Subcutaneous sterile water injections for chronic neck and shoulder pain following whiplash injuries

In many cases of whiplash injury symptoms persist and do not respond to treatment. There is uncontrolled evidence to suggest that intracutaneous injections of sterile water might help. Since that route may be unacceptable to patients the subcutaneous route is used in the randomised trial reported here. 40 patients with whiplash syndrome, mean age 46 years (24-73) were given subcutaneous injections of 0·3-0·5 ml sterile water or saline over tender and trigger points in the neck and shoulder. A maximum of three treatments were given during the first two months of the study and the patients were followed up for 8 months. The accidents had occurred 4-6 years previously. X-ray examinations revealed no traumatic spinal lesions. Neck mobility and pain levels were evaluated by a physiotherapist immediately before and after the first treatment and after 1, 3, and 8 months. After 3 months, the mean total mobility of the cervical spine had increased by 39° in the sterile water group and 6° in the saline group (p
