While conducting a subjective assessment it is very important to determine severity, irritability and nature of the problem. When considering acupuncture / dry needling the irritability is most important i.e. how easily is the pain provoked, what is pain intensity on VAS for example and how quickly does it settle.
Irritable problems must be treated very carefully with dry needling and manual therapy. Also be on the lookout for inappropriate beliefs/ yellow flags as these should alert you to the need for further caution when applying treatment.
General Rules
With acute, sub acute and especially chronic pain patients, always treat below the pain threshold when using dry needling and manual therapy. It is especially important if there are inappropriate beliefs/ yellow flags as these patients may be more susceptible to central sensitization.
