AMS 14 C age determinations of Rapanui (Easter Island) wood sculpture: moai kavakava ET 48.63 from Brussels

International audienceDirect dating, using the Accelerator Mass Spectrometry (AMS) 14 C method, of a wooden moai kavakava (anthropomorphic woodcarving) in the collection of the Royal Museums of Art and History in Brussels has given a date of about cal AD 1390–1480. As there are reasons to believe that this age not only regards the raw material but also the carving itself, preserved examples of Easter Island wood sculpture may be much older than previously assumed and possibly contemporaneous with the giant monolithic sculpture of the first half of the 2nd millennium AD

Dating Egypt's oldest 'art': AMS14C age determinations of rock varnishes covering petroglyphs at El-Hosh (Upper Egypt)

Direct dating, using the Accelerator Mass Spectrometry (AMS) C-14 dating method, indicates that some petroglyphs (rock art) at El-Hosh in Upper Egypt pre-date the early 7th millennium BP (mid 6th millennium cal BC), making it the oldest graphic activity recorded in the Nile Valley

Effects of elastic kinesiology taping on shoulder proprioception: a systematic review

Supplementary materials are available online at: https://www.sciencedirect.com/science/article/pii/S1413355523000357?via%3Dihub#sec0026 .Background: Shoulder injuries are associated with proprioceptive deficits. Elastic kinesiology tape (KT) is used for treating musculoskeletal disorders, including shoulder injuries, as it arguably improves proprioception. Objective: To synthesize the evidence on the effects of elastic KT on proprioception in healthy and pathological shoulders. Methods: Four databases (PubMed, WoS, CINAHL, SPORTDiscus) were searched for studies that investigated the effects of elastic KT on shoulder proprioception. Outcome measures were active joint position sense (AJPS), passive joint position sense (PJPS), kinesthesia, sense of force (SoF), and sense of velocity (SoV). Risk of bias (RoB) was assessed using the Cochrane Collaboration RoB tool for randomized controlled trials (RCTs), and the ROBINS-1 for non-RCTs, while the certainty of evidence was determined using GRADE. Results: Eight studies (5 RCTs, 3 non-RCTs) were included, yielding 187 shoulders (102 healthy and 85 pathological shoulders). RoB ranged from low (2 studies), moderate (5 studies), to high (1 study). Elastic KT has a mixed effect on AJPS of healthy shoulders (n=79) (low certainty). Elastic KT improves AJPS (subacromial pain syndrome and rotator cuff tendinopathy, n=52) and PJPS (chronic hemiparetic shoulders, n=13) among pathological shoulders (very low certainty). Elastic KT has no effect on kinesthesia among individuals with subacromial pain syndrome (n=30) (very low certainty). Conclusion: There is very low to low certainty of evidence that elastic KT enhances shoulder AJPS and PJPS. The aggregate of evidence is currently so low that any recommendation on the effectiveness of elastic KT on shoulder proprioception remains speculative
