Commenting on the work, Gemma Sesmilo, MD, an endocrinologist at University Hospital Dexeus, Barcelona, Spain, urged caution but nevertheless said, "It is encouraging to have a small pilot study showing neuronal improvement in patients with spinal-cord injury. (medscape.com)
And in patients with compete spinal injury, around 80% of those affected are deficient in growth hormone, for reasons that are not clear. (medscape.com)
He stressed that the levels of growth hormone are much lower after spinal injury than following traumatic brain injury. (medscape.com)
The test showed that patients in the growth-hormone group "regained far more feeling below the site of spinal injury after 6 months of treatment compared with the placebo group," reported Dr Cuatrecasas. (medscape.com)
As a person with spinal cord injury (SCI) advances through acute rehabilitation, physical therapy addresses mobility issues. (medscape.com)

A partial severing or even bruising or swelling of the spinal cord results in varying degrees of mixed function and paralysis. (apparelyzed.com)

This occurs because the spinothalamic tract nerves are damaged before they have a chance to cross the midline (figure above). (emcrit.org)

[1] The spinal segments caudal to the dysgenetic segment are always normal. (bioline.org.br)
[1] Embryonic chordamesodermal derangement of an intermediate segment along the longitudinal embryonal axis results in SSD, whereas derangement of the most caudal segment results in CRS. (bioline.org.br)

Building on top of the bony structure, there is also a wide array of ligamentum support for the spinal column. (ironmagazineforums.com)

Conservative secondary interventions are effective at attenuating peripheral nerve inflammation and conduction velocity declines but not sensorimotor declines with high repetition high force task. (cdc.gov)
Aims: We have shown that performance of high repetition tasks with or without force results in peripheral nerve inflammation and decreased conduction velocity (NCV), increased spinal cord neuropeptides, and motor dysfunction. (cdc.gov)
DN was confirmed by sensorimotor disturbance and diminished nerve conduction velocity (NCV). (bvsalud.org)

It's a complex structure of bones, nerves, disks, and spinal fluid that protects the delicate nerve tissue of the spinal cord. (upmc.com)
