The typical tremor observed in Parkinson's disease usually occurs at rest, starts on one side of the body, and resembles the rhythmic 'pill-rolling' movement of the thumb and index finger. This tremor can be one of the first symptoms of the disease. In addition to tremor, patients may also exhibit other motor symptoms such as rigidity (stiffness) in the joints during movement, micrographia (small handwriting), bradykinesia (slowness of movement), shuffling steps and general gait disturbances, as well as a stooped posture.
