Text Neck Syndrome is increasingly common in young adults due to prolonged smartphone use and is linked to postural changes and impaired sensorimotor control. Although its effects on visual-vestibular integration, balance, and proprioception are still unknown, Instrument-Assisted Soft Tissue Mobilization (IASTM) may improve neuromuscular function by enhancing afferent input and mechanoreceptor stimulation. This study investigates whether IASTM can improve sensorimotor processing in individuals with Text Neck Syndrome.
