Methods such as casting immobilisation, botulinum toxin injections, and overuse activity have been used to alter the mechanical loads imparted upon the shoulder joint before and after surgical intervention.
Lateral epicondylitis has been reported to be the result of overuse from many activities.
Participants were also asked about their beliefs regarding the possible cause of shoulder pain: unexpected movement; strain during unusal activities; overuse or strain or during regular activities; trauma; sports injury; or unclear (yes/no).
Sick leave during this period was predicted in a multivariable model by a longer duration of sick leave prior to consultation, more shoulder pain, a perceived cause of strain or overuse during regular activities, and co-existing psychological complaints.
Van der Windt et al. [ 20] showed that a relatively large proportion of patients with shoulder syndromes considered strain or overuse in usual activities to be the precipitating cause of their problems.
A longer duration of sick leave prior to consultation, shoulder pain, a perceived cause of strain or overuse during regular activities and co-existing psychological complaints were associated with a higher risk of sick leave during 6 months following consultation.
Although data are lacking it seems logical to presume, for example, that a young 'top-heavy' child would be at increased risk of falling in sports which involve riding on top of animals such as sheep (mutton-busting), camels (camel-racing), horses, or on top of various vehicles, including bicycles; or at increased risk of overuse injury in sport activities involving substantial running activity.
The overuse of resources includes activities such as overgrazing, fuelwood harvesting, or trade of forest products such as fruits and seeds (De Waroux and Lambin 2012; Odihi 2003; Salehi et al. 2008).
Among the extrinsic factors, as well as overuse linked to sports activities, training errors and fatigue must be considered.
