Shoulder muscle fatigue has not been assessed in massive rotator cuff tear (MRCT). This study used EMG to measure fatigability of 13 shoulder muscles in 14 healthy controls and 11 patients with MRCT. A hand grip protocol was applied to minimise artifacts due to pain experience during measurement. The fatigue index (median frequency slope) was significantly non-zero (negative) for anterior, midd...

(Hippocrates, Stimson) leverage techniques (Kocher, Milch), and scapular manipulation. Kocher’s manoeuvre was originally described in 1870. The affected arm is flexed at the elbow and adducted against the side of the body. The forearm is rotated externally and the upper arm lifted in a sagittal plane as far as possible and finally internally rotated. There have been many adjustments to this wid...

Regional fascicle strains were recorded in vivo from the pectoralis of carneau pigeons using sonomicrometry during level slow flight, together with regional electromyography (EMG) and deltopectoral crest (DPC) strain measurements of whole muscle force. Fascicle strain measurements were obtained at four sites within the pectoralis: the anterior (Ant), middle (Mid) and posterior (Post) sternobrac...

Cervical disorders and the shortening of pectoralis minor are advocated to play an important role in patients with subacromial pain syndrome, despite absence evidence. This study aimed compare deep cervical flexor muscle function between syndrome controls. Secondarily, this analyze relationship clinical tests disability among patients. is a case-control 32 [mean age: 33 ± 6.9 years; sex: 22 (65...

BACKGROUND The advantages of dual-plane, partially submuscular breast implants are well documented. Standard conversion techniques to dual-plane positioning use marionette sutures and internal capsulorrhaphy sutures from the lower edge of the pectoralis major muscle to the anterior capsule or breast fascia within the subglandular plane. These techniques are limited by high rates of postoperativ...
