Key result
Spinal cord compression using a 70 g aneurysm clip for 60 seconds significantly reduced BBB locomotor scores at 28 days compared to laminectomy alone (mean rank 2.50 vs 6.50, p=0.019).
Why the study?
Spinal cord injuries have dire pathological consequences, prompting the development and testing of a standardized animal compression injury model to examine behaviors in rodents.
Does a standardized spinal cord compression injury model using a 70 gm aneurysm clip for 60 seconds affect sensory-motor abilities in mature Sprague Dawley rats compared to laminectomy alone?

The study describes a standardized spinal cord compression injury model in rats to evaluate sensory-motor abilities.
Provides standardized rat SCI model for sensory-motor testing; leaves open human translation pending further validation.
Spinal cord injuries (SCI) are often associated with dire consequences resulting in the serious pathological conditions in SCI patients. These consequences have resulted in an increased interest of basic science researchers and healthcare professionals to investigate effective treatment of SCI. Among these initiatives, animal experimentation models emerged as a successful tool to study the SCI in detail. We created a standardized spinal cord compression injury model for this research and tested its effectiveness in examining the behaviors of rodents with SCI. We used 24 mature Sprague Dawley rats, weighing between 250 and 320g. Two sets, A and B, of rats were created. Under general anesthesia, Rat from group A underwent laminectomy and only had the T6–T8 vertebrae of their spinal arch removed. in contrast to the rats in group B underwent laminectomy as well as compression injuries using an aneurysm clip of 70 gm for 60 seconds. All the rats were observed at day 7, 14 and 28 following the experimentation. Using standardised techniques, the sensory-motor abilities were evaluated.

Khan et al. (2023) studied Spinal cord injury (n=24). Spinal cord compression using aneurysm clip vs. Laminectomy without compression was evaluated on Basso, Beattie, Bresnahan (BBB) locomotor score at 28 days (p=0.019). Spinal cord compression using a 70 g aneurysm clip for 60 seconds significantly reduced BBB locomotor scores at 28 days compared to laminectomy alone (mean rank 2.50 vs 6.50, p=0.019).
