Adaptación transcultural, validación y valoración de las propiedades psicométricas, de la versión española del cuestionario Western Ontario Shoulder Instability Index / Transcultural adaptation, validation and assessment of the psychometric properties of the spanish version of the Western Ontario Shoulder Instability Index questionnaire

Objetivo. El propósito del presente trabajo es presentar la adaptación transcultural y validación realizada del cuestionario Western Ontario Shoulder Instability Index (WOSI) al idioma español (España), así como la evaluación de sus propiedades psicométricas. Material y métodos. La adaptación transcultural se realizó mediante la técnica de traducción y retrotraducción. Posteriormente se realizó una prueba piloto y se ponderaron las propiedades psicométricas. Se evaluaron 79 pacientes que cumplimentaron el cuestionario Western Ontario Shoulder Instability Index dos veces, en el periodo de 2 meses y se estratificaron estadísticamente en 3 grupos diferentes (cohortes). Resultados. • Validez estructural: ofreció un resultado válido, aunque dispar de la estructura de 4 dominios del cuestionario original. • Validez de criterio: Coeficiente de Correlación de Pearson: 0,745 (ROWE) y 0,471 (EQ-5D-5L). • Consistencia interna: alfa de Cronbach: 0,96, test-retest (ICC): 0,949. • Sensibilidad al cambio: t-Student: 42,38; respuesta promedio estandarizada (SRM): 2,69; tamaño del efecto (ES): 2,61; error estándar de medición (SEM): 23%; mínimo cambio detectable (SDC): 76%. No se halló efecto suelo o techo. Conclusiones. La versión española del cuestionario Western Ontario Shoulder Instability Index ofrece una herramienta válida, confiable y con una alta sensibilidad al cambio para la valoración de pacientes afectos de inestabilidad de hombro (AU)

Objective. The aim of the present study is to present a transcultural adaptation and validation of the Western Ontario Shoulder Instability Index questionnaire into Spanish (Spain), and to assess its psychometric properties. Material and methods. The transcultural adaptation was conducted according to sequential forward and backward translation approach. A pilot study was subsequently performed to ensure acceptable psychometric properties. The Western Ontario Shoulder Instability Index questionnaire was administered to 79 patients twice within a period of 2 months, and patients were stratified into 3 groups (cohorts). Results. • Structural validation: valid, though uneven results were obtained regarding the structure of the 4 domains of the original questionnaire. • Criterion validity: Pearson's correlation coefficient: ROWE:0.74; EQ-5D-5L:0.471. • Internal consistency: Cronbach's alpha: 0.96; coefficient of intraclass correlation: 0.949. • Sensitivity to change: t-Student- t: 42.38; standard response means: 2.69; effect size: 2.61; standard error of measurement: 23%; Minimal detectable change: 76%. No floor or ceiling effects were detected. Conclusions. The Spanish version of the Western Ontario Shoulder Instability Index questionnaire is a valid, reliable tool, and highly sensitive to change to assess patients with shoulder instability (AU)

Orofacial problems in musicians: a review of the literature.

OBJECTIVE: The objective of our study was to review the different pathologies of the stomatognathic system that can present in musicians as a result of playing their instruments. DESIGN: The National Library of Medicine's PubMed database was searched to identify all peer-reviewed articles in the English literature dealing with orofacial problems in musicians, using both subject headings such as MeSH terms (PubMed) and free text words in combination (oral, musician, violin, wind instruments, vocalists, orthodontic, tooth, temporomandibular disorders [TMD]). The identified studies were assessed independently by two authors. We included any instruments that involved the orofacial area: i.e., wind and brass instruments, vocalists, and violins and violas. RESULTS: Thirty-two articles were selected that were of many different types (clinical reviews, longitudinal and transverse studies of therapeutic procedures, case-control studies). Among orofacial problems, the most common disorders that affect musicians are TMDs, herpes simplex virus infections, orthodontic problems, and problems with perioral musculature. CONCLUSIONS: Musicians may suffer from pathological conditions that are worsened by their occupation due to excessive practice and stress. These conditions can cause permanent injuries that subsequently prevent the musicians from playing. Depending on the characteristics of the musical instrument and the way it is played, professional musicians generally show a propensity for buccodental problems.

Prevalence of temporomandibular disorder-related findings in violinists compared with control subjects.

OBJECTIVE: The aim of this study was to determine if there is an association between violin playing and the presence of signs and symptoms of temporomandibular disorder (TMD). STUDY DESIGN: We studied a group of violinists in the Murcia region of Spain, who were examined for TMD. The results were compared with those from a random control group who did not play any musical instrument. The groups were matched by age and gender. Statistical analysis was carried out using SPSS 15.0 statistical software. RESULTS: Compared with the control subjects, the violinists as a group had significantly more pain in maximum mouth opening (P < .005), parafunctional habits (P = .001), and occurrence of temporomandibular joint sounds (P < .005) as determined by chi-squared. CONCLUSIONS: Violin playing appears to be a factor associated with TMD-related findings.

Clinical anatomy of the arterial supply of the human patellar ligament.

The arterial supply of the human patellar ligament has been systematized on 20 knee joints. After intravascular injection of colored natural latex, the blood supply to the extensor apparatus of the knee was studied by anatomical dissection and tissue transparentation techniques. Three arterial pedicles (superior, middle and inferior) were observed placed on each side of the patellar ligament. Medial pedicles had their origin from the descending and the inferior medial genicular arteries. The lateral pedicles took their origin from the lateral genicular arteries and the recurrent tibial anterior artery. Two main vascular arches anastomosed with these pedicles: the retropatellar and the supratubercular. Both arterial pedicles and anastomotic arches gave rise to a peritendinous network, characterized by a high vascular density next to poles of the patellar ligament. Only the anastomotic arches gave rise to collateral vessels that pierced the tendon, which revealed two vascular segments in the arterial supply of the patellar ligament (bipolar pattern). The upper segment was supplied by deep vessels from the retropatellar arch, whereas the inferior segment received superficial vessels from collaterals of the supratubercular arch. These intratendinous vessels anastomosed in the middle third of the patellar ligament.
