Background: Smart devices including smart phones have many benefits. However, prolonged used may aggravate cervical pain and postural deformity. Smart devices with appropriate applications (apps) may be useful cost-effective and easy-to-use instruments to relieve cervical pain and improve range of motion (ROM).
Objectives: To review recent experimental studies on smart device-based apps on cervical pain and postural ROM improvement.
Design: Systemic review study.
Methods: Ten articles were selected through bibliographic searches and successive and exclusion procedure of the PubMed, ScienceDirect, and Google Scholar. Out of initial 1,046 articles, 98 articles were selected from abstract review. 33 articles were selected for full article review. Final 10 research articles were selected.
Results: Three static ROM feasibility, two active ROM feasibility, four self-management promotion, and one pre/post research study articles were included. Smart device with artificial intelligent (AI) based app were utilized promote adherence to physical activity.
Conclusion: Smart device apps steadily showed high feasibility even for research purpose. Studies on AL and machine learning apps showed mixed results for need for wider and precision application.
