A new performance test for cervical myelopathy: the triangle step test.

Area of Science:

• Neurology
• Orthopedics
• Physical Therapy

Background:

• Cervical myelopathy assessment often relies on subjective scales.
• Existing performance tests may not be suitable for all patients.
• Objective evaluation of lower extremity motor function is crucial.

Purpose of the Study:

• Introduce and validate the Triangle Step Test (TST) for cervical myelopathy.
• Objectively and quantitatively assess lower extremity motor function.
• Analyze the correlation of TST with established clinical measures.

Main Methods:

• The Triangle Step Test (TST) involves counting steps on a triangular board within 10 seconds.
• 270 cervical myelopathy patients and 60 healthy controls participated.
• Subjects were also assessed using Nurick score, Japan Orthopedic Association score, and finger grip/release test.

Main Results:

• TST scores were significantly lower in cervical myelopathy patients (18.4) compared to controls (25.4).
• TST scores showed significant correlations with other established measures of cervical myelopathy severity.
• Post-surgery, TST scores improved from 16.7 to 21.2, indicating functional recovery.

Conclusions:

• The Triangle Step Test (TST) is a valid and reliable tool for assessing cervical myelopathy.
• TST provides objective, quantitative data on lower extremity motor function.
• The TST effectively measures functional improvement after surgical intervention.
