This study was designed to investigate the effects of combined treatment of chiropractic and PNF exercise on musculoskeletal function in forward head posture patients. Thirty patients volunteered to participate in the study as subjects, and they were divided into one of three groups, i.e., chiropractic group (n=10), PNF exercise group (n=10), and combined treatment of chiropractic and PNF exercise group (C+P group; n=10). Subjects in three groups went through each program for 25 min/session, three times/wk for eight weeks. Cervical alignment, cervical muscular strength and endurance, and cervical range of motion were measured and compared among groups and between pre- and post-test utilizing two-way ANOVA with repeated measures. Main results of the present study were as follows: 1) All variables regarding cervical alignment increased significantly in all three groups. The changes in C+P group were more significant than other two groups. 2) All variables regarding cervical muscular strength and endurance increased significantly in all three groups. 3) All variables regarding cervical range of motion increased significantly in all three groups. The changes in ROM regarding flexion and extension in C+P group were more significant than other two groups. It was concluded that all three treatments applied in this study would be effective for functional recovery of the musculoskeletal function in forward head posture patients. Especially, combination of chiropractic and PNF pattern exercise would be the most effective intervention for the patients.
