Evaluation of the Screening Effect of Artificial Intelligence Hand Activity Evaluation System for Cervical Spondylosis

Completed

• Conditions: 10-second G&R Test
• Interventions: Diagnostic Test: 10-second hand grip and release test

• Registration Number: NCT06041542
• Lead Sponsor: Guangdong Provincial People's Hospital

Brief Summary

The purpose of this study:

1. Build an artificial intelligence screening tool for cervical spondylosis based on hand function analysis;

2. Verify the accuracy of cervical spondylosis screening tools.

Detailed Description

Cervical spondylotic myelopathy (CSM) has a high incidence in the middle-aged and elderly people. According to clinical research, the surgeon can makes a preliminary assessment of the severity of CSM based on a 10-second grip and release (G\&R) test. The statistics of G\&R test mainly rely on the surgeon's manual counting. When a patient's hand motion speed is too fast, the surgeon's manual counting is prone to error, leading to potential misdiagnosis. We construct and verify the intelligent video analysis system for Grip-\&-release. The system has a high accuracy and inference speed that ensure the proposed model can be used as a screening examination tool for CSM and a medical assistance tool to help decision making during CSM treatment planning.
