Upper back crack may cure neck pain, study hints
NCT ID NCT06926738
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a hands-on adjustment of the upper back (thoracic spine) can reduce pain and improve neck movement in people with chronic neck pain. 42 adults with neck pain for at least 3 months received either the real adjustment or a fake (sham) version. Researchers measured pain levels, neck range of motion, and muscle activity right after treatment and over two weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Upper thoracic spine manipulation (a hands-on technique to adjust joints in the upper back)
- What this could lead to
- If it works, this could offer a simple, drug-free option to ease chronic neck pain and improve neck movement.
- What could go wrong
- This is a small, completed study with only 42 people, so results may not apply to everyone. The effect may be short-term or no better than a sham procedure.

Male and female subjects diagnosed and classified as having chronic non-specific NP with mobility disorders based on clinical guidelines of NP: * Having NP for at least 3 months that may be associated with referred shoulder or upper extremity pain (Blanpied et al., 2017; Erdem et al., 2021; Puntumetakul et al., 2015). * Present with a limitation of cervical ROM and their pain can be provoked by sustained end-range spinal movements or positions will be included (Blanpied et al., 2017). * Patients present with unilateral or bilateral symptoms will be included (Blanpied et al., 2017; Yang et al., 2015). 2. Age between 18-40 (J. Dunning \& Rushton, 2009) 3. Negative four tests of the Wainner cluster to exclude NP with radiating pain (Wainner et al., 2003). 4. Hypomobility of at least one of the upper thoracic vertebrae (T1-T4) during segmental mobility assessment (Ssavedra-Hernández et al., 2011). Exclusion Criteria: 1. Subjects diagnosed as cervical radiculopathy or myelopathy (Ssavedra-Hernández et al., 2011). 2. A history of whiplash injury, past cervical or thoracic surgery, rheumatoid arthritis, spinal fracture, heart disease, a recent significant trauma, and meningitis (Joshi et al., 2020; Puntumetakul et al., 2015). 3.
