Interexaminer reliability of lumbar segmental mobility tests

Area of Science:

• Orthopaedic Manual Therapy
• Spinal Biomechanics
• Clinical Assessment Reliability

Background:

• Limited research exists on the interexaminer reliability of specific lumbar segmental mobility tests.
• Previous studies often assess total spinal mobility, complicating the interpretation of individual test effects.
• Simulating real-world clinical scenarios requires examining therapists without prior coordination.

Purpose of the Study:

• To evaluate the interexaminer reliability of specific segmental mobility tests for lumbar flexion and extension.
• To address the scarcity of reliability data for individual lumbar mobility tests.
• To investigate reliability in a setting that minimizes potential bias from therapist coordination.

Main Methods:

• Three physical therapists with advanced orthopaedic manual therapy (OMT) training performed standardized lumbar flexion and extension segmental mobility tests.
• Twenty subjects were assessed without additional clinical information beyond a standing inspection.
• Therapists had no prior work history or coordination of manual techniques.

Main Results:

• No significant interexaminer reliability was found for the tested lumbar segmental mobility assessments.
• The findings indicate variability in how therapists apply and interpret these specific tests.
• The lack of reliability suggests current methods may not consistently capture lumbar segmental motion.

Conclusions:

• The tested lumbar segmental mobility tests for flexion and extension lack sufficient interexaminer reliability.
• Current assessment methods may not be dependable for evaluating lumbar intersegmental motion between different clinicians.
• Future research is crucial to develop and validate reliable methods for assessing lumbar segmental mobility.
