ABOVE: Calcium channels, labeled green in sections of the mouse spinal cord, are blocked by nimodipine, which eases muscle spasms following injury.

People with spinal cord injuries often develop muscle spasms that are difficult to treat. After looking into the mechanisms of this post-injury spasticity in mice, the authors of a paper published on April 15 in Science Translational Medicine determined that calcium channels in the spinal cord seem to play a role.
A six-week course of nimodipine, a calcium channel blocker approved to treat brain hemorrhage, administered immediately after mice sustained injuries to their spinal cords prevented muscle spasms. The effects remained even after the treatment ended, suggesting that inhibiting calcium channels may offer a potential way to alleviate one debilitating consequence of spinal cord injuries.
