Anti-spasticity splints are typically based on which aspect?

Anti-spasticity splints work by positioning the hand to counteract abnormal muscle tone and keep the hand in a stable, functional alignment. A base on the volar (palm) surface or along the ulnar side provides the most stable support for the palm and the ulnar border, helping to hold the fingers and thumb in a more extended, functional position and reducing the pull of flexor spasticity. This configuration supports the wrist in neutral to slight extension and allows the digits to rest rather than collapse into a clenched position, which is essential for improving function. A dorsal base would place the splint on the back of the hand, offering less support for the palm where spastic patterns tend to compress the hand. A radial base lacks the ulnar-side stability that helps prevent unwanted finger collapse, and a thumb-based splint focuses on the thumb alone rather than addressing the overall hand spastic pattern.
