Characteristics of shoulder impingement in the recreational weight-training population.

摘要: Despite reports implicating subacromial impingement syndrome (SIS) as an etiologic source of shoulder pain among weight-training (WT) participants, a paucity case-controlled evidence exists to support this premise. The purpose study was determine whether WT participants present with characteristics SIS. Additionally, we investigated the role exercise selection those identified having Seventy-seven (154 shoulders) men (mean age, 28) were recruited, including 46 individuals who engaged in minimum 2 days per week; and 31 controls no history participation. Before testing, completed questionnaire summarizing their training patterns. On completing questionnaire, previously validated tests used identify SIS performed on both groups included painful arc sign Hawkins-Kennedy test. When clustered, these have positive likelihood ratio 5.0 for identifying when compared diagnostic gold standards.
