Transcranial Direct Current Stimulation (tDCS) in managing pain and recovery: A clinical case of radial capitellum fracture

Introduction: The management of pain and functional recovery following a radial capitellum fracture poses a significant clinical challenge, especially in individuals whose professions, such as physiotherapy, demand optimal joint functionality. Transcranial Direct Current Stimulation (tDCS) emerges as a potential nonpharmacological intervention for pain management, necessitating exploration in the context of orthopedic injuries. Case presentation: A 41-year-old male physiotherapist presented with a MASON 2 radial capitellum fracture following a fall, experiencing notable pain (NPRS 6/7) and functional impairment (DASH 45/100, PRTEE 43/100). Conservative management, involving immobilization and potential surgical consideration, was employed, followed by tDCS for pain management. Post-tDCS, significant improvements were observed in pain and functional scores (NPRS to 0, DASH to 14.2, PRTEE to 7), alongside enhancements in range of motion and muscle strength. Clinical discussion: The application of tDCS showcased notable efficacy in pain reduction and functional improvement, highlighting its potential in augmenting pain management strategies post-fracture. However, the variability in responses and lack of standardized application protocols necessitate further research to optimize its clinical utility. The balance between immobilization for fracture healing and mobilization for preventing stiffness and facilitating recovery was pivotal in managing the fracture and ensuring functional improvement. Conclusions: This case underscores the potential of tDCS in managing pain and facilitating functional recovery in radial capitellum fractures, warranting further exploration and standardization of its application in clinical practice. The integrated, patient-centric approach, involving interdisciplinary collaboration and personalized care, was crucial in ensuring positive outcomes and provides a framework for managing similar orthopedic cases
