[Purpose] The aim of the present study was to identify the effects of an unstable support surface (USS) on the activities of trunk and lower extremity muscles during pulley-based shoulder exercise (PBSE). [Subjects] Twenty healthy college students were included in this study. [Methods] Surface EMG was carried out in twenty healthy adult men. The activities of trunk and lower extremity muscles p...

There are few published data on the ranges of available motion at the shoulder and no clinical technique for the assessment of three dimensional movement. An electromagnetic movement sensor (Isotrak), which makes three dimensional measurements of shoulder movement and measures the ranges of flexion, extension, abduction in the neutral position, abduction preceded by external rotation, and inter...

OBJECTIVES A lesion in the spinal accessory nerve is typically iatrogenic: related to lymph node biopsy or excision. This injury may cause paralysis of the trapezius muscle and thus result in a characteristic group of symptoms and signs, including depression and winging of the scapula, drooped shoulder, reduced shoulder abduction, and pain. The elements evaluated in this long-term follow-up stu...

Eight nonimpaired subjects participated in a wheelchair exercise test using a motor-driven treadmill in order to study the effect of rear wheel camber on wheelchair ambulation. The test consisted of four runs with rear wheels in 0, 3, 6, and 9 degrees camber at four speed steps of 2, 3, 4, and 5 km/hr. There were no significant effects upon oxygen cost, heart rate, and mechanical efficiency. Th...

Using a dynamic biomechanical model of malunion of the shoulder, we have determined the change in deltoid force required for abduction with various combinations of superior and posterior displacement of fractures of the greater tuberosity of the humerus. We tested eight fresh human cadaver shoulders in a dynamic shoulder-testing apparatus during cycles of glenohumeral abduction from 0 degrees t...

OBJECTIVE To evaluate the inter-rater and intra-rater reliability of ultrasonographic measurements of axillary recess (AR) thickness in healthy individuals, and to analyze the factors affecting the thickness of the AR capsule. METHODS We recruited 20 healthy individuals (10 male, 10 female) with a mean age of 37 years (standard deviation ±10). Two physiatrists (an experienced and a novice rat...

BACKGROUND It has been suggested that limited active ROM of reverse shoulder prostheses relates to lack of strength. However, the postoperative strength has not been quantified. QUESTIONS/PURPOSES We therefore measured joint torques in patients with reverse shoulder prostheses and correlated torques with functional scores. METHODS We recruited 33 patients (age, 72 ± 8 years) with a reverse ...

[Purpose] The aim of our study was to compare the initial effects of scapular proprioceptive neuromuscular facilitation techniques and classic exercise interventions with physiotherapy modalities on pain, scapular dyskinesis, range of motion, and function in adhesive capsulitis. [Subjects and Methods] Fifty-three subjects were allocated to 3 groups: scapular proprioceptive neuromuscular facilit...

Objectives: The purpose of this study is to report the effect hominis placenta pharmacopuncture and chuna manual therapy in patients with frozen shoulder.Methods: Frozen shoulder was treated therapy, overall pain measured by visual analog scale (VAS), range motion (ROM) movement evaluated measuring passive abduction external rotation active hand blade test.Results: After treatment, reduced, ROM...

Abstract Background Reverse shoulder arthroplasty (RSA) is a valuable solution for patients with pain or injury primarily due to rotator cuff tear secondary traumatic events. Nevertheless, several complications are known appear, the most frequent being scapular notching (SN) on inferior and posterior neck. Controversial data exist about clinical relevance of SN. Since further consequences still...
