Aim and objective: The purpose of this study was to determine the immediate effects of manual therapy technique called inhibitive distraction (ID) on active range of motion (AROM) for cervical flexion in asymptomatic subjects. Methodology: 50 subjects (mean age 24.12 year) with decreased cervical flexion ROM (less than 500) were randomly assigned to an experimental and a control group of 25 subjects each. We used the universal goniometer to measure pre and post intervention cervical flexion AROM in the sagittal plane within a single treatment session. Group A underwent ID and group B received placebo protocol. Result: Though both the groups improved significantly, group AID group result shows more significant in cervical flexion ROM improvement when compared with group B, the control group. Conclusion: Results concluded that ID can be effectively used to enhance the cervical flexion ROM even in asymptomatic subjects.
