Electromyographic Activity Of Various Muscles During Sit-to-stand In Patients With Stroke: A Meta-analysis

Aims:-To providea comprehensiveinformationaboutanalysisof activationof variousmuscles during Sit-to-Standinpatientswithstroke.Todetermineifthereexistsanycommonpatternof muscleactivation.Togivedirectiontofuturestudiesregarding themusclestobeinvestigated during Sit-to-Stand. Methods-A literature search was performed with help of the most commonlyuseddatabasei.e.PubMedtoselectthestudiesrelatedtoelectro-myographicactivities ofvariouslowerextremity,trunkandupperextremity musclesduringSit-to-Standactivity, publishedtill2016.TheInclusioncriteriaforthestudy wereProspectiveorretrospectivecohort studies,studiesthatincludedonly participantswithstrokeleadingtohemiparesisand/oralong withhealthy participants ascontrolgroupandstudiesthatmeasuredtheEMGactivity ineither trunkmusclesand/orlimbmusclesduring sittostand.Theexclusion criteriawere iftheir populationofinterestalsoincludedpatientswith otherneurologicalconditionsandstudiesinany language other than English.Twoindependentinvestigatorsassessedthe studiesbasedon inclu-sion and exclusion criteria. Keywordsused duringthesearch wereElectromyography, Stroke,Sit-to-Stand.Thestudieswerethoroughly evaluatedwithrespecttotheSit-to-Stand procedureandvariety ofmusclesthatwereinvestigatedthroughEMGanalysis. Results: Withthe helpof givenkeywords,abstracts/articlesof 21studieswereretrievedfromthedatabase.After initial screening oftheabstracts12studieswereselectedforindepthanalysis.Variouslowerextremity musclesincludingTibialisAnterior,Soleus,Quadriceps,Vastusmedialis,GluteusMaximus were investigatedinthe studies.In2studies,Trunkmuscleswereinvestigatedwhereasinone study Tricepsmuscleactivity wasanalyzedduring Sit-toStandactivity inpatientswith stroke. Conclusion:Fromthisstudy itcanbecon-cludedthattheactivityofTibialisAnterior musclewasinvestigatedmorefrequentlybyvariousresearchersfollowedbytheactivityof Soleus and Quadriceps muscle.
