Misinformation and Impact on Interprofessional Healthcare Students' Knowledge, Attitudes, Perceptions, and Concerns of COVID-19.

BACKGROUND: The COVID-19 pandemic has highlighted the importance of information sources (e.g., Internet, social media) and their role in spreading misinformation. PURPOSE: To describe the information sources and frequency of use by health professional students and to compare users of dependable and nontrustworthy news sources on stressors, stress relievers, safety, and preventative activities, worries, and attitudes toward COVID-19. METHODS: 123 students from nursing (38%), medicine (33%), and health professions (28%) completed online surveys on disaster preparedness training, knowledge of the COVID-19 virus, and safety and prevention practices. Students were mostly female (81%), white (59%), and aged 21-30 yrs (72%). RESULTS: Students who relied on credible news sources scored higher on knowledge of the COVID-19 condition and reported less stress than their counterparts. CONCLUSION: The findings emphasize the importance of students avoiding untrustworthy news sources. Informed students are less stressed and can help initiate necessary safety measures in the areas they serve.

THE EFFECTS OF POSTERIOR TIBIAL MOBILIZATION ON MENISCAL MOVEMENT: AN IN-SITU INVESTIGATION.

BACKGROUND: Anterior knee pain during knee extension may be related to a meniscal movement restriction and increased meniscal load during function. One method of treatment involves the use of manual posterior mobilization of the tibia to specifically target the meniscotibial interface of the knee joint. PURPOSE: The purpose of this study was to measure motion at a cadaveric medial meniscus anterior horn during a posterior tibial mobilization. STUDY DESIGN: Prospective, multifactorial, repeated-measures laboratory study. METHODS: Eight unembalmed cadaveric knee specimens were mounted in a custom apparatus and markers were placed in the medial meniscus, tibia and femur. The tibia was posteriorly mobilized in two randomized knee positions (0 degrees and 25 degrees) using three randomly assigned loads (44.48N, 88.96N, and 177.93N). Markers were photographed and digitally measured and analyzed. RESULTS: All load x position conditions produced anterior displacement of the meniscus on the tibia, where the displacement was significant [t (7) = -3.299; p = 0.013] at 0 degrees loaded with 177.93N (mean 0.41 ± 0.35 mm). The results of 2(position) x 3(load) repeated measures ANOVA for meniscotibial displacement produced no significant main effects for load [F (2,14) = 2.542; p = 0.114) or position [F (1,7) = 0.324, p = 0.587]. All load x position conditions produced significant posterior tibial and meniscal displacement on the femur. The 2(position) x 3(load) repeated measures ANOVA revealed a significant main effect for load for both femoral marker displacement relative to the tibial axis [F (2,14) = 77.994; p < 0.001] and meniscal marker displacement relative to the femoral marker [F (2,14) = 83.620; p < 0.001]. CONCLUSION: Use of a mobilization technique to target the meniscotibial interface appears to move the meniscus anteriorly on the tibia. It appears that this technique may be most effective at the end range position. LEVEL OF EVIDENCE: 2 (laboratory study).
