Physiotherapy Coupled With Dextroamphetamine for Rehabilitation After Hemiparetic Stroke: A Randomized, Double-Blind, Placebo-Controlled Trial
Background and Purpose — Hemiparesis is the commonest disabling deficit caused by stroke . In animals , dextroamphetamine ( AMPH ) paired with training enhances motor recovery , but its clinical efficacy is uncertain . Methods — In a r and omized , double-blind , placebo-controlled trial , 71 stroke patients were stratified by hemiparesis severity and r and omly assigned to 10 sessions of physiotherapy coupled with either 10 mg AMPH or placebo . Study treatments were administered by 1 physiotherapist , beginning 5 to 10 days after stroke and continuing twice per week for 5 weeks . Outcomes were assessed by 1 physiotherapist at baseline , after each treatment session , at 6 weeks , and at 3 months . The primary outcome was motor recovery ( impairment level ) on the Fugl-Meyer ( FM ) scale . Secondary outcomes assessed mobility , ambulation , arm/h and function , and independence in activities of daily living . Results — Baseline hemiparesis was severe overall ( mean FM score 27.7±20.0 ) . Motor scores improved during treatment in both groups ( mean change , baseline to 3 months 29.5±16.6 ) . Repeated- measures ANOVA revealed no significant differences in recovery between the treatment groups for the entire cohort ( n=67 ) or for subgroups with a severe hemiparesis ( n=43 ) , moderate hemiparesis ( n=24 ) , or cortically based stroke ( n=26 ) . In the moderate subgroup , there was a significant drug × time interaction for upper extremity motor recovery ( F=5.14 ; P<0.001 ) , although there was a significant baseline imbalance in motor scores in this subgroup . Conclusion — In stroke patients with a severe motor deficit , 10 mg AMPH coupled with physiotherapy twice per week for 5 weeks in the early poststroke period provided no additional benefit in motor or functional recovery compared with physiotherapy alone . Patients with moderate severity hemiparesis deserve further investigation . Increased intensity and longer duration drug/therapy dosing regimens should be explored , targeting the upper and lower limbs separately
