Comparative Analysis of Lightweight Wheelchairs: Survival Rates Across Studies

This study presents a comparison of survival rates for lightweight folding and ultralight rigid wheelchairs based on ANSI/RESNA minimum equivalent cycles. The study includes LWFW II, LWFW I, AUFW, TURW, and AURW. Findings offer insights into wheelchair durability.

  1. Figure 11. Kaplan-Meier plot of equivalent cycles for current lightweight folding wheelchairs study (LWFW II) and four previous studies: lightweight folding wheelchairs I (LWFW I) [12], aluminum ultra-light folding wheelchairs (AUFW) [13], titanium ultralight rigid wheelchairs (TURW) [14], and aluminum ultralight rigid wheel-chairs (AURW) [15]. Note: Labels and leader lines show cumu-lative survival for each study at American National Standards Institute/Rehabilitation Engineering Society of North America (ANSI/RESNA) minimum equivalent cycles value.
