Registered outcomes 3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Between-Needle Difference in Palpation-Evoked Masseter Pain Reduction From Baseline to Day 14 | Baseline and Day 14 (14 days after injection) | Palpation-evoked masseter pain was assessed separately on each side using an 11-point Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst possible pain). At baseline and day 14, pain was recorded at the most painful trigger point identified during each assessment. Pain reduction was calculated as baseline NRS minus day 14 NRS for each side. The primary outcome was the within-participant difference in pain reduction between the 30G and 26G needle interventions (30G minus 26G). Positive values indicated greater pain reduction with 30G. | ClinicalTrials.gov |
| Secondary | Between-Needle Difference in Palpation-Evoked Masseter Pain Reduction at Day 7 | Baseline and Day 7 | Palpation-evoked masseter pain was assessed separately on each side using an 11-point Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst possible pain). Pain reduction was calculated as baseline NRS minus day 7 NRS for each side. The within-participant difference in pain reduction between the 30G and 26G needle interventions was calculated as 30G minus 26G. Positive values indicated greater pain reduction with 30G. | ClinicalTrials.gov |
| Other | Overall Procedural Pain During Masseter Trigger Point Injection | Day 0 (within 60 seconds after each injection) | Overall procedural pain was assessed separately for the 26G and 30G needle interventions using an 11-point Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst possible pain). Participants rated the entire injection procedure, including skin penetration, intramuscular needle manipulation, and lidocaine administration. Pain was recorded within 60 seconds after each injection. Within-participant pain scores were compared between needle gauges. | ClinicalTrials.gov |
