Greetings everyone,

I was asked by our University Public Relations dept. if there are
recommendations on the desired design of a snow shovel (the bent shaft
shovel was one mentioned) or whether there are specific ways to avoid back
problems while shoveling snow. I made a suggestion that snow pushers (see
below) should reduce back load by avoiding lifting, but didn't have any
research to back it up. A search of electronic databases produced several
articles regarding cardiac demand and events related to snow shoveling, but
the only ones I could find that remotely addressed their questions are
listed below. Does anyone have any suggestions?

As usual I will post a summary of responses. Thank you.
