BACKGROUND:　Neuro-rehabilitative　training　has　been　shown　to　promote　motor　function　recovery　in　stroke　patients,　although　the　underlying　mechanisms　have　not　been　fully　clarified　OBJECTIVE:　To　investigate　the　effects　of　finger　movement　training　on　functional　connectivity　and　information　flow　direction　in　cerebral　motor　areas　of　healthy　people　using　electroencephalogram　(EEG)　DESIGN,　TIME　AND　SETTING:　A　self-controlled,　observational　study　was　performed　at　the　College　of　Life　Science　and　Bioengineering.　Beijing　University　of　Technology　between　December　2008　and　April　2009　PARTICIPANTS:　Nineteen　healthy　adults,　who　seldom　played　musical　instruments　or　keyboards,　were　included　in　the　present　study　METHODS:　Specific　finger　movement　training　was　performed,　and　all　subjects　were　asked　to　separately　press　keys　with　their　left　or　right　hand　fingers,　according　to　instructions　The　task　comprised　five　sessions　of　test-train-test-train-test　Thirty-six　channel　EEG　signals　were　recorded　in　different　test　sessions　prior　to　and　after　training　Data　were　statistically　analyzed　using　one-way　analysis　of　variance　MAIN　OUTCOME　MEASURES:　The　number　of　effective　performances,　correct　ratio,　average　response　time.　average　movement　time,　correlation　coefficient　between　pairs　of　EEG　channels,　and　information　flow　direction　in　motor　regions　were　analyzed　and　compared　between　different　training　sessions　RESULTS:　Motor　function　of　all　subjects　was　significantly　improved　in　the　third　test　compared　with　the　first　test　(P　＜　0　01)　More　than　80%　of　connections　were　strengthened　in　the　motor-related　areas　following　two　training　sessions,　in　particular　the　primary　motor　regions　under　the　C4　electrode　Compared　to　the　first　test,　a　greater　amount　of　information　flowed　from　the　Cz　and　Fcz　electrodes　(corresponding　to　supplementary　motor　area)　to　the　C4　electrode　in　the　third　test　CONCLUSION:　Finger　task　training　increased　motor　ability　in　subjects　by　strengthening　connections　and　changing　information　flow　in　the　motor　areas　These　results　provided　a　greater　understanding　of　the　mechanisms　involved　in　motor　rehabilitation
