Objectives: To compare the efficacy of two different dry needling (DN) techniques (deep dry needling & peppering) in myofascial pain syndrome (MPS).
Methods: Seventy-two patients, who were diagnosed as MPS at our outpatient clinic were randomly assigned into two groups as deep dry needling (DDN) and peppering. All patients were evaluated four times as: before the treatment and 1-5-12 weeks after the completion of treatment protocol. In each evaluation, Visual analogue scale (VAS), Nottingham extended activities of daily living scale (NEADLS), Beck depression inventory (BDI) scores were recorded. Additionally, all patients were evaluated for the pain felt during the procedure and side effect profile.
Results: Twenty-six patients from DDN group and twenty-eight patients from peppering group accomplished the follow-up period. Both DDN and peppering seem to be effective for relieving pain and depressive symptoms and improving functionality compared to baseline when evaluated on the 1st, 5th and 12th weeks. On the other hand the intergroup analyses showed no significant differences between DDN and peppering groups. The only significant difference between the groups is the lesser pain felt during the procedure in the DDN group.
Conclusion: Both DDN and peppering are effective in MPS and the effects last up to 12 weeks. Also the adverse event profiles of the two techniques are similar. On the other hand, DDN is a painless procedure.
