by Patrick Richardson Earlier this month — and without fanfare — the Kansas Department of Health and Environment’s Health and Environmental Laboratories reduced the cycle threshold for its real-time COVID-19 test from 42 to 35 cycles. (The screengrab below shows KDHE mistakenly dated the change January 2020, but the link address is dated 2021 and KDHE wasn’t running COVID […]
SARS-CoV-2/COVID-19 virus PCR Ct Cutoff Values January 7, 2021 The Kansas Health and Environmental Laboratories (KHEL) use real-time PCR (RT- PCR) to look for the genetic material (nucleic acid) of the SARS-CoV-2 virus in patient samples. Our most commonly performed RT-PCR assay (aka test) has a Ct cutoff of 35. All assays are rigorously and […]
The last blog noted that the knee it to knee out and heel moving inwards after ground contact is the patterning seen in a backwards moving athlete (high jumper) that (correctly) loads the inside edge/big toe side of the foot in order to complete the backward trajectory needed during the sport task. The high jumper’s […]
Below is an elite-level high jumper (Janick Klausen) in slow motion displaying quality movement mechanics for jumping backward. The knee of the plant leg goes inwards as the knee goes into valgus and the hip internally rotates, the arch collapses, ankle pronates, and the heel goes inward as the hip externally rotates after takeoff. He […]
Others who suffered a non-contact ACL tear showed the same knee valgus, arch collapse, and ankle pronation seen in this video. This is a very common structural collapse seen repeatedly on social media among many different populations, including professional athletes. The upper and lower legs bones will be rotating in opposite directions and will gradually […]
Michael Jordan is a very high level athlete and was exceptionally injury resistant during his playing career. His movement mechanics have a large part to play in both his basketball excellence and lack of injury. Look for commonalities in his footwork during the execution of similar dunks in the three videos below. Jordan repeatedly utilizes […]
