pressure pain sensitivity maps of the neck Shoulder Region in breast cancer survivors
Pain Medicine, 2016Co-Authors: Elena Caromoran, Carolina Fernandezlao, Lourdes Diazrodriguez, Irene Cantarerovillanueva, Pascal Madeleine, Manuel ArroyomoralesAbstract:Objective. The aim of the present study was to report pressure pain sensitivity topographical maps of the frontal and dorsal parts of the Shoulder Region, and locate the pressure pain sensitive areas in breast cancer survivors compared with matched healthy control subjects. Methods. Twenty-two breast cancer survivors (BCS) and 22 matched control subjects participated. A numeric pain rating scale of the neck-Shoulder area and pressure pain thresholds (PPTs) was assessed bilaterally over 28 points in the frontal and dorsal neck-Shoulder area. Topographical pain sensitivity maps of the upper trapezius, pectoral, and anterior deltoid areas were computed. Results. A three-way analysis of variance was carried out to evaluate the differences in PPTs. The BCS reported spontaneous neck pain (mean ± SD 3.6 ± 2.8), pain in the affected Shoulder (4.3 ± 2.7), and pain in the non-affected Shoulder (0.9 ± 1.8). Additionally, the BCS exhibited bilaterally lower PPTs in all the measurement points as compared with the control subjects ( P < 0.05). The PPTs were lower at the superior part of the trapezius muscle ( P < 0.001), the musculotendinous insertion, the anterior part of the deltoid muscle ( P < 0.001), and the tendon of the pectoral muscle ( P < 0.001) as compared with the control subjects. Conclusions. The results suggest the sensitization processes in the BCS and give preliminary evidence to most sensitive areas in the superior part of the upper trapezius and musculotendinous insertion of the pectoral muscle.

topographical pressure pain sensitivity maps of the Shoulder Region in individuals with subacromial pain syndrome
Manual Therapy, 2015Co-Authors: Ivana Leao Ribeiro, Pascal Madeleine, Cesar Fernandezdelaspenas, Paula R Camargo, Francisco Alburquerquesendin, Tania F SalviniAbstract:Background: Topographical pain maps (TPM) are useful tools to assess deep tissue sensitivity in musculoskeletal pain conditions. There is evidence suggesting bilateral sensitivity in subacromial pain syndrome (SAPS), although it is not widely accepted. No previous study has investigated TPM of the Shoulder in SAPS. Objective: To investigate whether differences for TPM of the Shoulder are evident among patients with unilateral SAPS and controls. Methods: Pressure pain thresholds (PPTs) were assessed 3 times at each point and there was a 20 s rest period between each one. The TPM were calculated using 29 pre-determined points on both Shoulders in all groups by inverse distance weighted interpolation of PPT data. Multivariate Analysis of Covariance was applied to detect differences in PPTs between groups, sides, points (gender as covariate). Results: The results revealed significant differences between points and genders (both, P < 0.001), but not between groups (P ¼ 0.243) and sides (P ¼ 0.812). Heterogeneous distribution of mechanical pain sensitivity was found in both groups as the PPTs were lower on the root spine of the scapula and the posterior border of the acromion (points 5e8, P < 0.05), glenohumeral joint (points 17e20, P < 0.01) and the anterior deltoid muscle (points 21e25, P < 0.001) compared to the average of the other sites on the Shoulder. Women exhibited bilateral lower PPTs in all points than men in both groups (all, P < 0.01). Conclusions: This study revealed no differences for mechanical pain sensitivity in patients with SAPS experiencing lower levels of pain compared with matched controls, but showed heterogeneous distribution of PPTs in the Shoulder.

a new method to diagnose neuromuscular disorders in the neck Shoulder Region
International Conference on NeuroRehabilitation ICNR, 2014Co-Authors: Steffen Vangsgaard, Ernst Albin Hansen, Pascal MadeleineAbstract:The H-reflex is often used in the clinic as a tool to test for cervical radiculopathy or other neurologic disorders. Additionally, it is often used experimentally to investigate neural changes at a segmental level following an intervention (e.g. strength training) (1). Methods for recording H-reflexes in the soleus and tibialis anterior muscles have been thoroughly tested. However, only few studies have assessed H-reflexes of the upper extremity (2).

