Anodal transcranial direct current stimulation was given using a portable battery-driven brain stimulator (The Brain Stimulator v3.0 Deluxe tDCS Kit, using Professional 3x3 inches Amrex Sponge Electrodes). Skin was prepared before application of electrodes by cleaning the skin surface using alcohol swabs. In cerebellar stimulation group (CbSG) a stimulation intensity of 2mA for duration of 20 minutes. In order to avoid sudden initiation and termination of the stimulation the first and last 10 seconds of anodal tDCS application, current will gradually fade in/fade out to avoid any sudden starting or stopping of the stimulation. For the CbSG active anodal electrode was placed over the cerebellum with about 1-2 cm below inion occipital protuberance, whereas the returning cathodal electrode was placed on right buccinator muscle.

The biodex balance system based specific dynamic postural tests were delineated for implementation on both static and dynamic levels. Postural stability tests were performed at three levels of stability: 12 (maximum stability = static), 7 (moderate stability) and 3 (slight stability).

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 the elderly population with impairment of balance and individuals with neurological disorders while sitting, standing, and transferring. This test included both static and dynamic type tasks. 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 was a stopwatch or watch with a second hand and a ruler or other indicator of 2, 5, and 10 inches.

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.

Changes from the base line, immediately after Intervention and then again after 1 hour.

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 into 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)
