I'm teaching a freshman seminar course this year at Texas State. It's about introducing students to the university as well as the college learning environment and culture. I was prepping them for some interview and presentation assignments and stumbled across a fine TED Talk by Amy Cuddy
about the importance of body language.
The information in this is fascinating. Basically, you can see significant, measurable changes in hormones simply by maintaining a posture for as little as two minutes. It doesn't seem to matter if you actually feel powerful or weak, but if you hold the power poses, you increase testosterone and decrease cortisol. It also seems that subjects are better able to cope with stress and have superior results in job interviews following this 2-minute posture hold.
If the simple act of assuming a posture can alter the brain, I wonder if having patients in chronic pain can see a similar benefit. Power poses before therapy might just help take that edge off and allow more pain-free motion during a therapy session. Of course, this is just me postulating, but I wonder... Testosterone might not have an obvious connection
to pain, but cortisol and resultant stress levels certainly could. Perhaps testosterone could somehow enhance self-efficacy, which is important for function in the face of chronic pain
