In France, the padding placed on these obstacles conforms to a design standard to assess its ability to dissipate energy when impacted by a skier/snowboarder. Padding performance, i.e. its ability to prevent or mitigate injuries and the changes in performance over time remain poorly understood. Considering the global objective to explore the padding's ability to protect from injuries during its cycle of use, a large experimental campaign was designed to investigate various padding performance.</p></div><div><h3>Design</h3><p>Experimental drop tests were performed on padding in ski areas using instrumented head and trunk impactors.</p></div><div><h3>Method</h3><p>The influences of the padding's properties (thickness, age, impact location, cover), environment (temperature, position on the obstacle) and impact conditions (speed, impactor) on head and chest accelerations were investigated. 180 drop tests were performed on 40 padding samples (with thicknesses ranging from 10 cm to 30 cm) with ages varying from 0 to 17 years old.</p></div><div><h3>Results</h3><p>This study showed a significant influence of speed, impactor and the padding's thickness (<em>P</em> < 0.001) and also position.

It is very important to differentiate between uneducated scepticism (e.g. the anti-vaccination movement) where valuable areas of medicine are disputed and well-informed scepticism, where legitimate experts reveal flaws in mainstream medicine. It is assumed that medicine being a science will be self-correcting and inevitably move towards a stronger evidence-base, but a competing factor is the profit motive. Three excellent books are reviewed, all Australian and all covering primarily musculoskeletal medicine (<em>Back Up</em> by Mannix; <em>Surgery: The Ultimate Placebo</em> and <em>Hippocrasy</em> by Harris and Buchbinder). These texts reveal that musculoskeletal medicine has many treatments where the desire to offer hope and, also, make a profit is taking precedence over scientific evidence. Because many healthcare presentations of young people are musculoskeletal, doctors risk losing the younger generation to medical scepticism in general if they continue to offer and promote flawed treatment options over effective ones. The most effective long-term treatments in musculoskeletal medicine (exercise load management and psychological reassurance) are less profitable because they require so much time investment. Health care professionals need to be true to their science background and aim to do only what is effective, not be drawn to drugs and procedures that are more profitable but ultimately more harmful.</p></div>","PeriodicalId":74029,"journal":{"name":"JSAMS plus","volume":"2 ","pages":"Article 100042"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772696723000236/pdfft?md5=55df3a9107e328b8c3ff4498bb61f0f6&pid=1-s2.0-S2772696723000236-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91987000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
