Crack or no crack: does the sound of spinal manipulation boost pain relief?
NCT ID NCT06934122
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at whether hearing a popping sound during spinal manipulation changes how much pain and disability people feel, and how satisfied they are with the treatment. 38 adults with non-specific neck and upper back pain will receive massage and spinal manipulation. Researchers will compare those who hear an audible crack versus those who don't, measuring pain and satisfaction before and 48 hours after treatment.

- What this could lead to
- If it works, this could help therapists understand whether the sound of a joint popping influences how much pain relief and satisfaction patients feel.

- This is a very small study (38 people) and only looks at short-term effects (48 hours). The results may not apply to everyone with neck pain.
