Lower extremity prostheses outcomes are not known in US veterans population. In this study, 46 veterans aged 18-80 years with lower extremity amputation completed the MOTIVATe questionnaire. Demographics, mobility device characteristics, functional performance, and device satisfaction were compared between Prosthetics and Wheelchair Group. Wheelchair Group, were older veterans with more comorbidity, higher levels of bilateral vascular amputations, and significantly more likely to have an SCI (p=0.005), compared to prostheses group. Both groups reported significant use of wheelchairs, with the Wheelchair Group using a greater number of other mobility devices. Prostheses use with ease and level of activities were negatively correlated, with significant association between use and activities like ‘in and out of car/bus’ (p=0.04) and ‘sports activities’ (p=0.009). A difference in the satisfaction levels between the two groups was not consistent. Determining long-term outcomes is critical to prosthetics rehabilitation, to maximize prostheses use and abandonment prevention.

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.
