s tend to flex the forefoot when kneeling or squatting, East Asians are more likely to keep the foot flat on the ground. In the two common styles of kneeling, the
plantarflexed kneel and the dorsiflexed kneel, the lead leg may experience higher
adduction and flexion moment, which is associated with increased knee joint loads.
Risk of osteoarthritis There is increased incidence of knee
osteoarthritis among squatters who squat for hours a day for many years. There is evidence that sustained squatting may cause bilateral
peroneal nerve palsy. For societies who rarely squat, squatting as a different posture may bring health benefits.
In patients with tetralogy of Fallot Toddlers and older children with the congenital heart disease
tetralogy of Fallot will often instinctively squat during a "tet spell" (an episode involving a sudden development of blue skin, caused by a drop of oxygen in the blood), allowing more blood to flow to the lungs. Squatting increases
systemic vascular resistance and allows for a temporary reversal of the
shunt. It increases pressure on the left side of the heart, decreasing the
right to left shunt thus decreasing the amount of deoxygenated blood entering the systemic circulation.
Squatting facets The existence of squatting facets on the
distal tibia and
talar articular surfaces of skeletons, which result from contact between the two bones during
hyperdorsiflexion, have been used as markers to indicate if that person habitually squatted. == Childbirth position ==
