Brief summary
The aim of the present study was to compare the efficacy of three different treatment methods in the management of myofascial pain: masseteric nerve block (MN), trigger point injection(TrP) with local anesthetic (LA) and dry needling (DN).Study Design: 45 subjects aged 18-54 years were randomly assigned to the MN group (n= 15), LA group (n=15) and DN group (n=15).
Detailed description
The study sample consisted 45 patients with masseter muscle originated myofascial pain, were selected in accordance with the following criteria: Patients were grouped according to the treatment they received: dry-needling (DN), TrP injections with local anesthetic (LA) and masseteric nerve block (MNB). Localization of the masseteric trigger points (MTPs) was based on clinician's sense and patients' expressions of pain. Local twitch response was not observable in all case. This procedure was completed by using digital palpation (1.5 Kg), and the clinical examiner's palpation was calibrated using a pressure algometer.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Rate of Pain on Function (PoF) assessed by Numerical pain Scale (NRS) | before the injections (T0, Baseline) | Patients rated their pain on function (pain during chewing or speaking etc.) on a Numeric Rating Scale (NRS) (0-10 where 0 is no pain and 10 is the worst pain imaginable) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Rate of Pain Intensity on Palpation (PoP) | before the injections (T0, Baseline) | Patients rated their pain intensity on masseter muscle by a 4-point Likert-type scale (0 = no pain, 3 = as worst pain imaginable) while a calibrated examiner palpating their masseter muscle. |
| The measurement of pain-free maximum mouth opening (MMO) in millimeters | before the injections (T0, Baseline) | Pain-free MMO was measured as the distance between the incisal edges of the upper and lower incisors while patient's mouth is open as possible without any assistance and without pain in masseter muscle. Three measurements were performed, and their average is recorded. |
