A biomechanical analysis of coitus
October 23, 2014 1:22 PM Subscribe
Objective: To describe male spine movement and posture characteristics during coitus and compare these characteristics across 5 common coital positions. Results: Based on range of motion, the least-to-most recommended positions for a male flexion-intolerant patient are mSIDE, mMISS2, mQUAD2, mMISS1, and mQUAD1 (NSFW).
Lambada, the 403 of love! Or something.

I would think some variation of the cowgirl would be best for male LBP.

Is it me, or is "quadruped" the least sexiest-sounding sexual position ever?

I've always loved the idea of bad back jack as a excuse against premature ejaculation - medical conditions suck - I meant no offense.

Sorry for the 403. It is just a direct link to the Figure 4 that shows the different positions.

Two variations of QUADRUPED were included in this study: one in which the female is supporting her upper body with her elbows (mQUAD1) and the other with her hands (mQUAD2).
The clinical descriptors are enough to make my back hurt, too.

A couple of excerpts:
posted by Michele in California at 2:22 PM on October 23, 2014
Approximately 34%1 to 84%2 of males with LBP have reported a decrease in the frequency of coitus. Sexual activity is a known indicator of quality of life3 and is recognized as an integral measure of health and disability;This is super interesting to me. I don't have any notable back problems (and am not male), though my ex husband did (and he's male). It would be great to see more actual serious scientific studies on how to effectively accommodate various disabilities during coitus. I have serious respiratory problems, so I am not a fan of missionary: The last thing I want while already breathing hard is some man's weight on my chest. There are times when that can actually put me into respiratory distress, where I begin gasping and wheezing. Not exactly sexy fun times, that.
It is interesting to note that a seemingly subtle change in posture—for example, the male supporting his upper body with his elbows (mMISS2) or his hands (mMISS1) during different variations of MISSIONARY—altered the spine kinematic profile significantly;

Okay so seriously with the SCIENCE, can someone explain why MQUAD2 is less desirable than mQUAD4? They seems largely similar. I mean, it's possible I've been fucking wrong my whole life or something, but I can't see how the motion or positioning are significantly different.

I don't know if you have been fucking wrong your whole life, but you may be typing wrong. I don't see an mQUAD4 listed. So that kind of makes it hard to answer this with SCIENCE, since I can't find the data to which you refer.
Though I have terrible eyesight, so maybe I am just seeing wrong.

Canadian Chiropractor summarized this study in their article on "when sex is a pain in the back":
Overall, the study found both men and women employ a lot of spinal motion during sex, said Sidorkewicz. “In general, to make any position more spine-sparing, we're recommending that the individual who's controlling the movement use more of their hips and knees, rather than their spine,” while their partner keeps a more neutral supine position.posted by heatherann at 5:35 PM on October 23, 2014
Ah crap. I spent all those years looking for someone to help me with the Spinning Basket position. Nobody cares.
Well, I was always sort of fond of the elbows and knees posture--me on top, mostly. That way my partner gets to do some creative wiggling, and we could take turns spanking the pony.
Thanks for the link. I've dragged out a whole set of memories to enjoy in my dotage.

For a traditional production, you should make initial contact with the flying company at least ten weeks in advance of your installation dates or twelve weeks in advance of your opening date. Plan to have an agreement in place at least five weeks before you expect to see equipment arrive at your door. If your production is in the six week period leading up to Easter or Christmas (the busiest times for flying effects) or if you are mounting a production that may require a special flying system, it is best to add a few weeks to that.

Documenting female spine motion during coitus with a commentary on the implications for the low back pain patient (unfortunately paywalled), a follow-up study by the same authors, this time with a focus on female low back pain.The least-to-most recommended positions for a female flexion-intolerant patient are: fMISS2, fMISS1, fQUAD1, fSIDE, and fQUAD2.
