Prevalence of positive modified scapular assistance test in patients with shoulder pain with and without scapular dyskinesis: a cross-sectional study.

BACKGROUND: Scapular dyskinesis (SD) is defined as an altered position of the scapula or altered motion patterns and their relationship with shoulder pain (SP) is still under debate. The modified scapular assistance test (mSAT) modifies scapular kinematics and is used to determine the impact of scapular dyskinesis in shoulder pain. However, data about the relationship between SD and the result of mSAT is scarce. PURPOSE: The aim of this study is to establish the frequency of positive mSAT in patients with SP and compare the prevalence in those with and without SD. As a secondary objective, we compare changes in pain intensity during the mSAT in patients with a positive test between those with and without SD. STUDY DESIGN: Cross-sectional study. METHODS: Adult patients with a diagnosis of SP and with pain ≥2 during anterior flexion were included. The mSAT, scapular dyskinesis test (SDT), and shoulder function were assessed. RESULTS: The study was conducted between August 2018 and May 2022 and included 70 patients. The prevalence of SDT was 54.29%. No statistically significant associations were detected when assessing the relation between the presence of mSAT and SDT (p-value 0.83). When comparing pain response during the mSAT in patients with a positive test, no differences were seen between patients with SD and patients without SD (p-value 0.26). CONCLUSIONS: The prevalence of positive mSAT results was equal between individuals with and without SD. These findings suggest that the presence or absence of SD in individuals with SP was independent of the mSAT result. The mSAT should not be used solely for the assessment of SD in clinical practice nor be influenced by the SDT result. More research is needed to determine if the result of this test could inform prognosis and guide treatment choices.

Standard measurement error and minimal detectable change of the Back-PAQ ArgSpan questionnaire: Secondary analysis.

BACKGROUND: Negative attitudes and beliefs about back pain in patients with low back pain (LBP) are associated with high levels of pain and negatively influence clinical outcome. The Back Pain Attitudes Questionnaire (Back-PAQ) was developed to assess back beliefs of patients and healthcare professionals. The minimal detectable change (MDC) is defined as the smallest amount of change that can be detected not due to inherent variation or "noise" in the measure. The MDC values at 68%, 90% and 95% confidence levels of the Back-PAQ ArgSpan are unknown. OBJECTIVE: to calculate standard error measurement (SEM) and MDC to confirm the feasibility of Back-PAQ ArgSpan as a reliable outcome measure in clinical and research settings. STUDY DESIGN: a secondary analysis was carried out using a subgroup of data from the cross-cultural adaptation and validation of the Argentine version of the Back PAQ. METHOD: SEM was calculated (SD × âˆš1 - ICC) and MDC as (SEM × z-value × âˆš2). MDC was calculated as percentage as well. RESULTS: the SEM was 5.16 points. The MDC68, MDC90 and MDC95 of the Back-PAQ were 7.30, 12 and 14.3 points, respectively. The percentages of MDC68, MDC90 and MDC95 of the Back-PAQ were 6.7%, 11.0% and 13.1%, respectively. CONCLUSION: The present study demonstrated that the Back-PAQ ArgSpan is a reliable and interpretable measurement tool. When assessing a patient, a change in the score in the Back-PAQ ArgSpan over 15 points shows a true change at 95% confidence level.

Spanish translation, cross-cultural adaptation and validation of the Argentine version of the Back Pain Attitudes Questionnaire.

BACKGROUND: low back pain (LBP) is the main cause of years lived with disability worldwide. Psychosocial factors have been shown to be good predictors of persistent LBP. Within these, unhelpful beliefs about the back seem to be important in the development and chronicity of the symptoms. The Back Pain Attitudes Questionnaire (Back-PAQ) is an instrument that explores beliefs about the back that has been validated for people with and without back pain and healthcare professionals. However, until now, it has not been translated and validated for the Argentine population. OBJECTIVE: translate into Spanish, cross-cultural adapt and validate the Back-PAQ for the Argentine population with and without back pain. STUDY DESIGN: study of diagnostic accuracy/assessment scale. METHODS: the study was carried out in three consecutive phases: translation, cross-cultural adaptation and validation. We included Argentinians aged 18 years or more. We used the Back-PAQ, modified Fear Avoidance Beliefs Questionnaire (mFABQ) and the Global Rating of Change (GROC) scale to assess the psychometric properties. RESULTS: three hundred and seventy-two participants were included for the analysis. The time taken to answer and score the questionnaire was 5.6 and 1.6 min, respectively. Neither a ceiling nor a floor effect was observed. Internal consistency was 0.76. One hundred and eighty-six participants were considered stable. Test-retest reliability was 0.90. A weak correlation (0.33) was found between the Back-PAQ and the mFABQ. CONCLUSION: the Argentine version of the Back-PAQ is a viable, reliable and valid tool for the assessment of the back beliefs of the Argentine population.

