This study investigated the effectiveness of combining proprioceptive neuromuscular facilitation (PNF) with mobilization techniques in treating text neck syndrome and SMS thumb, two conditions increasingly common due to prolonged use of handheld digital devices. These conditions are characterized by symptoms such as neck pain, reduced cervical range of motion, abnormal head posture, and thumb pain due to repetitive strain on muscles and joints. A total of 15 online gamers aged between 18 and 25 years, all presenting with both text neck syndrome and SMS thumb, were selected for this quasi-experimental study. Participants underwent a structured intervention involving PNF and mobilization techniques three times a week for four weeks. The study used pre- and post-intervention assessments to measure the effects of the treatment. Tools used for evaluation included the Visual Analog Scale (VAS) to assess neck pain, an inclinometer to measure cervical range of motion (ROM), and the Cornell Hand Discomfort Questionnaire (CHDQ) to evaluate thumb discomfort and pain. After four weeks of treatment, significant improvements were observed in all outcome measures. Participants reported a notable decrease in neck and thumb pain, increased cervical ROM, and reduced discomfort in the thumb area. The combination of PNF and mobilization techniques appeared to provide both immediate and functional relief by addressing muscle tightness, joint mobility, and neuromuscular control. These findings suggest that this integrated approach is effective in managing symptoms associated with repetitive stress injuries caused by excessive device usage. In conclusion, the study demonstrates that the combined use of PNF and mobilization techniques offers a safe and effective therapeutic option for young adults suffering from text neck syndrome and SMS thumb. It highlights the importance of addressing modern postural and overuse conditions with targeted physical interventions that improve both pain and functional movement.
