Feelings of stiffness in your low back are often cause for concern, and they can indicate a burgeoning problem that may require medical attention. But what if it’s all in your head? Of course, it is insulting and a bit denigrating when someone implies that your feelings of back stiffness are not real. Yet new research has unearthed some interesting findings about the relationship between feelings of stiffness and objective measures of actual mechanical stiffness.
Stiffness itself is a vague term that alludes to increased muscle tone and perceptions of force. Stiffness is often described as perceived resistance to movement, but some studies suggest that stiffness is a learned construct that may reflect fear of movement, especially in cases where a patient has previously experienced injury and pain, and therefore restricts their own movement as a protective mechanism.
In a recent study, researchers set out to explore the relationship between perceptions of back stiffness and objective measure of the same. They hypothesized that, “feelings of back stiffness are a protective perceptual construct, rather than reflecting biomechanical properties of the back.”
The study consisted of three experiments that sought to demonstrate that feelings of stiffness are unrelated to objective measures of spinal stiffness, and furthermore, that there is no difference in objective measures between participants who reported feeling stiff and those who did not. They also wanted to see if perceptions of stiffness were multi-sensory in nature.
In the study, 15 individuals reporting chronic low back pain accompanied by feelings of stiffness were matched by age and gender to a control group of 15 healthy people who did not have low back pain or feelings of stiffness.
The findings of this study suggest that perceptions of low back pain and stiffness do not necessarily correlate with objective measure of stiffness, and that perceived stiffness may be a protective mechanism to avoid pain and injury.
People who report feeling back pain and stiffness often over-estimate applied forces and are adept at detecting changes in applied force. When sound was added to applied pressure, it modulated the perception of pressure, suggesting that feelings of stiffness are multisensory, and may serve to protect the body from pain and injury.
The study’s outcomes may be helpful to healthcare providers when diagnosing patients who present with back pain and stiffness. Perceptions are by nature subjective, and may not necessarily correlate with actual structural damage. Hence, modes of evaluating patients that do not place undue emphasis on perceptions of pain and stiffness may be more useful in accurately assessing a patient’s needs.

and a faulty diagnosis can make treatment a total waste of time.
Failure to accurately diagnose a condition in its early stages can lead
to chronic problems and sometimes devastating results.
Diagnostic musculoskeletal sonography (MSUS) provides the perfect tool for the rehab practitioner. Yet many doctors and physical therapists have no experience with MSUS, are unaware of its advantages, and have no idea how to use it as a diagnostic tool.
Below is a prime example of how ultrasound can take the guesswork out of diagnosis.Successful Treatment
A bad physical therapy experience is one of the primary causes of unnecessary surgery.
We have equipped our clinic with the latest research-grade technology to arrive at objective and accurate diagnoses, and to objectively measure our patients’ progress.
Most importantly, we are the only facility in the US where structural medical diagnosis is reflected in functional treatment, and vice versa.
In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.
Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.
The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
