DOMS or Soft Tissue Strain?

[gcoe]

Hey Bobby

History:

MS1: Most likely an event, may experience a popping or ripping sensation. Followed by immediate localised pain. If it happens on the field and the patient is really revved up then the delay in pain onset maybe due to the "war in the trenches" effect. But generally should be painful straight away or very shortly afterwords. Symptoms should be localised. and patients should be often able to describe a mechanism. MS1 may show inflammatory patterns

DOMS - always delayed. The onset is slow (execept if it happens over night the patient may not be aware of the slowness of onset but wake up sore) and comes on hours to days depending on the severity of the DOMs. The pain is more generalised across the muscle belly. there is not so much a history of an injuring mechanism undertaking a strenuous movement task that the patient has not been conditioned for. Examples weights, being on the field when deconditioned, going for a run when haven't for a long time, throwing practice when hasn't done it for a long time. Usually the offending task is practiced over and over in the session and it is worse often with eccentric muscle contractions. DOMs doesn't follow an inflammatory pattern although it may a bit worse when one starts to move. Often DOMS will involve more than one muscle or even be bilateral depending on the nature of the offending task.

Examination

Both will be painful on muscle contraction. the MS1 may e painful at rest but worse on contraction while the DOMs may more just on contractions or if it is bed it may be a bit sore at rest.

Palpation - you should be able to localise the MS1 whereas DOMs tenderness is more diffuse.

Have you seen this radiology site? It has some good info from the anatomy/imaging point of view:
