufacturers (12 wheelchairs total).Results: There were significant differences (p less than or equal to .05) in the fatigue life and value (equivalent cycles per dollar) among the ultralight wheelchairs tested. There was also a significant difference (p less than or equal to.05) in rearward stability tilt angle for the least and most stable configurations. There were no differences in forward and lateral stability. The ultralight wheelchairs (1,009,108 cycles) had significantly (p less than or equal to .05) higher fatigue lives than previously reported for lightweight wheelchairs (187,370 cycles). The lightweight wheelchairs had a mean value of 210 cycles per dollar compared to 673 cycles per dollar for the ultralight wheelchairs. The difference in value for the lightweight and ultralight wheelchairs was statistically significant (p less than or equal to .05).Conclusion: There were differences in the fatigue life and value among the four models of ultralight manual wheelchairs tested. This indicates that ultralight manual wheelchairs are not all of equal quality. The fatigue life and value of the ultralight manual wheelchairs were significantly higher than those previously reported far lightweight manual wheelchairs. This indicates that ultralight wheelchairs may be of higher quality than lightweight manual wheelchairs. Clinicians and consumers should seriously consider selecting an ultralight manual wheelchair to meet their wheelchair mobility needs.(C) 1999 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.
