Clinical Trial Summary

To determine the effects of anodal transcranial direct current stimulation on mobility and balance in post stroke patients.

Description:

Stroke is characterised as sudden onset of neurological dysfunction of central anxious framework that contain cerebral infarction, intra cranial haemorrhage & subarachnoid haemorrhage. Around the globe stroke is the chief cause of incapacity and passing.

The trans-cranial direct current stimulations (tDCS) could be a non-invasive,low cost and capable brain stimulator utilised within the treatment of brain disorders.Two modes of tDCS is utilised is stroke patients,anodal stimulation (increased in excitability) of the lesional half of the globe and cathodal stimulation (decreased in excitability) of the contralesional hemisphere. The transcranial direct current stimulation induced polarity-dependent changes in membrane excitability, with Anodal-tDCS causing depolarisation and cathodal-tDCS causing hyper polarization of membrane potential in neurons of the stimulated area.

The role of Trans-cranial Direct Current Stimulation as a catalyst of recovery in stroke population and found that it's a safe,portable,non invasive brain stimulation technique. T-DCS is able to modulate the excitability of specified brain areas by varying the neuronal membrane potentials that based on the polarity of the current transmitted through the scalp via sponge electrodes. Trans-cranial direct current stimulation is clinically potential for use in stroke recovery because of its ease of use, non invasive-ness and safety.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified Rankin Scale	It is commonly used for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other neurological disorders.The scale runs from 0-6,running from perfect no symptoms to death.The inter rater reliability of Modified Rankin Scale (MRS) for stroke is (0.95)	6 week
Primary	Dynamic Gait Index	Dynamic Gait Index (DGI) was to evaluate functional stability in older people and to evaluate their risk of falling.Its a 4 point ordinal scale,ranging from 0-3, "0" indicates the lowest level of function and "3" indicates the highest level of function.The inter rater reliability of DGI for stroke is (0.96)	6 week
Primary	10 Meter Walk Test	It is to be used for gait speed assesment.According this,individual walk without assistance 10 meters and the time is measured for the intermediate 6 meters. The reliability of 10 meter walk test is (0.97)	6 week
Primary	Fugl Meyer function test:	Fugl Meyer Function (FMA) is used to assess voluntary movements,reflex activity,grasping and co-ordination of affected limb in stroke.It contain 33 task with a scale of 0-2 with maximum scoring of 66.The reliability of FMA scale is (0.95-1)	6 week
