Addressing post-COVID-19 musculoskeletal symptoms through telemedicine: A study protocol

Objective: The purpose of the study will be to evaluate the effect of a rehabilitation program on the improvement of patients with post-COVID-19 musculoskeletal symptoms, as well as to quantify the impact of telemedicine that evaluates the evolution of pain, functionality, and quality of life. Methods: We will carry out a case-control study in post-COVID-19 musculoskeletal symptoms patients who will undergo a multicomponent rehabilitation program, together with an intervention and a follow-up using programmed telemedicine sessions. Data will be collected on the improvement of functional capacity and quality of life, in addition to assessing the evolution of musculoskeletal symptomatology, as well as pain and psychological variables. The telemedicine sessions will improve user adherence and follow-up, and the results are expected to be disseminated to the scientific community during and after the end of the study

Identifying Clinical and MRI Characteristics Associated with Quality of Life in Patients with Anterior Cruciate Ligament Injury:Prognostic Factors for Long-Term

Background: Associated lesions in the diagnostic MRI may be related to worse long-term subjective outcomes. There is a lack of conclusive information about the long-term outcomes of associated injuries in anterior cruciate ligament (ACL) tears. The purpose of this study is to assess the long-term effects of associated injuries in ACL tears measured by means of a quality of life (QOL) assessment. Methods: A retrospective cohort study of 225 consecutive patients admitted for physical therapy with ACL injury (42 ± 12 years, 28.2% female) were conducted. All demographic and clinical variables were used to measure a QOL. Univariate and multivariable analyses were completed. Results: The mean follow-up period was 8.4 ± 2.6 years. In univariate analysis, male gender, and sports as the cause of the ACL lesion were factors significantly associated with improved International Knee Documentation Committee (IKDC) scores at the end of follow-up (all p < 0.002). In multivariable analysis, the occurrence of bone contusion was positively associated with injury (OR = 2.12) and negatively associated with sports injury (OR = 0.44) and medial collateral ligament (MCL) injury (OR = 0.48). Conclusions: After ACL injury, male gender and sports injury were associated with better clinical outcomes

Efecto de tratamiento térmico en aleaciones feal1% at li expuestas a pruebas de oxidación en diferentes temperaturas

La adición de Li en aleaciones intermetalicas base Fe3Al ayuda en la mejora de propiedades mecánicas y resistencia a la corrosión. Las aleaciones se producen con técnicas convencionales de vaciado usando crisoles de SiC y se someten a un tratamiento térmico de 400ºC por 144h. Se realizaron pruebas de oxidación de alta temperatura en termobalanza con atmósfera estática a temperaturas de 650, 800 y 900 ºC las cuales indicaron una diferencia en la cinética de oxidación entre las muestras con tratamiento térmico y sin el. Por análisis de Microscopía electrónica de barrido se pudo ver que la capa de oxidación es más uniforme cuando se tiene tratamiento térmico

Empleo de sensores electroquímico para determinación de velocidad de corrosion in-situ en pozos de agua

Se justifica el uso de la técnica electroquímica de Rp como una alternativa para ser empleada en monitoreos de agua de pozo in situ con la finalidad de determinar la cinética de corrosión; proporcionándose una metodología para oder realizar monitoreos mediante celdas electroquímicas. Puesto que la técnica tradicional para poder llevar a cabo estos estudios es la prueba gravimétrica se expusieron cupones en el interior del pozo de agua durante un año. Una vez concluida la exposición de dichos cupones se compararon los resultados obtenidos con la técnica gravimétrica con los resultados obtenidos mediante la técnica de Rp

Efficacy of Manual Therapy on Facilitatory Nociception and Endogenous Pain Modulation in Older Adults with Knee Osteoarthritis: A Case Series.

Background: manual therapy (MT) has been shown to have positive effects in patients with osteoarthritis (OA)-related pain, and its use in clinical settings is recommended. However, the mechanisms of action for how these positive effects occur are not yet well understood. The aim of the present study was to investigate the influence of MT treatment on facilitatory nociception and endogenous pain modulation in patients with knee OA related pain. Methods: Twenty-eight patients with knee OA were included in this study. Pain intensity using the numerical pain rating scale (NPRS), temporal summation (TS), conditioned pain modulation (CPM), and local (knee) and distant (elbow) hyperalgesia through the pressure pain threshold (PPT), were assessed to evaluate the pain modulatory system. Patients underwent four sessions of MT treatments within 3 weeks and were evaluated at the baseline, after the first session and after the fourth session. Results: the MT treatment reduced knee pain after the first session (p = 0.03) and after the fourth session (p = 0.04). TS decreased significantly after the fourth session of MT (p = 0.02), while a significant increase in the CPM assessment was detected after the fourth session (p = 0.05). No significant changes in the PPT over the knee and elbow were found in the follow-ups. Conclusions: The results from our study suggest that MT might be an effective and safe method for improving pain and for decreasing temporal summation.post-print502 K
