The great toe should dorsiflex with a significant amount of strength and the examiner should not be able to oppose this motion easily. The common causes of great toe dorsiflexion weakness are a peroneal nerve palsy or an L5 radiculopathy.
The âvertical limitâ is defined as the highest altitude at which humans can survive. This altitude is generally understood to be approximately 18,000 feet above sea level. If humans spend time above this altitude, their health gradually declines due to a lack of oxygen and lower barometric pressure.his altitude is generally understood to be approximately 18,000 feet above sea level.
