CHRONIC PAIN
Some potential limitations of this study are that data was collected only from a single setting, and follow-up was just up to 12 weeks, so in the future, researches should be conducted based on several treatment sessions with even longer follow-ups, and multicenter randomized controlled trials are needed. A force applied in this technique was not assessed, so dosage remains a matter of concern for further studies. Chronicity of pain should have been identified as acute, and chronic pain might have different effects on treatment outcome.
