Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patients' subjective pain experience | one year | Pressure pain threshold (PPT): An algometer will be used to assess PPT. The algometer consists of a 1 cm2 rubber tipped plunger mounted on a force transducer. The pressure will be applied over the examined trigger point. The participants will be instructed to point when the sensation changed from pressure to pain. The mean of three trials will be calculated and used for analysis. |
