three-session ctDCS (2 mA, 20 min). The active (anode) and the returning (cathode) electrodes will be placed bilaterally over the cerebellum (1 -2 cm below inion of occipital bone) and the right buccinator muscle, respectively xbox kinect based balance and mobility training using games from Xbox Adventure Pack for 50 mins.
three-session a-tDCS (2 mA, 20 min), the anode will be positioned over the lesioned M1 (C3, International 10-20 system) and the cathode would be located over the supraorbital area. xbox kinect based balance and mobility training using games from Xbox Adventure Pack for 50 mins.

Changes from the base line, Berg balance scale
The Berg balance scale (BBS) is used to assess the participant's ability to retain stability. The BBS is a widely used test for the assessment of elderly population with impairment of balance and individuals with neurological disorder while sitting, standing, and transferring. This test included both static and dynamic type task. The BBS uses a five-point ordinal scale ranging from 0 (disability) to 4(complete independent performance) and consists of 14 components; the maximum score is 56 points. The scale has been shown to be reliable and valid in stroke patients. A cut-off score of 45 points is used for fall prediction. The BBS involves 14 tasks; a total score of 56. Equipment required for this test were a stop watch or watch with a second's hand and a ruler or other indicator of 2, 5, and 10 inches.
Time frame: Day 3
Timed Up and Go test
Changes from the Baseline, The Timed Up and Go (TUG) test was designed for the evaluation of balance and Measures mobility in people who are able to walk on their own (assistive device permitted) to find out the risk of fall . The subjects will be required to stand up from a chair, walk 3 m, turn around, return to the chair, and sit down. The time taken to complete this task will be measured. The test will be informed three times. The time required to complete this task will be measured from a stopwatch. The average values from 3 trials, with 1-min rest between each trial, were used for data analysis.
Time frame: Day 3
Balance Evaluation Systems Test
Changes from the baseline, Balance Evaluation Systems Test (BESTest) is a 36-item assessment of balance impairments across 6 postural control contexts. Total score of 108 points total, calculated in to a percentage score (0-100%). Also total sub-scores exist for each above listed system. Item-level scores range from 0 (severe impairment) to 3 (no impairment)
Time frame: Day 3
Montreal cognitive Scale
Changes from the base line, The tool used for cognitive impairment is Montreal Cognitive Assessment (MoCA). As there is not at all, fairly effective measuring tool for the early diagnosis of cognitive impairments. MoCA is a successful screening test used for the screening of mild cognitive impairment. Scores of MoCA ranges from 0-30.Interpretation of MoCA indicates that score of 26 and above normal, 18 -25 score indicates low cognitive impairments, 10 -18 score considered normal or moderate cognitive impairment while greater than 10 is considered to be severe cognitive impairments.

three-session a-tDCS (2 mA, 20 min), Sham tDCS followed a similar protocol as Anodal tDCS cerebral (M1) stimulation and arrangement but stimulation for 30 s, after which the current was ramped-down and turned off for the rest of the treatment. xbox kinect based balance and mobility training using games from Xbox Adventure Pack for 50 mins.
Time frame: Day 3
Mini mental state examination (MMSE)
Changes from the Baseline, Mini mental state examination (MMSE): used to screen for cognitive impairment in elderly. The maximum MMSE score is 30 points. A score of 20 to 24 suggests mild dementia, 13 to 20 suggests moderate dementia, and less than 12 indicates severe dementia.
Time frame: Day 3
Johns Hopkins fall risk assessment Tool
Changes from the baseline, Risk of falling was assessed using the Johns Hopkins Fall Risk Assessment score 13,14 ; a score of less than 6 is considered low risk, 6 to 13 is considered moderate risk, and greater than 13 is considered high risk.
Time frame: Day 3
Timed 25-Foot Walk test
Changes from the baseline, Timed 25-Foot Walk (T25-FW) test is a quantitative mobility and leg function performance test based on a timed 25-walk. Two trials will be given to the patient and time will be noted in seconds
Time frame: Day 3
6 min walk test: Distance (meters)
Changes from the baseline, 6 min walk test was used to measure Functional capacity. It is a sub maximal exercise test which can aid in assessing functional capacity of patients with cardiopulmonary diseases, in this test we find out the maximum distance in meters which an individual covers in 6 min without any support.
Time frame: Day 3
tDCS Adverse Effects Questionnaire
Transcranial Direct-Current Stimulation (tDCS) adverse effects questionaire: Do you experience any of the following symptoms or side- effects? Headache, Neck pain, Scalp pain, Tingling, Itching, Burning sensation, Skin redness, Sleepiness, Trouble concentrating, Acute mood change, Others (specify) for each symptom patient can give value (1-4) (1, absent; 2,mild; 3, moderate; 4, severe) If present: Is this related to tDCS? (1, none ; 2, remote; 3, possible; 4, probable; 5, definite)
