Still going, huh?
I thought of this thread when I came across a link (provided) with the following recommendation in it,
"Officers should avoid placing hard objects (typically handcuffs) on the lumbar spine. In case of a fall, the spine could be injured severely by the handcuffs or similar objects. They also could create back pain from constant pressure on the lower back while sitting in a car. It is recommended that a soft pouch (eg, containing latex gloves) be placed over the lumbar spine."

Anyway, this thread made me remember a piece of equipment I bought a few years ago. It was a custom ASP holster which was designed to carry an ASP SOB in plainclothes work, with the handle angled and positioned for rapid draw and extension. At the end of the first day my lower back was pretty tender (riding around in the car, getting in & out). After the second day, and trying to move the SOB ASP holster within the limits permitted by my weapon holster, my lower back was downright painful. I couldn't find a way to wear it that didn't cause me pain. Glad I didn't fall down while wearing it.
You know, if you browse among some other forums and threads you can occasionally come across a reference where someone claims that a SOB holster is actually like wearing a back brace.
Lots of folks have opinions.
I'd imagine that someone in the health care field would have the ability to ask other health care providers about subjects such as this, as well as insurance companies, risk management & worker's comp folks.
Me? I don't use SOB holsters, or wear other gear SOB, because I find it uncomfortable at best, and more often downright painful ... and I leave it at that. I've had work-related back (and other) injuries, and I've come to appreciate taking reasonable steps to try and minimize my excessive exposure to further injuries.
Not everyone agrees on some subjects, you know ...
