T1 rhizotomy for post-stroke hand flexion spasticity: a preliminary report of 15 cases

1

T1 rhizotomy is proposed as a novel surgical intervention for managing hand flexion spasticity in post-stroke patients.
2

Fifteen patients underwent T1 rhizotomy, showing significant reductions in spasticity and improvements in hand function after one year.
3

The mean Modified Ashworth Scale score decreased from 3.07 to 1.20, indicating a substantial reduction in spasticity.
4

Functional outcomes improved significantly, with the mean QuickDASH score decreasing from 52.47 to 34.00 and the Barthel Index increasing from 66.73 to 83.00.
5

T1 rhizotomy demonstrated safety with no major complications, suggesting it may be an effective option for post-stroke hand spasticity.
