Figure 2From: Comparison of knee motion on Earth and in space: an observational studyTypical histograms of the instantaneous angular position of the knee joint. Data for both subjects are shown (A) on Earth and (B) onboard the International Space Station (ISS). On Earth 73.0 ± 11.5% of the instantaneous knee angles occurred <15° and >75° ; onboard the ISS 74.6 ± 8.9% occurred within 15–75°).Back to article page
