They described a fluctuating course of chronic symptoms following an initial acute episode, temporarily improved by cessation of precipitating activity.
Subtypes of breakthrough pain include incident (often predictable and precipitated by activity or movement), idiopathic or spontaneous, and end-of-dose pain.
Depending on the particular injury, treatment may include discontinuation of the precipitating activity only, discontinuation of all training activities, or, for more serious injuries, crutches or surgery.
For minor injuries, healing may take as little as three to six weeks, with avoidance of the precipitating activity and with continued cross-training followed by a gradual return to the pre-injury level of participation.
After the initial descriptions, headache precipitated by sexual activity was well defined.
Headache precipitated by physical activity or Valsalva manoeuvre (e.g. coughing, laughing, straining) 7.
The pain attacks were spontaneous or less frequently precipitated by physical activity, and lasted from 30 min to 2 h.
The headache was usually associated with nausea and phonophobia, often precipitated by physical activity and would last for 2 to 3 days and remitted spontaneously.
Neuroimaging should be considered in patients presenting with atypical headache features, a new onset headache, change in previously headache pattern, headache abruptly reaching the peak level, headache changing with posture, headache awakening the patient, or precipitated by physical activity or Valsalva manoeuvre and abnormal neurological examination.
The intensity of the phosphorylated ATF-2 band represents the relative p38 MAPK kinase activity precipitated by antiphospho-p38 MAPK antibody.
