- Central symtpoms are often mediated by kinesiophobia, or fear of movement, secondary gain issues (as seen with positive Waddel’s signs). This may be do to severe pain or often associated with fear that is mediated by past pain.This may also be mediated by conditions such as as traumatic brain injury, spinal cord injury, phantom limb pain, and complex regional pain syndrome lead to neuropathic pain and may have a component of centrally mediated symptoms.
- Additionally, there may be a disruption of osteokinematics or tissue lengthening secondary to centrally mediated protective mechanisms.
- Some studies have shown that spinal ROM and even a SLR can be improved by simply helping the patient understand their symptoms to reduce the fear of movement.