Entrenamiento con restricción al flujo sanguíneo / Blood flow restriction training

RESUMEN El entrenamiento con restricción al flujo sanguíneo es un método de entrenamiento que implica la aplicación de un dispositivo de envoltura próxima al músculo a entrenar, y realizar repeticiones con cargas inferiores a las recomendadas tradicionalmente para lograr hipertrofia y el aumento de fuerza muscular. Este entrenamiento ha ganado popularidad dentro de la kinesiología gracias a que permite alcanzar dichos objetivos en pacientes donde no es posible realizar cargas mayores debido a su condición clínica. El objetivo de este paso a paso es describir el procedimiento para su aplicación y detallar las contraindicaciones que presenta la técnica.

ABSTRACT Blood-flow restriction training is a training technique that involves the application of a blood pressure cuff proximally to the muscle that is being trained and low-load training to elicit hypertrophy and increase muscle strength. This training technique has become popular among physical therapists, since both goals are attainable in patients unable to do high-load training due to their clínical condition. This study aims to describe the procedure of this technique and detail any contraindications.

Creencias y actitudes de los atletas sobre el dolor lumbar. Estudio transversal, tipo encuesta / Athletes' beliefs and attitudes about low back pain. A cross-sectional survey

RESUMEN Objetivo: Identificar las creencias de los deportistas acerca del dolor lumbar. Como objetivo secundario, proponemos averiguar si las creencias reportadas difieren según la experiencia del dolor lumbar. Materiales y método: Estudio transversal tipo encuesta. Se invitó a atletas (recreacionales, amateurs y profesionales), mayores de 18 años con o sin dolor lumbar, a participar de una encuesta online a través de las redes sociales. Se utilizó el cuestionario Back Pain Attitudes Questionnaire (Back-PAQ) para evaluar las creencias sobre la espalda. Las opciones de las preguntas del Back-PAQ fueron clasificadas como "positivas", "neutras" o "negativas". Resultados: Un total de 1591 respuestas fueron incluidas en el análisis. La media del puntaje total del Back-PAQ fue 113,1 (Intervalo de Confianza 95%, 112,5 - 113,7) con un puntaje mínimo de 63 y máximo de 148. No se encontraron diferencias estadísticamente significativas entre los grupos observados (p= 0,51). Los atletas con dolor actual tuvieron creencias menos útiles que aquellos con historia de dolor lumbar: mediana de 115 (rango intercuartílico 108 - 121) versus 113 (rango intercuartílico 105 - 120); p= 0,002. Conclusión: Los atletas presentaron creencias predominantemente negativas sobre el dolor de espalda, independientemente del nivel de competencia. Prevalecieron los conceptos erróneos sobre la vulnerabilidad de la espalda y la necesidad de protegerla. Se expresaron creencias positivas sobre el pronóstico de un episodio de dolor lumbar.

ABSTRACT Objective: To identify athletes' beliefs and attitudes about low back pain (LBP) and, as a secondary objective, to determine whether these beliefs vary based on their LBP experience. Materials and method: A cross-sectional survey. Athletes (recreational, amateur, and professional) aged over 18 years with or without LBP were invited to participate in an online survey via social media. The Back Pain Attitudes Questionnaire (Back-PAQ) was used to evaluate their back beliefs. Back-PAQ items were classified into helpful, neutral, and unhelpful. Results: A total of 1591 responses were included in the analysis. The mean Back-PAQ total score was 113.1 (95% CI, 112.5 - 113.7), with a minimum score of 63 and a maximum score of 148. No statistically significant differences were observed between groups (p = 0.51). Athletes with current pain had more unhelpful beliefs than athletes with a LBP history: a mean of 115 (IQR 108 - 121) versus 113 (IQR 105 - 120); (p=0.002). Conclusion: Athletes had predominantly unhelpful beliefs about back pain, regardless of their level of competition. Misconceptions about the back being vulnerable and in need of protection were prevalent. Helpful beliefs about the prognosis of a LBP episode were identified.
