In the initial position, the swimmer lies flat on their back; arms stretched forward, and legs extended backwards. In backstroke, the arms contribute most of the forward movement. The arm stroke consists of two main parts: the power phase (consisting of three separate parts) and the recovery. The arms alternate so that always one arm is underwater while the other arm is recovering. One complete arm turn is considered one cycle.
Some of these movement disorders that are candidates for marijuana-based therapies include dystonias, Huntington's disease, Parkinson's disease, and Tourette's syndrome. It is equally important to remember that anxiety and stress are likely to aggravate movement disorders symptoms.
What Is Medical Marijuana? Medical marijuana is any part of the marijuana plant that you use to treat health problems. People use it to get relief from their symptoms, not to try to get high. Most marijuana that's sold legally as medicine has the same ingredients as the kind that people use for pleasure. But some medical marijuana is specially grown to have less of the chemicals that cause feelings of euphoria.
