4.1. Limitations
pain
Despite its benefits, this study also had limitations. This study compared a manual therapy (single intervention approach) with a conventional intervention to alleviate the symptoms of patients with CGH. However, comparing a multimodal approach with a conventional intervention to manage the symptoms would have been an effective way to determine a perfect management line instead of using a single approach in patients with CGH. In addition, outcome variables, such as DCFM strength and cervical ROM, were not assessed. Therefore, future studies need to include a multimodel approach to intervention to identify the most practical and reasonable intervention for managing the symptoms, including pain, DCFM strength, ROM, and functional limitations in patients with CGH.
