Ogbeivor C, et al. - Through a pragmatic randomized controlled trial conducted in an outpatient community musculoskeletal service of 80 adults, aged 18 years or over, with subacromial impingement syndrome, researchers discovered the efficiency of the lateral approach to subacromial injection, in comparison with the posterior approach, for the treatment of subacromial impingement syndrome. Between weeks 0 and 8, a moderate but statistically and clinically important variation in improvement in daytime pain occurred in favor of the lateral group vs posterior group. Nevertheless, in night-time pain, shoulder function and shoulder pain and disability index scores, no statistically important variations between the groups was noted. For all clinical outcomes between weeks 0 and 8 and between weeks 0 and 12, a statistically and clinically important variation within the groups was observed. Therefore, no notable variations in the treatments could be concluded, although, both forms of treatment were correlated with a notable improvement in shoulder pain, function, and disability.
