Inclusion Criteria:

• Between 20 and 50 years of age (inclusive)
• Primary complaint of neck pain with or without symptoms that spread down into one arm
• Overall rating of neck pain intensity is at least 3/10; the overall rating is the average of the participant's rating of current, least, and worst pain experienced over the previous 24 hours on separate numeric pain rating scales where 0 corresponds to "no pain" and 10 corresponds to "worst possible pain"

• Diagnosis of cervical spinal stenosis (narrowing of the central canal that contains the spinal cord)
• History of spinal tumors, spinal infection, cervical spine fracture, or previous neck surgery
• Pending legal action related to current episode of neck pain
