Zie hier onder een prachtig onderzoek. Wanneer je voor je gevoel een stijve rug hebt, is je rug dan ook echt stijf? Conclusie: nee.
Here you see a picture of Tasha Stanton testing spinal stiffness in the lab! :)
She did a study, together with e.g. Lorimer Moseley with the question: Does feeling back stiffness actually reflect having a stiff back?
Short conclusion:
No. :)

Conclusion from the article:
"Here we show that a conscious experience of feeling stiff does not reflect true biomechanical back stiffness, but may rather represent a protective perceptual inference that may serve to reduce movement and re-injury.
By showing that feelings of stiffness do not relate to biomechanical stiffness measures and that biomechanical meas-ures of stiffness do not differ between those with and without feelings of stiffness, this suggests that information other than actual joint stiffness is influencing this perceptual inference. Although preliminary, our assertion that this interference is protective is substantiated by the heightened response to applied force in people with back pain and stiffness – they overestimate applied force magnitude but are more sensitive to detecting change.
Last, synchronising auditory information in a way that conveys meaning to pressure applied to the back, modulates these protective responses in a specific manner dependent on the nature of the auditory information, and cru-cially, does so in the absence of changes to biomechanical properties of the spine. Future work is warranted to determine if this protective perceptual inference relates to protective behavioural responses (e.g., movement avoidance)."
She will talk more about her study and more during an interview Karen Litzy will have on September 17th, live on Trust me, I'm a Physiotherapist! :)
