Sahelanthropus may have walked on two legs. The oldest evidence for walking on two legs comes from one of the earliest humans known, Sahelanthropus. Walking upright may have helped this species survive in the diverse habitats near where it livedâincluding forests and grasslands.
Walking frames tend to be used by those with poor balance and/ or weak legs. A walking stick can off-load 25 percent of the userâs weight compared to a frame which can transfer 64 percent of the user's weight through the arms . This weight re-distribution from legs to arms can help reduce leg pain.
