Electric powered wheelchairs (EPWs) are an important form of mobility for many persons with disabilities. Previous devices have been successful at measuring usage of EPW, but they have been limited by size or technical issues. In this study improvements were made to a caster data logger for EPWs and were used to collect pilot EPW usage data during and after the National Veterans’ Wheelchair Games (NVWG). Subjects who used an EPW as their primary means of mobility were recruited at the NVWG for this study. In 5 days at the games the participants (n=5) traveled a distance of 7751 ± 3439m per day, while traveling 3397±1300 m (n = 4) per day during 5 days the following week. The CDLs performed well and with improvement could become a valuable usage measuring tool. The data set is of limited sample size; however, future work could correct this and provide insight into barriers to EPW usage.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
