A Novel Insight Into the Challenges of Diagnosing Degenerative Cervical Myelopathy Using Web-Based Symptom Checkers.

DCM symptoms are poorly identified by Web-based symptom checkers, which leads to a large differential of many other common conditions.

Symptom checkers remain an attractive concept with potential. Further research is required to support their optimization.
