A histological, biological, and immunohisto-chemical study of human lumbar ligamentum flavum.To analyze changes in the hypertrophied flavum clarify their etiology.Hypertrophy has been considered a major contributor to development spinal canal stenosis (LSCS). Although previous studies have reported some factors related hypertrophy, its etiology is still unclear.Ligamentum samples were collected from 20 patients with LSCS (LSCS group) 10 disc herniation (LDH as control. The thickness was...
Arthroscopic pancapsular release has been recommended for recalcitrant frozen shoulder, but regaining range of motion not sufficient compared with the unaffected side. There is no consensus about reasons these remaining restrictions in motion, residual capsular or connective tissue must be considered a candidate. A thickened coracohumeral ligament at rotator interval reported as one most specific manifestations shoulder. It covers wider portions subscapularis tendon, supraspinatus and...
Elbow or shoulder injuries are common in overhead sports. Because energy derived from the lower extremity passes through trunk to upper motion, a break such kinetic chain could lead arm injuries. However, there is only limited information about role of and support preventing elbow This study aimed explore association pain with elbow/shoulder among young athletes. We conducted cross-sectional using self-reported questionnaires mailed athletes belonging Miyagi Amateur Sports Association. The...
Contraction of cultured myotubes with application electric pulse stimulation (EPS) has been utilized for investigating cellular responses associated actual contractile activity. However, derived from human subjects often exhibit relatively poor EPS-evoked activity, resulting in minimal contraction-inducible (i.e. myokine secretion). We herein describe an "in vitro exercise model", using hybrid comprised myoblasts and murine C2C12 myoblasts, exhibiting vigorous activity response to EPS....
Sporadic inclusion body myositis (sIBM) is the most common idiopathic inflammatory myopathy, and several reports have suggested that mitochondrial abnormalities are involved in its etiology. We recruited 9 sIBM patients found significant histological changes an elevation of growth differential factor 15 (GDF15), a marker disease, strongly suggesting involvement dysfunction. Bioenergetic analysis patient myoblasts revealed impaired function. Decreased ATP production, reduced size dynamics...
Skeletal muscle regeneration after injury is a complex process involving interactions between inflammatory microenvironments and satellite cells. Interleukin (IL)-1 key mediator of responses exerts pleiotropic impacts on various cell types. Thus, we aimed to investigate the role IL-1 during skeletal regeneration. We herein show that IL-1α/β-double knockout (IL-1KO) mice exhibit delayed cardiotoxin (CTX) injection, characterized by infiltrations immune cells accompanied suppressed local...
Metabolic immunomodulation involving IL-1 has been investigated for unfavorable metabolic effects, including obesity, but a potentially favorable role remains unclear. Here, we find mechanistic interactions between working skeletal muscles and locally recruited neutrophils expressing IL-1β, which supports muscle performance through priming exercise-dependent GLUT4 translocation. Thus, during exercise, both IL-1α/β-deficient neutrophil-depleted mice similarly exhibit increased fatigability...
A thickened coracohumeral ligament is a highly specific manifestation of, and primary restraint against external rotation in frozen shoulders.The purpose of this study was to evaluate the effects complete arthroscopic release on range motion shoulder.Fifty-two consecutive shoulders 52 patients were treated between April 2015 June 2016. To solely glenohumeral motion, scapula fixed by an examiner with one hand (without palpating scapular motion), measured using goniometer. For first step,...
Elastic fibers and proteoglycans are major components of the extracellular matrix their changes have been reported in some pathological conditions. Further, recent studies indicated that glycosaminoglycans inhibit elastic fiber assembly. The purpose this study was to investigate ligamentum flavum analyze relationships thickening from lumbar spinal canal stenosis (LSCS). Ligamentum samples were collected 20 patients with LSCS (thickened group) 10 disc herniation (non-thickened as a control....
This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic frozen shoulder and diabetic secondary (diabetic shoulder).Forty-four shoulders 10 failed conservative treatment for at least 3 months were included this study. The was performed visual analogue scale, range motion, Constant scores measured before last follow-up examination.No major complications observed during procedure. Sufficient improvement not...
Sleep disturbance is a common symptom after natural disasters. Although musculoskeletal pain also increases disasters, its relation to sleep not clear. The purpose of this study was determine the influence on new-onset among survivors Great East Japan Earthquake (GEJE). A prospective cohort conducted with GEJE at two and three years earthquake. New-onset defined as absent present sites included low back, shoulder, knee, hand or foot. number earthquake divided into categories (0, 1, 2 more)....
Muscle pain is a common condition that relates to various pathologies. overuse induces muscle pain, and neutrophils are key players in production. Neutrophils also play central role chronic by secreting interleukin (IL)-18. The aim of this study was investigate the involvement IL-18 mouse model pain. right hind leg muscles BALB/c mice were stimulated electrically induce excessive contraction. left not stimulated. pressure threshold, number neutrophils, levels investigated. Furthermore,...
Verbal or physical abuse from coaches has a negative impact on young athletes.To prevent against athletes, it is important to know the characteristics of abusive coaches.This study aimed elucidate who commit verbal in youth sports teams.A cross-sectional was conducted with sport teams Miyagi prefecture, Japan (n = 1,283), using self-reported questionnaire (response rate 24.0%).Multivariate logistic regression models were used for analyses.The prevalence and towards athletes 64.7% 830) 6.2%...
Lower back pain (LBP) is a common health problem after natural disasters. Although some related factors have been reported, the effect of sleep disturbances on LBP not clear. The purpose this study was to elucidate influence Great East Japan earthquake (GEJE). A panel conducted with survivors GEJE (n = 2,295) at three and four years disaster using self-reported questionnaires. changes in presence during two periods were assessed; characterized as either new onset or continuation LBP....
Adhesive capsulitis of the shoulder (also known as frozen shoulder) is a painful and disabling disorder with an estimated prevalence ranging from 2% to 5% in general population. Although precise pathogenesis unclear, thickened capsule coracohumeral ligament (CHL) have been documented be one most specific manifestations. The CHL has understood limit external rotation shoulder, restriction internal believed related posterior capsular tightness. In this paper, three cases refractory treated...
