Shoulder proprioception gives information regarding arm joint position and movement direction. Several studies have investigated shoulder proprioceptive acuity in patients with subacromial impingement syndrome (SIS); however, differences in protocols and between-subjects designs have limited scientific inferences regarding proprioception and SIS. We aimed to determine within-subject differences...

BACKGROUND The shoulder's subacromial space is of significant clinical interest due to its association with rotator cuff disease. Previous studies have estimated the subacromial space width to be 2-17 mm, but no study has measured in vivo subacromial space width during shoulder motion. The purpose of this study was to measure the in vivo subacromial space width during shoulder elevation in pati...

In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...

Arthroscopic subacromial decompression (ASD) is frequent operation on shoulder joint. Acromioplasty or subacromial decompression is operative technique for removal of mechanical barrier, which restricts physiological motion of humeral head, during abduction and external rotation movements of shoulder joint. This article explains a technique of arthroscopic subacromial decompression and our resu...

Definition One of the challenges for the diagnosis of subacromial impingement is the multiplicity of conditions with similar symptoms and variable clinical presentation. With no single aetiology, the clinical diagnosis of subacromial impingement has also suffered from a “lack of consensus on diagnostic criteria, case definition and even nomenclature”. For want of clarity, we suggest the followi...

[Purpose] This review article is designed to expose the application of sonography in shoulder pain after stroke. [Methods] A range of databases was searched to identify articles that address sonography examination, with or without ultrasound guided corticosteroid injection for hemiplegic shoulder pain (HSP). The electronic databases of PubMed, CENTRAL, CINAHL, Cochrane Library, Medline were sea...

This study investigated the role of acromion morphology in the aetiology of chronic subacromial impingement syndrome. Forty five patients with chronic subacromial impingement syndrome were included in the study. They were distributed into three groups according to their acromion types: six (13.3%) patients had type 1, 24 (533%) patients type 2 and 15 (333%) patients type 3 acromion. Constant sc...
