Validation of the Cervicothoracic Differentiation Test

pain with motion

The goal of this clinical trial is to compare the effects of two spinal manipulations in
 adults between the ages of 18-65 based on the results of a non-invasive clinical test. The
 main question it aims to answer is: • Does matched or unmatched region of manipulation based
 on the CTDT result in greater reduction of pain levels and improvement in range of motion in
 adults with neck pain compared to unmatched manipulations? Participants will be asked to:
 
 - rate their pain with neck movement, complete brief questionnaires about their pain,
 
 - have their neck range of motion measured,
 
 - perform a test known as the cervico-thoracic differentiation test (CTDT),
 
 - receive either a cervical or thoracic manipulation,
 
 - repeat the range of motion measurements.
 
 - A second session will occur 7-10 days later where questionnaires and range of motion
 measures will be repeated.
 
 Researchers will compare the effects of manipulation matched to CTDT test result to
 individuals in the unmatched CTDT manipulation group to see if the CTDT may indicate which
 region will provide a greater treatment effect for individuals with neck pain.
