Crosscut saw into the wood. Many sawtooth patterns have four cutters; each cutter that cuts to the left of the blade is paired with another that cuts to the right of the blade. Adjacent to the cutters there is generally a raker. The void on either side of the raker is known as the gullet. A raker is what does the actual removal of the wood that is being cut. The raker follows the cutters, paring the bottom of the kerf like a chisel or plane. As the raker pares the bottom of the kerf, a strip of wood is lifted upward,
Toe walking ankle rockers. The Pomarino classification identifies the toe walking according to the individual's specific characteristics and characterizes them into three types based on the signs presented. Diagnosis includes a spin test, walking, heel walking, dorsiflexion range of motion, and lumbar lordosis. Some treatment options include serial casting and surgery for ankle motion. Studies have been performed to determine the source of the association between toe walking and cerebral palsy patients. One study suggests that the toe walking—sometimes called an equinus gait—associated with cerebral palsy presents with an abnormally short medial and lateral gastrocnemius and soleus—the primary muscles involved in plantarflexion.
