Transcranial Direct Current Stimulation vs Pilates Core Training in Stroke

The goal of this clinical trial is to compare the effects of transcranial direct current stimulation and pilates based core stability training on gait and balance in stroke patients. The main question\[s\] it aims to answer are: * is there an effect of transcranial direct current stimulation and pilates based core training on gait and balance * Is there a significant effect of tDCS over Pilates-based core training Participants will be assigned to three groups: * Group 1: will receive 18 sessions(3 sessions/week 20 minutes each) of anodal tDCS in addition to conventional physical therapy exercises * Group 2: Will receive 18 Pilates exercise sessions over a period of 6 weeks (3 sessions / week) in addition to conventional physical therapy exercises. * Group 3: Will receive conventional physiotherapy program Researchers will compare the transcranial direct current stimulation group with the pilates exercise group to see if one of them is superior to the other on balance and gait.
