Myofascial pain syndrome is the second most common reason patients seek the help of health care workers. It costs billions of dollars each year in lost revenue due to loss of productivity and other costs.

The treatment of myofascial pain syndrome has been extensively researched and it appears that dry needling and medicinal injections of trigger points are some of the most effective modalities. However, an unwanted side effect common to both these therapies is post-needling soreness. Despite being mentioned in passing by many authors, very little detail is available regarding post-needling soreness.

It is unclear whether post-needling soreness arises from the trigger point itself, or whether the tissue damage caused by the needle insertion is responsible. Therefore, this study was aimed at investigating whether dry needling muscle tissue in asymptomatic subjects (i.e. subjects not suffering from myofascial pain syndrome) resulted in post-needling soreness. Two different dry needling techniques were also compared with a placebo group in order to determine which technique resulted in the least post-needling soreness.

This study was designed as a prospective, randomised, placebo controlled experimental investigation. Sixty subjects were randomly allocated into three equal groups. Group one received the single needle insertion technique and the second group received the fanning dry needling technique. The last group formed the control group and the subjects were treated using the Park Sham Device (placebo needles). All the subjects were between the ages of 18 and 50 and were required to be asymptomatic in the low back region.
