BACKGROUND: Text neck syndrome is an overuse condition that has become a global problem for all ages who use smartphones. Although therapeutic approaches are used to manage text neck syndrome, relatively little evidence exists on efficacy. This study aimed to investigate the effects of proprioceptive neuromuscular facilitation (PNF) techniques on individuals with text neck syndrome. METHODS: Thirty-eight participants with text neck syndrome were randomly allocated to either the experimental or control group. Both groups performed the program including cervical range of motion, strengthening, and posture correction exercises for 6 weeks, 3 days a week, once a day for 10 repetitions. In the experimental group were included in a PNF program 3 days a week for 6 weeks. In the program, contract-relax and replication techniques were used. Pain intensity, cervical range of motion, cervical muscles' endurance, posture, and disability were assessed. Outcome measures were assessed at baseline and after 6 weeks. RESULTS: Pain intensity, neck muscle endurance tests, posture, and disability scores significantly improved in both groups (p < 0.05). The cervical range of motion values in all directions were significantly increased only in the experimental group (p < 0.05). The improvements in pain intensity, neck muscle endurance tests, posture, and disability scores were greater in the experimental group compared with the control group (p < 0.05). CONCLUSION: PNF could be used effectively to reduce neck pain and disability level and enhance cervical range of motion, cervical muscles' endurance, and posture in individuals with text neck syndrome.
