Stroke is the third leading cause of disability worldwide, resulting in permanent disability in 15% to 30% of survivors. Gait balance dysfunction is the most common complication in stroke patients, and it is estimated that more than 50% of hemiplegic patients are left with lower limb gait balance dysfunction, which causes falls, increases the risk of trauma, affects independence in daily life, and increases the burden on families and society [Walking is a complicated motor pattern [Rehabilitation of the lower limbs seriously affects daily life. The study of tDCS to improve gait balance disorders in the lower limbs after stroke is an emerging area of research in which treatment with tDCS promotes neurological remodeling on the affected side of the stroke and a certain degree of improvement in gait balance. Still, the stimulation site is seen mainly in the cranially related area where anodal tDCS is placed [Until now, there are few reports about treating lower limb gait balance disorder with cathodal transcranial direct current stimulation (ctDCS) after stroke [TDCS as a noninvasive tool for stroke therapy has shown great potential in the acute phases after cerebral ischemia [The initial acute study conducted to mice treated with cathodal tDCS starting after the first 30 minutes of middle cerebral artery occlusion (MCAO) demonstrated that an even earlier intervention using cathodal tDCS led to positive effects on preserving cortical neurons from the ischemic damage, reducing inflammation, and promoting better clinical recovery compared with sham and anodal treatments [