on functional motor adaptations from the quantification of motor strategies to the prevention of musculoskeletal disorders in the neck Shoulder Region
Acta Physiologica, 2010Co-Authors: Pascal MadeleineAbstract:Background: Occupations characterized by a static low load and by repetitive actions show a high prevalence of work-related musculoskeletal disorders (WMSD) in the neck–Shoulder Region. Moreover, muscle fatigue and discomfort are reported to play a relevant initiating role in WMSD. Aims: To investigate relationships between altered sensory information, i.e. localized muscle fatigue, discomfort and pain and their associations to changes in motor control patterns. Materials & Methods: In total 101 subjects participated. Questionnaires, subjective assessments of perceived exertion and pain intensity as well as surface electromyography (SEMG), mechanomyography (MMG), force and kinematics recordings were performed. Results: Multi-channel SEMG and MMG revealed that the degree of heterogeneity of the trapezius muscle activation increased with fatigue. Further, the spatial organization of trapezius muscle activity changed in a dynamic manner during sustained contraction with acute experimental pain. A graduation of the motor changes in relation to the pain stage (acute, subchronic and chronic) and work experience were also found. The duration of the work task was shorter in presence of acute and chronic pain. Acute pain resulted in decreased activity of the painful muscle while in subchronic and chronic pain, a more static muscle activation was found. Posture and movement changed in the presence of neck–Shoulder pain. Larger and smaller sizes of arm and trunk movement variability were respectively found in acute pain and subchronic/chronic pain. The size and structure of kinematics variability decreased also in the Region of discomfort. Motor variability was higher in workers with high experience. Moreover, the pattern of activation of the upper trapezius muscle changed when receiving SEMG/MMG biofeedback during computer work. Discussion: SEMG and MMG changes underlie functional mechanisms for the maintenance of force during fatiguing contraction and acute pain that may lead to the widespread pain seen in WMSD. A lack of harmonious muscle recruitment/derecruitment may play a role in pain transition. Motor behavior changed in Shoulder pain conditions underlining that motor variability may play a role in the WMSD development as corroborated by the changes in kinematics variability seen with discomfort. This prognostic hypothesis was further, supported by the increased motor variability among workers with high experience. Conclusion: Quantitative assessments of the functional motor adaptations can be a way to benchmark the pain status and help to indentify signs indicating WMSD development. Motor variability is an important characteristic in ergonomic situations. Future studies will investigate the potential benefit of inducing motor variability in occupational settings.

accumulation of activated mast cells in the Shoulder Region of human coronary atheroma the predilection site of atheromatous rupture
Circulation, 1994Co-Authors: Maija Kaartinen, Antti Penttilä, Petri T. KovanenAbstract:BACKGROUNDRupture in the Shoulder Region of a coronary atheroma is considered to be a sequel to local extracellular matrix degradation in this highly vulnerable site. Such degradation could be triggered by mast cells, which are filled with neutral proteases and are present in coronary atheromas. However, the distribution and phenotype of mast cells within coronary atheromas have not been studied.METHODS AND RESULTSSpecimens of normal and atherosclerotic human coronary intima from 32 autopsy cases with ages ranging from 13 to 67 years were stained with monoclonal antibodies against the two major proteases of mast cells, tryptase and chymase. Of the tryptase-containing mast cells, a variable proportion (average, 40%; range, 0% to 100%) also contained chymase. In the normal coronary intimas, mast cells amounted to 0.1% of all nucleated cells. In the fatty streaks, this proportion was higher by 9-fold, and in the cap, core, and Shoulder Regions of atheromas by 5-, 5-, and 10-fold, respectively. Electron and l...

Mast cells of two types differing in neutral protease composition in the human aortic intima. Demonstration of tryptase- and tryptase/chymase-containing mast cells in normal intimas, fatty streaks, and the Shoulder Region of atheromas.
Arteriosclerosis Thrombosis and Vascular Biology, 1994Co-Authors: Maija Kaartinen, Antti Penttilä, Petri T. KovanenAbstract:Biochemical studies in vitro have demonstrated that stimulated mast cells induce macrophage foam cell formation through the synergistic action of mast cell granule neutral proteases and proteoglycans. To determine the presence and number of mast cells in human arterial intima, the site of atherogenesis, specimens of normal and atherosclerotic human aortic intima from 35 autopsies of persons ranging from 13 to 67 years old were stained with monoclonal antibodies against the two major proteases of mast cells, tryptase and chymase. All mast cells present were found to contain tryptase, and an average of 40% contained chymase as well. In sections of normal intimas, fatty streaks, and atheromas, the mast cells had average densities of 15/mm2, 15/mm2, and 3/mm2, respectively. In contrast to the normal intimas and fatty streaks, however, the atheromas had mast cells distributed unevenly in a typical pattern: 8/mm2 in the Shoulder Region, 1/mm2 in the fibrous cap, and none in the core Region. In normal intimas, fatty streaks, and the Shoulder Region of atheromas, the mast cells amounted to 3% of all nucleated cells. The ratios of mast cells to T lymphocytes and to macrophages, respectively, were 2:1 and 1:4 in normal intimas, 1:3 and 1:10 in fatty streaks, and 1:5 and 1:20 in the Shoulder Region of atheromas. Thus, among the blood-borne cells in the human aortic intima, mast cells compose a significant cell population, and in terms of their protease content, these intimal mast cells are heterogeneous.(ABSTRACT TRUNCATED AT 250 WORDS)

dynamic Shoulder dynamometry a way to develop delay onset muscle soreness in Shoulder muscles
Journal of Biomechanics, 2006Co-Authors: Pascal Madeleine, Hongling Nie, Lars ArendtnielsenAbstract:A dynamic Shoulder dynamometer has been designed to develop a vertical downward force over a measured range of motion, i.e. scapular elevation. The dynamometer is force-controlled to apply a required force within the range of motion. Calibration procedures were performed to assess the reliability of the force and displacement measurements. The system is designed to operate in isometric or eccentric conditions. For eccentric exercise the dynamometer has, for the first time, provided possibilities to elicit delay onset muscle soreness in Shoulder muscles. In future, the apparatus will enable investigations of sensory-motor interactions in the Shoulder Region.

