Hemiplegia recovers after cranioplasty in stroke patients in the chronic stage.

ABSTRACT

We evaluated quantitatively the recovery from impairment and disability in hemiplegic stroke survivors who received cranioplasty in the chronic stage. Seven first-ever stroke survivors with hemiplegia (mean age 56+/-3 years) who required delayed (3-9 months after the onset) cranioplasty during continuous rehabilitation therapy were studied. Recovery grade (1-12) of hemiplegia and Barthel index were assessed monthly before (the first rehabilitation) and after the cranioplasty (the second rehabilitation). The recovery grade of upper and lower extremity movements significantly increased both in the first and in the second rehabilitation. Changes in the upper and lower extremity grades were significantly larger in the second rehabilitation (1.0+/-0.3 in the first vs. 2.4+/-0.7 in the second rehabilitation for upper extremity, P=0.007; 1.4+/-0.4 in the first vs. 3.4+/-0.7 in the second rehabilitation for lower extremity, P=0.002). Increase in the Barthel index was larger in the second rehabilitation (23+/-8 in the first vs. 33+/-5 in the second rehabilitation); all patients regained the ability to walk. Significant recovery of functional grade and recovery from disability occurred after the cranioplasty in the chronic stage (>or=3 months) of stroke.
