    Background: Prehabilitation is a novel clinical strategy to optimize patients’ health in the waiting period before surgery. Objectives: This article aims to gather the evidence for the effectiveness of unimodal, non-pharmacological psychological prehabilitation interventions on preoperative anxiety and stress before surgery. Design: This is a PRISMA-guided systematic review and narrative synthesis of randomized controlled trials. Methods: The online databases Medline, Embase, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, PsycINFO and Google Scholar were searched on March 20th 2023. The search strategy led to 13,667 records screened and five records of randomized controlled trials included for full-text analysis. A risk-of-bias assessment was performed using the Revised Cochrane Risk of Bias 2 tool. Results: Significant reduction in preoperative anxiety was seen in three studies comprising 337 participants. Two studies did not find that unimodal psychological prehabilitation reduces preoperative anxiety. Only one study assessed preoperative stress and reported a significant reduction. Intervention types used included guided imagery, stress management training, virtual reality experience and computer cognitive behavioral therapy. Conclusions: There is contradictory evidence whether unimodal, non-pharmacological psychological prehabilitation can reduce preoperative anxiety. There is little evidence that non-pharmacological prehabilitation can reduce preoperative stress. Suggestions to improve the research in this field are discussed.</p

    Application of the Coupling Angle to Investigate Upper Limb Interjoint Coordination After Stroke

    Objective: Interjoint coordination after stroke is affected, which limits the use of the upper limb. Current methods to determine interjoint coordination lack the ability to visualize and quantify the movement. Therefore we investigated if the coupling angle can be used to visualize and interpret upper limb interjoint coordination following a stroke. Methods: Seven chronic stroke patients trained six weeks with an assistive home-training system (MERLIN). Kinematic outcomes, i.e. elbow and shoulder range of motion, movement duration, and angle-angle plots were determined in a retrieving task. Interjoint coordination between elbow flexion and shoulder abduction angles was expressed as the coupling angle phases and the number of phase transitions: proximal/distal joint leading phase, in-phase and anti-phase. Comparisons were made within sides: pre-test versus post-test, and between sides: most-affected (MA) versus least-affected (LA). Results: Smaller elbow flexion angles were found PreMA versus PreLA, and smaller shoulder abduction angles in PostMA versus PostLA. A general coordination pattern was revealed on the LA side, but not on the MA side. A trend showed less phase transitions at the MA side after training, suggesting a smoother movement. Quantification of the movement phases indicated more involvement of the shoulder joint involvement in the MA side during pre-test. After training, these differences were not apparent, which might reveal an increased independent control of the elbow joint. Conclusions: The coupling angle and the movement phases provide a promising tool to investigate post-stroke interjoint coordination patterns. Significance: A new visualisation of the interjoint coordination may benefit rehabilitation of stroke survivors. Registration: This trial was registered at the Netherlands Trial Register (NL7535) https://www.trialregister.nl/trial/7535.</p

    Water bottle flipping physics

    The water bottle flipping challenge consists of spinning a bottle, partially filled with water, and making it land upright. It is quite a striking phenomenon, since at first sight, it appears rather improbable that a tall rotating bottle could make such a stable landing. Here, we analyze the physics behind the water bottle flip, based on experiments and an analytical model that can be used in the classroom. Our measurements show that the angular velocity of the bottle decreases dramatically, enabling a nearly vertical descent and a successful landing. The reduced rotation is due to an increase in the moment of inertia, caused by the in-flight redistribution of the water mass along the bottle. Experimental and analytical results are compared quantitatively, and we demonstrate how to optimize the chances for a successful landing.</p

    Letter from the Citizens of Ommen to the Governor of Overijssel

    Sixteen citizens of Ommen sent a communication to the Governor of the Province that they saw no need for him to send a military detachment to Ommen now that the disturbances had ended. Besides, a relatively few people were the troublemakers. The billeting of military people will be a great burden to the citizens of Ommen.https://digitalcommons.hope.edu/vrp_1830s/1048/thumbnail.jp
