Transcranial direct current stimulation (TDCS) is a relatively new treatment approach for stroke recovery. TDCS is a neuromodulation method which involves application of weak direct current stimulations over the scalp via electrodes. It could induce plasticity via modulation of resting membrane potential and modification of spontaneous discharge rate.~TDCS has been shown to have beneficial effects on mobility, muscle strength, motor learning, lower limb function, balance, gait, functionality and walking ability in post stroke patients. TDCS appears to be a promising intervention for stroke patients however its effects are not significant if used in isolation. Thus, it should be used as an adjunct to some other treatment.~Review of available literature indicates TDCS can be a good option in short and intermediate run but its effects in the long run have not been studied yet. Furthermore, to the best of my knowledge there is little literature available about the long-term effects of TDCS on muscle strength in subacute stage. Therefore, this study is designed to test the long-term effects of TDCS stimulation on subacute stroke patients.
Loss of strength is a common complication post stroke which leads to loss of balance and walking ability. Variety of interventions are adopted to improve muscle strength after stroke. These include progressive resistance training, specific task training or functional training, functional electrical stimulation and high intensity aerobic exercises
