Impact of Core Stability Training on Pain and Function in Patient With Shoulder Impingement Syndrome Among Manual Operated Hand Workers

August 26, 2026 updated by: Salah Eid Ahmed Ali, Cairo University
Even at the early stage of employment exposure to mechanical factors such as lifting heavy weights, working with hands at or above shoulder level, and pushing or pulling heavy loads are independent risk factors for new-onset shoulder pain . Shoulder-related problems among workers doing spading are 53.1% and 57.7% among workers brick carrying tasks, these shoulder issues may be the result of repetitive awkward movement (beyond ninety degree raising with abduction position) of the shoulder during these activities .

Detailed Description

The highest prevalence of shoulder impingement syndrome is among slaughterhouses as they are exposed to a combination of repetitive shoulder movements and sustained elevated arm .

Several of workplace physical exposures are implicated in the causation and/or increasing shoulder disorders. Occupational exposures including manual handling heavy lifting, pushing, pulling, holding, carrying), working above shoulder height, and repetitive work are the most frequent causes of shoulder disorders specifically the subacromial impingement syndrome.

Shoulder-related problems among workers doing spading are 53.1% and 57.7% among workers brick carrying tasks, these shoulder issues may be the result of repetitive awkward movement (beyond ninety degree raising with abduction position) of the shoulder during these activities.
