Effect of Transcranial Direct Current Stimulation and Pelvic Proprioceptive Neuromuscular Facilitation in Stroke Patient

Stroke is a leading cause of long-term disability and commonly results in impaired trunk control, postural instability, balance deficits, and reduced functional mobility due to disrupted sensorimotor integration, impaired proprioceptive processing, and decreased cortical excitability. Trunk control is a key determinant of balance, gait performance, and functional independence, making it a critical target in stroke rehabilitation. Transcranial Direct Current Stimulation (tDCS) enhances cortical excitability and promotes neuroplasticity through a top-down mechanism, while Pelvic Proprioceptive Neuromuscular Facilitation (PNF) improves trunk-pelvic control, weight shifting, and sensorimotor integration through a bottom-up proprioceptive facilitation mechanism. Emerging evidence suggests that combining tDCS with Pelvic PNF may improve trunk function and mobility in stroke survivors, supporting the concept of synergistic neuromodulation and motor facilitation. Despite the documented benefits of tDCS and Pelvic PNF individually, the combined application of these interventions remains insufficiently explored, particularly in subacute stroke patients. Most previous studies have focused on gait training, robotic rehabilitation, or other task-oriented interventions, with limited emphasis on trunk-focused pelvic PNF and postural control outcomes. Furthermore, few high-quality randomized controlled trials have evaluated whether simultaneous targeting of central neuroplasticity and peripheral proprioceptive facilitation provides superior improvements in trunk control, balance, and functional mobility. Therefore, this study aims to address this important clinical and methodological gap by investigate the combining effect of Pelvic PNF and tDCS, potentially establishing an evidence-based rehabilitation strategy that optimizes functional recovery after stroke.
