Reliability of goniometry in Labrador Retrievers

Area of Science:

• Veterinary Medicine
• Biomechanical Analysis
• Canine Orthopedics

Background:

• Accurate joint range of motion (ROM) assessment is crucial in veterinary orthopedics.
• Goniometry is a common clinical tool, but its reliability requires validation against objective measures.
• Sedation's potential impact on joint mobility needs consideration.

Purpose of the Study:

• To assess the reliability of goniometry for canine joint ROM.
• To compare goniometric measurements with radiographic measurements.
• To determine the effect of sedation on joint ROM in dogs.

Main Methods:

• Sixteen healthy adult Labrador Retrievers were studied.
• Three investigators independently measured carpus, elbow, shoulder, tarsus, stifle, and hip ROM using goniometry.
• Radiographs were taken during sedation; goniometric and radiographic measurements were compared.

Main Results:

• Goniometric and radiographic measurements showed no significant differences.
• Intra- and inter-investigator variability was low (1-6 degrees).
• Sedation did not significantly alter the range of motion for any evaluated joint.

Conclusions:

• Goniometry is a reliable and objective method for assessing joint ROM in healthy Labrador Retrievers.
• Radiographic measurements confirm the validity of goniometric assessments.
• Sedation does not confound joint ROM measurements in this population.
