title: Citalopram improves dexterity in chronic stroke patients.
abstract: BACKGROUND
  A majority of stroke patients have persisting motor deficits despite ongoing physiotherapy. Therefore, additional treatment options are desirable.
  
  
  OBJECTIVE
  We investigated if the serotonin reuptake inhibitor, citalopram, would improve motor functions in chronic stroke patients.
  
  
  METHODS
  In all, 8 patients >6 months after their stroke participated in a double-blind, placebo-controlled, single-dose crossover experiment. The order (first drug then placebo or vice versa) was randomized. Sessions were separated by at least 2 weeks. Motor function was assessed by nine-hole peg test, and measurements of hand grip-strength before drug intake, 2 hours after drug intake, and after 1 hour of training aimed at improving the function of the paretic hand.
  
  
  RESULTS
  Compared with placebo, citalopram intake significantly improved performance of the nine-hole peg test for the paretic hand but not for the unaffected hand. Hand grip-strength remained unchanged.
  
  
  CONCLUSIONS
  A single dose of citalopram can enhance dexterity in chronic stroke patients. This pilot study justifies a test of efficacy of citalopram in a larger group of stroke patients.
