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.
More states are passing laws that allow people to use medical marijuana. So what does it treat, and who can and should use it?

It could be from headaches, a disease like cancer, or a long-term condition, like glaucoma or nerve pain.
