Rehabilitation following injury of the rotator cuff
2003
The main aim of this paper is to compare two diffrent rehabilitation tecniques for treatment of the shoulder joint following injury of the rotator cuff. The seriousness of the pathology means patients generally have to endure a considerable period during wich use of the joint in question is impossible
On the history of torsional stress concentrations in shafts: From electrical analogies to numerical methods
2014
This article proposes a retrospective on experimental and numerical methods developed throughout the past century to solve the torsion problem in shafts, with particular emphasis on the determination of shear stress concentration factors in discontinuities of typical use in shaft design. This article, in particular, presents the theory and related solutions distinguishing between two classes of geometries: shafts with constant cross section and axisymmetric shafts with variable diameter. Emphasis is given to approaches based on physical analog methods and, in particular, those based on electrical analogies proposed since about 1925. Experimental methods based on structural physical models …
An Instrument-Assisted coracoid pain test: an exploratory diagnostic accuracy study
2022
The coracoid pain test (CPT) could contribute to the diagnosis of frozen shoulder (FS) with palpation. However, due to assessor performance these values might be unreliable. Therefore, the aim was to explore the diagnostic accuracy of an instrument-assisted CPT and two alternative approaches (pain severity and side comparison) for assistance in the diagnosis of FS. Patients with FS and healthy age-matched controls were recruited. All participants underwent the instrument-assisted CPT on both shoulders with a pressure algometer. Sensitivity, specificity, and likelihood ratios were determined for the three approaches. In total, 35 patients with FS and 35 healthy participants were included. Th…
Adhesive capsulitis in a patient affected by KBG Syndrome
2021
Background and Case presentation: KBG syndrome is a multiple congenital anomaly syndrome with variable presentation. Many physical anomalies also affect the orthopaedic field. We present a case of a young woman with diagnosis of KBG syndrome that is also affected by joint stiffness and adhesive capsulitis to the shoulders. Discussion: Many other cases have been reported to present joint stiffness and formation of keloids. Adhesive capsulitis is known to be related to autoimmune pathologies and endocrinological disorders. KBG syndrome is caused by heterozygous mutation in ANKRD11 gene and few patients with hypermobility of the joints have also been reported. Conclusions: The KBG syndrome mig…
Ventastega curonica and the origin of tetrapod morphology.
2008
The gap in our understanding of the evolutionary transition from fish to tetrapod is beginning to close thanks to the discovery of new intermediate forms such as Tiktaalik roseae. Here we narrow it further by presenting the skull, exceptionally preserved braincase, shoulder girdle and partial pelvis of Ventastega curonica from the Late Devonian of Latvia, a transitional intermediate form between the 'elpistostegids' Panderichthys and Tiktaalik and the Devonian tetrapods (limbed vertebrates) Acanthostega and Ichthyostega. Ventastega is the most primitive Devonian tetrapod represented by extensive remains, and casts light on a part of the phylogeny otherwise only represented by fragmentary ta…
Neck and Shoulder Muscle Activation Among Experienced and Inexperienced Pilots in +Gz Exposure
2017
Background The aim of the present study was to compare differences in electromyography (EMG) activation of the neck and shoulder muscles between groups of inexperienced and experienced pilots during controlled +Gz exposure in a centrifuge. Methods The subjects were volunteer cadets (inexperienced group) and lieutenants (experienced group) undergoing their first centrifuge training. The first group did not have any high performance aircraft (HPA) experience, while the latter one had a 1-yr experience of intense flying of HPA. During the centrifuge run, EMG activity was recorded from the left and right shoulder, neck flexor, and neck extensor muscles. Results The pilots without HPA experience…
The effectiveness of 12 months' intensive shoulder strength training on disability, health-related quality of life and shoulder function after rotato…
2017
This study examined the effectiveness of intensive shoulder strength training on disability, health-related quality of life (HRQoL) and shoulder function in patients who had undergone rotator cuff repair (RCR). In addition, the self- report section of the American Shoulder and Elbow Surgeons Standardized Assessment Form (ASES) was cross-culturally adapted to the Finnish language and the psychometric properties of the Finnish version were assessed. Patients with a rotator cuff tear (aged 41-62 years) were randomized into an exercise group (EG, n=35) or a usual care group (UCG, n=32) after RCR. Disability was assessed with ASES questionnaire and quality of life with Short- Form 36 Health Surv…
Impaired Trunk Posture in Women With Fibromyalgia
2018
A cross-sectional study.The main goal of the study was to analyze posture of Fibromyalgia syndrome (FMS) in women compared with healthy subjects to establish if posture assessment could be useful to characterize the syndrome. Secondarily, we explored the impact of sedentary behavior on trunk posture.Pain has been associated with poor static postures, however there is little information on the effect of FMS, which is characterized by widespread pain, on trunk posture.One hundred eighteen women with FMS and 110 healthy counterparts participated in this study, in which trunk posture was assessed. The thoracic kyphosis, forward head position, and shoulder position (basal and maximum protraction…
Effects of asymmetrical exercise demands on the symmetry of skin temperature in archers
2020
Abstract Objective: To analyse skin temperature asymmetries in response to asymmetrical exercise demand in archers. Approach: The skin temperature of the trunk and upper limbs was measured in 30 archers with an infrared camera at three different moments: before (Pre), immediately after (Post), and 10 min after (Post10) a simulated competition (18 warm-up shots and 72 qualifying round shots). Relative and absolute asymmetries were determined. Stepwise multiple linear regressions were performed using the variations of relative and absolute skin temperature asymmetries as predicting variables, and sex, age, experience, body mass index, bow mass, bow power, and rate of perceived exertion of com…
A case of bilateral luxatio erecta
2008
AbstractLuxatio erecta is an uncommon form of glenohumeral dislocation. Cases of bilateral inferior shoulder dislocation (luxatio erecta) are very rare, and only ten cases have been described in literature. We describe a case of a woman with bilateral luxatio erecta of the shoulders treated with close reduction, immobilization and rehabilitation. The patient had fallen downstairs while clinging to both lateral banisters.
