The two cases of multiple fatigue fractures that these authors investigated most likely resulted from overuse activities in soldiers and untrained subjects, as the authors observed that multiple fatigue fractures in three or more areas occurred in two healthy male patients without any under-nutrition, dyscrinism, long-term rheumatoid arthritis or osteoporosis.
Most studies have found instead that the pains — which can affect nearly half of all children — result from brittle bones and physical activity, in particular overuse from running, climbing and jumping during the day.
However, any activity that involves overuse of the wrist extensor or supinator muscles may be incriminating.
The ER activity is an overuse protocol targeting the external rotators and minimizing involvement of other shoulder muscles.
Marching and running (36%) were the most common activities associated with overuse-related MSDs, followed by carrying and lifting loads (10%) and other organised physical exercise excluding marches and combat training (6%).
Although there are similarities in bone formation and vascular calcification and both disorders share several common risk factors (aging, female sex, low physical activity, smoking, alcohol overuse, renal and metabolic diseases), 1 traditionally they are regarded as separate but coexisting diseases.
Previous investigations indicate that ground subsidence caused by tectonic movements or anthropic activities, such as groundwater overuse, is a major concern in land-use planning, infrastructure sustainability evaluation, and engineering construction [4].
It has been proposed that pain improvement allows increased joint activity leading to subsequent overuse [ 8].
Overuse activities can increase the risk of multiple fatigue fractures in soldiers or untrained subjects.
Local alteration of the water cycle by human activities has led to global overuse of water resources.
