About

The objective of the present study is to analyse the diagnostic validity of 8 neurodynamic and/or orthopedic tension tests using magnetic resonance imaging as the Gold Standard.

Full description

Lumbar radiculopathy is a nerve root disorder which affects quality of life of the patient and it is considered as an important health problem. Therefore, its correct diagnosis is essential. The objective of the present study is to analyse the diagnostic validity of 8 neurodynamic and/or orthopedic tension tests using magnetic resonance imaging as the Gold Standard.

This is an epidemiological study of randomized consecutive cases which was observational, descriptive, transversal, double blinded and followed the STARD (Standards for Reporting Diagnostic accuracy studies) declaration.

Enrollment: 1,887 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
