1. Relieves pressure on the cervical spine: Stabilizes the neck to reduce range of motion and lower the load on intervertebral discs and facet joints; suitable for cases involving prolonged head-down posture or acute sprains.
2. Alleviates pain: Limits abnormal cervical movement to reduce nerve compression; can be used in conjunction with heat therapy or low-frequency electrical stimulation.
3. Promotes tissue repair: Provides stability that aids blood circulation and the resolution of inflammation; recommended for use alongside physical therapy.
4. Corrects poor posture: Restores the natural physiological curvature through continuous traction; requires complementary muscle-strengthening exercises.
5. Supports postoperative recovery: Protects internal fixation hardware and prevents the displacement of bone grafts; typically requires continuous use for 6–8 weeks.
