could possibly induce the external rotation and anterior translation of the MTs with increasing axial loading. During walking, the vertical ground reaction moment is applied to the foot in the direction of external rotation in the first half and in the direction of internal rotation in the second half of the stance phase, respectively \[[@RSOS171086C43]--[@RSOS171086C45]\]. The structurally embedded capacity of the human foot to generate tibial internal rotation and MT\'s external rotation may possibly facilitate compensation of the moment generated around the vertical axis of the body during walking owing to trunk rotation and leg swing. Elucidating the possible contribution of the foot structure on generation of a vertical free moment for stable bipedal locomotion would be an important area of future studies.

Two people are believed to have been killed after a crane collapsed at the site of a World Cup stadium in Brazil.

The incident happened at the construction site of the Corinithians Arena in Sao Paolo, which will host the opening game of the tournament next year.

Work has been ongoing at the ground and was due to be completed by the end of December.

However, Lancenet reports that a crane, which was parked outside the stadium, suddenly collapsed at around midday local time – due to unstable soil following a rain storm.


The stadium was