delayed onset muscle soreness in neck Shoulder muscles
European Journal of Pain, 2005Co-Authors: Hongling Nie, Pascal Madeleine, Adam Kawczynski, Lars ArendtnielsenAbstract:Abstract The aim of the present study is to: (1) induce delayed onset muscle soreness (DOMS) in the neck and Shoulder muscles; (2) compare the pressure pain sensitivity of muscle belly with that of musculotendinous tissue after DOMS; (3) examine the gender differences in the development of DOMS. An eccentric Shoulder exercise was developed to induce DOMS on neck/Shoulder muscles using a specially designed dynamometer. Eccentric Shoulder contraction consisted of 5 bouts, each bout lasted 3 min, with 3 min rest period between each bout. The right Shoulder was elevating against a downward pressure force of 110% maximal voluntary contraction force exerted by the dynamometer. Pressure pain thresholds (PPT) of 11 sites (seven sites measured were muscle belly and four sites were myotendinous area) on neck/Shoulder Region were measured before, immediately after, 24 and 48 h after exercise. Pain intensity, pain area and index of McGill pain questionnaire were assessed and all were increased after exercise. DOMS was induced in the Shoulder muscles. PPT was significantly decreased and reached lowest values at 24 h. The muscle belly sites are more sensitive to pain than the musculotendinous sites. No gender differences were found in any of the parameters used to assess the development of DOMS. DOMS did not distribute evenly in the neck/Shoulder Region. Soreness after exercise in the neck and Shoulder seems not to be among the conditions that produce predominant musculoskeletal pain in females.

is diversity of leisure time sport activities associated with low back and neck Shoulder Region pain a finnish twin cohort study
Preventive medicine reports, 2019Co-Authors: Sara Kaartinen, Urho M Kujala, Marja Mikkelsson, Sari Aaltonen, Tellervo Korhonen, Antti Latvala, Jaakko KaprioAbstract:Abstract This study investigates cross-sectional and longitudinal associations between the diversity of leisure-time sport activities and the frequencies of low back pain (LBP) and neck-Shoulder Region pain (NSP) in twins, including a cross-sectional within-pair design to adjust for potential familial confounding. Finnish twins born in 1975–79 (FinnTwin16 study) reported participation in leisure-time sport activities at the mean ages of 17 (1992–96) (n = 5096, 54% females) and 34 years (2010−12) (n = 3731, 57% females). Diversity assessed as the number of sport activities was categorized as 1, 2, 3, 4, and ≥ 5, excluding inactive individuals. The frequencies of LBP (n = 3201) and NSP (n = 3207), reported at age 34, were categorized as never/seldom, monthly, or weekly pain. Cross-sectional and longitudinal individual-based associations between the number of sport activities and the frequency of LBP and NSP were investigated with multinomial logistic regression analyses, adjusting for multiple confounders. Cross-sectionally, participation in ≥5 sport activities, compared to 1 sport, was associated with significantly less weekly LBP (OR = 0.63, 95%CI = 0.43–0.90), but not with NSP. Longitudinally, participation in several sport activities in adolescence had no significant association with LBP or NSP in adulthood. Cross-sectional within-pair analyses were conducted among twin pairs discordant for LBP (n = 507) and NSP (n = 579). The associations between monozygotic and dizygotic twin pairs were similar in LBP-discordant pairs but differed within NSP-discordant pairs. Participation in ≥5 sport activities in adulthood may be associated with less weekly LBP, but not with monthly LBP or the frequency of NSP. However, within-pair analyses for NSP suggest confounding due to shared familial factors.

cumulative incidence of Shoulder Region tendon injuries in male former elite athletes
International Journal of Sports Medicine, 2011Co-Authors: Jyrki Kettunen, Urho M Kujala, Seppo Sarna, Jaakko KaprioAbstract:Some types of sports are thought to include a high risk for Shoulder Region tendon injuries but little data exist on long-term cumulative incidence of these injuries. The aim of our study was to investigate Shoulder Region tendon injuries diagnosed by physicians in former elite male athletes participating in sports including maximal overhead manoeuvres (overhead athletes) and also other athletes before the age of 45 years and within the subjects' lifetime, compared to control subjects. A postal questionnaire was sent in 2002 to male former elite athletes (n=785; mean age 68 years when responding to the questionnaire; overhead athletes n=111, others n=674) and control subjects (n=416; mean age 67 years). Overhead athletes had a higher risk for Shoulder Region tendinopathy before the age of 45 (adjusted odds ratio (OR) 4.1, 95% confidence interval (CI) 2.0-8.4, p Language: en
